CYSEC

What CYSEC does

CYSEC is a Swiss-founded cybersecurity company (legal entity CYSEC SA, founded 2018, headquartered in Esch-sur-Alzette, Luxembourg with offices in Lausanne, Switzerland and Toulouse, France) that delivers the ARCA platform for confidential computing and space-grade cryptography. Its three core products are ARCA Trusted OS — a hardened Linux operating system that runs confidential virtual machines inside AMD SEV-SNP and Intel TDX trusted execution environments with self-hosted ARCA Verification Manager for sovereign remote attestation; ARCA SATLINK — the first and only commercial implementation of the CCSDS Space Data Link Security (SDLS) protocol, providing frame-level encryption and authentication for satellite TM/TC and payload data on both ground and space segments; and ARCA SATCOM — a QUIC-based satellite connectivity optimization solution delivering 7–8x throughput improvement over IPsec baselines across LEO, MEO, GEO, D2D, and 5G links. The company holds 11 filed inventions (5 granted) across major jurisdictions plus 6 exclusive research licences, and ARCA SATLINK has been validated in orbit on ESA's OPS-SAT spacecraft (October 2023) with a 100% success rate on over 2 million TC and TM frames.

The technology stack anchors trust in hardware (CPUs, HSMs, TPMs) with no SaaS dependencies, full-stack attested launch (BIOS/UEFI through VM), sovereign key custody via HSM/Vault, and post-quantum cryptography readiness, while integrating with Microsoft Azure confidential compute, Broadcom vSphere v9, Proxmox, NVIDIA Hopper/Blackwell GPUs, Thales Luna 7 HSM, YAMCS mission control, XtratuM hypervisor, and Kubernetes. CYSEC monetizes primarily through annual subscription licensing for ARCA Trusted OS and ARCA SATLINK software, hardware appliance sales plus managed cloud gateway subscriptions for ARCA SATCOM, and project-based contracts with government space and defense agencies. Distribution combines direct enterprise sales, a three-tier channel partner program (Prime SIs, Regional VARs, Technology/SDK partners), hyperscaler marketplaces, and the CYSAT conference — claimed as the world's largest space cybersecurity event with 2,000+ attendees annually.

CYSEC serves space agencies (ESA, CNES), defense primes (Thales, Leonardo, Secunet), hyperscaler and infrastructure partners (Microsoft Azure, Broadcom, NVIDIA), commercial satellite operators (Viasat, Telespazio, Space42, Saudi Net Link), and NewSpace startups (Leanspace, Reorbit, U-Space, Univity, Ripple), with end customers in defense, critical infrastructure, maritime, aviation, energy, healthcare, and confidential enterprise cloud workloads. The company is backed by approximately CHF 4M+EUR 2M of disclosed venture funding from Line Break Capital, Indaco Venture Partners SGR, Karista Newspace Fund, and Foundation for Innovation and Technology, plus institutional support from DGA, France 2030, and EU programs (IRIS², Galileo, EUDIS), and operates with 1–10 employees.

Core offering

CYSEC delivers the ARCA product family, a unified cybersecurity software platform for critical infrastructure spanning cloud, on-premises, and space environments. ARCA Trusted OS provides hardware-rooted confidential computing inside AMD SEV-SNP and Intel TDX TEEs with self-hosted sovereign attestation. ARCA SATLINK implements the CCSDS SDLS protocol for frame-level encryption and authentication of satellite TM/TC and payload data, with FPGA acceleration up to 10 Gbps. ARCA SATCOM delivers high-throughput, line-rate encrypted satellite connectivity optimization across LEO, MEO, GEO, D2D, and 5G orbits.

Product overview

CYSEC delivers the ARCA product line—a unified cybersecurity platform for critical infrastructure spanning cloud, on-premises, and space environments. The portfolio consists of three core products: ARCA Trusted OS provides confidential computing through hardware-based trusted execution environments (AMD SEV-SNP, Intel TDX) with sovereign attestation; ARCA SATLINK secures satellite communications via CCSDS SDLS protocol with frame-level encryption for ground and space segments; and ARCA SATCOM delivers high-performance, encrypted satellite connectivity with intelligent QoS across multiple orbits. Together, these products establish a comprehensive security posture protecting data at rest, in transit, and in use—from mission control centers to orbital assets.

Direct peers

• GMV: European space technology provider with significant space cybersecurity and satellite ground systems business. Directly competes in the same European space agency and prime contractor accounts that CYSEC serves with ARCA SATLINK and SATCOM.
• Fortanix: Enterprise confidential computing platform built on Intel SGX and AMD SEV-SNP with similar TEE-based VM and key management capabilities. Directly comparable to ARCA Trusted OS for regulated workloads requiring hardware-rooted attestation.
• Wind River Systems: Provider of VxWorks space-grade real-time operating systems and embedded software used widely on-board satellites. Comparable for the ARCA SATLINK on-board and ARCA Trusted OS space-segment positioning where flight-grade OS and security software converge.
