What is VAPT?

Vulnerability Assessment and Penetration Testing (VAPT) is a comprehensive approach to identifying, analyzing, and addressing security vulnerabilities within your IT environment. It is a crucial part of any organization’s cybersecurity strategy, ensuring systems, networks and applications are secure from potential threats.

VAPT combines two key processes:

  • Vulnerability Assessment focuses on scanning systems to detect known vulnerabilities, misconfigurations, and weaknesses using automated tools.
  • Penetration Testing goes a step further by simulating real-world cyberattacks to exploit those vulnerabilities and assess the impact of a potential breach.

Together, these processes provide a detailed view of your organization’s security posture and actionable insights to strengthen defenses. VAPT helps businesses stay compliant with industry standards, avoid data breaches, and build customer trust through proactive risk management.
