Acceptable use

Last updated 5 November 2026

Only test systems you own, or have written permission to test. Anything else is a crime under the Computer Misuse Act 1990 in the UK, and under similar laws in most countries.

What the Cyber Monk edition is for

Cyber Monk adds Kali Linux's top security tools and the Tor Browser, for people learning ethical hacking and cyber security. Before the tools install, you must confirm you'll use them lawfully.

Allowed

  • Testing your own devices, your own home network and your own websites.
  • Testing systems where the owner has given you written permission, with an agreed scope.
  • Practice labs built for it, such as TryHackMe and Hack The Box, within their rules.
  • Using Tor Browser for lawful privacy.

Not allowed

  • Scanning, probing or attacking any system you don't own and don't have written permission to test, including Wi-Fi networks, websites, school or work systems.
  • Getting into accounts, devices or data that aren't yours.
  • Disrupting services, spreading malware, or anything else illegal.

The law (UK)

The Computer Misuse Act 1990 makes it a criminal offence to access a computer without authorisation, to do so intending further offences, or to impair a computer's operation. Having the tools is legal. Using them without permission is not.

Our part

We provide the tools for learning and authorised testing. We won't help with anything unlawful, and we cooperate with lawful requests from the authorities.
