Breach Exposure Check

What does the criminal ecosystem already know about your organization? A look at your exposure in breach data — and what to do about it.

Request a scoping call Our methodology
Why this matters: Your employees’ credentials are already circulating in breach lists and infostealer logs — that is how the Snowflake-era attacks worked: no hacking, just logging in with what was already on sale. We documented the combo-list economy in depth on this site; this service points that same lens at your organization.

What we cover

  • Corporate email domains searched across known breach corpora
  • Credential exposure: reused and plaintext passwords
  • Infostealer log indicators for your domain
  • Executive and high-privilege account exposure
  • Third-party and SSO account overlap
  • Prioritized lock-down plan per finding

How we test

1Scope

We agree the domains and key identities in scope.

2Exposure search

Your domains searched across breach data sets and stealer-log indicators — research performed from published corpus analysis.

3Risk analysis

Which exposures actually matter: privileged users, password reuse patterns, MFA coverage gaps.

4Lock-down plan

Forced resets, MFA upgrades, and monitoring recommendations, sequenced by risk.

What you get

  • Exposure report per domain and identity
  • Risk-ranked credential findings
  • Sequenced lock-down plan
  • Optional re-check cadence

Common questions

Where does this data come from?

From publicly circulating breach corpora and published security research — the same data criminal buyers see. We analyze exposure; we do not purchase stolen data.

Are individual employees named?

Findings focus on accounts and risk patterns. Where individuals appear (e.g., reused passwords), results go to security leadership for handling — the goal is remediation, not blame.

How often should we re-check?

Quarterly, or immediately after any major breach makes the news — new corpora appear constantly.

Authorization first, always. Testing happens only with your written permission and agreed rules of engagement — the same ethics that govern responsible disclosure on this site.
