Fraud & Security
Cellusys Fraud & Security enables mobile operators to detect, prevent and control signalling and messaging security risks in real time across SS7, Diameter, SIP, GTP, HTTP/2 and SMS environments.
Operator challenges
- Cross-protocol attack scenarios spanning SS7, Diameter, SIP, GTP and SMS
- Voice fraud including CLI spoofing, IRSF, Wangiri, flash call abuse and SIM box bypass
- Subscriber data exposure through signalling exploitation
- Revenue leakage from grey routes and interconnect abuse
- Regulatory and GSMA compliance requirements
- Limited visibility across legacy and next-generation signalling layers
How the platform works
The platform inspects signalling and messaging traffic across all supported protocols in real time, either inline or in monitoring mode at interconnect boundaries. Configurable, protocol-aware rules are applied in line with GSMA recommendations and operator-defined policies.
It correlates signalling events and traffic behaviour across SS7, Diameter, GTP, SIP, HTTP/2 and SMS to identify coordinated threat patterns. Detection is enhanced through risk scoring and ongoing intelligence updates, with configurable actions including blocking, modification, rate limiting, or alerting.
All activity is logged and surfaced through reporting and dashboards, supporting operational visibility, compliance monitoring, and integration with external systems.

Deployment
Deployable inline or in monitoring mode across signalling and messaging environments, including SS7, Diameter, SIP, HTTP/2 and GTP. Integrates with STP, DRA, SBC and core signalling elements, with REST API and SIEM integration for external systems.
Available on-premises or as a managed service, with deployment covering configuration, testing and operational handover. Security rules are configurable and aligned with GSMA guidelines and operator requirements, with optional Professional and Managed Services support.
