Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed June 20, 2026 ## Definition Health-ISAC (Health Information Sharing and Analysis Center) is a global, nonprofit, member-driven organization that serves as the trusted threat intelligence sharing community for healthcare and public health (HPH) sector members, hospitals, payers, pharmaceutical manufacturers, biotech, and medical device manufacturers. H-ISAC operates a Threat Operations Center (TOC), runs the Medical Device Security Information Sharing Council (MDSISC), publishes the Annual Threat Report, hosts a Member Exchange of indicators of compromise (IoCs) in STIX/TAXII, and coordinates incident response across members during active campaigns. What the regulation says FDA's premarket and post-market cybersecurity guidance encourages manufacturers to participate in Information Sharing and Analysis Organizations (ISAOs), H-ISAC is the recognized ISAO for the HPH sector and is referenced in the [HSCC Joint Security Plan](/terms/hscc-jsp). ## What this means in practice For medical device manufacturers, H-ISAC membership and MDSISC participation are increasingly expected, both by hospital customers (who want their vendors plugged into sector intel) and by FDA, which references 'participation in an ISAO' as evidence of a mature post-market cybersecurity program. The Medical Device Vulnerability Information Sharing initiative coordinates [coordinated vulnerability disclosure](/terms/cvd) across the membership. Common pitfalls - • Joining for branding rather than operationally consuming and contributing intel, the value is in the bidirectional flow. - • Confusing H-ISAC with HSCC, HSCC is the Health Sector Coordinating Council (policy/standards), H-ISAC is operational threat sharing. - • Assuming H-ISAC replaces internal CVD, coordinated disclosure with H-ISAC accelerates sector-wide notification but doesn't substitute for your own program. ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Cybersecurity Coordinated Vulnerability Disclosure(CVD) A documented process for receiving, triaging, and responsibly disclosing security vulnerabilities reported by external researchers. ](/terms/cvd)[ Cybersecurity HSCC Joint Security Plan(HSCC JSP) An industry-developed reference framework from the Healthcare Sector Coordinating Council for end-to-end MedTech cybersecurity. ](/terms/hscc-jsp)[ Cybersecurity ICS Medical Advisory(ICSMA) CISA's official vulnerability advisories for medical devices, the public record of disclosed device cybersecurity issues, indexed as ICSMA-YY-DDD-NN. ](/terms/ics-medical-advisory)[ Cybersecurity Premarket Cybersecurity Submission The bundle of cybersecurity artifacts a sponsor includes in a 510(k), De Novo, PMA, or HDE submission for a cyber device. ](/terms/premarket-cybersecurity) ### More in Cybersecurity · Same category [ Cybersecurity AAMI SW96 AAMI/ANSI standard establishing requirements for medical-device cybersecurity activities throughout the lifecycle. ](/terms/aami-sw96)[ Cybersecurity AAMI TIR57 AAMI Technical Information Report providing MedTech-specific guidance on cybersecurity risk management. ](/terms/aami-tir57)[ Cybersecurity AAMI TIR97(TIR97) AAMI Technical Information Report on post-market security risk management for medical device manufacturers, the operational companion to TIR57. ](/terms/aami-tir97)[ Cybersecurity Brainjacking Unauthorized remote control of an implanted neurostimulator (e.g., DBS) to alter stimulation parameters and harm a patient. ](/terms/brainjacking) Cited by Where this term appears across MedTech Terms.
