At Cellusys, we empower mobile operators to grow revenue, secure their networks, and enhance subscriber experience. Our technology gives operators clear insights and comprehensive control over signalling, with a focus on roaming, security, IoT, and analytics. Our products are consistently rated #1 year after year across Signalling Firewall, Steering of Roaming, SMS Firewall, and Voice Firewall — a distinction no other vendor has achieved. Since our inception in 2005, when we brought together a team with a depth of expertise in signalling, technology, and IP not seen elsewhere, we have continually led the way — in deploying Diameter-ready Steering of Roaming and Signalling Firewall systems, advancing event-driven steering, and supporting multi-generation mobile networks from 2G to 5G. Today, our solutions serve more than 1.35 billion subscribers worldwide. Driven by innovation, customer collaboration, and a readiness to rethink how things should be done, we remain the commercial and common-sense choice for mobile network operators.
