Cybersecurity firm Sqreen has raised $14 million in a Series A round of investments. It helps developers to monitor and protect their web apps from vulnerabilities. Greylock Partners is leading the round, with participation from Y Combinator, Alven Capital and Point Nine.

Sqreen provides an Application Security Management platform with a technology known as Runtime Application Self-Protection Security, which uses to embed micro-agents into applications to identify threats. It works in companies such as ZipRecruiter, Le Monde, and BlaBlaCar real-time insights into an unusual activity and blocks attempt to infiltrate their software.

“Many strategic tasks are managed with an engineer-driven approach — performance, deployment, log monitoring, error management, but not security,” co-founder and CEO of Sqreen, Pierre Betouin said.

Application Security Management leverages micro-agents embedded in applications to identify and automatically protect against security threats in real time. With no software code modifications, Sqreen can run and protect any web application in a few minutes. Its hybrid SaaS architecture allows safe deployment through micro-agents, without redirecting traffic or installing complex on-premises software.
