Security & Penetration Testing, Load & Performance Testing, Functional Testing

STINGA Protocol Simulator

Test and verification of network elements, network services and network performance is important to ensure network reliability and interoperability between network elements and user satisfaction.
STINGA Protocol Simulator
 is an essential tool for network operators and service providers in ensuring Quality of Service (QoS) and Quality of Experience (QoE), supporting security & penetration testing, load & performance testing, functional testing and troubleshooting.
STINGA Protocol Simulator
 is a cost-efficient test tool for Diameter simulation, SS7 simulation over TDM and IP/SIGTRAN, SCTP simulation, SIP-T simulation and ISDN PRI simulation.


STINGA Protocol Simulator supports security & penetration testing, load & performance testing, functional testing, conformance testing, regression testing, mobile testing and media testing, from prototyping-stage to final product. Testing new services, products, or software versions early in the development phase saves time, prevents errors, and ensures interoperability between network elements. When commercially released and distributed, all new network elements are verified to function in a real network environment and to deliver on its premises.

Generate various traffic conditions

STINGA Protocol Simulator can generate both real network conditions and custom traffic towards specific or all parts of a network. It can also regenerate problems or irregularities that have already occurred in a real network environment. This makes error tracking and searching easier, and customer experience can easily be tested to ensure high quality.
Conformance Test Suite Frameworks are included with STINGA Protocol Simulator. These frameworks contain a large number of test scripts and templates to simulate calls, data traffic etc. towards one or several parts of a network. Test scripts and templates can easily be customized for specific tests.
Test scripts related to the new “Guidelines for Independent Remote Interconnect Security Testing” from GSMA (GSMA FS.26 / GSMA FS.11) are also included.

Expert support & tailored solutions

To better fit our customers’ needs and requirements, we provide them with custom made and tailored solutions. All STINGA products are adapted to new technological changes and new protocols and versions are added continuously. Other protocols and national protocol variants are implemented on customer request. Expert support and product demonstrations are offered online.
