DPI engine enhances web security solution

Rohde & Schwarz is supplying its DPI engine R&S PACE 2 to Indigo Software. It will enhance the softare company's web application security solution with protocol and application classification capabilities. R&S PACE 2 now serves as the core for their web application firewalls (WAFs), enabling them to obtain granular visibility of network traffic in order to analyse HTTP requests and responses to detect malicious behaviour.

Web application firewalls as provided by Indigo Software have become an indispensable component in the application delivery infrastructure as they offer Layer 7 web application security to prevent attacks such as SQL injection, cross-site scripting (XSS) and DDoS attacks.

WAFs are able to detect and block malicious activities behind inconspicuous website traffic that may slip through traditional security solutions. Indigo Software was looking for a DPI solution to meet its increasing need for fast performance, high application and protocol classification accuracy as well as a DPI engine with a very low memory footprint.

IT chose R&S PACE 2 for an easy-to-integrate software library that operates in real time at a speed of multiple Gbps. R&SPACE 2 receives weekly protocol and application signature updates which ensure that Indigo Software firewalls make accurate decisions on reliably classified traffic.

Since Indigo Software integrated the DPI engine into its WAF, customer satisfaction has greatly increased because they instantly saw significant improvements in application performance and availability, as well as a reduction in lag time.

“We had evaluated open source alternatives as the core for our web application firewall, however they did not offer the performance and reliability required by our customers. The Rohde & Schwarz DPI engine gave us what we needed—from carrier-class performance and reliability to the detection of applications, protocols and even encrypted applications to excellent developer documentation and sample code,” says Adam Murad, CTO at Indigo Software.
