Modern TSCM

Turning confidentiality into a repeatable process

Where information has value—boardrooms, M&A, R&D—eavesdropping risk grows. From covert transmitters and devices to manipulated wireless/optical paths, attacks are real. Effective defense blends technical inspections with operating rules—on a routine, documented basis.

Who should care?

C-suite and boards, security leaders, family offices, and teams in sensitive sectors (energy, healthcare, semiconductors, defense industry).

What TSCM means at ISN

TSCM (Technical Surveillance Counter Measures) is a multi-method program: radio-spectrum surveys, room/device inspections and defensible reporting—embedded in governance, staff training and practical “no-device” policies. Goal: detect devices, close gaps, institutionalize routine.

Technical measures (selected)

Broadband spectrum analysis

into high GHz bands to detect/localize suspect emissions.

Thermography / X-ray (case-by-case)

to verify concealed components.

Non-linear junction detection (NLJD)

to find electronics even when powered off.

Optical / IR checks

for line-of-sight and laser threats; plan shielding/attenuation where needed.

Endoscopic / visual inspections

of cavities, fixtures, outlets, IT peripherals and furniture.

Wired-network tests

in IT/telecom lines; optional sealing of inspected items.

Program, not a one-off: One-time “deep cleans” fade. Sustained protection is a cadence of assessment, inspection and aftercare, tuned to sites, usage and event rhythm.

How ISN delivers — a four-step model:

1. Assess

confidential scoping, risk screen (rooms, routines, travel), inspection plan.

2. Inspect

TSCM deployment with dual control, chain of custody, photographic and measurement records.

3. Harden

report with immediate fixes and a mid-term roadmap (e.g., shielding, device policies).

4. Monitor

cadence, ad-hoc checks pre-deal, micro-trainings for executive support staff.

Why ISN?

ISO quality management, global footprint, in-house academy

Multilingual, mobile teams with international experience

End-to-end security: TSCM plus executive protection, travel security and investigations

60-second self-check

Confidential rooms

Do you have “clean” rooms and pre-meeting releases for sensitive sessions?

Routine

Are critical spaces on a scheduled TSCM cadence with defensible reporting?

Simple rules

Are guest/vendor access, loaner/conference tech and interpreters governed by clear SOPs?

FAQs

How quickly can ISN perform checks?

From express assessments to on-site inspections – often planned at short notice, depending on the scope.

Do inspections disrupt operations?

We work discreetly and with a keen sense of urgency; critical meetings can be approved ‘just in time’.

Do we need TSCM despite NDAs/confidentiality agreements?

Yes – technology and governance close gaps that policies alone cannot prevent.
