In-House Tools for VoIP Security Assessment Service

One of our core strengths has been our ability to adapt to challenging customer environments and requirements. We have been able to consistently meet these challenges through a strong process of research and development. Some of the many tools we have developed over the years are given below.

[+] Read More

sdFinder - Identifies internal hosts on non-contiguous IP ranges. It allows us to detect sensitive information about our clients commercial, intranet and extranet networks.

webDiscovery - Identifies as many applications as possible on Client web-servers. The applications discovered through webDiscovery allow us to provide a superior web application security testing service than competitive services and products. It allows us to increase the scope of the audit and cover more areas that could be attacked by malicious users; that would not be covered by a traditional audit.

networkMapper - Network Mapper uses proprietary technology to be able to identify alternative network routes to bypass security mechanisms such as IDS/IPS/Firewall etc. It allows our experts to bypass existing security implementations and gain direct access to the systems behind them.

webTester - Utilizes our Benchmark Development System to ensure that we can identify maximum vulnerabilities in applications through automated mechanisms. Along with flaws that are known, it uses in-house research to test for vulnerabilities that are not in the public domain. It allows us to automate the process of identifying and testing known and unknown vulnerabilities in web-applications and strike a cost-effective time to effort ratio.

VA Framework - Integrated solution developed by our security experts that have an expertise in the vulnerability assessment domain. It allows us to integrate the manual and automated testing processes with commercial and open-source software. Our Integrated Reporting Engine allows us to cross-reference information from all the different components and generate a report based on our Client's requirements.

PT Framework - Integrated solution developed by our security experts that have an expertise in the penetration testing domain. It allows us to integrate the manual and automated testing processes with commercial and open-source software. Our Integrated Reporting Engine allows us to cross-reference information from all the different components and generate a report based on our Client's requirements.

webSpider - Uses advanced HTML, Java Script, Ajax, Flash and XML parsing engines to identify and map as much of the client applications as possible. This not only assists our automated webTester engine, but also assists in carrying out the manual testing process in an efficient manner. It allows us to attain a cost-effective balance between thorough testing and time required.
