CTDISR-2025 Compliance Guide — PTA's Telecom Cybersecurity Regulation
CTDISR-2025 — the Critical Telecom Data and Infrastructure Security Regulations — is the most actively enforced cybersecurity regulation in Pakistan, with a formal PTA audit-firm registration regime behind it. The August/October 2025 revision expanded the original 2023 regulation with an explicit zero-trust architecture requirement, mandatory multi-factor authentication, and a dedicated cloud-security compliance domain.
Mutex Systems is a PTA-Approved Cyber Security Auditor (CAT-1 to CAT-4) with direct experience running CTDISR-2025 gap assessments and inspection preparation — not a theoretical reading of the regulation text.

Key Requirements
A Practical Compliance Path
- 01
Gap Assessment
Map current controls against the CTDISR-2025 clause set — zero-trust, MFA, data localisation, cloud domain, and nTSOC integration — to identify what is already in place and what is missing.
- 02
Remediation Roadmap
Prioritise technical and process gaps by risk and inspection likelihood, with clear ownership and timelines for each control.
- 03
Controls Implementation
Implement zero-trust architecture changes, roll out MFA across privileged access, and confirm data-residency arrangements for any offshore infrastructure.
- 04
Inspection Evidence Pack
Compile documentation and evidence formatted for how PTA's inspection team actually reviews compliance, not a generic audit template.
How grComply Automates CTDISR-2025
CTDISR is loaded into grComply as a seed framework — Mutex's own flagship use case, replacing the annual manual audit crunch with a live completion percentage.
- Agentless external scans check TLS/certificate/DNS/exposed-service posture continuously against CTDISR clauses
- Zero-trust and MFA control status derived from scan findings plus evidence — not a manual annual survey
- Used internally by Mutex to manage its own CAT-1 to CAT-4 registration evidence and technical-resource roster for renewal

Common Questions About CTDISR-2025
What is CTDISR-2025 in simple terms?
CTDISR-2025 is the Pakistan Telecommunication Authority's binding cybersecurity regulation for telecom operators, ISPs, and the cloud infrastructure and Critical Information Infrastructure that serve them. It mandates a zero-trust security model, mandatory multi-factor authentication, data localisation, a dedicated cloud-security compliance domain, and integration with PTA's national Telecom Security Operations Centre (nTSOC).
What changed in the 2025 revision of CTDISR?
The 2025 revision, finalised in stages through August and October 2025, expanded the original 2023 regulation with an explicit zero-trust architecture requirement, mandatory MFA across privileged access, a dedicated cloud-security compliance domain covering public, private, and hybrid environments, and deeper nTSOC integration requirements. Operators compliant against the earlier text should not assume automatic compliance against the current 2025 regulation.
Who needs to comply with CTDISR-2025?
All PTA-licensed telecom operators — cellular, Long Distance and International (LDI), Local Loop (LL), and ISPs — plus any cloud or data-centre operator serving telecom Critical Information Infrastructure, and the online/digital media platforms distributed over PTA-regulated networks.
What does the CTDISR data-localisation requirement actually mean?
Critical Information Infrastructure data must remain within Pakistan unless PTA grants written cross-border approval. This affects any operator or cloud provider using offshore infrastructure for data falling under the CII designation, and is one of the more commonly missed requirements in gap assessments.
How long does a CTDISR-2025 compliance programme take?
Timelines depend on the existing control baseline, but a typical gap-assessment-to-remediation programme runs several months, covering zero-trust architecture changes, MFA rollout, nTSOC integration, documentation, and inspection-evidence compilation. Programmes are scoped individually against current PTA inspection cycles.
Is Mutex Systems qualified to run a CTDISR-2025 assessment?
Yes. Mutex Systems is a PTA-Approved Cyber Security Auditor under the CAT-1 to CAT-4 registration regime — a direct, verifiable regulatory relationship, not a claimed capability.
