Modern software development must be as fast as the business. The modern AppSec toolbox lacks integration, which creates complexity that slows down software development life cycles. Contrast reduces the complexity that hinders today's development teams. Legacy AppSec uses a single-size-fits all approach to vulnerability detection and remediation that is inefficient, costly, and expensive. Contrast automatically applies the most efficient analysis and remediation technique, greatly improving efficiency and effectiveness. Separate AppSec tools can create silos that hinder the collection of actionable intelligence across an application attack surface. Contrast provides centralized observability, which is crucial for managing risks and capitalizing upon operational efficiencies. This is both for security and development teams. Contrast Scan is a pipeline native product that delivers the speed, accuracy and integration required for modern software development.

DerScanner is a user-friendly, officially CWE-Compatible tool that integrates the functionalities of static application security testing (SAST), dynamic application security testing (DAST), and software composition analysis (SCA) within a single platform. This solution significantly enhances oversight of application and information system security, allowing users to assess both proprietary and open-source code seamlessly. By correlating findings from SAST and DAST, it enables the verification and prioritization of vulnerability remediation. Users can bolster their code integrity by addressing weaknesses in both their own and third-party software components. Moreover, it facilitates an impartial code review process through application analysis that is independent of developers. This tool effectively identifies vulnerabilities and undocumented features throughout all phases of the software development lifecycle. Additionally, it allows for oversight of both in-house and external developers while ensuring the security of legacy applications. Ultimately, DerScanner aims to improve user experience by delivering a well-functioning and secure application that meets modern security demands. With its comprehensive approach, organizations can feel confident in their software's resilience against threats.
