ISO 27001 vs HIPAA: How They Differ
ISO 27001 is a voluntary, internationally recognized certification for your overall security management system. HIPAA is a mandatory US law that applies specifically to protected health information (PHI) and has no certificate. A healthcare vendor selling globally may need ISO 27001 for international buyers and HIPAA to operate legally in US healthcare.

How Much They Overlap
ISO 27001 vs HIPAA FAQ
What is the difference between ISO 27001 and HIPAA?
ISO 27001 is a voluntary international certification covering your entire information security management system, proven with a public certificate. HIPAA is a mandatory US law focused specifically on protected health information, with no certificate — you demonstrate compliance through a risk assessment and documented controls. One is a credential; the other is a legal obligation.
Does ISO 27001 cover HIPAA requirements?
Partly. ISO 27001's controls overlap heavily with HIPAA's Security Rule technical safeguards, so an ISO-certified organization has implemented much of what HIPAA requires. However, HIPAA also includes Privacy and Breach Notification rules plus Business Associate Agreement obligations that ISO 27001 alone does not satisfy.
Is ISO 27001 or HIPAA more expensive?
ISO 27001 typically costs more upfront because it's a formal certification — Stage 1 and Stage 2 audits run about $14,000–$50,000 for SMBs plus annual surveillance. A HIPAA risk assessment or audit runs $2,000–$50,000, though remediation and an optional HITRUST certification can raise the total.
Do I need both ISO 27001 and HIPAA?
If you're a healthcare technology vendor selling internationally, often yes: ISO 27001 gives international customers a recognized certificate, while HIPAA compliance is legally required to handle PHI in the US. Their overlapping controls make running both more efficient than tackling each in isolation.
