Ransomware protection built for healthcare
Healthcare is the most consequential ransomware target in the world, because in a hospital, downtime is a patient-safety problem, not just an IT one. Immune keeps hospitals running through an attack — detecting in seconds, containing before spread, and self-healing clinical systems from immutable backups — including the connected medical devices other tools can't protect.
Immune is engineered for the clinical reality of healthcare: care-aware automation that never overrides a clinician on the actions that matter, and agentless coverage for the devices that keep patients alive.
Why ransomware hits healthcare hardest
No sector feels ransomware like healthcare. When an attack lands, ambulances divert, surgeries cancel, and clinicians revert to paper — and every minute of downtime carries real risk to patients. Attacks on Change Healthcare, CommonSpirit, Ascension, and the NHS have shown that a ransomware incident in healthcare is a patient-safety event with national consequences.
Hospitals also run the hardest environment in security: tens of thousands of connected medical devices that can't run a security agent, legacy clinical systems that can't be patched, and a duty of care that means you can't simply shut everything down to contain a threat. Immune is built for exactly this reality — protecting agentless devices at the network boundary and gating any care-impacting action behind human approval.
Our solution
How Immune protects hospitals
Immune's detect, contain, and self-heal platform, tailored to the realities of healthcare.
Agentless device protection
Defends connected medical devices and legacy systems at the network boundary, without an agent.
Care-aware containment
Isolates threats in seconds while gating patient-impacting actions behind one-click human approval.
Clinical-order recovery
Self-heals from immutable backups in clinical priority — identity, network, EHR, then ancillary systems.
EHR & imaging protection
Protects the electronic health record and PACS, and restores them first if affected.
Behavioral detection
Catches ransomware by behavior — including zero-day strains with no signature.
HIPAA-aligned controls
Encryption, immutable audit, and access controls that map to healthcare safeguards.
Use cases
Where Immune protects hospitals
Active ransomware attack
Contain the spread and keep clinical systems running while the attack is shut down.
Medical-device intrusion
Detect and quarantine threats on connected devices without disrupting patient care.
Backup-targeting attack
Immutable recovery points survive an attacker's attempt to destroy the escape route.
Double-extortion attempt
Detect exfiltration in progress and recover cleanly, removing the attacker's leverage.

Common questions
Ransomware protection for healthcare, answered
+How is Immune different from EDR for hospitals?
Endpoint detection tools protect managed computers but can't run on the connected medical devices attackers target most, and they focus on detection rather than keeping care running. Immune adds agentless device coverage, care-aware containment, and self-healing recovery — the resilience layer that keeps a hospital operating through an attack.
+Can Immune protect medical devices that can't run an agent?
Yes. Immune protects connected medical devices and legacy clinical systems at the network level, detecting and quarantining threats without needing to install anything on the device itself.
+Does Immune's automated response risk patient safety?
No. Immune is designed so that any action that could affect patient care is gated behind one-click human approval, while low-risk containment happens automatically. Response never overrides clinical judgment on the actions that matter.
