Ransomware protection for Cheshire's hospitals, NHS trusts, and life sciences

Most Cheshire providers already run a firewall, an endpoint tool, a backup product, and a monitoring console. Ransomware still gets through the seams between them, which is where the attackers who hit the North West trusts in late 2024 operated. We are not a fourteenth console. We are one platform that owns the whole lifecycle of an incident: seeing it, understanding it, stopping it, and undoing the damage.

For a Cheshire trust or a life-sciences firm, that means network, host, identity, and deception signals are correlated into a single picture. A living-off-the-land intrusion that would evade any one sensor still surfaces, because we watch the relationships between events, not just the events on their own.

We do not wait for a known signature. We fuse four kinds of signal. Behavioral monitoring watches for the lateral movement and reconnaissance that precede encryption. Deception plants decoy files where no legitimate workflow will touch them, so the instant an intruder does, we get a high-confidence signal within about two seconds. Endpoint telemetry catches the sharp spike in file-change entropy when bulk encryption begins. And continuous access scoring flags a credential behaving unlike itself, the valid-login path that signature tools wave through.

This matters for Cheshire because the attacks that hit the region were double extortion, stealing data before encrypting it. The group that claimed the Alder Hey incident said it held records going back years. Our network-level detection is tuned to surface the large, abnormal outbound transfers that signal exfiltration in progress, so the aim is to catch the theft while it happens, not after it is on a leak site.

A Cheshire acute trust runs thousands of connected medical devices, from infusion pumps and patient monitors to imaging controllers and lab analyzers. Most cannot run an endpoint agent, so a conventional EDR tool is blind to the majority of the real attack surface, and attackers target exactly that gap. We protect those devices at the network boundary and, on a confirmed threat, quarantine a compromised device at the network layer rather than shutting it down in a way that interrupts care. For a district general hospital running at capacity, that distinction is the line between a security action and a patient-safety event.

When a verdict is confident and the action is safe, we act on our own: block the malicious source, revoke the compromised session and credentials, and microsegment the affected host or segment so the attacker cannot move sideways across a hospital or a regional network. We aim to do this within about thirty seconds, the window where an attack is still a contained incident rather than a week-long major incident like the one next door in Wirral. Anything that could affect patient care waits for one-click human approval, with the source already blocked in the meantime.

Recovery is a first-class outcome, not an afterthought. We keep verified, immutable, air-gapped backups that ransomware cannot alter or delete, because attackers go for ordinary backups first. When it is time to restore, we confirm a backup predates the attack, check it is clean, and bring systems back in dependency order: identity and network, then EHR and PAS, then pathology, imaging, and pharmacy. That is what turns a double-extortion crisis into a controlled recovery, and it removes the leverage that makes paying a ransom tempting.

Cheshire NHS organizations and life-sciences firms hold data they cannot risk handing to a third party or moving offshore. Immune can run as a managed service, in a hybrid model, or entirely on-premises and air-gapped, including the analysis engine. For a Cheshire trust or research firm, that means ransomware resilience without moving patient data or intellectual property outside the UK, and every detection, decision, and recovery step is written to a tamper-proof, hash-chained audit log that supports your NHS DSPT, UK GDPR, and ICO obligations.
