Xygeni delivers a comprehensive Application Security Posture Management (ASPM) platform that secures software from code to cloud. Designed for enterprise security and DevSecOps teams, it provides full-stack protection across codebases, pipelines, and production environments—all from a single dashboard. Xygeni continuously monitors every layer of the SDLC, including source code, open-source dependencies, secrets, builds, IaC, containers, and CI/CD systems, detecting threats such as vulnerabilities, misconfigurations, and embedded malware in real time. Its AI-driven engine reduces alert fatigue by prioritizing exploitable risks and automating remediation through AI SAST, Auto-Fix, and the intelligent Xygeni Bot. Developers can fix issues instantly within their IDE, ensuring security is embedded from the first line of code. Advanced malware early warning blocks zero-day supply-chain attacks at publication, while smart dependency analysis prevents risky or breaking updates before deployment. With seamless integrations into leading DevOps tools, Xygeni empowers teams to secure modern applications at scale. The result: continuous protection, smarter automation, and faster, safer software delivery.

Enhance the quality of your code by adopting healthier coding practices and refining your code review process. Codecov offers a suite of integrated tools designed to organize, merge, archive, and compare coverage reports seamlessly. This service is free for open-source projects, with paid plans beginning at just $10 per user each month. It supports multiple programming languages, including Ruby, Python, C++, and JavaScript, and can be effortlessly integrated into any continuous integration (CI) workflow without the need for extensive setup. The platform features automatic merging of reports across all CI systems and languages into a unified document. Users can receive tailored status updates on various coverage metrics and review reports organized by project, folder, and test type, such as unit or integration tests. Additionally, detailed comments on the coverage reports are directly included in your pull requests. Committed to safeguarding your data and systems, Codecov holds SOC 2 Type II certification, which verifies that an independent third party has evaluated and confirmed their security practices. By utilizing these tools, teams can significantly increase code quality and streamline their development processes.

With VAddy, your development team doesn’t need to possess extensive knowledge in security matters. It simplifies the identification of vulnerabilities, enabling you to address them proactively before they become embedded in your codebase. Integrating seamlessly into your current CI workflow, VAddy operates automatically after each code alteration, notifying you whenever a commit introduces potential vulnerabilities. Many of us have experienced how a vulnerability discovered right before a project’s launch can derail timelines. By consistently conducting thorough security assessments throughout your development phases, VAddy helps mitigate those unexpected disruptions. Additionally, it provides insights into the occurrence of security vulnerabilities linked to specific team members or code modules. This capability allows for the prompt identification of areas needing improvement and fosters knowledge enhancement among developers who may lack strong security awareness. Our diagnostic engine is continuously refined and updated by seasoned security professionals to stay ahead of emerging threats. Consequently, your team can confidently build secure applications without requiring specialized security expertise. This results in a more efficient development process, leading to higher quality software delivery.

Every minute, a multitude of autonomously generated tests is executed to identify vulnerabilities and facilitate swift remediation. Mayhem eliminates uncertainty surrounding untested code by autonomously creating test suites that yield practical outcomes. There is no requirement to recompile the code, as Mayhem operates seamlessly with dockerized images. Its self-learning machine learning technology continuously executes thousands of tests each second, searching for crashes and defects, allowing developers to concentrate on enhancing features. Background continuous testing detects new defects and expands code coverage effectively. For each defect identified, Mayhem provides a detailed reproduction and backtrace, prioritizing them according to your risk assessment. Users can view all results, organized and prioritized based on immediate needs for fixes. Mayhem integrates effortlessly into your existing development tools and build pipeline, granting developers access to actionable insights regardless of the programming language or tools utilized by the team. This adaptability ensures that teams can maintain their workflow without disruption while enhancing their code quality.

Veracode provides a holistic and scalable solution to manage security risk across all your applications. Only one solution can provide visibility into the status of all types of testing, including manual penetration testing, SAST, DAST and SCA.
