About
VixSiren Industrial Cybersecurity Ltd
VixSiren Industrial Cybersecurity Ltd is a cybersecurity company based in Nairobi, Kenya, dedicated to protecting operational technology. We currently work with power plant systems — the control systems that generate, transmit and distribute electricity.
Our approach
The principles we are built on.
Influence, not only access
Conventional security works to keep intruders out. We assume a capable adversary may already be inside, and focus on ensuring they cannot influence the physical process.
Physics as the reference
Data can be forged and credentials can be stolen; the laws of physics cannot. Every reading and every command is judged against what is physically possible and normal for that plant.
Inline by design
VixSiren sits in the command path. A command that the plant’s physical state does not justify is held before it reaches equipment. VixSiren never issues commands of its own, and the plant’s own protection systems always act independently.
Explainable decisions
Every decision carries a plain-language reason, recorded in a tamper-evident log, so that operators, auditors and regulators can see what happened and why.
Mission
To protect the infrastructure that sustains human life.
Vision
A future in which every power plant operates securely and without interruption, forming the foundation of resilient critical infrastructure worldwide.
