JavaScript Vulnerability Scanner

What is an online JavaScript security scanner?

The JavaScript security scanner probes your web app and identifies weaknesses like Cross-Site Scripting, Cross-Site Request Forgery, Injection attacks, and more. The idea behind it is to effectively simulate a hacker attack by using automated and non-malicious analysis. This way, you can save on time and budget spent on penetration testing.

Additionally, it offers a continuous security approach by allowing you to run regular probes on your Staging system before you push to Production.

Note: It’s important that you own and have the permissions to set the JavaScript scanner. The JavaScript tool can generate different HTTP Requests that can be considered attacks (even if they are entirely inoffensive), so consider that you need the authorization to run this scanner.

How does the JavaScript security scanner work

The JavaScript scanner uses a web browser to execute the code. It automatically clicks on interactive elements and fills out form fields without requiring user input. It also scans the request detected during crawling (e.g., your REST API even if you have no documentation or specification for it).

In the end, it lists all findings in an extensive report, classifies them, and provides advice on how to fix them.

Why should I start a JavaScript vulnerability test?

JavaScript vulnerabilities are among the most commonly used by hackers to gain access to user and system data. Some of these security loopholes include Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF, XSRF), Server-Side JavaScript Injections, Clickjacking, and Client-Side Logic attacks according to the OWASP Top 10 vulnerabilities list in 2021.

And since XSS and CSRF are some of the most common hacker attacks, you should scan for vulnerabilities before every release. Companies aren’t aware of how expensive it could be to be under an attack. In fact, in the last years, massive attacks have occurred to small and medium companies, which are the ones that invest less money on their online security.

If you want to avoid hacking and make sure you are doing your best to protect your data and users, Js vulnerability scanner could help you reach your goals while focusing on your work. Waiting until the last moment to identify security loopholes is too risky and may impact your business goals.

How do I run a JavaScript test?

You will need to set up your scan target for the JavaScript scanner to verify and run a full scan. The scan’s duration is dependent on the size of your web application – the bigger, the longer it takes. But not to worry, move on with your day, and we will send you an email as soon as your scan is completed.
