Website Vulnerability Scanner

Discover common web application vulnerabilities and server configuration issues

The Light version of the Website Vulnerability Scanner performs a passive web security scan to detect issues like: outdated server software, insecure HTTP headers, insecure cookie settings and a few others (see the complete list of tests below).
We recommend doing a Full Scan for a comprehensive website assessment which includes detection of SQL Injection, XSS, Local File Inclusion, OS Command Injection and more.

Website Vulnerability Scanner - Use Cases

Finds common vulnerabilities which affect web applications: SQL Injection, XSS, OS Command Injection, Directory Traversal, and others. The scanner also identifies specific web server configuration issues.

Website Penetration Testing

Speed-up your penetration test with this online scanner. It is already set-up and configured with the optimal settings for best results and performance. Just start the scan and come back later for results.

Self-Security Assessment

You can perform a self-security assessment to detect weaknesses in your own application. This will allow you to fix the vulnerabilities before being hit by real attackers.

Third-Party Website Audit

If you are a web development company, you can also show this report to your clients and prove that you have implemented the proper security measures in the application.

Technical Details


The Website Vulnerability Scanner is a custom tool written by our team to quickly assess the security of a web application. It is a full-blown web application scanner, capable of performing comprehensive security assessments against any type of web application.

The free scan that you can perform on this page is a Light Scan, while the Full Scan can only be used by paying customers. Here is the complete list of tests performed by this vulnerability scanner and the difference between Light and Full scans.

List of tests performed

Light Scan Full Scan Test performed
Fingerprint web server software
Analyze HTTP headers for security misconfiguration
Check the security of HTTP cookies
Check the SSL certificate of the server
Check if the server software is affected by known vulnerabilities
Analyze robots.txt for interesting URLs
Check whether a client access file exists, and if it contains a wildcard entry (clientaccesspolicy.xml, crossdomain.xml)
Discover server configuration problems such as Directory Listing
Check if HTTP TRACK/TRACE methods are enabled
Crawl website
Check for SQL Injection
Check for Cross-Site Scripting
Check for Local File Inclusion and Remote File Inclusion
Check for OS Command Injection
Check for outdated JavaScript libraries
Find administrative pages
Check for sensitive files (archives, backups, certificates, key stores) based on hostname and some common words
Attempt to find interesting files/functionality
Check for information disclosure issues
Weak Password Submission Method
Clear Text Submission of Credentials
Verify Domain Sources
Check for commented code/debug messages
Find Login Interfaces
Check for ASP Cookieless Cross-Site Scripting
Sensitive Data Crawl

Warning: The Full Scan generates a high amount of noise in the network. Most correctly configured IDSs will detect this scan as attack traffic. Do not use it if you don't have proper authorization from the target website owner.


Parameter Description
Target URL This is the URL of the website that will be scanned. The tool does not follow any redirects so the exact URL will be scanned. If you want to scan only a certain directory or path, you can add it in the URL like All URLs must start with http or https
Light Scan This is a fast, passive, and non-intrusive scan
Full Scan This is a complete assessment that covers a much broader range of security tests
Authentication - User/Password The credentials for the scanner to try authentication before starting the scan
Authentication - Cookie A valid session cookie that will be used by the scanner to do authenticated scans
Authentication - Headers Custom HTTP headers that can also be used for authentication (ex. JWT tokens, Basic Authentication, etc)

How it works

The Full version of the scanner includes all the tests from the Light scan and adds more complex security tests. It first crawls the target application then it sends various inputs into the parameters of the pages and looks for specific web vulnerabilities such as SQL Injection, Cross-Site Scripting, Local File Inclusion, OS Command Injection, and many more.
Furthermore, the scanner also attempts to detect sensitive files from the server like backup files, old files, admin interfaces, archive files, etc.

While the Light Scan is passive and generates a maximum of 20 HTTP requests to the server, the Full Scan is more aggressive and sends up to 10,000 HTTP requests. This may trigger alarms from IDS devices but you should know that it is not a destructive scan.

Since the Full Scan does a comprehensive website assessment, it can take up to several hours to complete.

Authenticated Scanning

The Website Vulnerability Scanner can scan the target web application as an authenticated user. The authentication can be configured in two ways:
  • User/Password Authentication: When this option is chosen, the scanner will first try to authenticate to the provided login URL and obtain a valid session cookie. This cookie will be used with all the HTTP requests done to the server, performing an authenticated scan. You have the option to check if the authentication was successful before actually starting the scan.
  • Cookie Authentication: With this option, you can specify an already valid session cookie (or multiple cookies) that will be sent with each HTTP request to the server. You have to first obtain the session cookie by manually logging in to your target application with a web browser and transferring the cookie from the browser to the scanner (copy/paste).
  • Headers Authentication: This option allows you to specify custom HTTP headers that will be sent with each request to the target application. These can be used for authentication (ex. JWT tokens, Basic Authentication, etc) or for other specific application functionality.
  • Recorded Authentication: This method gives you the possibility to record the steps required to authenticate into the target. The scanner will use this recording by replaying the actions and obtain a valid session every time it detects logging in again is required.
