Embedding the DPI engine R&S®PACE 2 into the web application firewall for real time granular insights into applications and protocols


Detecting application vulnerabilities fast and reliably; improving performance and manageability of network traffic; boosting return on invest & speeding up time-to-market

The need: fine-grained IP traffic visibility to enable comprehensive network perimeter protection

Web applications and web servers are increasingly becoming prime targets for cyberattacks because regular perimeter security solutions only secure the network level and control access to it but do not focus on the application layer or end-user processes such as HTTP and SMTP. Attacks on this layer, such as SQL injection, cross-site scripting (XSS) and DDoS attacks, present an enormous challenge, as malicious code can masquerade as valid client requests and normal application data. In order to provide customers with a strong and reliable solution, Indigo Software needed a high-performance DPI engine that would enable its firewalls to analyze HTTP requests and responses to detect malicious behavior.

Indigo Software chooses DPI engine from ipoque for fast and up-to-date classification capabilities

Indigo Software was looking for a DPI solution to meet its increasing need for fast performance with a high application and protocol classification accuracy. Furthermore, they required a DPI technology that would not impact their throughput and receive regular application and protocol signature updates without needing extensive custom development and maintenance. With R&S®PACE 2, they found an easy-to-integrate DPI engine that operates in real time at a speed of multiple Gbps. The weekly protocol and application signature update ensures that Indigo Software firewalls can rely on up-to-date classifications when filtering network traffic.

“We had evaluated open source alternatives as the core for our web application firewall; however, they did not offer the performance and reliability required for our customers. The DPI engine R&S®PACE 2 gave us what we needed—from carrier-class performance and reliability to detection of applications, protocols and even encrypted applications to excellent developer documentation and sample code.”

A reliable solution for the best protection against application layer attacks

After integrating the DPI engine R&S®PACE 2 Indigos web application firewall is now able to identify, classify, and detect packets with data payloads that hackers have obfuscated—e.g., executables concealed in an HTTP request. By providing their customers with thorough visibility into their networks and empowering them to control unwanted or potentially malicious traffic, Indigo Software saw a dramatic increase in customer satisfaction. Through analyzing web traffic and associated formats such as HTML and Javascript, the firewall is now better able to restrict specific application requests or commands, detect malicious activity and halt potential threats. Consequently, app vulnerabilities are eliminated before they can be exploited by threat actors, thereby preventing data loss, application-layer DDoS, zero-day attacks and other risks. By licensing R&S®PACE 2 instead of building its own custom deep packet inspection software, Indigo Software sped up its time-to-market, reduced development time, cost and resource requirements whilst focusing on its core competencies.
