Security focus

A technical focus in an uncertain world

Viharnis is not your average consulting firm. We are technicians, developers, and security experts who build solutions that last.

We've recognised that real security cannot be bought as a ready-made product — it must be built into the architecture, whether it's a software application or a hardware device.

2018 - Foundation in IT Security

Started as IT consultants focusing on network security, systems administration, and secure system environments for Swedish businesses.

2020-2024 - Expansion into HW/SW Development

We developed specialised software solutions and integrated them with secure hardware, with a strong focus on IoT and embedded systems.

2025 - Viharnis Refined

Today we are a pure-play partner for your digital security and technical development. We combine deep technical expertise with understanding of tomorrow's threat landscape.

We are your partner throughout the entire technical lifecycle. We secure what you already have and build what you need to grow safely.

Our solutions are used today in everything from property automation to critical infrastructure, where the demands on both performance and security are uncompromising.

Cybersecurity & Pentest

We audit, test, and harden your systems. From penetration testing to continuous monitoring (MSSP).

We build secure, scalable, and modern applications with a focus on Security by Design.

Hardware Solutions (HW)

Design and securing of hardware, IoT devices, and embedded systems for industrial, commercial, and defence environments.

Our Guiding Principles

Security in Everything

We don't add security at the end — we start every project with a threat analysis.

Technical Edge

We specialise in complex challenges where off-the-shelf solutions are not sufficient.
