# Akamai Explains CISA Zero Trust Model

Akamai and Carahsoft sponsor an e-book discussing CISA’s five-pillar zero trust model, the risks of technology silos, and a least-permissive trust approach. The material provides cybersecurity contractors with context on federal zero trust concepts, but it does not announce a solicitation, contract award, funding, or other procurement action.

- Contractors may use the e-book to understand concepts relevant to federal zero trust discussions, while accounting for its vendor sponsorship.
- No specific agency requirement, procurement timeline, contract opportunity, or funding commitment is identified.
