Ask an operator where its attack surface is and the answer depends who is in the room: SS7, GTP, IMS, RAN, OAM. Each answer is right and none is complete. TelcoASM, the Telco Attack Surface Matrix, puts the domains in one structured self-assessment: 4G and 5G core, signalling, IMS and VoLTE, RAN, management platforms, supply chain. No scan, confidential. https://telcoasm.p1sec.com #TelecomSecurity #AttackSurface

Smishing is treated as an inbox problem. It isn't. The text can look ordinary. The abuse is in how the message is injected: sender identity spoofed over SS7, A2P grey routes slipping past the SMSC. A content filter reads the words, never the origin or route. Catching SMS fraud at scale needs signalling-layer visibility, not better wordlists. https://www.p1sec.com/blog/sms-based-attacks-the-hidden-threat-still-exploiting-mobile-networks #TelecomSecurity #SS7 #Smishing

EECC. NIS2. ENISA guidance. The EU 5G Toolbox. Each was written with its own scope and timeline. Read individually they are manageable. Read together, European telecom security rules overlap, cross-reference, and sometimes pull in different directions. Our whitepaper maps how these frameworks fit together and how they have evolved, for the teams who turn regulation into network controls. https://www.p1sec.com/white-paper/towards-harmonization #TelecomSecurity #NIS2 #Compliance

Deploy a private 4G or 5G network, CBRS or slicing, and you quietly become a mobile network operator. You now own a core, a RAN, subscriber SIMs and the signaling between them, usually with no telecom security team. The risks are telecom-specific: slice isolation failures, an exposed core and OAM, weak subscriber identity. IT scanners miss them. Secure it like an operator: https://www.p1sec.com/services/private-5g-security-private-4g-cbrs-slicing #Private5G #TelecomSecurity

Telecom security training is easier to judge when someone walks you through it. P1 Academy is our online telecom security training: expert-led video, quizzes, and hands-on labs from SS7 to 5G. Weighing it up for your team? We are happy to give you a 30-minute walkthrough: a live look at the platform and whether it fits. No slides, just your questions. Email contact@p1sec.com to set it up.

Thank you to CSAI, TEMA, and CMAI for hosting the National Conference on Telecom Security in the AI and Quantum Age (25 June, India International Centre, New Delhi). We came to listen: AI-driven threats to mobile networks, post-quantum readiness, and protecting the signaling and core that sit behind India's digital backbone. Plenty of sharp discussion and good conversations with operators, government, and researchers. Thank you to everyone we met for the warm exchange, and to the organising committee for the welcome. #TelecomSecurity #5G
