P1 Security

P1 Security operates in the layer where telecom meets threat: the signaling protocols, core networks, and radio interfaces that underpin mobile communications. Founded in 2009, the company's core focus is mobile network security - analyzing and defending the infrastructure that governments, carriers, and enterprises depend on. Their work starts with deep telecom vulnerability research; the team maintains a Vulnerability Knowledge Base cataloging over 2,000 telecom-specific flaws, a dataset informing both their products and the broader security community.

That research feeds into a concrete product stack. P1 builds and deploys Intrusion Detection Systems (PTM) for real-time network monitoring, alongside Attack Surface Management tools (PTA) for mapping exposure. They also offer specialized consulting across 5G, OpenRAN, and Private Network deployments - domains where traditional IT security models break down fast. The scope includes protocol-level analysis of SS7, Diameter, GTP, and the 5G core, threats ranging from subscriber tracking to network-level denial of service.

The team backs its technical credibility with visible industry engagement: presenting at top-tier security conferences, contributing to GSMA working groups, and shaping telecom security standards. They run cutting-edge training and certification programs as well. Over 50 telecom security assessments conducted across their client base suggest sustained, hands-on operational experience rather than just advisory work.
