Flawnter helps automate static application security testing to find hidden security and quality bugs at the source. While traditional manual code review is great, Flawnter can help speed up this process while finding bugs you may have missed. Create your own custom Flawnter extensions or download existing ones. Extensions help expand your coverage of the testing to find more bugs. Extensions are easy to implement and gives you access to Flawnter functionality. Flawnter offers simple and flexible pricing that is affordable for any size of organization to improve their application code security and quality. The licensing is based on per user per year but other options are available.

Dependabot is an automated dependency management tool that integrates seamlessly with GitHub repositories to keep project dependencies up-to-date and secure. By regularly scanning for outdated or vulnerable libraries, Dependabot proactively generates pull requests to update these dependencies, ensuring that projects remain secure and compatible with the latest releases. Its core logic is designed to handle various package managers and ecosystems, making it versatile for diverse development environments. Developers can customize Dependabot's behavior through configuration files, allowing for tailored update schedules and specific dependency rules. By automating the dependency update process, Dependabot reduces the manual effort required to maintain project dependencies, thereby enhancing overall code quality and security.

Thousands of autonomously generated tests run every minute to pinpoint vulnerabilities and guide rapid remediation. Mayhem takes the guesswork out of untested code by autonomously generating test suites that produce actionable results. No need to recompile the code, since Mayhem works with dockerized images. Self-learning ML continually runs thousands of tests per second probing for crashes and defects, so developers can focus on features. Continuous testing runs in the background to surface new defects and increase code coverage. Mayhem delivers a copy/paste reproduction and backtrace for every defect, then prioritizes them based on your risk. See all the results, duplicated and prioritized by what you need to fix now. Mayhem fits into your existing build pipeline and development tools, putting actionable results at your developers' fingertips. No matter what language or tools your team uses.

Bugbot is an AI-powered code review agent that automatically reviews pull requests to identify bugs, security issues, and code quality problems. Built into the Cursor ecosystem, Bugbot analyzes PR diffs and leaves contextual comments with clear explanations and fix suggestions. It runs automatically on every pull request update or can be triggered manually using comments. Bugbot reads existing PR discussions to avoid duplicate feedback and build on prior context. The tool supports customizable rules through configuration files and team-wide policies to enforce coding standards. Bugbot integrates seamlessly with GitHub, GitLab, and enterprise repositories. It helps development teams catch issues early and improve code quality without slowing down workflows.

Claude Code Security is a new cybersecurity capability built into Claude Code that helps teams identify and fix software vulnerabilities. It scans entire codebases using AI reasoning rather than relying solely on traditional rule-based detection methods. The system analyzes how components interact and how data flows through applications to uncover complex, context-dependent security flaws. Each potential vulnerability undergoes a multi-stage verification process to reduce false positives and ensure accuracy. Findings are assigned severity and confidence ratings, allowing teams to prioritize the most critical risks. The platform suggests targeted software patches, but all fixes require human approval before implementation. Currently available in a limited research preview for Enterprise and Team customers, Claude Code Security is designed to strengthen defenses against AI-enabled cyber threats.
