Immune vs. EDR vs. backup: how the approaches compare
No hospital should choose its ransomware strategy on marketing claims. This is an honest look at what endpoint detection, backup-only recovery, and a resilience platform each do well, where each falls short, and why the strongest programs combine them with Immune at the center.
Endpoint tools excel at detecting malware on managed devices. Backups can restore data. Immune adds what neither provides: containment, clinical-order self-healing, agentless device protection, and continuity through an attack — designed to work alongside both.
Three approaches, three different jobs
It is tempting to treat ransomware defense as a single purchase, but the tools hospitals rely on were built for genuinely different jobs, and understanding those differences is the key to a sound strategy. Endpoint detection and response was built to find and stop malicious software on the computers it can monitor. Backup and recovery products were built to make copies of data so it can be restored after loss. A resilience platform like Immune was built to keep an organization operating through an attack and to recover it cleanly afterward. These are complementary jobs, not competing ones — but a hospital that owns only the first two has real gaps, and those gaps are exactly where ransomware does its damage.
The honest way to compare them is not to declare a single winner but to map each approach against the full set of things a hospital actually needs, and to see clearly where each one helps and where it leaves the hospital exposed. The table below does that, and the sections that follow explain the most important gaps.
| Capability | Endpoint (EDR) | Backup only | Immune |
|---|---|---|---|
| Detect known malware | Strong | No | Strong |
| Catch valid-credential / living-off-the-land attacks | Limited | No | Strong |
| Protect agentless medical devices (IoMT) | No | No | Yes — at the boundary |
| Deception / canary early warning | Rare | No | First-class |
| Automatic containment of spread | Partial | No | Yes, patient-safety gated |
| Recovery without paying ransom | No | Sometimes | Yes — immutable, verified |
| Clinical-order restoration | No | No | Yes |
| Keep hospital running during attack | No | No | Yes — continuity mode |
| Fully on-premises / data sovereign | Often cloud | Varies | Yes |

The gaps that matter most
Where endpoint and backup approaches leave a hospital exposed
Three gaps show up again and again in real hospital ransomware incidents, and they are the gaps Immune was built to close. The first is the agentless medical device. Endpoint tools cannot protect what they cannot install on, and backups do nothing to stop a device from being used as an attack path. In a hospital with thousands of connected devices, this is not a small blind spot; it is often the way the attacker gets in and moves. Immune protects these devices at the network boundary, which is the only place they can be defended.
The second gap is the valid-credential attack. When an intruder logs in with stolen credentials and uses legitimate administrative tools, there is no malware for an endpoint tool to catch and nothing for a backup to prevent. Immune's continuous access verification catches this by watching behavior rather than signatures. The third gap is recovery itself. Backups are copies, not a recovery capability; without immutability they can be destroyed, and without clinical-order orchestration they can take weeks to restore correctly. Immune turns backups into fast, validated, clinically-ordered recovery — and, crucially, it stops the attack before that recovery is even needed.
The bottom line
- Keep your EDR and backups. They do real work and Immune complements them.
- Add the resilience layer. Containment and self-healing are what keep a hospital running.
- Close the device gap. Only network-boundary protection covers agentless medical devices.
- Make recovery real. Immutable, verified, clinical-order restore beats a folder of backups.

Common questions
Comparing ransomware approaches, answered
+What is the best ransomware protection for healthcare?
The best protection combines prevention, detection, containment, and validated recovery, and it covers the medical devices that cannot run an agent. Endpoint tools and backups each cover part of this; Immune is designed to unify the full lifecycle with a resilience-first, healthcare-specific approach.
+How does Immune compare to endpoint detection and response?
EDR is strong at detecting and blocking threats on managed devices. Immune complements it by adding automatic containment and self-healing recovery, protecting agentless medical devices, and catching valid-credential attacks — closing gaps EDR leaves open.
+How does Immune compare to a backup product?
Backup products focus on copying and restoring data. Immune adds immutable, attacker-proof recovery points, verifies them clean and pre-attack, and orchestrates recovery in clinical dependency order — and it stops the attack in the first place rather than only helping afterward.
+Should we replace our existing tools with Immune?
No. Immune is designed to work alongside your existing prevention, detection, and backup investments, adding the resilience layer and the device coverage they lack.
