Is he an employee coming to work?

Is he a vendor attending a proposal meeting?

Is he here to repair something?


It doesn't matter. In all cases, he was allowed on your premises for a legitimate purpose.


Unfortunately for you, he will plant three electronic eavesdropping devices, in strategic areas, before he leaves. It will only take seconds. You will never see it happen. You will never know. This is only one industrial espionage spy trick. There are hundreds more.


Savvy corporations, government agencies and organizations conduct periodic Technical Information Security Surveys, an enhanced version of the old Technical Surveillance Countermeasures (TSCM) bug sweeps. You should too.
