Attack surface management for healthcare
Patient portals, acquired brands, and forgotten subdomains quietly widen your internet-facing footprint, and every one of them can expose protected health information. Resensor maps it all continuously and ranks what is exploitable with CISA KEV and FIRST EPSS, so you fix the exposures that matter before an attacker finds them.
Healthcare attack surfaces grow faster than anyone can track
Care delivery and health-tech run on a sprawl of internet-facing systems, and the riskiest assets are usually the ones nobody is watching.
Portals and APIs everywhere
Patient portals, scheduling, billing, and partner APIs each add public endpoints. A single expired certificate or exposed service on one of them is a path to PHI.
Mergers leave orphaned brands
Acquisitions bring domains and subdomains that never make it onto anyone's inventory. Attackers find those forgotten assets long before your team does.
Patients are easy to impersonate
If your domain can be spoofed or typosquatted, criminals send convincing emails to patients and staff. Health brands are a favorite phishing lure.
The stakes are regulatory
A PHI breach means HIPAA exposure, breach notification, and reputational damage. You are accountable for systems you may not even know are exposed.
What Resensor watches for healthcare
- Patient portals and subdomains across every brand and facility
- Expiring or weak TLS certificates on public-facing systems TLS
- Unexpected exposed services and ports on the perimeter
- Email spoofability across SPF, DKIM, and DMARC DMARC
- Typosquatted look-alike domains targeting patients and staff LOOKALIKE
- Known-exploited vulnerabilities from CISA KEV and high-EPSS CVEs KEV EPSS
- Staff credentials surfaced in known breach data BREACH
- Assets from acquired brands discovered automatically
Evidence for your HIPAA security program
The HIPAA Security Rule expects an accurate, ongoing risk analysis of the systems that handle electronic PHI, and you cannot assess what you have not inventoried. Resensor keeps a current map of your internet-facing systems and their exposures to feed that analysis, and every finding maps to SOC 2, ISO 27001:2022, and PCI DSS v4.0 controls, so a scan turns into audit-ready evidence rather than another spreadsheet.

What is attack surface management for healthcare?
It is the continuous discovery and monitoring of every internet-facing system a healthcare or health-tech organization runs, including patient portals, subdomains, APIs, and certificates, so you can find and fix the exposures that could put protected health information at risk before an attacker reaches them.
How does attack surface management support HIPAA compliance?
The HIPAA Security Rule requires an accurate, ongoing risk analysis of the systems that handle electronic PHI. You cannot assess what you have not inventoried. External attack surface management keeps a current map of your internet-facing systems and their exposures, which feeds that risk analysis. Resensor findings also map to SOC 2, ISO 27001:2022, and PCI DSS v4.0 controls that underpin a healthcare security program.
What external exposures put patient data at risk?
Forgotten patient portals and subdomains, expired or weak TLS certificates, unexpected exposed services, spoofable email domains used to phish patients and staff, typosquatted look-alike domains, and staff credentials surfaced in known breaches.
Can Resensor monitor multiple facilities or acquired brands?
Yes. Resensor discovers the subdomains and assets tied to each domain, including brands picked up through mergers and acquisitions, and scopes them per organization so a multi-site or multi-brand estate stays organized.
