Contrast Runtime Security Platform

Stop attacks in your applications and APIs from development to production 

The modern application layer is too complex for legacy tools

Modern cyberattacks overwhelmingly target applications, APIs and open-source libraries—yet most security tools cannot observe their actual behavior. Traditional tools like WAFs and EDRs lack the full visibility and context to stop application-layer attacks and generate alerts, very few of which are exploitable. As a result, organizations are flying blind against the risks that matter most, unable to detect or prioritize real attacks.

Real-time, always-on security inside your applications and APIs

Contrast Security is the global leader in Application Detection and Response (ADR), empowering organizations to see and stop attacks on applications and APIs in real time. Contrast’s powerful runtime application security technology equips developers, AppSec and SecOps teams with one platform that proactively protects and defends applications and APIs against evolving threats. Armed with the right knowledge, security teams can identify exploitable issues and incidents in real-time, delivering a more accurate and actionable security posture than they could with legacy tools.
