Other Terms That Apply to Your Use of the Website

Our Privacy Policy sets out the terms on which we process any personal information we may collect from you, or that you provide to us.

By using the Website, you consent to such processing and you warrant that all data provided by you is accurate.

Disclaimers

You agree that use of the Website is at your own risk.

In particular, you understand that:

  1. You are responsible for complying with applicable laws: We are not an application security scanning service and we do not endorse the use of application security scanning tools for unlawful means. You should ensure you adhere to all applicable laws and terms of service when using an application security scanning tool. Certain third-party content providers prohibit the use of application security tools to access their services and it is your responsibility to ensure that your use of any application security scanning services for any particular purpose is lawful.

  2. You should not rely on content presented on the Website: The content on the Website is provided for general information only. It is not intended to amount to technical, financial, or legal advice or any other type of advice on which you should rely. In particular, it does not constitute an invitation or authorization to use application security scanning tools for unlawful purposes nor does it constitute legal advice on the lawfulness of their use for any particular purpose.

  3. Information on the Website may be incomplete or out of date: Although we make reasonable efforts to update the information on the Website, we make no representations, warranties or guarantees, whether express or implied, that the content on the Website is accurate, complete or up to date. We are under no obligation to update information on the Website.

  4. We are not responsible for websites we link to: Where the Website contains links to other sites and resources provided by third parties, these links are provided for your information only. We have no control over the contents of those sites or resources.

  5. Independence disclaimer: appsecsanta.com is an independent comparison and review site. Reviews are editorially independent — no vendor pays, sponsors, or otherwise influences the rankings, placement, or assessments of any tool. Any commercial relationships the Website has (for example, affiliate links, sponsored placements, or paid partnerships) are disclosed on the pages where they apply and do not influence editorial decisions. The ordering and assessments of application security tools are based on our editorial evaluation criteria as described on our Methodology page. While we strive for objectivity, all reviews reflect editorial judgment and should not be treated as the sole basis for purchasing decisions.

  6. Age restriction: You must be at least 18 years of age to use this Website.

Free Security Tools — Acceptable Use

The Website offers free, browser-based security tools, including the Security Headers Checker, DNS Security Checker, SSL/TLS Checker, Subdomain Finder, and CSP Generator (the “Tools”). The Tools are provided as a convenience, “as is” and without warranty of any kind.

By using the Tools, you agree to the following:

  1. Authorization required: You will only submit domains, hostnames, or URLs that you own or that you have explicit written permission from the owner to test. Running unauthorized scans against third-party systems may violate the Computer Fraud and Abuse Act (in the US), the Computer Misuse Act (in the UK), Finnish criminal law, and equivalent legislation in other jurisdictions. You are solely responsible for ensuring your use of the Tools is lawful.

  2. No vulnerability testing: The Tools perform non-intrusive, read-only checks (HTTP headers, DNS lookups, TLS handshakes, Certificate Transparency queries). You must not attempt to use, extend, or combine the Tools to perform intrusive scans, exploitation, brute-force attempts, denial-of-service attacks, or any other activity that places load on or attempts to compromise a target system.

  3. Rate limiting and fair use: The Tools are rate-limited per IP address to prevent abuse. You must not attempt to circumvent rate limits, automate the Tools at scale, resell access, or integrate the Tools into your own commercial offering without written permission.

  4. No guarantee of accuracy: Results returned by the Tools are informational only. Grades, scores, and findings reflect automated checks against public data and may be incomplete, inaccurate, or out of date. The Tools are not a substitute for a professional security assessment, penetration test, or compliance audit, and results should not be relied upon as the sole basis for any security or compliance decision.

  5. No support obligation: We may modify, throttle, suspend, or withdraw any of the Tools at any time without notice.
