Hospitals run some of the most complex networks in any sector. Electronic health records, imaging systems, connected infusion pumps, building management systems and thousands of staff devices all share the same infrastructure. When ransomware hits, the consequences go beyond data loss. Surgeries get cancelled. Emergency departments close. Patients are transferred to other facilities.
A Secure Access Service Edge (SASE) architecture addresses this complexity by unifying network security and connectivity in a single cloud-managed platform. For healthcare organisations managing multiple sites, mixed IT and medical device environments, and strict regulatory obligations under NIS2 and GDPR, SASE provides a path to stronger security without the operational overhead of managing dozens of separate tools.
This guide covers the specific security challenges hospitals face, how SASE components map to those challenges, and what a phased rollout looks like for a healthcare IT team with limited resources.
How does SASE protect hospital networks?
SASE protects hospital networks by combining identity-based access, web security, site-to-site connectivity and device isolation into one policy framework. Clinicians access only the applications their role requires. Medical devices communicate only with approved systems. Web traffic is filtered and inspected centrally. All of this is managed from a single console with unified logging for NIS2 compliance.
Why hospitals are high-value targets
The healthcare sector reported more significant cybersecurity incidents than any other critical sector in the EU in 2023, with 309 incidents logged by EU member states. According to ENISA’s threat landscape analysis, 54% of those attacks involved ransomware. Hospitals bore the brunt, accounting for 53% of incidents affecting healthcare providers.
Three factors make hospitals particularly vulnerable.
First, the attack surface is enormous. A mid-sized hospital connects thousands of endpoints: workstations, tablets, IP phones, MRI and CT scanners, infusion pumps, HVAC controllers, security cameras and badge readers. Many of these devices run legacy operating systems and cannot be patched or updated without vendor involvement.
Second, availability is non-negotiable. Unlike a consultancy firm that can work offline for a day, a hospital cannot defer care. Attackers know this, which is why healthcare remains a preferred target for ransomware operators seeking fast payment.
Third, the data is extraordinarily sensitive. Patient records combine personal identity data, financial information and medical history. Under GDPR, this qualifies as special category data with the highest protection requirements. A breach triggers mandatory notification obligations and can result in significant fines.
The AZ Monica ransomware attack in January 2026 demonstrated what happens when these factors converge. Over 70 surgeries were cancelled, critically ill patients were evacuated, and emergency services shut down across two campuses. The root cause was lateral movement through a flat network after initial compromise.
The five security challenges SASE solves for healthcare
Broad VPN access that ignores clinical roles
Many hospitals still use VPNs for remote access. A radiologist connecting from home receives the same network tunnel as an administrative assistant. Both can potentially reach systems far beyond their role. SASE replaces this with Zero Trust Network Access (ZTNA), where each user authenticates, their device posture is checked, and they receive access only to the specific applications their role requires. A clinician reaches the EHR and imaging viewer. A finance team member reaches the billing system. Neither can see the other’s applications.
Medical devices that cannot run security agents
Connected medical equipment is one of the hardest problems in healthcare security. MRI scanners, infusion pumps, patient monitors and laboratory instruments run specialised operating systems. Installing a security agent is either impossible or would void the manufacturer’s certification. SASE platforms that include inline isolation hardware, such as NIAC appliances, place these devices behind a controlled gateway. Each device or device class is allowed to communicate only with specific upstream systems: the PACS server, the device management platform, the update server. Everything else is blocked. If ransomware compromises the administrative network, it cannot reach imaging equipment behind the isolation boundary.
Multi-site complexity with limited IT staff
Hospital groups, regional care networks and multi-campus institutions manage security across dozens of locations. Each site has its own mix of devices, connectivity and local requirements. SD-WAN within a SASE framework connects these sites securely over standard internet links, routing traffic intelligently based on application priority. A teleradiology session gets bandwidth priority over a background backup job. New sites or temporary care facilities can be connected in hours rather than weeks.
Fragmented security tools and policy drift
A typical hospital security stack includes separate products for firewalls, VPN, web filtering, endpoint protection and network segmentation. Each tool has its own console, its own policy syntax and its own log format. When a security incident occurs, correlating events across five different dashboards takes hours. A single management console that unifies ZTNA, Secure Web Gateway, Firewall-as-a-Service and SD-WAN eliminates this fragmentation. One policy engine. One log stream. One place to investigate incidents.
NIS2 compliance documentation
Hospitals in Belgium and across the EU are classified as essential entities under NIS2, subject to the strictest obligations including proactive audits, mandatory incident reporting within 24 hours, and personal liability for board members who fail to oversee security measures. The NIS2 compliance checklist details what auditors expect to see. A SASE platform supports these requirements through centralised logging, policy versioning with approval timestamps, identity-based access controls, and standardised evidence exports for audit preparation.
How SASE components map to healthcare security needs
| Healthcare requirement | SASE component | What it does |
|---|---|---|
| Role-based clinical access | ZTNA | Grants per-application access based on user identity and device posture |
| Web threat protection | Secure Web Gateway (SWG) | Filters web traffic, blocks malware domains, enforces acceptable use |
| Central firewall policy | Firewall-as-a-Service (FWaaS) | Applies consistent security rules across all sites from the cloud |
| Multi-site connectivity | SD-WAN | Connects campuses, clinics and remote sites with prioritised, encrypted traffic |
| Medical device isolation | NIAC hardware | Provides inline isolation for agentless devices, permitting only approved flows |
| Device compliance checks | Device Posture Check | Verifies OS version, encryption status and endpoint protection before granting access |
| Audit trail and reporting | Single console with API | Centralised logging, policy versioning and SIEM integration for NIS2 evidence |
This integrated approach means a hospital IT team manages one platform instead of six separate products. Policy changes propagate instantly across all sites. When a device fails its posture check, access is revoked in real time.
What a phased SASE rollout looks like in a hospital
Rolling out SASE across a hospital does not require a disruptive, big-bang migration. A phased approach delivers security improvements at each stage while keeping clinical operations running.
Phase 1: Identity and access foundation (weeks 1 to 4)
Connect your identity provider and synchronise clinical role groups. Publish two to three low-risk applications through ZTNA, such as the staff intranet, time registration and HR portal. Enable a baseline Secure Web Gateway policy that blocks known malicious domains. Run in monitor mode for the first two weeks to identify any access patterns that need adjustment.
Phase 2: Clinical application migration (weeks 5 to 12)
Extend ZTNA to business-critical clinical applications: the EHR system, PACS viewer, lab information system and pharmacy management. Implement device posture checks requiring disk encryption and current OS versions for managed endpoints. For BYOD devices used by visiting specialists, configure browser-based access with stricter scope limitations. Begin deploying NIAC hardware behind the first group of medical devices, starting with imaging equipment.
Phase 3: Full coverage and compliance readiness (weeks 13 to 24)
Connect branch locations and satellite clinics through SD-WAN. Extend NIAC isolation to all agentless device categories: infusion pumps, patient monitors, building management systems and security cameras. Activate TLS inspection on corporate devices where lawful and proportionate. Configure SIEM integration and automated compliance reporting. Document the operating model with review cycles and exception workflows for NIS2 board liability requirements.
Practical scenarios in European healthcare
Regional hospital group with four campuses. A Belgian hospital group replaced site-specific VPN concentrators with cloud-managed ZTNA. Clinicians at any campus now authenticate once and access their permitted applications without connecting to the full network. SD-WAN connects all campuses over encrypted links with automatic failover. When one site’s internet connection dropped during a storm, traffic rerouted through backup links within seconds. The group’s IT team manages all four campuses from one console.
University clinic with research and clinical networks. A university hospital separated research data access from clinical systems using identity-based policies. Researchers reach lab data through ZTNA with additional posture requirements, including mandatory full-disk encryption and institutional device registration. Clinical staff access the EHR through a separate policy set. The Secure Web Gateway blocks data exfiltration attempts through cloud storage services on clinical workstations. All access decisions are logged centrally for ethics board and NIS2 reporting.
Care network with home nursing and mobile teams. Nurses visiting patients at home access the care coordination platform through ZTNA on managed tablets. Device posture is verified before each session. The SWG filters web traffic on these devices regardless of which network they connect to, whether it is the patient’s home Wi-Fi, a mobile hotspot or the office network. The nursing organisation’s IT coordinator manages everything from a single dashboard, including policies for the 30 agentless printers and label makers at distribution points.
How Jimber makes SASE work for healthcare organisations
Jimber delivers Real SASE in one cloud-managed platform, combining Zero Trust Network Access, Secure Web Gateway, Firewall-as-a-Service and SD-WAN under a single policy model. Device posture gates every access request by default. For medical equipment, IoT sensors and building management devices that cannot run agents, NIAC hardware provides inline isolation that permits only the specific communication flows each device requires.
The platform is built with European data sovereignty in mind. Data processing stays within EU boundaries. There is no US parent company and no CLOUD Act jurisdictional conflict, which simplifies compliance conversations with regulators and patient advocacy bodies.
For healthcare organisations working through service partners, the multi-tenant architecture allows MSPs to manage multiple hospital environments from one console with shared policy templates, transparent per-user pricing and predictable margins.
The ransomware prevention playbook explains how each SASE component maps to a specific stage of the ransomware attack lifecycle, from initial access through lateral movement to data exfiltration.
Frequently asked questions
Is SASE suitable for small hospitals and clinics?
Yes. A cloud-managed SASE platform scales down as well as up. A single-site clinic with 50 users can start with ZTNA for two or three critical applications and a baseline web filtering policy, then expand as needed. There is no minimum site count or user threshold.
How does SASE handle medical device security without agents?
Inline isolation hardware sits between agentless medical devices and the rest of the network. Each device class is configured with allowed communication flows only. An MRI scanner communicates with the PACS server and its update service. Everything else is blocked at the hardware boundary.
Does SASE replace existing hospital firewalls?
Not necessarily. SASE complements existing firewalls for north-south traffic while adding identity-based access control, web security and microsegmentation that traditional firewalls do not provide. Many hospitals run both during a transition period.
What NIS2 evidence does a SASE platform provide?
Centralised access logs tied to user identity and device posture, policy change history with approver details and timestamps, incident detection and containment records, and standardised evidence exports. These align with CyberFundamentals requirements for essential entities in Belgium.
Can visiting specialists and contractors access hospital systems securely?
Yes. ZTNA supports temporary, time-bound access with step-up authentication requirements. Visiting specialists authenticate, their device posture is checked against a stricter baseline, and they receive access only to the specific applications agreed for their visit. All sessions are logged and auditable.
How long does a hospital SASE deployment take?
Most hospitals reach a working initial deployment within four to six weeks, starting with ZTNA for priority user groups and a baseline web security policy. Full coverage across all sites, devices and user categories typically takes three to six months depending on the number of locations and complexity of the medical device environment.
