Security Made Simple

Three steps to complete server protection

1

Connect Digital Ocean

Connect your DigitalOcean servers (or install the agent) and run a read-only scan against a core CIS-aligned Linux baseline. Hardenos records evidence (the exact setting/value) and gives you a posture score.

2

Choose Your Server

Use the Setup Wizard to apply only the safe core controls. Risky changes (SSH/firewall) are guarded with preflight checks, staged rollout, and a clear preview of what will change.

3

Deploy & Monitor

Hardenos continuously re-checks your baseline, alerts on drift (PASS β†’ FAIL), and lets you revert changes instantly using saved restore pointsβ€”so you stay hardened over time.

as long as it's not ai and fast to roll out, and you actually have experience in this that includes cve finding, yes

That's a nice idea, but you need to put more context into it for people to actually appreciate and trust it. Create a website that showcases exactly what you wrote, with some SEO, and it will gain more followers.

I'd be interested, but might not actually use it or use a subset of it. Would be nice to see what you do differently.

Does DO not already have hardened containers? If not I would suspect they will come soon. That would be pretty cool, as well as monitoring for it.
