Unified network performance connectivity

We combine SD-WAN with BT’s resilient UK infrastructure to prioritise your critical applications, on-premise or in the cloud.

  • Intelligent routing: automatically steers traffic over 5G, Fibre, or Broadband to minimise latency.
  • Operational efficiency: Automated deployment via the one business stack reduces manual configuration.
  • Single SLA: a single SLA and unified service management cover both connectivity and security.
Managed zero-trust and identity-driven security

We replace traditional VPNs with Zero Trust Network Access (ZTNA), granting access based on user identity and context.

  • VPN replacement: a faster, more secure hybrid-work experience without unnecessary backhaul.
  • Granular access control: limits users to the specific applications they need, reducing your attack surface.
  • Expert policy management: BT specialists manage and optimise policies as your organisation evolves
Converged threat detection and prevention

We deliver cloud-based security services closer to your users and applications, helping you stay protected wherever traffic flows.

  • Real-time threat blocking: Instantly blocks malware, phishing, and malicious sites at the network edge.
  • Data Protection (DLP): advanced monitoring to prevent sensitive data leaks across cloud apps like M365.
  • Sovereign assurance: UK-resident logging and management to meet local regulatory standards.
