5G Network Security

Securing the Journey to 5G

In an era where the evolution towards 5G is rapidly unfolding, telecom operators find themselves at a crucial juncture. The advent of 5G is not just a leap forward in technology; it is a transformative shift in the way we connect, communicate, and secure our digital landscapes. But, as we embrace the future, the legacy of 4G and 3G networks continues to play a vital role, requiring a robust cybersecurity framework that spans the entirety of our networks – from the edge to the core, outwards to the internet and beyond to other operators’ networks.

Clavister is at the forefront of this transformative era with our tailored telco-specific firewall, designed to address the complex cybersecurity challenges associated with the transition to 5G. Our solution recognises the critical need for the harmonious coexistence of legacy and next-generation networks, ensuring comprehensive protection every step of the way.
