Signalling security is crucial for 5G networks, but the market is evolving. Traditionally reliant on hardware-based signalling firewalls, the industry is now witnessing a shift towards software solutions. ABI Research predicts a 50% annual growth in network security services and software, while hardware revenues stagnate. Georgia Cooke, a digital security research analyst, highlights that the demand for signalling security remains strong, but customers increasingly prefer software formats that offer user-friendly interfaces and seamless integration.
Despite the importance of signalling firewalls, approximately half of network operators still lack adequate protection. A recent deployment of Enea’s voice firewall in Telecom Egypt resulted in a remarkable 90% decrease in scam calls.
Historically, trust in these firewalls has been low, with many mobile network operators (MNOs) reporting high rates of missed attacks. However, advancements from companies like BroadForward and Mavenir are enhancing cloud-based solutions, making them more user-friendly and responsive to threats.
As cyber threats become more sophisticated and rapid, especially with the rise of AI-enabled attacks, the need for adaptable and manageable security tools has never been greater. While hardware firewalls will continue to exist, the increasing preference for software-based solutions signifies a transformative shift in the 5G security landscape, offering network operators the flexibility and agility they need to protect their systems effectively.
