For family offices, the attack surface extends across the family.

The principal is briefed and careful. The exposure is everywhere else: children's devices and socials, household staff, travel patterns, the assistant with calendar access, the shared systems nobody owns.

NSI Global’s protection programs treat the household as part of the security perimeter—bringing together devices, identities, communications, staff protocols and physical spaces within one discreet, coordinated program.

Quietly managed for the people who should not have to manage it themselves.

Counterintelligence isn't a product. It's a posture.

It's the difference between reacting to what happened and denying the opportunity in the first place.

Every capability NSI brings together — technical surveillance countermeasures, digital forensics and incident response, risk advisory and intelligence — serves that posture.

Deny the opportunity.

By the time most businesses suspect they're being listened to, the conversation they were worried about has already left the room.

Corporate rarely announces itself. A tiny device, left in a boardroom or an executive's office, can quietly sit through months of strategy, deals, disputes and privileged discussion. The people who plant them are counting on one thing: that you'll never think to check.

A professional TSCM sweep accounts for all of it. We inspect the spaces where sensitive conversations actually happen — boardrooms, executive offices, meeting rooms, vehicles — and check for illegal surveillance devices, external listening threats, and cellular and digital vulnerabilities, along with the gaps that let them in. Discreetly, and without disrupting your day.

If a deal, a dispute or a leak has you wondering whether the room is really private, that's the moment to act.
