Halberd Security Labs runs adversary-grade penetration tests and red-team operations for banks, hospitals, and critical infrastructure. Real attackers don't follow a checklist — neither do we.

Exposure estimator

Answer four quick questions to get a directional read on your external attack surface and a suggested engagement type. Runs entirely in your browser — nothing is sent anywhere.

Awaiting input

Adjust the fields and run the estimator to see a directional exposure score.

Directional estimate for planning only — not a security assessment or a guarantee of any kind.


How we work

Findings you can act on the same day.

01

Evidence over theater

Every claim in our reports is backed by reproducible proof — request, response, and the exact steps to fix it.

02

Operate like the adversary

We chain low-severity issues the way a real attacker does. Context, not a checklist, decides what matters.

03

Retest is included

We don't bill twice to confirm a fix. Verification of remediated findings ships with every engagement.

Find it before they do.

Most engagements scope in a single 30-minute call. Tell us what keeps you up at night and we'll propose the smallest test that answers it.
