I'm curious about what Docker charges for their hardened images, known as Docker Hardened Images (DHI). I've heard of Chainguard, but I'm looking for other alternatives. Any insights would be appreciated!

When I checked in on pricing at launch, they mentioned around $25K annually for each hardened image, but it seemed like they were still figuring things out after that initial quote. No further updates on pricing yet!

VulnExpert: We're currently paying $800 per image each month at VulnFree, and theyโ€™re the only company providing custom images.

For alternatives to hardened images, I think Echo is a great option among newer ones out there.

Just to clarify, we're at $800 per image per month at VulnFree, which is notable since they're offering the only custom images in the market right now.

SkepticalObserver: Just a heads up on this one: since you work at VulnFree, take this info with a grain of salt if you're reading this in the future; it feels a bit promotional.
