BT SD-WAN and SASE for NHS and Healthcare

Impact on patient care. Healthcare organisations depend on network connectivity for every patient interaction, clinical decision and administrative process. When networks fail or perform poorly, clinicians cannot access patient records, diagnostic images experience delays, telehealth consultations freeze mid-session, and critical alerts from connected medical devices fail to reach the appropriate staff. The result is delayed treatment decisions, compromised patient safety and potential regulatory breaches.

Operational strain. Traditional healthcare network architectures struggle with operational demands. MPLS circuits are expensive to deploy across geographically dispersed sites and inflexible when services relocate or new facilities open. Backhauling all traffic through central data centres can introduce latency that degrades real-time applications (PACS and telehealth platforms), leading to single points of failure, with guest WiFi, medical IoT devices and remote working staff all competing for bandwidth.

SD-WAN and SASE address these challenges through application-aware traffic management, supporting multiple connectivity types, providing centrally managed security that scales across distributed sites and minimising the need for on-site expertise.

GP Surgeries and Primary Care. Continuous connectivity for electronic patient records, e-prescribing and referral systems. Extended network outages force practices to revert to paper-based processes, creating patient safety risks and administrative backlogs that take days to clear.

Acute Hospitals. PACS requiring rapid transfer of diagnostic images (often several hundred megabytes per study), real-time patient monitoring transmitting continuous vital signs, and laboratory information systems coordinating thousands of test results daily. Slow PACS performance means radiologists cannot review images promptly, potentially delaying time-critical diagnoses.

Community Healthcare. District nursing teams, community mental health services and rehabilitation centres often operate from smaller sites with minimal IT support. Network reliability is essential for mobile clinicians accessing records during home visits (often via 4G/5G), secure messaging between care teams, and video consultations with patients who cannot travel.

Teleradiology and imaging. Standard 3D mammography files are often multiple gigabytes per examination. Radiology departments with multiple consultants simultaneously accessing PACS during morning reporting rounds generate burst traffic reaching 2 to 3 Gbps, requiring bandwidth aggregation across multiple circuits to prevent image rendering queues. SD-WAN broadband links reduce transfer time, enabling radiologists to access imaging studies without clinical workflow interruption during on-call emergency trauma assessments.

Telehealth and VoIP. Real-time video consultations and VoIP communications require strict latency and jitter tolerances. Industry standards state latency should remain under 150ms and jitter under 30ms. Forward Error Correction (FEC) capabilities of SD-WAN enable reconstruction of lost packets in real-time without retransmission delays, maintaining audio and video quality even when packet loss reaches 1 to 2 per cent.

EHR performance. Legacy connections with 100 to 200ms latency create visible delays in screen transitions, forcing clinicians to pause between clicks. SD-WAN deployments achieve consistent sub-50ms round-trip latency through path selection optimisation, ensuring instantaneous screen updates that match on-premises performance.

Data (Use and Access) Act 2025. Mandatory data auditing and access control requirements for healthcare organisations. SD-WAN supports the obligation through centralised logging and policy enforcement.

AI-assisted diagnostics and human-in-the-loop. UK healthcare providers integrating AI-assisted diagnostic tools face specific human oversight requirements under DUAA. Network-induced delays displaying AI-generated diagnostic overlays on high-resolution CT scans can create screen lag that impedes human intervention (required under DUAA Article 22A). SD-WAN architectures resolve this by supporting AI-assisted radiology workflows with sub-50ms latency.

Encryption and NHS DSPT. NHS 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 the organisation generates, stores and rotates cryptographic keys independently.

Clinical Performance. Detail how the solution prioritises EHR, PACS, imaging and telehealth traffic across MPLS and 5G. Safety-critical traffic requires low jitter and zero packet loss. NHS DCB0129 Standard and HHS HICP Guidance apply.

Protocol Support. Confirm support for DICOM, HL7 and FHIR protocols without MTU or asymmetric routing issues. Medical protocols behave differently than generic SaaS traffic.

UK Safety Standards. Map network and security policy changes to DCB0129 and DCB0160 clinical risk management standards. Statutory obligations to manage clinical safety risks from network services.

Compliance Mapping. Provide a mapping for NHS DSPT (CAF aligned) and HIPAA technical safeguards (45 CFR 164.312). Statutory compliance requires clear traceability between network controls and regional data laws.

IoMT Security. Describe the segmentation model for medical hardware that cannot support security agents or frequent patching. Unmanaged clinical devices are primary breach vectors.

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.

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.

Data Residency. Confirm ability to restrict traffic inspection and log residency to specific regions (UK, US, Canada). Healthcare contracts mandate strict data residency to comply with local privacy statutes.

Step 1, select healthcare requirements. Choose from pre-written RFP questions covering HIPAA and DUAA 2025 compliance, EHR integration, DICOM and PACS imaging, telehealth QoS, multi-branch failover and IoT device support. Add bespoke questions using AI assistance.

Step 2, publish to scored vendors. The RFP is published to Netify's curated marketplace of 30+ SD-WAN and SASE vendors and managed service providers, each independently assessed using the Netify Market Index methodology.

Step 3, compare responses. Vendors respond directly through the platform. AI-assisted scoring evaluates responses against the stated requirements, producing a side-by-side comparison the buyer can share with procurement stakeholders.

Step 4, shortlist and engage. Move from RFP to vendor engagement without sales intermediaries, gated content or pay-to-play rankings.

Scope and transparency. Netify is not a network or security service provider and does not certify compliance. We translate common requirements (NHS DSPT, HIPAA, clinical safety) into procurement questions and require suppliers to evidence their claims. Final compliance decisions remain with the buyer and their appointed advisors.
