What is pentest?

Pretend you have a toy castle with walls and gates. A "pentest" is like having a friendly superhero check your castle for weak spots, like loose bricks or open gates. They tell you where the weak spots are so you can fix them, keeping your castle safe and secure!

Pentest remediation refers to the process of correcting and securing vulnerabilities found in a penetration test, often involving fixing software bugs, updating systems, and strengthening security policies.
