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.

RapidFort streamlines the process of software deployment by automatically removing unnecessary components, resulting in more efficient, compact, and secure workloads. This innovative solution significantly cuts down on vulnerability management and patching tasks, allowing developers to concentrate on creating new features. By analyzing container setups, RapidFort determines essential components needed for operation, thereby bolstering the security of production workloads while sparing developers from the burden of managing irrelevant code. Users can deploy their containers seamlessly across various environments—be it development, testing, or production—and utilize any container orchestration tool, such as Kubernetes or Docker Compose. After profiling the containers, RapidFort highlights the packages that are necessary, facilitating the removal of those that are superfluous. Typical efficiency gains can range from 60% to 90%. Additionally, RapidFort offers users the flexibility to create and tailor remediation profiles, allowing them to selectively decide what components to keep or discard, further enhancing the customization and security of their deployments. This comprehensive approach not only simplifies management but also empowers teams to optimize their resources effectively.

The Code Registry is an innovative platform that harnesses AI for code intelligence and analysis, providing companies and non-technical users with complete insight into their software codebase, regardless of their coding experience. By linking your code repository—such as GitHub, GitLab, Bitbucket, or Azure DevOps—or by uploading a compressed archive, the platform establishes a secure "IP Vault" and conducts an extensive automated evaluation of the entire codebase. This analysis generates various reports and dashboards that include a code-complexity score to assess the intricacy and maintainability of the code, an open-source component evaluation that identifies dependencies, licensing issues, and outdated or vulnerable libraries, as well as a security assessment that pinpoints potential vulnerabilities, insecure configurations, or risky dependencies. Additionally, it provides a “cost-to-replicate” valuation, which estimates the resources and effort required to recreate or substitute the software entirely. Ultimately, the platform equips users with the necessary tools to enhance their understanding of code quality and security, thereby fostering more informed decision-making in software development.
