AI Security Buying Guide: How to Evaluate Vendors Against the 2026 Compliance Stack
The AI security vendor landscape in 2026 splits across model-side guardrails, browser extensions, CASB integrations, ML observability, and identity-aware proxies. Each category solves a different problem and produces different evidence. This buying guide walks through the ten questions a CISO or compliance lead should ask any AI security vendor before purchase. The questions reflect the EU AI Act, NIST AI RMF, ISO 42001, and sector frameworks the buyer is buying against. The aim is an architectural fit decision, not a feature-checklist comparison.
