Perhaps it is not ideal, and you carry some expense and risk to yourself and the business by doing so, but in some organisations the constraints are so absurd that the competitive advantage you get by doing this and breaking the rules highly incentivises this. If the cyber security departments involved had any skin the game, or any sense of proportionality, then it would not be difficult to have a company issued laptop that also provides adequate security. But they don't, so developers like me end up having to make a tough decision. Break the rules, or work somewhere else.
