In today's fast-paced business environment, software development must keep pace with the demands of the market. However, the current AppSec toolbox often suffers from a lack of integration, leading to complexities that can impede the software development life cycle. By employing Contrast, development teams can alleviate these challenges, as it reduces the complications that frequently affect their productivity. Traditional AppSec methods rely on a one-size-fits-all strategy for identifying and addressing vulnerabilities, resulting in inefficiencies and high costs. In contrast, Contrast optimizes the application of the most effective analysis and remediation techniques, significantly enhancing both efficiency and effectiveness. Additionally, disparate AppSec tools can create operational silos, which obstruct the gathering of actionable insights related to the application's attack surface. Contrast addresses this issue by offering centralized observability, essential for risk management and leveraging operational efficiencies, benefiting both security and development teams alike. Furthermore, Contrast Scan, designed specifically for integration within development pipelines, ensures the swift, precise, and cohesive solutions that modern software development demands, ultimately leading to a more agile and responsive approach.

DerScanner is an intuitive, officially CWE-Compatible solution that combines the capabilities of static application security testing (SAST), dynamic application security testing (DAST), and software composition analysis (SCA) into a unified platform. This innovative tool greatly improves the management of application and information system security, enabling users to evaluate proprietary and open-source code with ease. By linking insights from both SAST and DAST, it facilitates the confirmation and prioritization of fixing vulnerabilities. Users can enhance the integrity of their code by addressing flaws in both their own and third-party software components. In addition, it promotes an unbiased code review process through analysis that is detached from the developers. The tool effectively uncovers vulnerabilities and undocumented features across all stages of the software development lifecycle. Furthermore, it provides oversight for both internal and external developers while safeguarding legacy applications. Ultimately, DerScanner is designed to elevate user experience by providing a secure and efficiently functioning application that aligns with current security standards.

Safeguard is an AI-powered application and software supply chain security platform designed to move security teams from vulnerability detection to automated remediation. The platform continuously inventories repositories, containers, software packages, dependencies, and other assets to create a live view of an organization's software environment. Griffin AI combines SBOM data, abstract syntax trees, call graphs, reachability analysis, exploit information, and business impact data to identify which vulnerabilities represent meaningful risk. Instead of generating a ticket for every finding, Safeguard can suppress unreachable issues and focus remediation efforts on vulnerabilities that can actually affect production systems. For actionable problems, its agents can author code changes or dependency upgrades, run automated testing, verify compatibility, and submit or merge pull requests under organization-defined policies. Safeguard also uses its Eagle adversarial model to search for zero-day vulnerabilities and test the validity of findings and proposed patches. Compliance capabilities automatically connect security activity and evidence to hundreds of frameworks while supporting SBOM formats such as CycloneDX and SPDX and recording SLSA provenance. The broader platform includes runtime defenses for AI systems, secure coding assistance, hardened zero-CVE packages and container images, Trust Centers, third-party risk management, and continuous security monitoring. Developers can work with Safeguard through IDEs, CLIs, source-control systems, CI/CD pipelines, cloud integrations, and more than 25 tenant-scoped MCP tools available to AI agents. Every automated action is designed to be logged, attributable, auditable, and governed by the same policies used throughout the platform.
