Industry
Clinical uptime and patient-data confidentiality, with the availability discipline that diagnostic and record systems require.
The context
Healthcare IT carries a combination few other sectors face: patient data that must stay confidential, and clinical systems that must stay available because a consultation is happening now and cannot wait for a restore.
So the design is availability-first and confidentiality-throughout. Redundancy on the systems clinicians touch, encryption and access control on records, audit trails on who viewed what, and backups tested by restoring — because a hospital information system down for a day is a clinical incident, not an IT ticket.
The constraints
Generic IT advice fails here for specific reasons. These are the ones that change the design.
HIS, LIS and PACS availability is a patient-care issue. Recovery time objectives are measured in minutes.
Records require encryption, strict access control and an audit trail of access — and increasingly, demonstrable compliance.
Diagnostic equipment often runs embedded, unsupported software that cannot be patched but must reach the network.
There is no quiet window in a facility that runs continuously. Maintenance must be non-disruptive by design.
Wards, OPD, labs, pharmacy and reception all need reliable access, frequently on wheeled and mobile devices.
Our approach
Specific design decisions, not principles. This is what actually changes in a deployment for this sector.
Redundant power, network paths and storage for HIS, LIS and PACS, with failover tested rather than assumed.
Role-based access to patient records with logging of who viewed what and when, retained per policy.
Diagnostic equipment on its own VLAN with tightly controlled routes, protecting devices that cannot be patched.
Rolling maintenance designed so no clinical service is interrupted, coordinated with ward and OT schedules.
Wi-Fi engineered for roaming across a large floor plate, so a cart moving between wards does not lose its session.
A typical engagement
Diagnostic equipment shared a flat network with administrative PCs and guest Wi-Fi, and the HIS backup had never been restore-tested. We segmented the network around clinical priority, isolated the medical devices, and proved the restore worked — which it did, at eleven hours, against an expectation of two.
Client details are withheld deliberately. We do not publish client names or site specifics without written permission — particularly for security work, where publishing what we installed and where would be indefensible.
Full capability
Most clients in this sector start with the pillars above and add others as the estate consolidates.
