16 Pentest Tools To Help You Find Security Vulnerabilities in a Website

The internet has grown by leaps and bounds, but so have hacking activities. There is no point in denying that web apps and vulnerabilities go hand-in-hand. Despite existing web security vulnerabilities, we tend to pay more attention to SEO and website design.

In other words, we underestimate the security loopholes that exist in our websites and web apps. Just like the digital world, hacking techniques and tools have become more advanced. In order to find security vulnerabilities in your website, you have to opt for various types of pentest tools.

A Penetration testing service is used to detect and exploit vulnerabilities to gain insights that help us prioritize and fix the vulnerabilities. The primary objective behind these tests is to ascertain the severity of security issues with web applications.   

Why finding a vulnerability is important in a website?

Vulnerability analysis recognizes and lists all existing security breaches on your website. On the other hand, penetration testing emphasizes how each of these security breaches can be exploited. It is worth mentioning here that vulnerability testing uses both automated and manual ways.

There are tons of vulnerability scanners available on the web which assess your site’s overall security. The main reason to find security vulnerabilities in the website is to provide the user with a holistic view of security improvements needed on the website.

It also assists in preparing the security team to cope with a real-life cyber attack. So let’s take you through some of the most commonly used vulnerability and pen testing tools to identify web security loopholes.
