When Healthcare Organizations Call Us

No internal CISO and leadership is feeling the security gap

Preparing for a HIPAA audit, OCR investigation, or regulatory review

HITRUST certification is a business, investor, or partner requirement

Cyber insurance renewal requiring demonstrated security maturity

Investor or enterprise partner due diligence requiring evidence of a security program

Grant funding or federal program participation requiring security documentation

Deploying AI tools in clinical or operational workflows and needing governance before OCR asks questions

Staff using consumer AI tools with patient data and leadership needing a shadow AI policy

Vulnerability scans, penetration testing, or technical assessments required by an insurer, assessor, or regulator — and needing a program that coordinates and interprets those results
