🎥 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.

🚨 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.
