Builders build. We watch what leaks.

Software ships in a weekend. Every week something new becomes visible that shouldn't be. Open endpoints. Forgotten files. Certificates that telegraph what's coming.

Bolwerk looks at the same public sources an attacker would: certificate transparency logs, DNS, WHOIS. And tells you what's there. So you see it first.

How it works

This is how we think about security.

Public data, your insight

We only monitor what's already public: certificate transparency logs, DNS records, subdomains. No tracking, no profiling.

Proactive, not reactive

You get a warning before it becomes a problem. Not a report after the damage is done.

AI that explains why

When Bolwerk flags something, we show you why. Not just a score, but reasoning you can evaluate.

Simple enough to check

No complex setup, no certifications needed. Something you can check in 30 seconds, like your email.
