Data Breach Monitor & Alert Service

Help individuals and small businesses monitor if their data has been compromised in known breaches. A SaaS tool that checks email addresses/domains against breach databases and sends alerts when new breaches are discovered, similar to Have I Been Pwned but with proactive monitoring and remediation guidance.

Have I Been Pwned offers the core lookup for free, and Troy Hunt has signaled openness to licensing the API, which means the underlying data problem is largely solved — the real wedge here is the SMB workflow layer on top: automated domain-wide monitoring, staff alerts, and step-by-step remediation checklists that a five-person company will actually act on. Cyber insurance requirements and growing regulatory pressure (GDPR, state-level breach notification laws) are pushing SMBs to document their security posture, which creates a legitimate reason to pay for a paper trail beyond a free one-off lookup. The $2k–$10k/mo revenue band is achievable but requires meaningful B2B traction, since individuals won't pay more than a few dollars a month and you'd need thousands of them to hit even the low end. The biggest risk is that identity protection incumbents like 1Password (Watchtower) or antivirus bundles absorb this feature for free, commoditizing the alert layer before you can establish retention.
