Telecoms operators face overlapping CNI obligations, legacy protocol risk, and a threat landscape that includes nation-state actors. TechSonar embeds senior security engineers to build continuous compliance, harden network infrastructure, and satisfy Ofcom and NIS2 requirements, without disrupting live services.
TSA
Telecoms Security Act obligations mapped and evidenced
NIS2
Essential entity requirements met across network and supply chain
Ofcom
Codes of practice aligned with continuous compliance monitoring
5G
Security architecture reviewed for new network deployments
The challenge
[01]
Telecoms operators are designated CNI. NIS2, the Telecoms Security Act, and Ofcom codes of practice impose strict security duties, with significant penalties for non-compliance.
[02]
From core network infrastructure and OSS/BSS platforms to customer-facing APIs and IoT endpoints, the telecom attack surface spans millions of devices and dozens of interconnected systems.
[03]
SS7, Diameter, and legacy signalling protocols carry known vulnerabilities that are difficult to remediate without disrupting live services. Modern 5G introduces new threat vectors alongside old ones.
[04]
Telecom networks depend on a small number of equipment vendors. Supply chain compromise, firmware integrity, and third-party ICT risk management are board-level concerns.
How we help
Mapping your security controls to the TSA and Ofcom codes of practice. Continuous compliance, not point-in-time assessments.
Bespoke security programmes aligned to NIS2 obligations for essential entities, built around your network, not a generic framework.
STRIDE and MITRE ATT&CK applied to core network, signalling layers, and customer data flows. Architecture-level risk identification before incidents occur.
Infrastructure-as-code security for cloud-native network functions, containerised workloads, and CI/CD pipelines deploying to production network environments.
Network, API, and application penetration testing across OSS/BSS platforms, customer portals, and internal tooling, with telecom-specific threat context.
Cut through the noise of overlapping regulatory obligations. An auditor-aligned programme that focuses effort on controls that close real exposure.
