The use of listening devices or "bugs" all sounds a little 1980’s Bondesque espionage, but it does happen and perhaps more often than you realise. Company sensitive information from board meetings down to team tactics in a changing room before a premier league match is just some of the things we have been asked to check. Bugs don’t have to just be listening devices, more sophisticated ones may also contain video but the more functionality means the bigger the size of the device and the less covert and effective it may be.
