## Bio

Profile built from public OpenID Foundation and company records.

## Where their work shows up

Federation has a structural flaw: a token is issued for an hour, and nothing in the protocol revokes it if the user is fired, the device is compromised, or the session is hijacked in minute two. CAEP and the Shared Signals Framework let an identity provider and a relying party exchange those events in near real time, which is what makes [Zero Trust](https://startwithidentity.com/guides/fundamentals/what-is-zero-trust/) continuous rather than a check at the door. See the [ITDR guides](https://startwithidentity.com/guides/security/) and the [best ITDR tools](https://startwithidentity.com/rankings/best-itdr-tools/) ranking for the detection side of the same problem.
