What Is the Online URL Scanner?
The online URL scanner checks if a website is safe to visit before you open it. Paste any link and it inspects the target for web threats, so you can also verify a link is safe to click before sharing it.
How to use it in two clicks: paste the full URL into the box above, then press Scan. No registration or installation is required, and results usually arrive within 30 to 60 seconds.
You get a readable report with HTTP security headers, SSL/TLS settings, content security analysis, and any detected vulnerabilities — free and without an account.
Scanning Principles
OWASP/CWE-Based Detection Engine
Use our free scanner to check your website for viruses, malware, and security vulnerabilities. A web vulnerability scanner works by sending safe test requests to your website and analyzing the responses. It checks for thousands of known vulnerability patterns from the CWE (Common Weakness Enumeration) database and tests against the OWASP Top 10 risk categories. This helps identify security gaps like injection flaws, broken authentication, and misconfigurations before real attackers can exploit them.
Common Vulnerability Types
- SQL Injection (SQLi) Detection
- Cross-Site Scripting (XSS) Exploits
- Broken Authentication Flaws
- Outdated Software Alerts
The scanner evaluates your site against OWASP Top 10 risk categories including SQL Injection (CWE-89), Cross-Site Scripting (CWE-79), and security misconfigurations (CWE-16). Each finding is cross-referenced with CWE identifiers for precise vulnerability classification and remediation guidance.
Detection Metrics & Risk Levels
Our scanner evaluates each detected issue using multiple criteria to provide a complete security picture:
- Severity scoring based on CVSS (Common Vulnerability Scoring System)
- CWE-standard vulnerability classification for precise identification
- OWASP-aligned risk assessment with remediation priority
The comprehensive report helps you understand which vulnerabilities pose the greatest risk and how to fix them efficiently.
Multiple Critical Security Indicators
- OWASP Critical Risks: Insecure Deserialization, XXE Attacks
- CWE Compliance Check: Server Misconfigurations (CWE-16), Weak Cryptography (CWE-327)
- Site Health Score: SSL/TLS validity, Security Headers (CSP/X-Content-Type)
- Malware Detection: Cryptojacking scripts, Phishing redirects
How to Use the Free Web Scanner
Whether you are a website owner checking your own site or someone who received a suspicious link, scanning a URL with our free web vulnerability scanner takes just three steps:
Enter URL
Paste the full website address or any URL you want to check into the scanner input field. The scanner accepts HTTP and HTTPS URLs for any publicly accessible page, domain, or web application.
Start Scan
Click the "Scan" button to start the security check. The scanner runs through hundreds of test cases — including SQL injection, XSS, CSRF, and security misconfiguration checks — and usually completes within 30 to 60 seconds depending on the target site.
Get Report
Once the scan finishes, you will see a detailed report with every vulnerability found, its severity level (critical, high, medium, low, or informational), the affected component, and clear remediation steps you can follow to fix each issue.
Unlike a basic link checker that only tests one thing at a time, our web scanner combines OWASP-based vulnerability detection, CWE pattern matching, and malware analysis in a single scan. The full report covers every threat category the scanner checks, with severity ratings and actionable fix guidance for each finding. To dig deeper into a domain, pair this scan with our whois lookup tool for registration details or the DNS lookup tool for record checks.

Frequently Asked Questions
A web vulnerability scanner is an automated tool that checks websites for security weaknesses such as SQL injection, cross-site scripting (XSS), and misconfigurations. You can use it to check any website for viruses, malware, and security flaws before attackers can exploit them.
Yes, our web scanner is completely free to use with no hidden costs or subscriptions. You can scan any publicly accessible website URL at no charge.
Our scanner detects a wide range of vulnerabilities including SQL Injection (SQLi), Cross-Site Scripting (XSS), CSRF, broken authentication, security header misconfigurations, and outdated software alerts following OWASP and CWE standards.
Most scans complete within 30 to 60 seconds, depending on the size and complexity of the target website. You will receive a detailed report once the scan finishes.
Yes. The URLs you submit are used only for the security scan and are not stored or shared with third parties. Your privacy is fully protected.
The scan report shows each detected vulnerability with its severity level (critical, high, medium, low), a description of the issue, and remediation recommendations to help you fix the problem.
No account is required. You can run a web vulnerability scan immediately by entering any public URL. Scans are anonymous and no registration is needed.
Our scanner only tests publicly accessible pages without authentication. Pages behind a login, intranet URLs, or sites requiring credentials cannot be scanned, since the scanner has no way to authenticate.
Our automated scanner quickly identifies common, known vulnerabilities using signature-based and heuristic checks. A full penetration test is performed by human security experts, includes manual exploitation, business-logic testing, and is more thorough but also more expensive and time-consuming.
We recommend scanning your website at least once per week, and immediately after any code change, new feature deployment, or third-party plugin update. Regular scanning helps you catch new vulnerabilities before attackers do.
Enter the full URL into the scanner above and press Scan. The report checks for malware, phishing signals, security header issues, and known vulnerabilities, so you can see whether a website is safe to visit before clicking through. It is completely free and requires no sign-up.
Yes. There is no account or registration required — paste any public URL and run the scan immediately. Scans are anonymous, and you can check unlimited URLs for free.
