SYLink Technologie — French cybersecurity vendor and designer

• Hardware

  Electronic design (PCB), assembly and test (PCBA), server hardware design, machine optimization. The full industrialization chain in France, from PCB to final enclosure.

• AI & LLM

  Designing LLMs adapted to the use case (cybersecurity, plus vertical client domains) on our NVIDIA DGX Spark (GB10) cluster. SYLink AI family (MoEⓘ), bilingual FR / EN, on-premiseⓘ or sovereign cloud.

• Software

  Multi-language development: OS and kernel, C / C++, Rust, Go, C#, Python, TypeScript / React. CISO console, sovereign API, correlation engine, agents and probes — 100% French stack.

• Sovereign cloud

  Green IT datacenter in France, multi-tenant supervision for MSPs, HDSⓘ compliance for healthcare. No data leaves the European Union.

• Forensics & data recovery

  Memory, disk and network analysis, multi-stage attack reconstruction, post-incident data recovery, support for justice and CERTs.

• Threat Intelligence

  Darkwebⓘ watch, criminal marketplaces, brand watch and IOC correlation across open and closed Internet. From 12 to 58 modules depending on Leaksⓘ tier.

From PCB design to in-production machine optimization, we master the entire hardware chain: electronic design, PCBA, server design, kernel tuning, MCO / MCS. Every step is operated in France.

• PCB design

  Electronic design

  Schematics, routing, thermal and EMC simulation. French components when possible, traceable BOM (Bill of Materials).

  • Schematics
  • Multilayer routing
  • Thermal simulation
  • EMC compliance

• PCBA

  Assembly & test

  Assembly in France (SMT / through-hole), bench functional tests, board validation before enclosure integration.

  • FR assembly
  • AOI / ICT tests
  • Burn-in
  • Per-unit traceability

• Server hardware

  Design & integration

  Chassis selection, CPU / RAM / NIC sizing for each product (Box, Mini, Pro, DPIⓘ), hardened BIOS / firmware integration.

  • 1U / 2U chassis
  • 10 G SFP+ / RJ45
  • Hardened BIOS
  • Supervised BMC

• Machine optimization

  Tuning & MCO / MCS

  Workload profiling, kernel and driver tuning, low-level observability (eBPF), MCOⓘ and MCSⓘ operated from our sites.

  • Kernel tuning
  • eBPF / NUMA
  • 24/7 MCO
  • NATO / Armed Forces MCS

We design domain-adapted LLMs for our customers — cybersecurity first (SYLink AI), and verticals across healthcare, defense, industry. The SYLink AI family includes three models trained in France on curated data (MITRE ATT&CK, CVE, NATO / Armed Forces, NIS2, GDPR). Bilingual FR / EN, deployable on-premise or in sovereign cloud.

Our strength is being able to develop in every language required — from system languages (C, Rust, eBPF) to kernel, up to management applications (C#, Python). CISO console, API, correlation engine, agents and probes: a 100% French stack designed for readability, traceability and compliance.

• C / C++
  OS · kernel · drivers
• Rust
  Critical backends · agents
• Go
  Microservices · CLI
• C#
  Windows tools · endpoints
• Python
  Data · AI · scripts
• TypeScript
  Console · API · front

• End-to-end multi-language

  OS and kernel (C, Rust, eBPF), high-performance backends (Rust, Go, C++), application domains (C#, Python), front (TypeScript / React / Next.js). The right tool for each layer.

• Sovereignty by design

  The full stack — front, API, engine, agents, hardware — is designed, hosted and operated in France. No dependency outside the EU.

• Continuous updates

  New signatures, fixes and features deployed automatically with no service interruption.

• Total auditability

  Every action is traced and explainable, from raw log to AI decision. PASSIⓘ format for sovereign actors.

• One single console

  From the executive to the CISO and the SOCⓘ analyst, everything goes through the same interface — adapted to each role.
