Free Website Security Scanner Tool by Get-Tools
Have you ever wondered how secure your website really is against cyber threats? The Get-Tools Website Security Scanner is a comprehensive analysis tool that examines your website from multiple security angles and identifies vulnerabilities and potential issues within seconds. This tool is completely free, requires no registration or subscription, and works with any publicly accessible website. Whether you are a website owner, a web developer, or a cybersecurity professional, this scanner provides everything you need to quickly and reliably assess the security posture of any website.
What Does the Scanner Check?
Security Headers
The scanner verifies the presence of essential HTTP security headers that form the first line of defense for any website. These include Content-Security-Policy (CSP), which prevents cross-site scripting (XSS) attacks and malicious code injection; Strict-Transport-Security (HSTS), which forces browsers to use encrypted HTTPS connections exclusively; X-Frame-Options, which protects against clickjacking attacks by preventing the site from being embedded in external frames; and X-Content-Type-Options, which stops browsers from incorrectly sniffing content types. The scanner also checks for Referrer-Policy, which controls information sent during page transitions, and Permissions-Policy, which manages browser permissions such as camera, microphone, and geolocation access.
SSL/HTTPS Certificate
The scanner checks whether the site uses the encrypted HTTPS protocol that protects data exchanged between the user and the server. It validates the SSL certificate, its expiration date, issuing authority, and the number of days remaining before expiry. Websites that do not use HTTPS expose user data -- including passwords, credit card information, and personal details -- to interception and theft. Moreover, search engines like Google give ranking preference to sites with valid HTTPS certificates, making it crucial for both security and SEO performance.
Exposed Files
The scanner searches for sensitive files that may be accidentally exposed on the server. These include environment files (.env) that often contain passwords, API keys, and database credentials; exposed Git directories (.git) that can leak the entire source code; database management pages like phpMyAdmin that may be accessible without authentication; backup files (.sql, .zip, .tar.gz); and other sensitive configuration files. Leaking any of these files could give attackers complete access to the system, leading to data breaches and server compromise.
Technology Detection
The scanner identifies technologies and frameworks used to build the website by analyzing HTTP headers and page content. It detects web servers like Apache and Nginx, programming languages like PHP, and content management systems like WordPress. Exposing specific software versions can help attackers target known vulnerabilities for those versions, which is why it is always recommended to hide version information from response headers.
Cookie Security
The scanner examines the security settings of cookies sent by the website. It checks for the Secure flag, which ensures cookies are only sent over HTTPS; the HttpOnly flag, which prevents JavaScript from accessing cookies and protects against session hijacking; and the SameSite attribute, which limits cross-site cookie transmission and guards against cross-site request forgery (CSRF) attacks.
Scoring System
The scanner assigns a score from 0 to 100 and a letter grade from A to F based on the comprehensive scan results. A grade of A (90 or above) means the website follows known security best practices. Grade B indicates minor improvements are needed. Grade C signals that important improvements are required. Grade D reveals vulnerabilities that must be addressed. Grade F indicates serious security issues requiring immediate intervention to protect the site and its visitors.
Practical Use Cases
For Website Owners and Businesses
Regularly scan your website to discover new security vulnerabilities and ensure best practices are applied. Run scans after every update or server configuration change. Periodic scanning helps maintain customer trust and protect personal data, and it can satisfy compliance requirements for data protection regulations.
For Developers and System Administrators
Verify security configurations after every deployment or server update. Confirm that no sensitive files have been leaked during the deployment process. Review security headers and ensure they are properly applied across all pages of the site. This tool integrates naturally into your deployment checklist.
For Cybersecurity Professionals
Perform a quick initial security assessment as the first step in a comprehensive security evaluation. Get a rapid overview of the security posture before diving into deeper penetration testing and vulnerability assessment.
Privacy and Safety
The scanner only examines publicly available information on the internet and never attempts to breach or exploit any discovered vulnerability. Scan results are not stored in our databases and are never shared with any third party. The scan is completely safe and has no impact on the performance or availability of the scanned website. All requests sent are standard read requests identical to what any browser sends when visiting the site.
Frequently Asked Questions
Does the scan harm the website?
Absolutely not. The scan only reads publicly available information and does not send any harmful data or attempt to exploit any vulnerability. It is essentially a normal visit to the site with inspection of the server responses.
Can I scan any website?
Yes, you can scan any website available on the internet. The scan uses only public information accessible to anyone through a standard web browser.
Are the results 100% accurate?
The scan covers the most important fundamental security checks and provides a clear picture of the overall security posture, but it does not replace a comprehensive, specialized security audit conducted by a cybersecurity expert.
How often should I scan my website?
It is recommended to scan your website at least once a month, and after every major update, server configuration change, or new release deployment.
