SAST tools are static application security testing tools that analyze source code to identify potential vulnerabilities and weaknesses, such as sensitive data exposure, SQL injection, and code injection. Conventional SAST tools have failed due to slow running times, embedding security in separate CI processes, creating false positives, and not providing actionable fixes for identified issues. Developer-first SAST tools, like Snyk Code, aim to increase developer productivity by integrating security into workflows, providing real-time feedback loops, high accuracy, low false positives, empowering developers to fix code security issues, and offering contextual information about suggested fixes. These features enable developers to find and address security issues directly in their tools, making secure coding a seamless part of their workflow.
