Security Consulting and Expertise for Telecom and Mobile Operators

Telecom Signaling Security Consulting

The telecom infrastructure is opening with Value Added Services provided by third parties, growing Signaling Interconnects and expansion of attack vectors and entry points through new services such as Femto Cells access networks or 3G convergent services integrated with tcp/ip.
Due to the opening of the telecom world to an ever growing set of business partners and customer services, new threat are on the rise.
Few telecom companies have a real understanding of the risks linked to their Telecom Signaling network and the new connections between their Core Network and the Internet.
P1 Security helps telecom and mobile operators assess and analyze their security in their core network and signaling perimeters.
