Why Immune
Why ransomware resilience beats detection alone
Hospitals already own security tools, and still get shut down by ransomware. The problem is not a lack of products; it is a gap in what those products are designed to do. Immune exists to close that gap — to keep the hospital running when an attack succeeds, not just to sound an alarm when it starts.
Endpoint tools detect and block on devices that run an agent. Backups restore data on a schedule. Neither keeps a hospital operating through an attack, protects agentless medical devices, or recovers clinical systems in the right order. Immune is built to do all three.
The gap between the tools you have and the outcome you need
Walk into most hospital security programs and you will find capable tools doing capable work. Endpoint detection watches the laptops and servers. Firewalls guard the perimeter. A backup product copies data every night. A monitoring console collects alerts. Each is good at its job. And yet hospitals with all of this still make the news for weeks-long ransomware shutdowns. The uncomfortable truth is that this stack, however well-run, is optimized for the wrong outcome. It is built to detect attacks and to store copies of data. It is not built to keep a hospital running when an attack gets through — and something always eventually gets through.
Immune starts from the outcome hospitals actually need: continuity of care through an attack. That reframing changes what the technology has to do. It is not enough to notice an intrusion; the intrusion has to be stopped from spreading. It is not enough to have backups; the hospital has to be restored quickly, cleanly, and in the right order. And it is not enough to protect the devices that can run an agent; the thousands that cannot must be protected too. Immune is designed around these requirements, which is why it delivers resilience where a conventional stack delivers only visibility.
Why EDR alone falls short against ransomware
Endpoint detection and response is genuinely valuable, and Immune is designed to work alongside it, not against it. But EDR has structural limits that ransomware operators exploit every day. It depends on installing an agent, so it is blind to the medical devices that cannot host one — the very systems attackers increasingly target. It is oriented toward recognizing malicious software, so it struggles against attackers who bring no malware and simply log in with stolen credentials and use legitimate tools. And its job largely ends at detection and blocking; it does not, on its own, bring a shut-down hospital back to working order. Where EDR stops, the hospital's worst hours are just beginning.
Why backups alone aren't recovery
Backups feel like the ultimate safety net, and many hospitals assume they are covered because they have them. Then an attack arrives and the gaps appear. Attackers hunt down and destroy backups early, because they know an organization that cannot recover is one that will pay. Even intact backups are often slow to restore, untested at full scale, and — most damaging of all — restored in the wrong order, so clinical systems come back in a broken, dependency-tangled mess that takes weeks to sort out. Having backups is not the same as having recovery. Recovery is a capability you have to engineer, and it is one Immune builds in.
What Immune adds
The resilience layer your stack is missing
Immune is not a replacement for your firewalls, endpoint tools, or backups. It is the layer that ties defense to outcome — the part that ensures an attack is caught early, contained fast, and recovered from cleanly, across the whole hospital including the systems other tools cannot see.
Keeps the hospital running
Resilience-first design: contain the attack and preserve care, not just detect and alert.

Common questions
Why Immune, answered
+Why isn't EDR enough to stop ransomware?
Endpoint detection and response protects devices that can run its agent and focuses on detecting and blocking malware. It struggles with attackers using valid credentials, and it cannot protect the many medical devices that can't host an agent. It also does not, on its own, restore a hospital to running order after an attack.
+Aren't good backups enough to recover from ransomware?
Backups are essential but insufficient on their own. Attackers target them first, ordinary backups can be slow and unproven to restore, and restoring in the wrong order can take a hospital weeks. Immune adds immutable, verified backups and orchestrated, clinical-order recovery.
+What does Immune add that other tools don't?
Immune unifies detection, containment, and self-healing into one resilience loop, protects agentless medical devices at the network boundary, verifies internal access continuously, and restores clinical systems in the right order — all with patient-safety gating and on-premises deployment.
+Does Immune replace our existing security stack?
No. Immune complements endpoint protection, firewalls, and backups by adding the containment-and-recovery resilience layer they lack and covering the devices they cannot see.
