Does your SASE vendor actually stop malware and phishing?

SASE vendors all claim advanced threat prevention. We tested 12 specific scenarios - from inline malware blocking to zero-day sandboxing - across 8 vendors to find who actually delivers.

Frequently Asked Questions

Which SASE vendor is best for threat prevention?
Based on 12 checks across 9 vendors, Cato Networks and Netskope and Palo Alto Networks and Zscaler lead with 12 of 12 researched capabilities fully supported (YES). Cloudflare scored lowest with 9 YES answers. Results are based on publicly available documentation. Always verify with the vendor before purchasing.
Does the platform include IPS signatures to detect and block exploit attempts, C2 callbacks, and known attack patterns?
Cato Networks, Check Point, Cisco, Fortinet, Netskope, Palo Alto Networks, Versa Networks, Zscaler fully support this. Cloudflare offers partial support. IPS catches lateral movement, exploit kits, and C2 traffic that AV alone misses
Does the platform detect and block phishing URLs in real-time, including newly registered domains and typosquatting?
Cato Networks, Check Point, Netskope, Palo Alto Networks, Zscaler fully support this. Cisco, Cloudflare, Fortinet, Versa Networks offer partial support. Phishing is the #1 initial access vector. If the SWG can't catch credential harvesting pages, users will get phished
Can risky or uncategorized websites be automatically rendered in a remote browser to prevent drive-by downloads?
Cato Networks, Cisco, Cloudflare, Fortinet, Netskope, Palo Alto Networks, Versa Networks, Zscaler fully support this. Check Point offers partial support. Zero-day exploits via drive-by downloads bypass AV. Browser isolation eliminates the risk entirely
Does the platform integrate with XDR/EDR solutions to correlate network-level and endpoint-level threat signals?
Cato Networks, Check Point, Cisco, Fortinet, Netskope, Palo Alto Networks, Versa Networks, Zscaler fully support this. Cloudflare offers partial support. SASE sees network threats, EDR sees endpoint threats. Together they catch what neither sees alone
Does the platform scan file downloads and uploads inline for known malware using signature-based and heuristic engines?
Cato Networks, Check Point, Cisco, Cloudflare, Fortinet, Netskope, Palo Alto Networks, Versa Networks, Zscaler fully support this. Basic but essential - if the SASE can't catch known malware inline, everything else is theater
How is the Threat Prevention comparison tested?
We test 12 specific scenarios across Cato Networks, Check Point, Cisco, Cloudflare, Fortinet, Netskope, Palo Alto Networks, Versa Networks, Zscaler. All answers are sourced from publicly available vendor documentation, knowledge base articles, and verified user reports. YES means confirmed working with documentation, PARTIAL means it works with significant limitations, NO means confirmed not supported.

Methodology

All answers are sourced from publicly available vendor documentation, knowledge base articles, press releases, and verified user reports. We do not rely on vendor marketing claims.

YES means the feature is confirmed working with documentation. PARTIAL means it works with significant caveats or limitations. NO means it is confirmed not supported. TBD means research is still in progress.
