Telco security barely warrants ‘C+’ grade

At MWC 2025, when the CTO of the UK’s National Cyber Security Centre gave telco security a “C+ at best” grade, it was underscored by essentially zero media coverage. Ironically, fewer than 400 of more than 100,000 MWC attendees were even present for the talk. So, in a report that includes telco security notes from meetings with core suppliers, dive into the compounding factors that have led to this poor ranking and what you should do to improve your security landscape.

You’ll explore:

• Why telco security is rated so poorly – Touting optimism bias, the CTO of NCSC admonished that telecommunications operators are being penetrated, not by sophisticated methods, but by default passwords and poor configurations.
• What the emerging risks are – In addition to standard risk profiles, AI-generated fakes, complicated infrastructure and worries over external China-nexus adversaries ranked high.
• Three areas to secure – Telco security is organised into telco network protection, enterprise network protection and user protection concerns. Telcos lament the limited vendor innovation in the telco network space, particularly.
• Fragmentation around user protection – In what could become a differentiator, there is increasing market segmentation according to whether telcos want to lead in protecting users against online scams or simply await direction from regulators.
• What GSMA’s open gateway APIs mean – This is driving new revenues and fraud prevention and security use cases that protect telcos, their enterprise customers (and those enterprise customers’ end users), featured prominently among use cases.
