Penetration testing is important because-
Security breaches and loopholes in the systems can be very costly as the threat of attack is always possible and hackers can steal important data or even crash the system.
It is impossible to protect all the information all the time. Hackers always come with new techniques to steal important data and it is necessary for testers as well to perform periodical testing to detect the possible attacks.
Penetration testing identifies and protects a system by the above-mentioned attacks and helps organizations to keep their data safe.
