Terms & Conditions

Last updated: 20 June 2026

These Terms & Conditions (“Terms”) govern your use of df00tech.com (the “Service”), operated by DF00TECH LTD (“we”, “us”), a company registered in England and Wales (company no. 16185504), registered office 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ. By using the Service you agree to these Terms. If you do not agree, please do not use the Service.

The Service

df00tech provides a library of security detection content and related tools. All detection content — queries, response playbooks, investigation guides and atomic tests — is available free of charge to all users, with or without an account. The Detection Playground is in limited preview and is not generally available. We do not sell subscriptions or take payment for any part of the Service.

Accounts

An account is not required to use the Service. New registrations are currently closed. If you hold an existing account, you are responsible for keeping your credentials secure and for activity under your account, and for providing accurate information.

No charges

The Service is provided free of charge. There are no paid plans, subscriptions or in-service purchases, and we do not collect payment details. If we ever introduce a paid offering, it will be described here first and will not apply retroactively to content you have already downloaded.

Acceptable use

The Service and its content are provided to help defenders build detections. You agree not to:

  • use the Service for any unlawful purpose or to attack systems you are not authorised to test;
  • resell, redistribute, or republish the content except as permitted by the licence below;
  • attempt to disrupt, scrape at scale, or circumvent access controls of the Service.

Intellectual property & licence

The Service and its content are owned by df00tech or its licensors. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable licence to use the detection content within your own organisation for your internal security operations. Third-party marks (e.g. MITRE ATT&CK®) belong to their respective owners.

No warranty

The Service and its detection content are provided “as is”. Detections are aids for your security team and must be reviewed and tested in your own environment; we do not warrant that they will detect every threat or be free of false positives. To the extent permitted by law, we disclaim implied warranties.

Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect or consequential loss, or for loss arising from your reliance on the detection content. Nothing in these Terms excludes liability that cannot lawfully be excluded (such as for death or personal injury caused by negligence, or fraud). Your statutory rights as a consumer are unaffected.

Termination

You may stop using the Service at any time. We may suspend or terminate access if you breach these Terms. On termination, the licence granted to you ends.

Governing law

These Terms are governed by the laws of England and Wales, and disputes are subject to the courts of England and Wales, without affecting any mandatory consumer protections available to you locally.
