# Red Hat Releases RHEL 10.3 Security Features

Red Hat released Enterprise Linux (RHEL) 10.3 with sealed images for Image Mode, post-quantum cryptography features aligned with CNSA 2.0 requirements, and self-managed AI assistance for disconnected environments. The release is a product update, not a solicitation or contract award, but it may affect technology evaluations and deployment planning in government and other regulated environments.

- Agencies and contractors can assess whether sealed images and the post-quantum cryptography features fit their security and deployment needs; alignment with CNSA 2.0 should not be treated as confirmation of compliance.
- Organizations evaluating RHEL 10.3 should review compatibility with existing systems, subscription requirements, and upgrade paths before planning adoption.
- The self-managed AI capability may be relevant to disconnected environments where external connectivity is limited; assess its fit against operational requirements.
