The risk:<\/b><\/h4>\n

Every electronic device unintentionally emits radiofrequency waves and conducted signals. A remote attacker can intercept these emissions to reconstruct critical data\u2014such as screen displays, keystrokes, and network traffic\u2014in real time. <\/p> <\/div>\n<\/div>\n\n

\n
\n

The Solution:<\/b><\/h4>\n

“Hardening” (or TEMPEST hardening) involves shielding the chassis to create a Faraday cage, adding filters to communication ports and the power supply, and using low-emission components.<\/p> <\/div>\n<\/div>\n\n

Equipment concerned:<\/b><\/h4>\n

Industrial Sovereignty: The Essonne facility<\/b><\/h4> <\/div>\n<\/div>\n <\/div>\n
\n <\/div>\n <\/div>\n \n
\n
\n

Until recently, France lacked an industrial player capable of locally manufacturing certified equipment. To address this gap, Logic Instrument, through its subsidiary Elexo, opened a TEMPEST production facility in Essonne. <\/p> <\/div>\n<\/div>\n

\n
\n \n
\n
\n
Made in France:<\/b><\/h5>\n

The facility enables the direct design or hardening of commercial off-the-shelf (COTS) equipment on national soil, ensuring a complete chain of trust.<\/p> <\/div>\n<\/div>\n\n

\n
\n
High-Security Infrastructure:<\/b><\/h5>\n

The site is a secure facility staffed by authorized personnel. It is equipped with a state-of-the-art semi-anechoic chamber for measuring residual electromagnetic leakage with extreme precision. <\/p> <\/div>\n<\/div>\n\n

\n
\n
Qualified Expertise:<\/b><\/h5>\n

The teams are specifically trained by leading experts, and the plant operates in accordance with ISO 17025 certification.<\/p> <\/div>\n<\/div>\n <\/div>\n

Strategic Partnership and NATO Certifications<\/b><\/h4> <\/div>\n<\/div>\n\n
\n
\n

Elexo has structured its product offering through a licensing agreement with Eurotempest, a European leader in the field. This partnership enables the company to offer products that meet the most stringent standards set by NATO (SDIP-27 and SDIP-55) and the Council of the European Union. <\/p>\n

The offering comes in three levels of protection tailored to the terrain’s risk level:<\/p> <\/div>\n<\/div>\n

\n
\n \n
\n
\n \"FULL <\/div>\n \n
\n
\n

FULL \/ SDIP-27 Level A <\/h4>\n \n
\n Maximum protection for areas where an intruder could be in the immediate vicinity (adjacent room). <\/div>\n <\/div>\n \n \n <\/div>\n \n<\/div>\n\n\n
\n
\n \"IMMEDIATE <\/div>\n \n
\n
\n

IMMEDIATE \/ SDIP-27 Level B <\/h4>\n \n
\n For environments where the attacker is kept at a distance of at least 20 meters. <\/div>\n <\/div>\n \n \n <\/div>\n \n<\/div>\n\n\n
\n
\n \"TACTICAL <\/div>\n \n
\n
\n

TACTICAL \/ SDIP-27 Level C<\/h4>\n \n
\n Intended for areas where physical safety prevents any approach within 100 meters. <\/div>\n <\/div>\n \n \n <\/div>\n \n<\/div>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

This project aligns with a national drive for technological independence. It is supported by the DGA and BPI-Definvest, which have granted a strategic loan of \u20ac1 million for the installation of radio-frequency testing equipment. <\/p> <\/div>\n<\/div>\n\n

\n
\n

Target Clients: In addition to the Ministry of the Armed Forces (notably via the MASTOC framework contract with DIRISI), Elexo serves intelligence agencies, critical infrastructure operators (OIVs), and major public institutions.<\/p> <\/div>\n<\/div>\n\n

\n
\n

Group Synergies: This business activity makes the Logic Instrument Group a unique end-to-end integrator, capable of providing ruggedized hardware, test and measurement solutions (via Distrame), and high-level electromagnetic security.<\/p> <\/div>\n<\/div>\n <\/div>\n
