At Cellusys, we empower mobile operators to generate more revenue, secure their networks, and make their subscribers’ experiences better. We design and build technology that gives operators clear insights and comprehensive control over their signalling, with a focus on security, IoT, roaming, and analytics applications. Our products have all been rated as Tier 1 in Signalling Firewall, Steering of Roaming and SMS Firewall in independent research. No other vendor has achieved this in all technical product categories. We have continually broken new ground since our inception in 2005, when we brought together a team with a depth of expertise in signalling, technology, and IP not seen elsewhere. Some of our milestones – we deployed the first Diameter-ready Steering of Roaming system worldwide; and the first Diameter-ready Signalling Firewall worldwide. Our technology serves more than 880 million subscribers worldwide. We’re rated a top innovator and a Tier 1 vendor in independent research – Rocco Innovator Report, 2017. We are not held back with preconceived notions of how things should or shouldn’t be done. With this, plus our creativity, and huge input from customers, we will remain leaders in innovation, and the commercial and common-sense choice for mobile network operators.
