⁠What is a hardened image?

A hardened container image is a functionally equivalent copy of a container image that has been optimized by removing unnecessary software components, significantly reducing its software attack surface and improving its security. Removing unnecessary software components is a critical practice to protect your infrastructure from attacks and limiting the blast radius of any attacks.

This image is a hardened version of the official Platform One Postfix IronBank⁠ image on Docker Hub.

Vulnerability reports for RapidFort's hardened images are updated daily to include newly discovered vulnerabilities and fixes.

⁠What’s the difference between the official Platform One Postfix IronBank⁠ image and this hardened image?

RapidFort’s hardened rapidfort/postfix-ib⁠ image has been optimized by RapidFort's SASM platform and is functionally equivalent to the original image.

We are big fans of open-source software and secure software development. RapidFort's community images are our way of giving back to the community and helping reduce the burden on security and development teams.
