I perform in-depth penetration testing across applications, networks, and infrastructure, simulating attacker techniques to uncover security flaws before real threats exploit them.
I execute adversary emulation to mimic advanced threat actors, testing not only technical defenses but also detection and response, delivering true resilience insights for organizations.
I analyze application source code line by line, identifying hidden security bugs, logic flaws, and insecure practices, ensuring software is secure, maintainable, and compliant.
Hi, my name is Shubham Chaskar, and I specialize in penetration testing, red teaming, and secure code review. With years of hands-on experience in cybersecurity, I focus on uncovering vulnerabilities before attackers do. My work goes beyond finding flaws, I help organizations strengthen their defenses, harden their infrastructure, and build resilience against evolving threats.
