SecureSMART Classifications (Highest – NATO Restricted)

Eavesdropping and industrial espionage does that really happen?

Unfortunately, the answer is – YES IT DOES – The damage to individual companies is often in the millions and more companies are being forced to take new countermeasures. Nowadays opponents neither are that charming like characters in movies nor do they have a face. Today companies are confronted with anonymous groups in “cyberspace”.

UNICUS will assist in the selection and integration of state-of-art solutions for secure communication.

Individually according to you or your organisations needs

whether smartphones via iOS iPhone, Android, Windows, BlackBerry or landline integration

we integrate across system boundaries.

the ultimate solution, from two individuals or for organisations requiring secure communications
