Free Cyber Exposure Check

A quick, free, passive look at one domain, without an account.

The Free Cyber Exposure Check on public.sentinel-rsoc.com gives anyone a short summary of a single domain's external exposure, with no sign-up.

What it does

• Checks one domain, passively (DNS, TLS and HTTP observations only), with no active testing.
• Shows the number of observations, up to five of the most important findings with severity, confidence and a short rationale, and the limitations of the check.

What it doesn't do

• It doesn't show raw evidence, store anything in an account, or monitor over time.
• Results and evidence are deleted automatically after one hour.
• To protect the service, the number of checks per visitor is limited.
