Curity looks to reinvent IAM with runtime authorization for AI agents
Multiple approaches to agent security: Today, agent security falls into one of several camps, which include increasingly inadequate inline approaches such as API gateways and web application firewalls (WAFs), and out-of-band analysis systems that infer intent by analyzing agent behavior against a baseline.Curity’s Access Intelligence, by contrast, is a self-hosted microservice that acts as a…
