The one rule. Testing is legal only with the owner's authorisation, because US and UK computer misuse laws turn on it. So Cipher Bridge tests only systems you own or are explicitly authorised to test.

Learn it or hire it

Learn and hire guides for ethical hacking

These learn and hire guides split the subject in two, like the rest of this site. So each one answers a single question, and none of them is padded with hype.

Learn and hire guides: learn, practise or hire

The one rule in every guide

Testing is legal only with the owner's authorisation. US and UK computer misuse laws both turn on it. Therefore all the learn and hire guides start from that line, whether they teach or sell.

How to use these learn and hire guides

If you are learning, start with the lessons guide. Then build a lab, and practise on invited targets. Also, read the hat label guides, because they show where the legal line sits. If you are hiring, go straight to the services guide. It explains the scope, the authorisation and the fixed fee. So one message is usually enough to start. In short, the learn and hire guides save you a round of questions.
