Telecommunications Security Act Compliance — Code of Practice & Ofcom
The Telecommunications (Security) Act gives UK public telecoms providers strong legal security duties. Detailed requirements sit in the Electronic Communications (Security Measures) Regulations 2022 and the Code of Practice, which sets expectations by provider tier and timeline. Ofcom monitors and enforces.
Mutex Systems helps providers and their suppliers map the measures, assess network and supply-chain security, and evidence compliance to Ofcom — the UK counterpart to the PTA CTDISR work we do in Pakistan.

Telecoms security across two jurisdictions
Our CTDISR experience with Pakistani operators carries over directly to TSA: segmentation of security-critical functions, privileged access and supply-chain control.
- TSA measures mapping
- Network and supplier security assessments
- Monitoring and incident response for telecoms
TSA and CTDISR side by side
grComply can hold the TSA measures alongside PTA CTDISR-2025 and ISO 27001, which suits operators and vendors working in both the UK and Pakistan.
- Security measures as tracked controls
- Supplier risk register
- Cross-mapping to CTDISR and ISO 27001
- Evidence ready for Ofcom requests
grComply is Mutex Systems' own multi-tenant GRC automation platform — the framework library, hybrid scanning, risk and audit workflow, and AI-assisted compliance behind every point above are live in production today.

Who does the Telecommunications Security Act apply to?
Providers of UK public electronic communications networks and services. Requirements are proportionate to provider size, with the Code of Practice grouping providers into tiers.
Who enforces the TSA?
Ofcom monitors compliance and can investigate and fine providers that fail to meet their security duties.
How does the TSA compare with PTA CTDISR in Pakistan?
Both set legally binding security requirements for telecoms operators, covering network security, supply chain and incident handling. Mutex Systems works with both regimes.
