    Contrast Security

    Contrast Security

    Contrast Security

    Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

    ActiveState delivers Intelligent Remediation for vulnerability management, which enables DevSecOps teams to not only identify vulnerabilities in open source packages, but also to automatically prioritize, remediate, and deploy fixes into production without breaking changes, ensuring that applications are truly secured. Existing tools overwhelm DevSecOps teams with excessive vulnerability data, false positives, and a lack of prioritization, often leading to inaction and increased exposure to exploits. ActiveState’s solution provides your DevSecOps with a comprehensive view of open source vulnerability status across your application portfolio, enabling them to prioritize the vulnerabilities that matter, assess the risk of updates, and choose recommended remediation paths based on corporate policies and avoiding breaking changes. We do this by helping you understand your vulnerability blast radius, intelligently prioritize remediations, and precisely remediate what matters.
