Telecom network security where uptime is the whole product.
Telecom operators sit in an unusual position: critical national infrastructure in their own right, and the transport layer that every other critical sector depends on. We work across core, transport and access networks, the OT that keeps sites running, and the private networks now being deployed inside industrial facilities.

Critical infrastructure obligations
Regulatory and resilience requirements
Frameworks that shape a telecom programme.
Telecom security spans network standards, critical infrastructure regulation and — increasingly, as operators deploy private networks into plants — the industrial standards their customers are held to.
Core, transport and access network protection
Signalling security, interconnect exposure, network function isolation and the management plane that controls it all.
How we support you
- Signalling and interconnect exposure assessment
- Network function and slice isolation review
- Management plane and jump host hardening
- Privileged and vendor access redesign
- Configuration baseline and drift detection
- Segmentation between network domains
Private LTE and 5G in industrial environments
Where operators deploy private networks inside plants and ports, the network inherits the customer's industrial security obligations as well as its own.
How we support you
- Private network architecture security review
- SIM, identity and device onboarding controls
- Integration with plant zone and conduit design
- Edge compute and MEC security assessment
- Shared responsibility definition with the customer
- Alignment with IEC 62443 expectations
The operational technology behind the network
Power systems, generators, cooling, fire suppression and physical access control at exchanges, data centres and tower sites — often the least monitored part of the estate.
How we support you
- Site OT asset inventory and exposure review
- Building and power management system assessment
- Remote site connectivity and access control
- Environmental monitoring integration
- Contractor and maintenance access governance
- Segmentation from corporate and network domains
Regulatory and resilience requirements
Telecom-specific national security and resilience obligations, alongside general critical infrastructure directives such as NIS2 for European operations.
How we support you
- Obligation inventory and applicability analysis
- Resilience and continuity assessment
- Incident notification process design
- Supply chain and equipment vendor risk review
- Regulator submission support
- Audit readiness and finding closure
What a telecom engagement covers.
The same seven services run across every practice, so you can compare scope without re-learning the menu.
Risk assessment
Risk assessment across network domains and site infrastructure, prioritised by service impact rather than asset count.
Advisory & consulting
Architecture and governance guidance across network, IT and site OT — including where private network deployments inherit customer obligations.
VA-PT & security testing
Configuration review and controlled testing, scoped around maintenance windows so no test threatens service availability.
Compliance & audit readiness
Readiness for telecom-specific obligations and general critical infrastructure directives, with evidence mapped once.
Implementation support
Segmentation, privileged access redesign, management plane hardening and monitoring coverage across domains.
Security operations
Extending detection into network and site OT, with response procedures built around service continuity.
Training & capability
Capability building for network operations and field teams, plus industrial security briefings for private network staff.
