Website Vulnerability Scanner

Scan type

Our custom-built Website Vulnerability Scanner detects SQLi, XSS, command injection, XXE, and 75+ more web app vulnerabilities, using strategically crafted test payloads to validate their exploitability.

Engineered to handle modern web app architectures, it efficiently crawls SPAs and other JavaScript-heavy websites, detects hidden API endpoints, and navigates complex authentication flows.

Export findings into customizable reports - complete with risk prioritization, actionable evidence (screenshots, attack replay, HTTP request/response), and clear remediation steps to speed up the fixes that make a difference.

Find exploitable web app vulnerabilities with documented evidence

Our proprietary Website Vulnerability Scanner gives security pros and appsec teams what they need: highly accurate, validated findings and actionable evidence - not just a long list of possible exposure points.

Unlike generic scanners that flag potential issues without context, our tool uses out-of-band detection to minimize false positives and ensure reliable results, collecting proof along the way.

Perform unauthenticated recon, deep authenticated testing, or automated compliance scans - all with a powerful, easy-to-use tool that blends into your workflow.

Simulate authenticated and unauthenticated attacks to uncover deeper security flaws, such as SSRF with access to an internal service, OS command injection, exposed credentials, and misconfigurations in SPAs, APIs, and traditional web apps.

The Website Vulnerability Scanner on Pentest-Tools.com mimics real attackers’ tactics and focuses on realistic, exploitable issues rather than ticking boxes.

We keep it sharp by battle-testing it every day in web app pentests that our offensive security services team performs.

Trust your results. Minimize FPs with proof-based validation illustration

Trust your results. Minimize FPs with proof-based validation

Our Website Vulnerability Scanner doesn’t just find web app security issues - it gives you the evidence you need to validate and report real security risks.

As it crawls and tests your web app, it captures payload execution results and collects evidence such as HTTP request/response with highlighted proof, screenshots, and extracted sensitive data. The scanner also uses out-of-band detection to find invisible vulnerabilities which don’t show up directly in the HTTP responses.

When it’s confident the vulnerabilities it found actually exist, the scanner’s automatic validation feature applies a "Confirmed" label. Where available, it also gives you an instant replay attack option.

Get deeper findings, faster. Even from JavaScript-heavy websites illustration

Get deeper findings, faster. Even from JavaScript-heavy websites

Our Website Vulnerability Scanner uses a powerful browser-based crawler to scan Single Page Applications (SPAs) and other JavaScript-heavy websites - fast and accurately.

Because it uses parallelization to detect cloud-hosted URLs, it speeds up discovery and attack surface mapping, giving you findings faster.

Scan results include deeper insights too, such as API endpoints detected during crawling, automated OpenAPI fuzzing, and improved detection for publicly accessible files and pages that should’ve been hidden.

This approach ensures comprehensive attack surface coverage and higher vulnerability detection rates.

The Website Vulnerability Scanner adapts to the complexity of the web apps you’re testing, offering flexible scan configurations to get precise results.

Adjust the spidering approach and depth and the number of requests per second to match your target's environment. You can even set custom scan times to make every second count.

The scanner also navigates complex authentication flows and uses session recording, form-based authentication, headers, and cookies to test behind login pages and detect vulnerabilities to which only authenticated users get exposed. Think CSRF, broken access controls, session misconfigurations, and 75+ more web app vulnerabilities.

How does the Website Vulnerability Scanner work?

The Website Vulnerability Scanner is a DAST (Dynamic Application Security Testing) tool designed to discover vulnerabilities like XSS, SQL injection, HTTP Prototype Pollution, Directory Traversal, and 75+ more vulnerabilities in running web applications.

The scanner interacts with the target application by sending numerous HTTP requests with specific payloads. If the application is vulnerable, these payloads will determine the code to behave abnormally, informing the scanner that a vulnerability exists.

Use this tool from your command line interface

If you prefer it, we also provide a CLI version of our Website Vulnerability Scanner. Through the Pentest-Tools.com CLI, you can run Light scans against your web apps and start gathering insights for your next move.

  • 1. Installation

    curl -s https://pentest-tools.com/cli-scan/linux/ptt.zip -o /tmp/ptt.zip
