MWC is done. The badge is off. The conversations are not.

What stood out most? Telecom security is a real operational priority.

P1 Security will be part of the Online [un]prompted conference this week.

Philippe Langlois, our founder and CEO, will moderate a lunchtime Zoom chat session titled:

Defense and Offense of Critical Infrastructure in the Age of AI

“Open it temporarily so it works” is how 5G networks get permanently exposed.

“No firewall matrix, no traffic flow visibility, so people open the network until things work… then leave it like it is.”

Physical access is not “local only”. In many environments it can become a network foothold, then pivot via the management plane, weak segmentation, insecure remote access, or stolen creds until the 5G core is reachable.

How does physical exposure translate into risk for mobile critical infrastructure, and how can teams reduce it without slowing operations down?

Risk Matrix Overview showing exposure levels across telecom domains. Rows include Management Plane, Signalling Plane, Supply Chain, Virtualization Stack, and Monitoring and Analysis. Columns include 4G RAN, 5G RAN, 4G Packet Core, 5G Packet Core, IMS and VoLTE Core, and Legacy 2G and 3G. Cells display color coded risk levels such as Low, Moderate, High, and Critical, with some areas marked as Unknown. The matrix highlights higher exposure in Legacy 2G and 3G as well as in core and signalling domains.

We released the Telco Attack Surface Matrix to help teams visualise exposure across RAN, Core, IMS, signalling and more. Try it and share your feedback so we can improve it. telcoasm.p1sec.com #telcosec

Weak passwords still break 5G in 2025. No zero days needed. If your access controls rely on bad defaults, start fixing them.

In 5G, you don’t lose the network when someone gets in you lose it when you realize there was never proper control in the first place.

🎥 O-RAN: Disaggregation = Bigger Attack Surface

More flexibility means more interfaces — and more exposure.

In this clip, we break down the real risks we see in the field.

Responsible Vulnerability Disclosure at P1 Security – Full Policy Breakdown Explore how P1 Security discloses telecom vulnerabilities via a structured 180-day process, CVE coordination, and its private VKB platform to help protect operators and critical infrastructure.

🚨 Many telco vulns never get CVEs.
Vendors delay, ignore, or silently patch.
Operators? Left in the dark.

At P1 Security, we follow a 180-day disclosure policy—document and publish in our private VKB when silence persists.

O-RAN isn’t just open — it’s a full shift in how mobile networks are built.

In the intro to our webinar, we lay the groundwork: what O-RAN is, and why it introduces both flexibility and risk.
