Buy-side security teams spent most of 2026 asking the same question in different words: which secure access service edge platform actually deserves the budget line. The four names that keep surfacing in shortlists are Zscaler Zero Trust Exchange, Netskope One, Cloudflare One and Palo Alto Networks Prisma Access, and the gaps between them are no longer cosmetic. Zscaler now runs more than 200 public data centers against Netskope’s 120-plus full-compute sites, a roughly 80-location footprint gap that shapes latency, failover and contract leverage all at once. Add in a Gartner Magic Quadrant where three of the four land in the Leaders box and one sits in Niche Players, and the shortlist stops being a coin flip.
This comparison pulls apart secure access service edge (SASE) architecture, published uptime figures, Gartner and G2 standing, pricing structure and five sourced case studies with real numbers attached. The goal is a buying decision, not a feature checklist. Every figure below is tied to a dated source, and where a vendor has not published a number, that gap is called out rather than filled in with a guess.
What SASE Actually Means Heading Into 2026
Secure access service edge combines networking and security into a single cloud-delivered layer. The networking half typically includes SD-WAN and a backbone connecting branches, data centers and remote users. The security half bundles secure web gateway (SWG), cloud access security broker (CASB), zero trust network access (ZTNA) and firewall-as-a-service (FWaaS) into policies that follow the user instead of the office. When vendors talk about “SSE,” they usually mean the security half of that stack sold on its own, which is how Zscaler, Netskope, Cloudflare and Palo Alto Networks are most often ranked by analysts.
The consolidation push behind this comparison is not theoretical. Dell’Oro Group reported that security service edge revenue grew 15% year over year in a recent quarter, while secure web gateway appliance sales fell 5% over the same period, a shift the firm’s analysts described as migration away from on-premises boxes toward SSE suites, according to SDxCentral’s reporting on the Gartner rankings. MarketsandMarkets separately sized the global SASE market at $19.19 billion for 2026, projecting growth to $68.06 billion by 2032 at a 28.8% compound annual growth rate. Dell’Oro’s own longer-range forecast, published in August 2026, points to a $24 billion SASE market by 2030, growing at roughly 15% a year and more than doubling from 2025 levels, a figure available directly from Dell’Oro Group’s research pages.
Security teams are not chasing consolidation purely to cut costs, either. A Futuriom survey published in September 2026 found that 92% of respondents were actively pursuing a single-vendor or single-platform SASE strategy rather than stitching together point products. Improved security visibility and analytics ranked as the top perceived benefit of that consolidation, cited by 69% of respondents, ahead of reduced operational complexity at 58% and improved user experience and performance at 44%. The pain points pushing buyers toward a single platform are just as concrete: 44% named juggling multiple management consoles as their biggest headache, 42% cited the difficulty of troubleshooting performance issues once three or four vendors each own a slice of the traffic path, and 38% pointed to inconsistent policy enforcement across disconnected tools. Those numbers explain why “fewer vendors, one console” has become the default pitch from every platform in this comparison, not just a sales talking point.
Zscaler Zero Trust Exchange: Scale as the Pitch
Zscaler’s argument for Zero Trust Exchange starts with raw footprint. The company’s fiscal year 2026 filing, covering the period through July 31, 2026, reports more than 200 public data centers plus thousands of private edge sites serving customers in upwards of 185 countries. That same filing puts Zscaler’s customer count at approximately 11,000, with no single customer accounting for more than 10% of revenue, and reports FY2026 revenue of roughly $3.3525 billion, up about 25% from $2.6731 billion in FY2025. Zscaler’s investor materials separately cite annual recurring revenue near $3.8 billion for the fiscal year.
Zscaler’s architecture runs as a single-scan, multi-action cloud proxy rather than routing traffic through branch firewalls, which is the core of its latency pitch: inspect once, apply every policy (DLP, malware scanning, CASB rules) in that same pass, and avoid the backhaul that traditional hub-and-spoke VPN designs require. Gartner’s most recent Security Service Edge Magic Quadrant named Zscaler a Leader, crediting strong market presence, a simplified pricing scheme and continued innovation, while flagging that customers reported connectivity issues more often than is typical for other vendors in the category and that Zscaler’s value proposition extends well beyond the narrow SSE category, according to the Gartner findings summarized by SDxCentral. On G2, Zscaler Internet Access carries a 4.4 out of 5 rating across 322 reviews as of early October 2026.
The newest product push is squarely about agentic AI. Zscaler announced innovations on June 9, 2026 aimed at securing AI agents operating inside the Zero Trust Exchange, and the company has also moved to acquire Symmetry Systems to pair its zero trust access model with access-graph technology built for machine-to-machine and agent-to-agent communication. That is a meaningfully different security problem than human SSO logins, and it is the clearest signal that Zscaler expects its next growth phase to come from securing autonomous software rather than just remote employees.
Netskope One: Betting on Data, Not Just Access
Netskope’s pitch is less about raw data center count and more about what happens to data once a connection is established. The company operates more than 120 full-compute data centers under its NewEdge network, a smaller footprint than Zscaler’s but one Netskope backs with a published 99.999% uptime SLA, a target that works out to roughly 26.3 seconds of allowed downtime per 30-day month before service-credit terms kick in. Gartner named Netskope a Leader in its SSE Magic Quadrant for the fourth consecutive year, crediting strong technical capabilities and brand awareness, while also noting a historically narrow focus on large customers, limited language support in its management console and a slower pace of new feature releases relative to Zscaler, per the same SDxCentral summary of Gartner’s findings.
Netskope’s biggest 2026 move was not a new data center count, it was a data-governance product. On September 2, 2026, the company launched the Netskope One DataSec Command Center, pitched as a unified control plane for discovering, classifying and protecting sensitive data across AI tools, cloud apps, on-premises systems, endpoints and email from a single console. That launch was followed by a broader public unveiling roughly two weeks later. The framing matters: Netskope is explicitly positioning data security, rather than network access alone, as the reason to pick its platform over a pure-access play, which tracks with its long CASB heritage predating the current SASE branding.
Cloudflare One: The Network Operator’s SASE Play
Cloudflare approaches SASE from a different starting point than the other three. Rather than building a security-first overlay, Cloudflare One rides on top of a network the company already operates at massive scale, described on its own product pages as spanning hundreds of cities in more than 100 countries, a scale advantage Cloudflare argues shows up as lower round-trip latency for globally distributed teams, detailed at Cloudflare’s network overview. That architecture puts Cloudflare closer to a traditional CDN or DDoS-protection vendor that grew into zero trust access, rather than a zero trust vendor that later built out networking.
Gartner’s most recent SSE Magic Quadrant placed Cloudflare in the Niche Players quadrant, alongside Versa Networks, Broadcom, iboss and Skyhigh Security, a tier below the Leaders occupied by Zscaler, Netskope and Palo Alto Networks, per SDxCentral’s reporting on the ranking. That standing is worth weighing against Cloudflare’s pricing, which is the most transparent of the four by a wide margin: Cloudflare publishes a free Zero Trust tier covering up to 50 users, a pay-as-you-go tier priced at $7 per user per month when billed annually, and a custom-priced Contract tier for full SASE deployments, figures published directly on Cloudflare’s pricing materials as of October 2026.
Cloudflare also ships updates on a visibly faster cadence than the enterprise-sales-driven rivals on this list. The Cloudflare One client reached version 2026.8.2100.0 across Windows, macOS and Linux on October 7, 2026, and two days earlier, on October 5, 2026, Cloudflare changed the default security posture for newly created Zero Trust organizations so that strict service-token authentication is enabled by default and cannot be disabled, a move documented in the company’s own October 2026 changelog. That is a meaningful security-by-default shift, and it suggests Cloudflare is tightening its zero trust defaults ahead of broader enterprise scrutiny rather than waiting for a breach to force the change.
Palo Alto Networks Prisma Access: The Platform Consolidation Bet
Prisma Access is Palo Alto Networks’ argument that SASE buyers should not treat network security and endpoint security as separate purchases. The platform combines SSE capabilities with SD-WAN on what Palo Alto Networks describes as a hyperscale backbone, detailed on the company’s own Prisma Access product page, and it is sold as part of a broader platform that also spans next-generation firewalls and cloud-delivered security services. Gartner named Prisma Access a Leader in its SSE Magic Quadrant, citing strong market presence, AI integration plans and simplified integration with Palo Alto’s other products, while flagging a relatively narrow set of supported use cases, complex pricing models and limited language support as drawbacks, per SDxCentral’s summary of the ranking.
Palo Alto Networks backed up that Leader ranking with two carrier-scale wins reported in 2025: AT&T selected the company to power a higher tier of its Dynamic Defense cybersecurity service, and T-Mobile US added Prisma Access as an option inside its own managed SASE offering. On the independent testing side, Prisma Access’s SSE platform blocked 100% of evasion attempts in a recent CyberRatings.org evaluation, a clean result on a test category where many security products leak traffic. On G2, Prisma Access sits at 4.3 out of 5 across 73 reviews as of early October 2026, fewer reviews than Zscaler but a comparably strong score.
Specs Comparison: Zscaler vs Netskope vs Cloudflare One vs Prisma Access
The table below lines up the four platforms on the metrics buyers actually ask about during procurement. Where a vendor has not published a comparable figure, that is marked rather than estimated.

Pricing and Licensing: What Each Platform Actually Costs to Deploy
SASE pricing is notoriously opaque, and that opacity is itself a data point worth flagging to any buyer comparing these four platforms. Three of the four vendors here do not publish a list price at all, which is standard for enterprise security but still frustrating for a mid-market team trying to budget before a sales call.
| Platform | Pricing model | Free tier | Published per-user rate | Typical buying motion |
|---|---|---|---|---|
| Zscaler Zero Trust Exchange | Subscription with consumption-based add-ons; some products metered by traffic volume rather than purely per seat | No | Not publicly listed | Enterprise sales cycle, multi-year contract |
| Netskope One | Enterprise quote-based licensing across bundled platform tiers | No | Not publicly listed | Enterprise sales cycle, multi-year contract |
| Cloudflare One | Published tiers: Free, Pay-as-you-go, Contract | Yes, up to 50 users | $7 per user/month (Pay-as-you-go, billed annually) | Self-service signup for small teams; sales-assisted for Contract tier |
| Prisma Access | Quote-based licensing, often bundled with broader Palo Alto Networks platform credits | No | Not publicly listed; Gartner specifically flagged pricing complexity | Enterprise sales cycle, platform-wide negotiation |
Cloudflare’s willingness to post a per-seat number in public is the single clearest differentiator in this section. A 50-person startup can self-serve Cloudflare One without talking to a sales rep, run a real pilot, and only scale into the Contract tier once usage demands it. Zscaler, Netskope and Prisma Access all route serious evaluations through an account team, which makes sense for a platform sized for tens of thousands of seats but adds friction for anyone trying to get a rough budget number on day one.
That opacity has a direct effect on how long a deal takes to close. A pay-as-you-go tier with a posted $7-per-user rate can be approved inside a department’s existing software budget without legal or procurement sign-off. A quote-based enterprise contract, by contrast, typically runs through a security review, a legal redline cycle and a multi-year commitment negotiation, which is exactly why Zscaler, Netskope and Prisma Access are sold almost exclusively to organizations with a dedicated procurement function and a security team large enough to run a formal RFP. Buyers evaluating any of the three quote-based platforms should ask for a traffic-based cost model up front, since Zscaler in particular prices some of its offerings by data volume rather than strictly by headcount, which can make seat-based budget comparisons misleading if the usage pattern is unusually bandwidth-heavy.
Benchmarks and Independent Rankings: Reading Past the Marketing
No single benchmark settles this comparison, which is exactly why it is worth triangulating across more than one source. Gartner’s Security Service Edge Magic Quadrant remains the most-cited analyst ranking in this category, and its latest edition put Zscaler, Netskope and Palo Alto Networks in the Leaders quadrant while placing Cloudflare, Versa Networks, Broadcom, iboss and Skyhigh Security in Niche Players, with Fortinet alone occupying Challengers, according to SDxCentral’s detailed breakdown of the report. That same reporting notes Gartner also listed Cisco, Microsoft, Check Point, HPE-Aruba and Lookout as honorable mentions that did not meet the firm’s release-date or scale thresholds for an official ranking.
Gartner is not the only analyst voice in this market, and the other two tracked in that same SDxCentral piece largely agree on the top tier while disagreeing on the edges. Forrester’s SSE Wave report named the same three vendors as leaders plus Forcepoint, and GigaOm’s Radar for SSE extended the leader label to Zscaler, Netskope and Palo Alto Networks while also including Versa, Cato Networks, Cloudflare and Skyhigh Security. The practical read: there is near-universal analyst agreement that Zscaler, Netskope and Palo Alto Networks lead the category, while Cloudflare’s standing varies more by which firm is doing the ranking and which weighting they apply to pure security-service maturity versus network scale.
On the review-site side, G2’s current Zero Trust Platforms category reports an overall average rating of 4.49 out of 5 across all listed vendors, with Zscaler Internet Access (4.4/5, 322 reviews) and Prisma Access (4.3/5, 73 reviews) both landing close to that category average. Netskope’s and Cloudflare’s current product-specific scores were not reliably exposed in the review snapshot pulled for this comparison, which is itself worth noting: review volume and visibility vary enough between these platforms that G2 alone should not be the deciding factor. On third-party security testing, CyberRatings.org’s evaluation showing Prisma Access blocking 100% of evasion attempts is the strongest independent technical benchmark available among the four platforms in current public research, and no equivalent public CyberRatings.org score was found for the other three vendors in this comparison.
Real-World Deployments: Five Case Studies With Numbers
Public, numbers-attached case studies for this category skew heavily toward one vendor. Zscaler’s customer-story library is the most detailed source of dated, quantified deployment results found in current research; Netskope, Cloudflare and Prisma Access deployments tend to stay behind NDAs or get summarized only in carrier press releases, which is itself a useful signal about how each vendor manages its reference-customer program. The five examples below are drawn from that research.
NOV: Oilfield Equipment, 35x Fewer Cyber Events
NOV, an oilfield equipment and energy technology company, migrated from traditional network-access infrastructure to Zscaler Zero Trust Exchange, rolling out policy-based access for employees and contractors working from anywhere. The company reported 35 times fewer cyber events after the migration, access extended to more than 7,500 applications, network performance improvements of 10 to 20 times, and cost reductions exceeding 4 times prior spend. Annualized circuit savings topped $4.5 million while the transition was roughly 75% complete, according to Zscaler’s published customer stories.
NTT DATA: 50,000 Users Onboarded in 30 Days
NTT DATA deployed Zscaler first across North America and then globally as part of a broader zero trust architecture rollout meant to unify previously separate operating companies under one access model. The initial phase onboarded 50,000 people in 30 days, with the wider program targeting roughly 150,000 users migrated to a consistent global security and access standard, per NTT DATA’s own account of the project published July 29, 2026.
Mindbody: VPN Replacement at 5x the Speed
Mindbody, a wellness and fitness software company, used Zscaler Zero Trust Exchange to reduce reliance on VPN-based remote access while simultaneously migrating from an on-premises data center to AWS. Post-acquisition employee onboarding became 50% faster, access provisioning dropped from days or weeks to minutes, and remote access deployment ran 5 times faster than the company’s previous VPN process, with reduced VPN spending reported as a secondary benefit, according to Zscaler’s customer story library.
A Middle Eastern Technology Firm: 55% Lower Infrastructure Cost
A technology company in the Middle East, not publicly named in Zscaler’s case study, used a Zscaler-based zero trust model to support a post-merger integration, reporting a 55% reduction in annual infrastructure costs after consolidating separate networks under a single access framework.
Zero Trust Branch: Up to 43% Savings From Retiring Firewalls
A separate, unnamed enterprise customer in Zscaler’s portfolio replaced branch-firewall-dependent security with Zscaler Zero Trust Branch, phasing out physical firewalls at branch locations entirely. The company reported cost savings of up to 43% after making the switch, illustrating the capital-expense argument SASE vendors make against refreshing aging branch hardware.
Who Should Pick Which SASE Platform
The right platform depends more on existing infrastructure and team size than on any single benchmark score. The five scenarios below map the most common buyer profiles onto the vendor that fits best given the data in this comparison.
Global enterprises prioritizing proven ROI documentation
Organizations that need to justify a SASE migration to a finance committee benefit from Zscaler’s depth of publicly documented, numbers-attached case studies. The NOV, NTT DATA and Mindbody examples above give a procurement team real precedent to point to, which matters more than it should in large budget approvals.
Data-heavy organizations with complex SaaS and AI exposure
Companies whose biggest risk is sensitive data leaking through SaaS apps, generative AI tools or shadow IT are better served by Netskope’s CASB-rooted architecture and the new DataSec Command Center, which was purpose-built to classify and govern data across AI environments rather than just control network access.
Startups and mid-market teams under 50 seats
Cloudflare One’s free tier for up to 50 users removes the biggest barrier to testing a real SASE deployment: a sales cycle. A 30-person engineering team can be running zero trust access policies the same afternoon they sign up, with a clear, published price to scale into once headcount grows past the free threshold.
Palo Alto Networks platform shops and carriers
Enterprises already standardized on Palo Alto Networks next-generation firewalls get the clearest integration story from Prisma Access, and the AT&T and T-Mobile US wins show the platform scales to carrier-grade managed security offerings, not just direct enterprise contracts.
Branch-heavy retail and distributed-location businesses
Businesses with dozens or hundreds of physical branches facing firewall refresh cycles should weigh Zscaler Zero Trust Branch against a hardware replacement budget. The up to 43% savings reported from retiring branch firewalls entirely is a direct counter to the usual “just buy more firewalls” default.
Regulated industries that need independent test validation
Banks, insurers and healthcare organizations that have to defend a security architecture decision to an auditor or regulator benefit from a platform with a published, independently verified test result rather than vendor-reported marketing claims. Prisma Access’s 100% evasion-blocking score from CyberRatings.org is the one hard, independently sourced technical benchmark in this entire comparison, which makes it an easier number to put directly into a compliance narrative than an internal performance claim from any vendor’s own lab.
Migrating to a SASE Platform: A Practical Guide
Every vendor above sells migration as a phased project, not a cutover weekend, and the published case studies back that up: NOV’s rollout was still at 75% completion when its results were reported, and NTT DATA’s full 150,000-user target extended well beyond the initial 50,000-user, 30-day phase. The steps below reflect the common pattern across these deployments regardless of which platform a team picks.
- Inventory existing VPN concentrators, branch firewalls and CASB tools to identify what the new platform needs to replace versus what it needs to integrate with.
- Map identity sources (Entra ID, Okta, Ping) into the new platform’s identity provider integration before touching any access policy.
- Run a limited proof-of-concept with one business unit or office, sized to validate latency and application compatibility, not full-scale rollout.
- Build access policies around application identity and user risk rather than network location, since that is the core assumption the entire SASE model depends on.
- Stand up logging and SIEM integration early so the security team has visibility during the transition, not just after it finishes.
- Phase the cutover by location or business unit, following the pattern NTT DATA and NOV both used, rather than attempting a single global switch.
- Decommission legacy VPN concentrators and branch firewall hardware only after a full policy audit confirms parity, to avoid a security gap during the handoff.
- Re-baseline cost and performance metrics 90 days post-migration to produce the kind of documented ROI figures finance teams expect to see.
Access policies in every one of these platforms ultimately reduce to a structured rule set tying an identity, a device posture check and an application together. A simplified, illustrative example of that structure looks like this:
policy:
name: "finance-app-access"
identity:
group: "finance-team"
mfa_required: true
device:
posture_check: "managed-and-patched"
application:
target: "internal-finance-portal"
access_mode: "zero-trust-network-access"
action: "allow"
logging: "full"That structure is deliberately generic. Each vendor’s actual policy syntax differs, but the underlying logic, identity plus device posture plus application equals an explicit allow or deny decision, is consistent across Zscaler, Netskope, Cloudflare One and Prisma Access, and it is the piece of the migration that takes the most planning time regardless of which platform a team selects.
Pros and Cons of Each Platform
Zscaler Zero Trust Exchange
Pros: largest data center footprint among the four at 200+ locations, Gartner Leader status, the deepest bench of public case studies with hard numbers, and an early, aggressive push into agentic AI access security backed by the pending Symmetry Systems acquisition.
Cons: Gartner specifically flagged connectivity issues reported more frequently than typical for the category, no public free tier for smaller teams to test the platform, and pricing that requires a full enterprise sales cycle to understand.
Netskope One
Pros: four consecutive years as a Gartner Leader, a published 99.999% uptime SLA, deep CASB and data-security heritage, and the new DataSec Command Center built specifically for AI-era data governance.
Cons: smaller data center footprint than Zscaler, Gartner-flagged narrow historical focus on large customers, limited console language support, and far fewer publicly available case studies with specific performance numbers.
Cloudflare One
Pros: the only platform here with a published free tier (up to 50 users) and a public per-seat price, a massive underlying global network spanning hundreds of cities, and a fast public release cadence that puts security defaults like mandatory service-token authentication in place proactively.
Cons: sits in Gartner’s Niche Players quadrant rather than Leaders, limited publicly available enterprise case studies with hard numbers, and a network-operator heritage that is architecturally different from the purpose-built SSE stacks of the three Leaders.
Prisma Access
Pros: Gartner Leader status, a clean 100% evasion-blocking result from CyberRatings.org, carrier-scale validation through the AT&T and T-Mobile US deals, and tight integration for shops already running Palo Alto Networks firewalls.
Cons: Gartner specifically called out complex pricing models and a relatively narrow set of supported use cases, limited language support, and fewer independently documented customer case studies than Zscaler in current public research.
The SASE Market Outlook for the Rest of 2026
Every market estimate in current circulation points the same direction: up and faster than legacy network security spending. MarketsandMarkets’ $19.19 billion 2026 market size, growing to $68.06 billion by 2032, implies a market that will more than triple in size over the next six years. Dell’Oro’s more conservative $24 billion-by-2030 forecast still represents more than a doubling from 2025 levels. Both estimates sit on top of the same underlying trend reported from Gartner’s survey data: the strongest pull toward consolidation is coming from security effectiveness and operational simplicity, not primarily cost-cutting, which suggests the current crop of Leaders has room to keep raising prices faster than a purely commoditized market would allow.
Cloudflare’s move to default-on strict service-token authentication for new Zero Trust organizations as of October 5, 2026 is worth watching as a bellwether. If Gartner’s next Magic Quadrant update rewards that kind of proactive hardening, Cloudflare has a credible path toward the Leaders quadrant in subsequent cycles, closing the gap with Zscaler, Netskope and Palo Alto Networks faster than its current Niche Player standing suggests.
The Verdict: No Single Winner, Four Clear Fits
Treat this as a decision tree, not a leaderboard. Zscaler wins on scale, documented ROI and Gartner’s highest execution marks, and it is the safest default for large global enterprises that need to show finance a paper trail of comparable deployments. Netskope wins for organizations where sensitive data governance across SaaS and AI tools matters more than raw network footprint, backed by the only published 99.999% SLA in this comparison. Cloudflare One wins on accessibility and transparency, the only platform here a 30-person team can actually afford to pilot without a sales call, even though it trails the other three on Gartner’s analyst scoring. Prisma Access wins for Palo Alto Networks shops and carriers that need a validated, carrier-grade SASE option bundled into a broader security platform they already run.
The 80-plus data center gap between Zscaler and Netskope, the 99.999% SLA Netskope publishes and nobody else here matches, and the $7-per-user price Cloudflare puts in public while three rivals keep theirs behind a sales wall, those three numbers alone tell most of the story a procurement team needs heading into a 2026 SASE evaluation.
Frequently Asked Questions
What does SASE stand for, and how is it different from a VPN?
SASE stands for secure access service edge. Unlike a traditional VPN, which routes all traffic back through a central corporate network before reaching the internet or cloud apps, SASE applies security policy at distributed points of presence close to the user, combining SD-WAN, ZTNA, SWG, CASB and firewall-as-a-service into one cloud-delivered service rather than backhauling every connection.
Which SASE platform has the best Gartner ranking in 2026?
Zscaler, Netskope and Palo Alto Networks Prisma Access were all named Leaders in Gartner’s most recent Security Service Edge Magic Quadrant. Cloudflare landed in the Niche Players quadrant in the same report, according to SDxCentral’s coverage of the rankings.
Is there a free way to try a SASE platform before buying?
Cloudflare One is the only platform in this comparison with a published free tier, covering up to 50 users at no cost. Zscaler, Netskope and Prisma Access do not publish a free tier and typically require an enterprise sales conversation or a sponsored proof-of-concept to evaluate.
How much does Zscaler, Netskope or Prisma Access actually cost?
None of the three publishes a public per-seat price list. All three use quote-based enterprise pricing that varies by user count, bandwidth, modules and contract length, and Gartner specifically flagged Palo Alto Networks’ Prisma Access pricing structure as complex relative to competitors.
How long does a typical SASE migration take?
Public case studies suggest phased rollouts measured in months, not weeks, for full enterprise deployments. NTT DATA onboarded an initial 50,000 users in 30 days as part of a program ultimately targeting roughly 150,000 users, while NOV’s migration was still at 75% completion when its results were reported.
Does a SASE platform completely replace firewalls and VPNs?
It can. Zscaler’s Zero Trust Branch product is specifically designed to let branch locations retire physical firewalls entirely, with one documented customer reporting savings of up to 43% after doing so. Most organizations still run a phased approach, keeping some legacy hardware during the transition rather than cutting over all at once.
What is the difference between SSE and SASE?
SSE, or security service edge, refers to the security half of the SASE stack: SWG, CASB, ZTNA and FWaaS. SASE adds the networking half, primarily SD-WAN and a connectivity backbone, on top of SSE. Gartner ranks these vendors separately in its SSE Magic Quadrant specifically because some buyers only need the security layer and already have networking handled elsewhere.
Which platform is best for a small business or startup?
Cloudflare One is the most practical starting point for organizations under 50 seats, given its free tier and self-service signup. Teams that outgrow that threshold can move into Cloudflare’s $7-per-user Pay-as-you-go tier before considering a full enterprise contract with any of the four platforms covered here.
