Built for the GCC.
Backed by Global Expertise.
Founded by Andrei Buiu, SIAN Cyber Security was created to solve a specific problem: GCC enterprises need security partners who understand both local compliance frameworks and world-class technical security.
Most security firms in the region are either global consultancies loosely adapting Western frameworks, or local providers without hands-on experience at the highest levels of security engineering. SIAN bridges that gap.
With direct experience from the European Parliament, Snyk, and Binance -- and a US patent in IoT security -- SIAN combines institutional-grade expertise with deep specialization in AI security, DevSecOps, and GCC compliance. Everything we do is backed by SIAN Validate, our compliance automation platform built to make advisory work last beyond the engagement.
What Drives Us
Four principles that shape every engagement, every recommendation, and every line of code we ship.
Systems Over Reports
We build lasting security infrastructure. SIAN Validate is the embodiment of this principle -- a live compliance system, not a PDF that collects dust.
GCC-First Focus
Deep expertise in NCA ECC, NESA IAS, PDPL, and ADHICS. Every engagement is architected around the regulatory realities of the Gulf.
Data Sovereignty by Design
All client data is processed and stored exclusively on AWS UAE (me-central-1). Zero offshore processing, zero exceptions.
Transparency Over Marketing
ISO 27001 certification is in progress. We believe trust is earned through recognized standards, not marketing claims.
