Next-Generation RASP
The Market Leader in Runtime Application Self-Protection (RASP)
Our easy to install software supports any application without impacting performance to protect against any attack, with integrations to any DevOps toolchain products for cross-team visibility.
“It’s refreshing to work with a security product that not only provides exceptional security benefits, but also prioritizes performance, reliability, and overall operational manageability.
Signal Sciences is easy for our DevOps team to support, which allows us to focus on the security capabilities it provides, rather than fighting with basic operational issues.”

Jenner Holden
VP of INFORMATION SECURITY
“We selected Signal Sciences because it just worked. We didn’t want to divert internal resources to maintain coverage by tuning security controls..
Signal Sciences seamlessly integrated into our toolset, while giving us realtime security visibility—without the noise.”

Ryan Shaltry
TECHNICAL ARCHITECT AND DEVELOPER
“The architectural openness and extensibility of the product, along with its performance and scalability ensured that Signal Sciences could support us well into the future. Our team is lean and Signal Sciences extends our capacity by providing us with more ‘finished data’ versus the raw log data we had worked with the past. In other words, we get actionable insights, faster and with a higher degree of confidence in the data’s accuracy.“
