Diffblue Cover analyzes your existing Java program and writes unit regression tests that reflect the current behavior of the code. The CLI tool works 100% autonomously, configuring itself from your Maven or Gradle environment. By bringing automation to the test-writing process, the CLI tool provides a speed boost for organizations that are working towards achieving DevOps goals like CI/CD. Since it fits into a CI pipeline, the CLI tool protects the whole codebase from regressions by shifting testing left. Diffblue Cover's unit regression tests run fast and verify new code changes immediately, helping users detect undesirable changes in the code’s behavior as early as possible, when they're the quickest, easiest, and cheapest to fix. And tests are automatically maintained, saving teams even more time.

P4 (formerly Helix Core) is an enterprise-grade version control system designed to manage the complexities of modern software development.

With strong support for both centralized and distributed workflows, P4 enhances productivity and efficiency, making it a top choice for software, game, and hardware development teams.

Codacy is an automated code review tool that helps identify issues through static code analysis, allowing engineering teams to save time in code reviews and tackle technical debt. Codacy integrates seamlessly into existing workflows on your Git provider, and also with Slack, JIRA, or using Webhooks. Users receive notifications on security issues, code coverage, code duplication, and code complexity in every commit and pull request along with advanced code metrics on the health of a project and team performance. The Codacy CLI enables running Codacy code analysis locally, so teams can see Codacy results without having to check their Git provider or the Codacy app. Codacy supports more than 30 coding languages and is available in free open-source, and enterprise versions (cloud and self-hosted).

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. The ActiveState platform centers on open source languages packaged as runtimes that can be deployed in various form factors. Low-to-no CVE container images are also available for plug-in and play needs.
