Six advantages.
Built with dedication and passion.
M4SS designs secure solutions for the entire infrastructure, even when the system plugs into existing machinery. When your foundations rest on cybersecurity, whoever builds always knows their way around, on the new as much as on the existing, because they know the ground their stronghold will rise on.
Secure-by-design
Security isn't a patch you add later. Our system architectures are built with strong authentication, role and data segregation, audit trails, hardening by default, encrypted and authenticated OTA updates. Adding it later costs more and is less effective. What's more, today it's a legal obligation imposed by the CRA (Cyber Resilience Act) on hardware distributors and manufacturers.
Memory-safe Rust
We develop embedded firmware, software and infrastructure in Rust, by choice. The memory-safety guaranteed by the compiler eliminates entire classes of vulnerabilities (buffer overflow, use-after-free, data race) that with C and C++ would require continuous auditing to keep under control.
Open source as strategy
The software we produce, wherever possible, is released under an Open Source license, as are the components we use, in order to avoid any vendor lock-in. For us and for our clients.

Compliance, lived from within
M4SS is an important entity NIS2-registered with ACN (National Cybersecurity Agency) and is a producer of hardware subject to the CRA Regulation (Cyber Resilience Act, EU 2024/2847). The CRA compliance process for our CDM (Communication Data Module) is underway. When we assist a client with compliance, we understand what they're asking for. And we know how to answer.

A single infrastructure
The S451 platform connects all endpoints without fragile joints between different vendors' products: WireGuard®-encrypted communications, industrial Linux® gateway (Yocto), CDM (Communication Data Module) for encrypted radio communications over a proprietary protocol (LoRa® 2.4 GHz). When an integration breaks in production, it's usually one of those joints: with S451 that risk is eliminated at the root.

Research and validation
The S451 technology is the subject of an experimental thesis at the University of Modena and Reggio Emilia ("Study and Development of Secure IIoT Updates with S451 Technology"). Our security proposals to the Rust ecosystem go through the RustSec advisory database, where they are evaluated by third parties before being published. The projects we develop access selective EU programs, with independent technical evaluation. The M4SS methodology doesn't only live in our projects: it is studied and verified outside M4SS too.
