ICSL Consulting ↗

ICSL COMSEC · Innovation & Design

Your own devices. Built exclusively for you.

Developed for specific projects and requirements: devices designed and manufactured by ICSL exclusively to your specifications — from a single special feature to a fully proprietary device.

Custom Devices

When Standard Devices Are Not Enough

Some requirements cannot be met by any mass-produced device. For these cases, ICSL develops and manufactures devices exclusively for you — tailored to the intended use, threat landscape and security classification.

Reduced Hardware

Devices without cameras, microphones or unnecessary wireless interfaces — physically removed, not merely disabled in software.

TEMPEST Construction

Shielded construction against compromising emanations — to TEMPEST requirements on request.

Proprietary Manufacturing

Design and production exclusively for your project — not a mass-produced device from the open market.

Defined Functionality

Only the functions you actually need — everything else is omitted and cannot be attacked.

Controlled Supply Chain

Traceable components and integration — no undocumented parts, no open-market procurement.

Integrated with ICSL COMSEC

Custom devices work seamlessly with ICSL's secure communications infrastructure.

Process

From Requirement to Finished Device

Custom devices are developed for specific projects — from requirements analysis to delivery and maintenance. Data and designs remain confidential with ICSL.

Requirements gathering: intended use, threat model, classification and approval requirements.
Design: hardware and software concept with a minimal attack surface, aligned with your COMSEC environment.
Manufacturing: production exclusively for your project, with a controlled supply chain.
Integration & testing: independently evaluated interoperability with your secure communications.
Operations: maintenance, updates and lifecycle management throughout the service life.

Typical Starting Points

Three Situations Where a Standard Device Catalogue Cannot Help

Custom devices rarely begin with a request for a device — they begin with a requirement no off-the-shelf product can meet.

Minimalist device for secure communications — Reduced to the Essentials

The Situation Room

A room where a microphone must never operate unnoticed. The answer: devices with cameras and microphones physically absent, not just disabled in software.

The Field Operation

The mission requires exactly one wireless interface — every additional interface is a risk. So no others are installed.

The Special Requirement

A standard device would almost fit — except for one feature unavailable anywhere. ICSL develops and integrates it exclusively for you: from a single special feature to a fully proprietary device.

Why Hardware Matters

What is not installed cannot be attacked

Software can be reconfigured, bypassed or compromised — physically removed hardware cannot. That is why device security at ICSL begins with the design, not the app.

Every interface, sensor and wireless chip is a potential attack surface. A custom device contains only what the operation actually requires.
Procurement is part of the threat model: a controlled supply chain and documented components, rather than anonymous goods from the open market.
Even a device's unintentional emissions can reveal information — shielding to TEMPEST requirements is available on request.
Defined functionality also benefits the organisation: features a device does not have need no policy restrictions or monitoring.

Frequently Asked Questions

Brief Answers

Does it have to be a completely bespoke device?

No. Options range from a single special feature and targeted modifications (such as removing cameras or reducing interfaces) to a fully proprietary device designed and manufactured from scratch.

Will my secure communications run on it?

Yes. From the outset, custom devices are designed to work with ICSL's secure communications environment and tested together with it before delivery.

What does TEMPEST mean?

TEMPEST refers to requirements for devices protected against compromising emanations: electronics unintentionally emit electromagnetic signals from which information can be reconstructed. Shielded construction prevents precisely this.

How confidential will the project remain?

Requirements, designs and data remain with ICSL. Design and manufacturing are carried out exclusively for your project — discretion is a working principle at ICSL, not an additional promise.

How does a project like this work?

In five phases: requirements gathering, design, manufacturing, integration & testing, and operations throughout the service life — see the process above. It begins with a confidential briefing.

Need a device that does not exist yet?

Describe your requirements — we will confidentially assess what is feasible for your project.
