Brussels, Belgium & Toulouse, France — March 17, 2026. CYSEC, a pioneer in cybersecurity and data protection for space and critical infrastructure, and Space Applications Services, the developer of the world-class mission control framework Yamcs, today announced a strategic partnership to simplify the deployment of end-to-end secure satellite links.

The collaboration creates a powerful synergy for satellite operators: by leveraging the native Space Data Link Security (SDLS) implementation already available in Yamcs on the ground and pairing it with CYSEC’s ARCA SATLINK Space library on-board, missions can achieve full CCSDS-compliant security with significantly reduced integration effort.

Proven Interoperability: From Ground to Space

As the space industry adopts the CCSDS SDLS protocol to protect against unauthorized access and data interception, a major hurdle for operators has been the “missing link” on the satellite itself. While modern ground segments are increasingly capable of handling encrypted frames, flight software must be equally equipped to process them.

The partnership bridges this gap through a pre-validated architectural approach that has already been put to the test. CYSEC and Space Applications Services are pleased to announce that the interoperability between ARCA SATLINK Space and Yamcs has been successfully tested, confirming that secure frames generated on the ground are seamlessly processed by the on-board security library.

• On the Ground: Yamcs, by Space Applications Services, integrates a robust ground implementation of the SDLS protocol. It allows operators to manage Security Associations (SAs) and apply authentication and encryption to telecommand and telemetry frames directly within the mission control environment.
• In Space: ARCA SATLINK Space is a modular implementation of the SDLS protocol that can be adapted to any On-Board Computers (OBC) thanks to a highly-configurable toolchain 

Key Benefits for Satellite Operators

By utilizing this verified ecosystem, satellite manufacturers and constellation operators benefit from:

• Verified Compatibility: A “plug-and-play” experience where Yamcs-generated secure frames are natively compatible with the ARCA SATLINK Space library, as proven in recent successful integration tests.
• Rapid Compliance: Instant alignment with ESA and NASA security standards for CCSDS data links, moving missions from “clear text” to “secure” in record time.
• Simplified Key Management: A streamlined workflow for managing cryptographic keys and Security Parameter Indices (SPIs) between the ground station and the flight software.
• Optimized SWaP: ARCA SATLINK Space is optimized for low-resource environments, ensuring that adding security does not compromise the performance of the satellite’s primary mission.

“Space Applications Services has done the heavy lifting by embedding SDLS into the Yamcs ground segment,” said Mathieu Bailly, VP Space at CYSEC. “By providing the corresponding space-side implementation and successfully testing our interoperability, we are giving operators a complete, flight-ready loop that ensures their mission is protected from day one.”

“Our goal with Yamcs has always been to offer a flexible, standards-compliant framework for modern space missions,” said Mathieu Schmitt, Division Manager – Ground Systems & Software at Space Applications Services. “This partnership with CYSEC allows our users to extend the ground-side security they already have in Yamcs all the way to the satellite, providing a truly end-to-end secure solution that we have already validated together.”

At the Network and Distributed System Security Symposium (NDSS) 2026, researchers introduced a groundbreaking advance in space cybersecurity: HoneySat, the first high-interaction satellite honeypot framework that convincingly emulates real satellites to attract and study real adversaries. The work addresses a critical shortfall in our understanding of how threat actors target space systems.

Satellites underpin countless essential services, from global navigation and communications to Earth observation and scientific research. For many years, the cybersecurity of space systems was often seen as a niche concern, partly due to proprietary technologies and the perceived isolation of satellite links. But with the rise of small satellites, accessible ground station technology, and standardized communications protocols, that perception no longer holds. These shifts have broadened the potential attack surface and made it easier for both benign researchers and malicious actors to interact with space assets.

A major challenge in securing satellites has been the lack of real-world empirical data on attacks.

Without authentic datasets, security researchers must rely on theoretical models and simulations that may miss critical details about adversarial behavior. To bridge that gap, the authors of the HoneySat paper, including a multidisciplinary team from institutions such as CISPA Helmholtz Center for Information Security, New Mexico State University, Universidad de Santiago de Chile, Texas A&M University–Corpus Christi, and collaborators from industry and academia, proposed an innovative solution: a high-interaction honeypot tailored specifically for satellites.

What sets HoneySat apart is its depth of simulation.

Unlike low-interaction honeypots that offer limited scripted responses, HoneySat simulates both the network services and the deeper operational behavior of a satellite. It provides realistic command interfaces, believable telemetry, and mission-like interactions, presenting attackers with an environment that closely mimics an actual spacecraft’s systems. This realism helps lure adversaries into revealing their tactics, techniques, and procedures in a controlled research environment.

To evaluate the effectiveness and fidelity of HoneySat, the working team deployed the system on the public Internet. They also surveyed experienced small satellite operators about the realism of the emulation. The results were compelling: 90 % of operators rated HoneySat as realistic, and the online honeypot captured four distinct adversarial interaction sessions, collecting 22 specific flight software commands sent to the satellites. These interactions provide rare and valuable insight into how real-world attackers behave when engaging with what they perceive as satellite targets.

In addition to Internet-based deployment, the authors carried out a hardware-in-the-loop experiment with an operational small satellite in orbit. HoneySat successfully communicated with the real spacecraft, validating the fidelity and extensibility of the framework in a real-world context.

Crucially, HoneySat brings incredible ease and flexibility, empowering players both big and small to adapt the tool to their specific missions and infrastructure. Utilizing a highly modular design featuring customizable “Satellite Personalities” and “Ground Configurations”, organizations can effortlessly mimic their unique assets. Because of this streamlined architecture, changing simulated satellites and communication protocols to fit a specific mission takes as little as a couple of days of development.

The development of HoneySat marks a significant step forward for satellite cybersecurity. By generating authentic adversarial interaction data, the research community can now analyze real attack behavior rather than relying solely on speculative models. This knowledge can feed into more robust threat modeling, enhanced defensive designs, and improved operational practices for satellite systems.

Gabriele Marra, one of the main contributors to the HoneySat framework and now Security Engineer at CYSEC, a company known for its focus on space cybersecurity solutions, commented that frameworks like HoneySat represent a much-needed evolution in how the industry approaches threat intelligence. According to Gabriele Marra, “Realistic attack data is key to building resilient space systems; tools like HoneySat enable defenders to understand not just that attacks happen, but how and why they unfold the way they do.”

Indeed, as satellite deployments grow in number and importance, so does the necessity of understanding how adversaries engage with these systems. HoneySat’s open-source framework and demonstrated efficacy establish a new benchmark for research into space threats, empowering defenders with data that was previously inaccessible.

As space continues to become an increasingly contested domain, empirical frameworks like HoneySat will be instrumental in evolving both the theory and practice of satellite defense. By capturing real adversarial behavior in realistic interactions, this work not only advances academic research but also offers tangible tools and insights for operators, policymakers, and engineers striving to protect the critical infrastructure orbiting above us.

Toulouse, December 7th, 2025 : The French Space Agency (CNES) awarded a contract to CYSEC in the framework of the France 2030 programme to develop and test in orbit an augmented version of its product ARCA SATLINK capable to achieve high-speed payload data downlink for Earth Observation missions

After rolling out “ARCA SATLINK”, the first commercial, software-based  implementation of the Space Data Link Security (SDLS) protocol by the CCSDS, CYSEC is now announcing a contract with CNES to develop and test in orbit a hybrid version of the product leveraging hardware crypto acceleration on board.

Indeed, a software implementation of the SDLS protocol on board is capable of achieving a dozen Mbps, which is sufficient for Telemetry and Telecommand data uplink and downlink.

However, as the demand for Earth Observation data is growing, more and more satellite operators are flying instruments capable of collecting massive amounts of data that need to be transmitted back to Earth for processing. This is a critical step as radio-frequency links have a large footprint, meaning attackers can easily eavesdrop data that are not protected.

The new development of ARCA SATLINK will enable operators to securely downlink EO data at high speed without compromising on security by adding encryption and authentication mechanisms. 

The new ARCA SATLINK product will be flying on a rideshare mission hosted on a U-Space platform with innovative payloads from ACTIA Aerospace, Airbus Defense and Space, STEEL Electronique and ION-X.

“We’re very thankful to the CNES to give us the opportunity to demonstrate in-orbit a solution that is under high demand in the market currently. The IOD/IOV mission will help us measure the actual performances we can achieve using FPGA acceleration and convince our clients about the reliability of the solution” said Anna Barraqué, Head of CYSEC France and ARCA SATLINK Team Leader

Julien Airaud, Space Cybersecurity Senior Expert at CNES added : “The CNES has been involved since the inception of the Space Data Link Security protocol, we’re delighted to see companies like CYSEC turning it into a commercial product and supporting them in developing and testing new capabilities in orbit”

Forward-Looking Statements

This release contains forward-looking statements that involve risks and uncertainties. Actual results may differ materially due to factors beyond CYSEC’s and Armada’s control.

Today’s business dynamics put IT organizations under significant pressure to deliver agility, scalability, and resilience.

The adoption of public cloud platforms has become a proven strategy for companies seeking to expand their infrastructure and quickly adapt to fluctuating demand. However, for many organizations, concerns remain about the exposure of sensitive corporate data and the strict regulatory landscape that governs data protection and operational resilience.

Regulations such as the EU’s DORA Act, AI Act, and GDPR make it challenging for enterprises to move critical workloads to external environments without compromising compliance and security.

CYSEC addresses this challenge by offering a secure foundation for extending traditional on-premises infrastructure into the public cloud. By combining confidential computing, system hardening, and remote attestation, CYSEC creates trusted execution environments, also known as enclaves, that isolate sensitive applications and data (encryption in all states) wherever they are deployed. This includes public or private clouds, edge environments, or partner infrastructures.

In public cloud scenarios such as Microsoft Azure, CYSEC’s solution allows enterprises to leverage the scalability and elasticity of public cloud resources while maintaining complete privacy and control over their data. Sensitive assets are protected from any external or internal exposure, ensuring that corporate data remains secure even in shared environments. Companies can confidently deploy critical workloads to the cloud without surrendering control of encryption keys or trust mechanisms to public cloud service providers.

This approach is particularly valuable for sectors such as banking and financial services (BFSI), life insurance, retail, manufacturing, governmental organizations, and supply chain or logistics.

These industries handle highly regulated or confidential data and often require strong guarantees of data integrity and confidentiality when interacting with their partner and customer ecosystems.

With CYSEC, they can create a secure, trusted layer on top of public cloud infrastructure that mirrors the protection standards of their on-prem environments.

The key benefits for companies adopting this hybrid security model include the ability to scale flexibly with public cloud capacity while retaining on-prem-like control and visibility.

Organizations can bring their own encryption keys and manage them internally, maintaining full ownership of their data security. The solution ensures no dependency on cloud service providers within the chain of trust. This architecture enables business continuity, reduces operational risk, and minimizes the effort required to manage hybrid environments.

By replicating on-premises security models in the public cloud, companies gain the freedom to innovate faster, reach customers more efficiently, and collaborate with partners securely. The result is a hybrid IT ecosystem that delivers both agility and compliance—two qualities often seen as contradictory in traditional cloud adoption strategies.

With CYSEC, enterprises can finally expand their digital footprint beyond their physical data centers into the cloud securely and confidently, ensuring that their growth never comes at the expense of data privacy or operational control.

Main benefits:

• Scale with public cloud
• Bring your own keys:
• Replicate on-prem security in an hybrid architecture
• On-prem management of all encryption keys used in the hybrid cloud environments 
• No dependencies from CSPs in the chain of trust
