How is the security check of software products carried out before their release?

Security testing of software products before release includes several stages:

• Static code analysis — automatic detection of vulnerabilities and errors in the source code without executing it.
• Dynamic testing — testing the application during its operation, including penetration testing.
• Dependency analysis — checking used libraries and components for known vulnerabilities.
• Code review — manual inspection of code by experienced developers to identify potential issues.
• Use of automated security tools (SAST, DAST) — integration into CI/CD pipelines for continuous monitoring.

For example, in CI/CD, a step can be added to run a security scanner that checks the code and dependencies, and if critical vulnerabilities are found, the build will be interrupted.
