Independent evaluation frameworks for this category.

API Security Platforms
The API is now the primary attack surface, and a WAF pointed at it isn't API security. Evaluate Salt, Akamai (Noname), Imperva, F5, Traceable, Wallarm, Cequence, and Data Theorem on whether they actually discover your shadow APIs and catch BOLA and business-logic abuse at runtime — not just sign endpoints off as “protected.”
Attack Surface Management (ASM / CTEM)
Evaluate Wiz, CrowdStrike Falcon Surface, Microsoft Defender EASM, Cortex Xpanse, Censys, CyCognito, Tenable, and runZero across EASM, CAASM, and platform-embedded camps — judged on discovery accuracy and how cleanly the surface feeds prioritization, not how many assets it claims to find.
Cloud Access Security Broker (CASB)
Evaluate Netskope, Microsoft Defender for Cloud Apps, Zscaler, and Palo Alto for SaaS security, shadow IT discovery, and data protection.
