Frequently Asked Questions

Which SASE vendor is best for casb & shadow it discovery?
Based on 5 checks across 8 vendors, Check Point and Cisco and Netskope lead with 5 out of 5 capabilities fully supported (YES). Cloudflare scored lowest with 3 YES answers. Results are based on publicly available documentation. Always verify with the vendor before purchasing.
Does the platform provide a catalog of 10,000+ pre-classified cloud apps with risk ratings and categories?
Check Point, Cisco, Netskope fully support this. Cato Networks, Fortinet, Palo Alto Networks, Zscaler offer partial support. Cloudflare does not support this. The broader the catalog, the fewer unknown apps slip through. Vendors with thin catalogs miss niche and regional SaaS tools
Can it assign risk scores to discovered shadow IT apps and block access based on risk thresholds?
Cato Networks, Check Point, Cisco, Fortinet, Netskope, Palo Alto Networks, Zscaler fully support this. Cloudflare offers partial support. Not all shadow IT is equal. A file-sharing app with no encryption is higher risk than an internal wiki tool
Can it detect and control OAuth token grants and third-party SaaS-to-SaaS integrations?
Check Point, Cisco, Cloudflare, Netskope, Palo Alto Networks, Zscaler fully support this. Cato Networks, Fortinet offer partial support. Users grant OAuth access to random apps that then have persistent access to corporate data. This is one of the fastest-growing attack vectors
Does the platform automatically discover unsanctioned SaaS applications across all users without manual configuration?
Cato Networks, Check Point, Cisco, Cloudflare, Fortinet, Netskope, Palo Alto Networks, Zscaler fully support this. You can't secure what you can't see. If shadow IT discovery requires manual app lists, it's already outdated
Does the CASB support both inline (real-time proxy) and API-based (out-of-band) modes for SaaS control?
Cato Networks, Check Point, Cisco, Cloudflare, Fortinet, Netskope, Palo Alto Networks, Zscaler fully support this. Inline catches threats in real time. API mode covers sanctioned apps with deep inspection. You need both for complete coverage
How is the CASB & Shadow IT Discovery comparison tested?
We test 5 specific scenarios across Cato Networks, Check Point, Cisco, Cloudflare, Fortinet, Netskope, Palo Alto 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.
