EXOSFER

What EXOSFER does

Exosfer SAS, founded in 2017 and headquartered in Trappes, France, designs and sells mechanical and electronic anti-theft solutions for passenger vehicles and light commercial fleets. The company was established by Stéphane Boutonnet after his own Renault Clio 3 RS was stolen via electronic hacking, with the product portfolio explicitly targeting modern attack vectors including OBD port reprogramming and keyless entry relay attacks — methods the company notes account for nine out of ten vehicle thefts in France.

The product range comprises four SKUs: two mechanical deterrents (Bloque Volant steering lock and Bloque Pédale pedal lock at €29.90 each) and two electronic-protection devices (WAVE Protect RFID-blocking pouch using patented anti-wave fabric at €11.99–€12.49, and OBD Protect, a proprietary OBD-port wiring-modification system at €99.00 that requires professional installation). OBD Protect relies on vehicle-specific wiring plans and a proprietary adapter that restores OBD functionality for diagnostics, while WAVE Protect blocks all incoming and outgoing electromagnetic signals to and from key fobs.

The business operates a one-time-purchase revenue model with no subscription component. Sales are generated through three channels: direct-to-consumer e-commerce via exosfer.fr (with free pan-European shipping on orders above €100), a dedicated B2B professional portal (Espace PRO) serving fleet managers and commercial operators with bulk pricing and a downloadable brochure, and a France-based network of approved and trained garage partners that handle installations requiring technical expertise. Customers are primarily individual vehicle owners, with secondary segments of small fleet operators and installation partners; payment processing runs on Stripe. The team consists of four people (founder/CEO, sales, marketplace specialist, and customer service), and the company has not raised external capital, operating with a €1,000 share capital since incorporation.

Core offering

EXOSFER develops and sells mechanical and electronic anti-theft solutions for cars, light vehicles, and professional fleets. Its product range includes mechanical devices (steering and pedal locks) and electronic protection systems (OBD port rewire modules and RFID-blocking key pouches) designed to counter modern electronic vehicle theft techniques such as relay attacks and OBD key reprogramming. Products are sold online across Europe and through approved garage partners in France.

Product overview

EXOSFER offers a portfolio of vehicle antitheft solutions comprising four main products. The portfolio includes two mechanical antitheft devices (Bloque Volant and Bloque Pédale) that provide physical barrier protection against vehicle theft, and two electronic antitheft solutions (WAVE Protect and OBD Protect) that protect against modern electronic hacking techniques such as keyless entry signal interception and OBD port reprogramming. The products are designed to work complementarily, with mechanical devices providing visible deterrence and electronic solutions addressing sophisticated pirating methods that account for the majority of modern vehicle thefts.

Priced at €99.00 TTC, with an optional at-home professional installation service available across France.
• Bloque Volant Mechanical anti-theft device that physically locks the steering wheel, providing visible deterrence against vehicle theft. Made of hardened steel for maximum resistance, designed for quick installation. Listed at €29.90 TTC on the website.
• Bloque Pédale Mechanical anti-theft device that locks the brake or clutch pedal, preventing the vehicle from being driven. Discreet design that remains hidden until a thief attempts to steal the vehicle. Listed at €29.90 TTC.

Quantifiable outcome
