The SWG Is Not Your Differentiator Anymore
If you are scoring SASE vendors and the Secure Web Gateway line item is where you expect the field to separate, you are looking in the wrong place. It does not.
We ran 5 core SWG checks across all 8 leading SASE platforms: full SSL/TLS decryption, cloud sandboxing for zero-day malware, granular URL filtering, browser isolation for risky sites, and real-time phishing detection. The result is the tightest cluster of any category we test. Cato Networks scores a clean 100%. Everyone else lands between 80% and 90%. There is no vendor here that cannot decrypt HTTPS, filter by category, or detonate a suspicious download in a sandbox. Those capabilities are table stakes in 2026.
That is the story buyers need to hear, because SWG is still a mandatory line in every SASE RFP and vendors still price it like a differentiator. It is not. The differentiation has moved into the caveats: whether TLS decryption is full or hedged, whether browser isolation is native and included or a separately-licensed add-on, whether sandboxing is bundled or gated behind a higher tier, and whether phishing detection actually analyzes the live page or just checks a reputation list.
This post is also for readers searching "sase swg" and trying to figure out what the term even buys them. Short answer: less unique value than the marketing implies. Here is where the real gaps hide.
The Scorecard
| Rank | Vendor | YES | PARTIAL | NO | Score |
|---|---|---|---|---|---|
| 1 | Cato Networks | 5 | 0 | 0 | 100% |
| 2 | Zscaler | 4 | 1 | 0 | 90% |
| 2 | Palo Alto Networks | 4 | 1 | 0 | 90% |
| 2 | Netskope | 4 | 1 | 0 | 90% |
| 2 | Fortinet | 4 | 1 | 0 | 90% |
| 2 | Check Point | 4 | 1 | 0 | 90% |
| 7 | Cloudflare | 3 | 2 | 0 | 80% |
| 7 | Cisco | 3 | 2 | 0 | 80% |
A 20-point spread across 8 vendors on a foundational category is nothing. Read this scorecard as a green light on the basics, not as a ranking of who has the best web security. The single YES that separates Cato from the pack, and the PARTIAL answers that pull Cloudflare and Cisco down, are the only lines worth arguing about. Everything else is parity.
Check 1: Full SSL/TLS Decryption -- Universal, With Architecture Differences
Over 90% of web traffic is encrypted. A SWG that cannot decrypt is blind to most threats.
All 8 vendors score YES. This is fully commoditized.
| Vendor | Score | Key Detail |
|---|---|---|
| Cato Networks | YES | Full TLS 1.1/1.2/1.3 decrypt at the PoP across all engines, then re-encrypt; scales to multi-gig streams inline |
| Zscaler | YES | Full SSL forward proxy, TLS 1.0-1.3 with PFS; single-scan multi-action pass to limit latency |
| Netskope | YES | Cloud decryption at scale, single-pass parallel checks; all steered traffic decrypted by default |
| Palo Alto Networks | YES | SSL Forward Proxy on all ports as a policy decision, feeding Content-ID, URL Filtering, WildFire, DLP |
| Fortinet | YES | Full deep inspection including TLS 1.3, DPI enabled per SWG proxy profile group |
| Check Point | YES | Basic and Full Inspection modes; hybrid model can inspect client-side to cut backhaul latency |
| Cloudflare | YES | In-memory decrypt at the edge (no disk write); pinned/mTLS/ECH traffic are the exceptions |
| Cisco | YES | Full cloud proxy HTTPS decryption feeding DLP, file inspection, IPS, RBI; no published latency figure |
The takeaway: everyone can decrypt. The real questions are architectural, not binary. Where does decryption happen (cloud PoP versus client-side), does it cover all ports or just 443, and what is the documented performance and exception list. Check Point's client-side inspection option and Cloudflare's in-memory edge model are genuinely different design choices, but no vendor fails the capability. Do not let a demo of "we do SSL inspection" impress you. Ask for the exception list and the throughput numbers instead.
Check 2: Cloud Sandboxing -- Watch the Licensing Tier
Signature detection misses zero-days. Sandboxing detonates suspicious files in isolation before delivery.
Seven vendors score YES. Cloudflare is the only PARTIAL.
| Vendor | Score | Key Detail |
|---|---|---|
| Cato Networks | YES | NG Anti-Malware (with SentinelOne) plus Cato Cloud Sandbox; nested archives held until fully scanned |
| Zscaler | YES | Inline static and dynamic analysis with AI Instant Verdict; patient-zero inline blocking needs Advanced add-on |
| Palo Alto Networks | YES | Advanced WildFire natively integrated, dynamic and static plus ML, including files over encrypted web |
| Netskope | YES | Cloud Sandbox (licensed ATP tier), 30+ file types, Patient Zero hold up to ~10 min |
| Fortinet | YES | FortiSandbox plus FortiGuard Inline Malware Prevention, sub-second verdict hold, bundled with FortiSASE |
| Check Point | YES | Threat Emulation (SandBlast) cloud sandbox backed by ThreatCloud AI |
| Cisco | YES | Secure Malware Analytics (Threat Grid) detonation; needs SIG Essentials or higher and File Inspection on |
| Cloudflare | PARTIAL | Detonates unseen files that pass AV, but gated as an Enterprise add-on and excludes files over 100 MB and PGP-encrypted files |
The takeaway: the capability is near-universal, but "included" is not. Zscaler gates true patient-zero inline blocking behind an Advanced Sandbox add-on, Netskope's sandbox lives in a licensed ATP tier, Cisco needs SIG Essentials, and Cloudflare's sandbox is an Enterprise-plan add-on with hard file-size and encryption exclusions. The YES on a datasheet and the YES in your quoted SKU are frequently different things. This is exactly the kind of caveat that a raw score hides. See the threat prevention comparison for how these sandboxing engines feed the broader malware stack.
Check 3: Granular URL Filtering -- Fully Table Stakes
Marketing needs social media. Engineering does not. Per-user policies prevent blanket blocks that hurt productivity.
All 8 vendors score YES. This is the most commoditized check in the set.
| Vendor | Score | Key Detail |
|---|---|---|
| Cato Networks | YES | 80+ categories, scoped by user, group, location, device posture; best-practice defaults |
| Netskope | YES | 120+ predefined categories (docs cite ~150), 300M+ URL database, per user/group/device/location |
| Fortinet | YES | FortiGuard 90+ categories, hundreds of millions of URLs, identity-based rules via profile groups |
| Zscaler | YES | Well over 80 predefined categories plus 64 custom, scoped by user/group/dept/device/location/time |
| Cisco | YES | 80+ content categories over millions of domains, per network/IP/group/user/device, location-aware |
| Cloudflare | YES | ~24 content categories with subcategories plus 13+ security categories (past 80 total), per user/group/posture |
| Palo Alto Networks | YES | PAN-DB ~75 categories, up to 4 per URL, plus risk ratings, custom categories, user/group identity |
| Check Point | YES | Millions of sites by category, user, group, machine; docs cite site count, not an exact category number |
The takeaway: every vendor does granular, identity-aware URL filtering. Category counts range from Cloudflare's roughly two dozen content categories to Netskope's 120+, but every platform clears the 80-category bar that RFPs traditionally ask for (Cloudflare gets there by combining content plus security categories, and Palo Alto's ~75 sits just under). Category count is a vanity metric past a point. The database freshness and how cleanly policies bind to your IdP groups matter far more than the headline number. If a vendor leads with "we have the most categories," you are being sold table stakes.
Check 4: Browser Isolation -- Native vs Add-On Is the Real Split
Uncategorized sites are high risk. Isolation renders them safely without blocking, so security without user complaints.
This is the check that actually separates the field, and not on a YES/NO basis. It splits on packaging.
| Vendor | Score | Key Detail |
|---|---|---|
| Cato Networks | YES | RBI integrated into the platform, auto-isolates uncategorized/risky sites; a licensed premium service, not free with base SWG |
| Fortinet | YES | RBI via FortiIsolator, documented for SWG mode; requires Advanced or Comprehensive subscription tier |
| Cloudflare | YES | Isolate action native in HTTP policies, runs page code at the edge; isolates threats, risky/new domains, uncategorized |
| Zscaler | PARTIAL | Cloud Browser Isolation integrates with URL Filtering Isolate action, but needs a separately-licensed Isolation add-on |
| Netskope | PARTIAL | Targeted RBI integrated with NG SWG (powered by Ericom), but a separate add-on and licenses cap isolated traffic percentage |
| Palo Alto Networks | PARTIAL | RBI natively integrated, redirects selected categories, but needs a separate RBI add-on and is unsupported in Panorama multitenant |
| Cisco | PARTIAL | Isolate Any/Risky/Web modes with read-only rendering, but a separate SKU on top of SIG Essentials/Advantage |
| Check Point | PARTIAL | On-device Chromium Enterprise Browser and Browser Security extension, not classic cloud RBI on uncategorized sites |
The takeaway: every vendor except Check Point can isolate risky sites, and even Cato's, Fortinet's, and Cloudflare's YES answers carry a license cost. The distinction that matters: Cloudflare's isolation is a native Isolate action in the same policy engine, Cato and Fortinet integrate it cleanly (at a premium tier), while Zscaler, Netskope, Palo Alto, and Cisco all treat it as a bolt-on SKU with its own licensing, and Netskope even caps the percentage of traffic you can isolate. Check Point is the genuine outlier: its approach is device-based (an Enterprise Browser and extension), not cloud RBI that renders uncategorized sites in a disposable remote container. If browser isolation is central to your web-security strategy, this single check deserves more scrutiny than the other four combined. Dig into the browser isolation comparison before you assume it is included.
Check 5: Real-Time Phishing Detection -- The Quiet Differentiator
Phishing sites live for minutes before hitting reputation databases. Real-time page analysis catches them on first visit.
Five vendors score YES with true live-page analysis. Three lean on reputation and ML URL scoring instead.
| Vendor | Score | Key Detail |
|---|---|---|
| Cato Networks | YES | Real-time ML/heuristic analysis of page components, domain age, and toolkit patterns; reports ~6x more malicious domains than feeds alone |
| Check Point | YES | Zero Phishing injects JavaScript to scan HTML forms as they load, analyzing brand similarity and domain age via ThreatCloud AI |
| Zscaler | YES | Inline AI/ML on live page content (scripts, zero-pixel iFrames) building Page Risk and Domain Risk, not IOC-dependent |
| Netskope | YES | Deep-learning inline engine inspects full HTML, JS, and CSS in real time, sub-10ms, catching patient-zero phishing |
| Palo Alto Networks | YES | Local inline ML plus cloud deep learning on actual page content, catching cloaked and one-time-use URLs |
| Fortinet | PARTIAL | AI-driven URL/domain classification in near real time, but documented as classification, not rendered-page analysis |
| Cisco | PARTIAL | Blocks at DNS/IP with Talos reputation and ML domain scoring, routing risky domains to the Intelligent Proxy; no dedicated page-render engine |
| Cloudflare | PARTIAL | Phishing security category is reputation/ML-derived; true real-time page analysis is documented for Email Security, not the inline web SWG path |
The takeaway: this is where the SWG quietly earns or loses its keep. Five vendors actually analyze the page a user is loading, which is what catches a phishing site in the minutes before it reaches any reputation feed. Fortinet, Cisco, and Cloudflare block phishing primarily through reputation and ML domain scoring, which is effective but structurally slower against brand-new pages. Note that Fortinet's PARTIAL here is exactly what pulls it into the 90% tier rather than a perfect score, and phishing is the check dragging both Cisco and Cloudflare down to 80%. If credential-phishing is high on your threat model, this line matters more than the SWG headline.
What This Means for Your SASE Evaluation
Stop paying a premium for "SWG"
Every vendor in this comparison delivers enterprise SSL inspection, granular URL filtering, and cloud sandboxing. If a vendor is positioning any of those three as a reason to choose them over a competitor in 2026, they are charging you for table stakes. Treat the base SWG as a solved commodity and negotiate accordingly.
Probe the PARTIAL answers, not the YES answers
The scores cluster because the YES answers are all real. The differences live in the PARTIALs and the licensing footnotes:
- 1."Is browser isolation included, or a separate SKU?" Only Check Point lacks cloud RBI outright, but Zscaler, Netskope, Palo Alto, and Cisco all bill it as an add-on, and even Cato, Fortinet, and Cloudflare gate it behind a premium tier. Get the isolated-traffic caps and per-user pricing in writing.
- 2."Which tier includes the sandbox, and what does it exclude?" Cloudflare skips files over 100 MB and PGP-encrypted files. Zscaler puts patient-zero blocking behind Advanced. Netskope and Cisco tie sandboxing to higher tiers.
- 3."Does phishing detection render the page, or just score the domain?" Five vendors do live-page analysis. Three do not. Ask for a demo against a freshly-registered lookalike domain, not a slide.
- 4."Where does TLS decryption happen and what does it not decrypt?" Every vendor has an exception list. Make them show you.
The uncomfortable truth
No scorecard for a commoditized category should drive your SASE decision on its own. The SWG is one pillar. How it converges with your ZTNA, CASB, DLP, and firewall-as-a-service, all under one policy engine and one console, is where platforms genuinely diverge. Use this comparison to check the box and negotiate the price, then spend your evaluation energy on the categories that are still contested.
The Bottom Line
The Secure Web Gateway has matured into a commodity. All 8 SASE vendors decrypt TLS, filter URLs granularly, and sandbox unknown files. Cato Networks earns its 100% by making browser isolation and real-time phishing analysis part of the integrated platform (RBI at a premium, but integrated), and the 90% cluster of Zscaler, Palo Alto, Netskope, Fortinet, and Check Point is functionally equivalent on the fundamentals. Cloudflare and Cisco land at 80% not because their SWG is weak, but because their phishing detection leans on reputation and, for Cloudflare, sandboxing carries hard exclusions.
The lesson for buyers: stop overpaying for SWG as a differentiator. The basics are settled. Direct your scrutiny at the depth, full versus hedged decryption, native versus add-on isolation, bundled versus tiered sandboxing, and live-page versus reputation-based phishing detection. That is where your money and your risk actually live.
