I'm looking for information on what Docker charges for their hardened images, known as Docker Hardened Images (DHI). Also, I'd love to hear about any alternatives out there, particularly to Chainguard.

When I last spoke to Docker about their hardened images, they mentioned they were still figuring out the pricing. They quoted me around $25K per year for each hardened image, and that's pretty much where our conversation ended.
For alternatives to Chainguard, I've heard that Echo is actually one of the best newer options available right now.

Just so you know, we're paying about $800 per image per month at VulnFree, and they’re the only ones that provide custom images.
