Don't just sweep the room. Make it unbuggable.
Secure rooms engineered so surveillance fails by design — then proven by a sweep.
A sweep tells you the room is clean today. It says nothing about tomorrow. The highest-value spaces need surveillance to fail by design — not to be caught after the fact. We harden the space across four layers — signal, sound, emanation, and access — so the room protects the conversation whether or not anyone is watching for bugs.

The gap
A sweep is a moment. A conversation is a target every day.
Detection tells you the room is clean now. But the board meets every week, the devices come back through the door every morning, and the walls leak the same way they did yesterday. Three structural realities keep the room exposed between sweeps:
The shelf-life problem
A sweep is a verdict with an expiry date — the room is clean the moment the team leaves, and no longer. Between sweeps, the space is exactly as exposed as it was before.
The device you invited in
Every phone, laptop, and smart-TV in the room is a microphone and a radio. You can't sweep your way out of hardware your own people carry through the door each morning.
The wall that leaks
Sound travels through drywall and ducting; RF passes through glass; screens and cables emanate. A room that was never engineered to contain a conversation, doesn't.
The shift in thinking
Stop asking whether the room is bugged. Build a room where a bug doesn't work.
Signal can't get out — Shielding and denial contain every transmitter to the room
Sound can't be captured — Isolation and masking leave a recorder only noise
Emanations can't be read — TEMPEST-grade control keeps screens and cables silent
The wrong device can't get in — Access and device protocol make it a procedure, not a hope
The lifecycle
Detect. Harden. Protect.
Counter-surveillance is three moves, not one. A sweep finds what's there; hardening removes the possibility; persistent protection holds the line. This service is the middle — and the one that lasts.

Engineer the room so surveillance can't work in the first place.
The layers
Four layers. One silent room.
Surveillance has four ways in — radio, sound, emanation, and the door. Hardening closes all four, because a room is only as secure as the vector you forgot.
RF containment & denial
Stop wireless surveillance at the boundary. Shielding (Faraday-grade where required) contains signals inside the room; controlled denial — the M5P class of equipment — makes cellular, Wi-Fi, and covert transmitters unable to reach the outside.
Acoustic isolation & masking
Speech that can't leave the room can't be captured. Structural isolation stops sound conducting through walls and ducts; the GT series masks what remains, so any device that does record captures only unintelligible noise.
Emanation control (TEMPEST)
Screens, cables, and equipment leak compromising electromagnetic emanations that can be reconstructed from outside. TEMPEST-informed design contains them — filtered power, shielded AV, and disciplined cable routing.
Physical & access control
The strongest layers fail if the wrong person — or the wrong device — walks in. Hardened doors, mustering and device-check protocol, tamper-evident seals, and access logging make the room's security a procedure, not a hope.
Levels
Scaled to the room.
Not every space needs a vault. Hardening runs from a pragmatic uplift of a room you already use to an accredited, full-spectrum secure facility — matched to the threat, never oversold.
L1
Hardened meeting room
Acoustic masking, device discipline, and RF denial applied to an existing room — the pragmatic uplift for a space in regular use.
Boards & executives
L2
Secure conference facility
Purpose-engineered isolation, shielding, filtered power, and hardened AV — a room built to a defined and testable security level.
Listed companies & institutions
L3
Accredited secure room (SCIF-grade)
Full-spectrum containment to accreditation standard — RF, acoustic, and emanation control, with formal verification and sign-off.

How it's built
Assess. Design. Build. Verify.
A hardened room is engineered, not assembled — and it isn't finished until an independent sweep proves it performs.
Assess
Threat model, TEMPEST survey, and a construction read of the space — what leaks today, and what the conversations held there are worth.
Design
A secure-room specification engineered to a target level: the four layers, integrated, with the AV and access design drawn in from the start.
Build
Installation and integration by the team that designed it — shielding, acoustic treatment, denial, filtered power, hardened access, and secure conferencing.
Verify
An independent TSCM sweep proves the room performs to the level it was designed for — the same discipline that would try to beat it, confirming it can't.

Each layer specified to a testable target — then tested
Engineered to a target
Every layer specified to a defined, testable level — not 'more shielding' but attenuation to a number.
One accountable team
The team that designs the room installs it and verifies it — no seam between spec and delivery.
Proven, not promised
The build ends with an independent sweep. If it doesn't test to target, it isn't finished.
Designed to be silent. Tested to prove it.
Start with the space
Tell us the room. We'll tell you what it takes to silence it.
A discreet assessment reads the space, the threat, and the conversations it holds — then scopes the layers and the level your risk actually justifies. No vault you don't need; no gap you can't afford.
Build the program
Pairs well with
TSCM — Technical Surveillance Countermeasures
Hardening is verified by a sweep. Every build ends with an independent TSCM inspection that proves the room performs to the level it was designed for.
Secure Data Center Design
A secure room and a sovereign facility share a threat model. For whole-building programs, the two disciplines are designed as one.
FAQ
Common questions
Straight answers. If yours isn't here, ask us directly — discreetly.
Opposite directions. A sweep is detective — it inspects a space and finds devices that are already there, at a single point in time. This is preventive — it engineers the space so surveillance can't function: signals can't get out, sound can't be captured, emanations can't be read, and the wrong device can't get in. A sweep asks 'are we bugged right now?'; hardening asks 'can we build a room where being bugged doesn't work?' The two complete each other — and every hardening build ends with a sweep to prove it.
The safest room is the one built to be safe.
Sweep to know it's clean; harden to keep it that way. Four layers, one silent room, verified by the same discipline that would try to beat it. Start the quiet conversation.
