Our Story
We protect your business with technical expertise
Viharnis was founded with a clear goal: to offer specialised competence
in cybersecurity and modern systems development. We are a
technically focused company (HW/SW) that puts security first.
With experience spanning IT architecture to advanced penetration testing, we help
businesses secure their infrastructure and build the systems of the future —
from hardware to software.
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.
What we do today
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).
Systems Development (SW)
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
We build relationships the same way we build systems: with transparency and sustainability
We don't add security at the end — we start every project with a threat analysis.
We specialise in complex challenges where off-the-shelf solutions are not sufficient.
We recommend solutions that are technically sound and secure, not just the trendiest ones.
