The clinical connectivity challenge
Legacy WAN architectures cannot support healthcare’s demands for clinical application performance, multi-site connectivity and regulatory compliance, however SD-WAN and SASE solutions provide the answer through application-aware routing, centralised management and integrated security for NHS Data Security and Protection Toolkit (DSPT), UK GDPR and Caldicott Principle compliance.
BT delivers this combination through two vendor platforms, Cisco Meraki and Fortinet, with Netify acting as an Authorised Partner of BT for design, deployment and ongoing support across UK healthcare estates.
Different healthcare operating environments
Although there are often many common themes and demands across the healthcare sector, it’s easy to forget that not all healthcare organisations’ needs are the same, operating across different site types, each with distinct connectivity requirements and tolerance for failure. Understanding these operational differences is essential when evaluating SD-WAN and SASE solutions, as the consequences of network failure vary dramatically depending on location type and the clinical systems that depend on connectivity.
GP surgeries and primary care
GP surgeries and primary care sites depend on continuous connectivity for electronic patient records, e-prescribing and referral systems. Even though some clinical systems offer limited offline functionality for appointment notes, these capabilities have significant restrictions, clinicians cannot access patient history, medication records or test results without live connectivity.
Extended network outages can force practices to revert to paper-based processes, creating patient safety risks from incomplete information and administrative backlogs that take days to clear.
Acute hospitals and multi-site trusts
Acute sites run bandwidth-hungry PACS, DICOM imaging, Epic or Cerner EHR, theatre scheduling and clinical IoMT devices in parallel. BT Managed SD-WAN on Meraki or Fortinet aggregates BTnet leased lines, FTTP and cellular underlays to carry these workloads with application-aware prioritisation and integrated security.
Community facilities, outpatient clinics and pharmacies join the same overlay with lighter underlays and Zero Trust Network Access for mobile clinicians.
Technical performance standards
Healthcare SD-WAN deployments must satisfy specific performance thresholds to support clinical workflows without compromising patient care delivery.
High-bandwidth imaging
Standard 3D mammography files are often multiple gigabytes per examination, creating significant bandwidth demands for radiology departments. Legacy connections require far longer to transfer a single high resolution imaging file, introducing delays in diagnostic workflows where radiologists must compare current studies against previous examinations.
SD-WAN broadband links reduce this transfer time to a fraction of the time, enabling radiologists to access imaging studies without clinical workflow interruption during on-call emergency trauma assessments.
- PACS traffic burst (08:00, 09:00 rounds, 10:00) 3 Gbps diagnostic accuracy: UK NHS trusts report that radiologists examining CT scans with thousands of individual slices require instant image progression to maintain diagnostic accuracy, with any buffering or lag introducing eye strain and potential diagnostic errors during multi-hour reading sessions.
- Burst traffic handling: Radiology departments with multiple consultants simultaneously accessing PACS during morning reporting rounds generate burst traffic reaching 2-3 Gbps, requiring bandwidth aggregation across multiple circuits to prevent image rendering queues.
Compliance and security 2026: The Data (Use and Access) Act
Healthcare SD-WAN deployments must satisfy evolving UK and international regulatory requirements whilst maintaining patient data protection during clinical workflow optimisation.
Data (Use and Access) Act 2025 (DUAA)
The Data (Use and Access) Act 2025 (DUAA) introduces mandatory data auditing and access control requirements for healthcare organisations processing patient information. SD-WAN platforms support these compliance obligations through centralised logging and policy enforcement, enabling healthcare organisations to demonstrate which clinician accessed which patient record, when access occurred and which clinical applications processed protected health information.
AI-assisted diagnostics and human-in-the-loop
UK healthcare providers integrating AI-assisted diagnostic tools into radiology and triage workflows face specific human oversight requirements under the Data (Use and Access) Act 2025 (DUAA).
Network-induced delays displaying AI-generated diagnostic overlays on high-resolution CT scans create screen lag that impedes human intervention (required under DUAA Article 22A), potentially creating bottlenecks in critical care pathways.
SD-WAN architectures resolve this by supporting AI-assisted radiology workflows with sub-50ms latency for simultaneous display of original DICOM imaging studies alongside AI-generated annotations.
Encryption and NHS DSPT
NHS Data Security and Protection Toolkit (DSPT) and HIPAA regulations mandate that encryption keys for patient data transmissions remain under healthcare organisational control rather than third-party transport providers. Healthcare SD-WAN deployments implement customer-managed encryption (CME) where healthcare organisations generate, store and rotate cryptographic keys independently of connectivity providers.
BT SD-WAN and SASE capability pillars for Healthcare
BT’s Managed SD-WAN and SASE capability for healthcare covers eight pillars across Cisco Meraki and Fortinet. Each pillar maps to a specific clinical or regulatory requirement that buyers should evidence during procurement.

| IoMT Security | Describe the segmentation model for medical hardware that cannot support security agents or frequent patching. | Unmanaged clinical devices are primary breach vectors requiring network level isolation. FDA Medical Device Cybersecurity. |
| Identity and Access | Explain ZTNA enforcement for clinicians and support for “break glass” emergency access. | Clinical workflows require rapid entry during emergencies without creating permanent security gaps. ICO Special Category Data. |
| Threat Protection | Detail DNS security and SWG policies specifically tuned for healthcare vendors and clinical allowlists. | Generic security policies often disrupt essential clinical portals and telehealth sessions. HSCC Threat Alignment. |
| Data Residency | Confirm ability to restrict traffic inspection and log residency to specific regions like the UK, US, or Canada. | Healthcare contracts often mandate strict data residency to comply with local privacy statutes. Canada PIPEDA and PHIPA. |
Frequently asked questions
How does SD-WAN optimise DICOM and PACS image transfers?
SD-WAN applies application-aware routing to prioritise DICOM and PACS traffic, supports MTU-appropriate settings for medical protocols, and aggregates bandwidth across multiple circuits to absorb the 2-3 Gbps bursts generated during morning reporting rounds.
Can SD-WAN replace private MPLS circuits for patient records?
Yes. SD-WAN overlays support EHR, PACS and imaging traffic across MPLS, 5G, BTnet leased lines, FTTP and SOGEA underlays, with encrypted transport and centralised policy enforcement that meets NHS DSPT and UK GDPR requirements.
What are the requirements for cloud-hosted Epic EHR?
Cloud-hosted Epic EHR requires sub-50 ms latency to the regional Epic data centre, predictable jitter, and prioritisation for clinical application traffic. BT SD-WAN on Meraki or Fortinet delivers these thresholds with application-aware routing and underlay bonding.
How does SD-WAN support the Data (Use and Access) Act 2025?
Through centralised logging and policy enforcement, SD-WAN demonstrates which clinician accessed which patient record, when access occurred, and which clinical applications processed protected health information. Customer-managed encryption keeps keys under organisational control, as required by DUAA and NHS DSPT.
How are mobile ambulances and community clinics supported?
Cellular underlays (4G and 5G) on Meraki or Fortinet appliances deliver live EHR and telehealth access from ambulances and community sites, with automatic failover to wired underlay when available and ZTNA enforcement for clinicians accessing records on the move.
