Network & communications security: the overlooked layer of cyber risk
Most cyber security budgets go toward endpoints, email and cloud accounts. Meanwhile, the network and telephony layer underneath all of it often gets far less attention than it deserves.
It's an understandable blind spot. Network infrastructure and phone systems tend to be set up once and left alone for years, quietly running in the background while attention shifts to newer, more visible threats. But that's exactly what makes them attractive targets — misconfigured routers, outdated firmware and unsecured VoIP systems are often the path of least resistance into a business.
Where the risk actually sits
Toll fraud on unsecured VoIP systems, unpatched network devices with known vulnerabilities, and unsegmented networks that let an attacker move freely once they're in — these are common findings when we run network assessments, even at businesses with otherwise mature security programmes.
Segmentation: the control that limits the damage
One of the most effective, and most overlooked, controls is network segmentation — separating guest wifi, staff devices, and critical systems so that a compromise in one area doesn't automatically become a compromise of everything.
Bringing telephony into the security conversation
As part of our Network & Communications services, we treat your phone systems and network infrastructure as part of the same security perimeter as your laptops and cloud accounts — because to an attacker, that's exactly what they are.
If your last network review happened when the equipment was installed, it's worth revisiting. Infrastructure that was secure five years ago isn't necessarily secure today.
