Website Vulnerability Scanner in the Webp toolkit is an easy-to-use, high-level vulnerability scanner that allows you to check basic aspects of website security, such as security headers, correct HTTPS configuration, the presence of typical error messages and potential signs of vulnerability to reflected XSS or error based SQL injection, without the need to install specialized tools on your computer.
Instead of manually analyzing HTTP headers in the browser console, testing various parameters in the URL and looking for error messages in the code of the page, you can simply paste the address of your application into Website Vulnerability Scanner in Webp, select the scanning modules you are interested in, click the scan application button, and after a while you will receive a clear report with an HTTP summary, a list of detected problems and modules that show in a simple way, where it is worth making configuration corrections or asking the development team for additional code review.
What Website Vulnerability Scanner in Webp can do and when you should use it
Website Vulnerability Scanner in Webp has been designed as a fast, user-friendly vulnerability scanner that can be used before publishing a new version of the application, after migrating to another server, after implementing an HTTPS certificate, or simply when you want basic confirmation that your website does not send random error messages in response, does not reveal unnecessary information about the server and uses recommended security headers. The tool does not replace dedicated security platforms, but it is a very good first step that helps detect typical, frequently encountered configuration problems.
Top Uses of Website Vulnerability Scanner
- An initial security check before a marketing campaign when you don't want to send a lot of traffic to a site that may have simple HTTPS configuration or security header issues.
- A quick check after deploying a new version of the application to see if there are any error messages, stack traces, directory listings, or other information that should not be seen by a regular user.
- Check whether your site uses recommended headers, such as those that limit the execution of unexpected scripts, block content from being embedded in unwanted frames, or support HSTS policies.
- Check for simple scenarios with URL parameters, when you want to see if the application is encoding data correctly and not returning it in a response in a way that may suggest potential problems with the reflected user data.
Who was Website Vulnerability Scanner created for
- For owners of websites and online stores who want to easily check basic security aspects, without having to read complex technical documentation.
- For people responsible for marketing or product who need quick information whether a new campaign is driving traffic to a website with obvious HTTPS problems or error messages.
- For developers and administrators who want to have a lightweight tool at hand for quick reconnaissance after implementing a new version, before starting more advanced tests using professional security platforms.
How to work with Website Vulnerability Scanner in Webp step by step
The Website Vulnerability Scanner interface is deliberately simple and based on one form with the most important settings, thanks to which the first scan can be performed literally in a few seconds, and at the same time the user retains control over such elements as redirection tracking, response time limit or which analysis modules are to be launched.
- You paste the full address of your application into theApplication URLfield, for example the page with the parameters you want to submit to a simple security test.
- You decide whether Website Vulnerability Scanner shouldfollowredirects, which is important for sites that redirect from http to https or use other transitions.
- You set atimeout for therequest so that the tool doesn't wait too long for a response when the server is overloaded or a given address is down.
- In the modules section, select whether you want to checksecurity headers and HTTPS configuration, run a simple parameter reflection test (reflected XSS), a basic test of the application's behavior with unusual data in the context of SQL errors, and a module for detecting error messages and potential misconfiguration.
- If you are testing an address with a parameter, you can specifythe name of the test parameter, which Website Vulnerability Scanner will use when building requests as part of simple modular tests.
- Finally, you click theScan Applicationbutton and wait until the tool finishes the analysis and displays a report with an HTTP summary, a list of issues and details for each module.
Website Vulnerability Scanner modules - what exactly do they check?
Website Vulnerability Scanner in Webp consists of several modules that can be turned on and off depending on your needs. Each module focuses on a different area of application security and presents the result in a simple way, with a description of the category, suggested severity and a short comment that helps understand the meaning of the detected observation.
Security Headers and HTTP/HTTPS Configuration
This module analyzes HTTP response headers to detect missing elements that are commonly recommended by specialists for protecting web applications, such as headers related to content policy, frame restriction, MIME type control, and referrer policy. Website Vulnerability Scanner flags missing headers as a potential problem and adds them to the list of identified issues, which allows developers or administrators to later improve server or application configuration.
- Indicates which security headers appear to be missing in the server response being examined.
- Tells whether the application responds via http or https, and suggests enforcing a secure protocol where possible.
- Signals headers that reveal detailed information about technology and software versions, which can be useful when organizing information exposure to the outside world.
Reflected XSS and basic SQL error checks
The reflected user data and simple SQL error checks modules check how the application responds to non-standard data that Website Vulnerability Scanner places in the test parameter. The goal is not to perform an advanced attack, but to check that parameters are not returned in the response without sufficient processing or that the application does not visibly generate database-related error messages when it encounters an unusual string of characters.
- The Reflected XSS module checks whether a test parameter is referenced in the response body in a way that may indicate a lack of full encoding of user data.
- Error based SQLi check observes whether unusual data in a parameter causes the page to display messages that resemble database errors, such as query, table, or SQL structure information.
- Module results are presented in text, emphasizing that this is only a quick first-level test that may suggest the need for a more thorough review of the code and data validation logic.
Error Messages, Mis Configuration, and Directory Listings
The final module focuses on detecting common signs of application or server misconfiguration, such as raw error messages, stack trace fragments, detailed environment information, and classic directory listings that show the contents of folders instead of the actual page. These types of elements should not usually be visible to an ordinary user, and their presence may be a signal that it is worth refining the configuration of the production environment.
- The scanner looks for known text fragments characteristic of error messages and traces in various popular technologies.
- Notes pages like index of or directory listing, which may show files in a directory instead of the target application view.
- Helps catch situations where the production environment is behaving like a development environment by displaying too much internal detail in the HTTP response.
How to read the report from Website Vulnerability Scanner and what to do next
After the scan, Website Vulnerability Scanner displays an HTTP summary with information about the final URL, server IP address, response status and the detected connection form (http or https), and below it a table with identified problems, where each item is assigned a category, severity level and a short description. Additionally, separate modules show a summary of security headers, a module of reflected user data, simple SQL errors, error messages, and a snippet of raw headers and response bodies so you can see the context.
| Report element | What does | mean in practice How can you use it |
|---|---|---|
| HTTP summary | Collective data about the response status, the http or https protocol and the IP of the server that handled the request. | Helps you quickly detect, for example, the absence of forced HTTPS or unexpected redirects to another host. |
| List of issues | Summary of detected issues divided into category, severity and description. | It can be used as a mini backlog of tasks for the development team or administrators responsible for configuration. |
| Security Headers Details | Tells which headers are present and which appear to be missing in the server's response. | Based on this, you can plan to implement additional security policies or improve the existing configuration. |
| XSS and SQL error modules | Will show whether simple parameter tests yield signals that user data is being sent back without full security or that the application is responding with database error messages. | If the report suggests a problem, it's worth asking the development team for more thorough testing and code fixes. |
| Raw Headers and Body Snippet | Displays a snippet of the original response so you can see the exact context of the issues detected. | This makes communication with the technical team easier because you can provide them with specific headers and an HTML fragment for analysis. |
Frequently asked questions about Website Vulnerability Scanner in Webp
Is Website Vulnerability Scanner free and available from the browser
Website Vulnerability Scanner works directly in the Webp toolkit, in a regular web browser, so you do not need to install additional software on your computer and can run a quick test on any device with Internet access. You can always find the current terms of use on the Webp website, but the scanner mechanism itself is designed for maximum ease of use and a low entry barrier.
Does Website Vulnerability Scanner replace a professional security audit
No, Website Vulnerability Scanner is a tool for quick, superficial analysis that is intended to help detect typical configuration problems and symptoms of security problems that are visible at first glance. A full security audit and penetration tests should be conducted by specialists, using advanced tools and a defined scope of tests and the degree of interference in the application.
Can I scan any websites
From the point of view of good security practices and regulations of many service providers, you should scan only those systems and applications to which you have the right to access or formal consent to testing, therefore use Website Vulnerability Scanner primarily to analyze your own company websites, stores, customer panels and other applications that you manage or are responsible for.
How often should you run Website Vulnerability Scanner on your website
It is a good practice to run a basic scan after any major change in the application, after migration to another server, or after making significant changes to the HTTPS configuration and security headers. Many people also use this tool periodically, for example once a month, as part of a simple, internal security checklist of their websites.
What to do if Website Vulnerability Scanner detects problems
The Website Vulnerability Scanner report should be treated as a list of tasks to be reviewed by technical people, for example backend developers, server administrators or an external security team. In practice, the best approach is to combine scanner results with a review of logs, server configuration, and application functional tests, and then gradually remove the highest-impact issues, starting with issues related to HTTPS, security headers, and error message visibility.
