From ISO 27001 to AI governance, Bitsecura brings Big 4-calibre GRC expertise directly to your organisation — without the overhead.
We work alongside in-house teams, not above them. Our engagements are shaped by your actual posture, sector, and priorities — not pre-packaged templates. When we finish, you're left with frameworks that hold up under scrutiny and people who understand them.
Bitsecura is a specialist GRC consultancy with a strong focus on ISO certifications — ISO 27001, ISO 27701, and ISO 42001 being our best-known work. We bring over 20 years of consulting experience to every engagement, drawing on a background that spans Big 4 firms and complex regulatory environments across multiple sectors.
Whether you're pursuing ISO 27001 certification, navigating DORA or NIS2, or building a long-term GRC function, we aim to give you clarity, capability, and confidence — not just a report.
Bitsecura is led by Arian Sheremeti, Principal GRC Consultant and Auditor. After years at PwC and Deloitte, Arian now runs Bitsecura independently, which means you work directly with the person who owns the outcome, from the first scoping call to the closing meeting.
With more than 20 years across start-ups, financial institutions and critical-sector operators, his work centres on one idea: turning complex frameworks into practical decisions and audit-ready evidence, without compliance theatre. That covers ISO 27001, ISO 27701 and ISO 42001 management systems, SOC 2, EU DORA and NIS2 readiness, and the NIST Cybersecurity Framework.
Arian is a regular commentator on cybersecurity for national television and industry panels, and shares practical GRC insight with over 5,000 followers on LinkedIn.
Four principles that govern every engagement, every recommendation, and every conversation we have.
We uphold the highest standards of integrity in all our actions, ensuring that our clients can trust us to protect their critical assets and give them straight answers — even when that's not what they want to hear.
We strive for excellence in everything we do — from the frameworks we design to the advice we deliver. Good enough is not a phrase that appears in our work. Every deliverable is held to the standard we'd apply to our own organisations.
We take our responsibility seriously. Our solutions are not built to tick boxes — they are designed to genuinely protect operations and reduce risk. We own the quality of every recommendation we make.
We are dedicated to our clients' security and success, providing tailored solutions that protect digital assets and support business goals — for the long term, not just the duration of a project.
