Know Your Adversary

Who is Targeting Your Business or Home?

The truth is, eavesdroppers come from many walks of life. For example, an eavesdropper may be a competitor, an employee or a business colleague. Also, a company or executive residence may be targeted by a foreign national or foreign government. A reporter, private investigator or extortionist may target a hi profile individual. And, a spouse, ex-spouse or romantic interest may seek personal information. A neighbor may also target a private individual.

More specifically, eavesdroppers may be motivated by money, legal issues, emotions, fame, etc. But, they all want one thing – your valuable information!

Business Eavesdropping Targets

Unfortunately, businesses may be targeted for trade secret, confidential or sensitive information. For instance, competitors may want advanced knowledge of your sales strategy or contract negotiations. Likewise, a foreign national or nation may want to steal product or process information that will allow them to replicate it abroad. And, an activist group or a disgruntled employee may want to collect damaging information. Ultimately, a ComSec business bug sweep will help stop leaks of your trade secret and proprietary information. Click here for our corporate TSCM services page.

Residential Eavesdropping Targets

If you are an executive, your home or corporate apartment could be targeted for corporate information. Likewise, a former spouse or current romantic interest may target your home for personal information. Even politicians, celebrities and hi profile individuals may be targeted by tabloids, news reporters or profiteers. Why? Simply because private and damaging information is freely discussed in your home. In the final analysis, this is why a professional home bug sweep is important. Click here for residential TSCM services page.
