Quiet precision
for complex,
critical work.
Like our namesake, we watch what others miss. Hedwig Tech helps organisations design, secure, and scale the systems their business depends on — where failure is not an option.
Security Consulting
Threat modelling, assessments, vulnerability analysis and hardened security frameworks for critical systems and infrastructure.
Large-Scale Systems
Architecture and optimisation for high-performance, resilient systems handling mission-critical, distributed workloads.
Software Architecture
Strategic design and technical advisory for enterprise-grade applications, microservices and complex system integration.
Space & Embedded
Flight-grade software, verification and safety engineering for embedded and space systems with zero tolerance for failure.
Principles that hold under pressure.
Evidence over opinion
Decisions are grounded in threat models, measurements and proofs — not vendor slides.
Failure-first design
We assume components break and design the system to stay correct when they do.
Small senior teams
You work directly with the engineers doing the work — no layers, no handoffs.
Leave you stronger
We transfer knowledge so your team owns and can evolve what we build together.
A Swiss consultancy for the systems that carry weight.
Based in Ticino, Hedwig Tech Sagl is a specialised consultancy focused on critical software systems and security. We help organisations navigate complex technical challenges in mission-critical environments.
Our engineers have shipped software for space, finance and public infrastructure — domains where correctness is measured in consequences, not tickets.
