Agentic AI pentesting is transforming security by moving beyond traditional, point-in-time assessments to continuous, autonomous attack simulation. It can map attack surfaces, chain vulnerabilities, and validate real risks at scale. While it won't replace human pentesters, it will amplify their capabilities, enabling faster, deeper, and more effective security testing.

Why big tech interviewers are tired of seeing the exact same blueprint, and how to fix it in 60 seconds.

The Software Testing Life Cycle (STLC) is a structured process that helps teams ensure software quality through different testing phases such as requirement analysis, test planning, test case development, environment setup, test execution, and test closure. It enables organizations to identify defects early, improve test coverage, and deliver stable applications with greater confidence.
