Online Scanner Ranking: How to Find Out Your Site’s Vulnerabilities Before Hackers Do It

The virtual world is no less dangerous than the real one. It also has its share of thefts, attacks and hacks, which almost every developer, owner and sometimes even the average user of websites faces.

Since any security incident damages the reputation and rating of the website and also entails the loss of traffic or a decrease in income, cybersecurity is a priority for the business.

How to secure a website quickly and easily? How to find out in advance how vulnerable it is? Can it be easily hacked? What if it’s already hacked?

We did our best to answer the above-mentioned questions in this article by reviewing, comparing, and rating 23 website security inspection and analysis tools that are relevant in 2023.

An Overview of Website Security Assessment Services

The purpose of our review is to determine the optimal scanners for a quick assessment of website security by non-security experts.

Below are online web vulnerability scanners, so you don’t have to install any software to use them. We divided all scanners into two categories:
