Technology advisory & security leadership
We work at that gap between strategy and execution — providing the senior advisory, fractional leadership, and the delivery capacity that organisations need to close it.
We help you address technology debt accumulated with organic cloud adoption using well-architected cloud environments. We balance cost efficiency, resilience, and delivery at speed using governance frameworks that align engineering, finance, and security.
We add most value where
Board-level technology and security leadership on a retained basis. We step into the gap for organisations that need senior strategic guidance without the overhead of a full-time hire — owning the agenda, not just advising on it.
Define and deliver a security programme aligned to your risk appetite and business objectives — not a checkbox exercise. We bring structured decision-making, built to last with clear adaptable frameworks for prioritising, funding, and evolving the security programme as your business changes.
Technology and security assessment for M&A, investment, and partnership decisions — We provide boards and investors with a clear-eyed view of technical risk, debt, and opportunity before committing.
Helping organisations adopt AI responsibly — assessing risk exposure, defining governance frameworks, and ensuring security is embedded into AI initiatives from the outset rather than retrofitted later.
Bridging operational and information technology environments safely — network segmentation, visibility, and governance for organisations where industrial and enterprise systems increasingly share the same infrastructure.
Bespoke, highly technical security assessments with a specific outcome in mind — testing your controls and security operations teams under real conditions.
Stiliyana Simeonova - Founder & Principal
Epsilon Labs was founded on a simple premise: organisations deserve technology leadership that is both technically credible and commercially grounded. Too often, technology and security advisory operates in isolation from broader business strategy — and business strategy ignores the broader implications of technology decisions.
Our founder is a technology leader with twenty-five years of experience spanning software engineering, systems architecture, strategic advisory, and senior leadership across media, life sciences and diagnostics, financial services and telecom.
Our careers are defined less by a single discipline than by a consistent drive to build, modernise, and deliver — in environments where that is genuinely hard - our people held technology and security director roles with remit extended into enterprise technology transformation, cloud modernisation, M&A integration, and operational excellence.
We reserve a portion of our capacity each year for pro bono and subsidised work with civil society organisations — investigative journalists, human rights groups, and NGOs who face serious threat environments but cannot access the level of expertise they need at commercial rates. This work runs alongside our commercial practice and is funded by it.
Growing organisations that need senior technology or security leadership without a full-time executive hire — on a retained or project basis.
Publishers, broadcasters, and investigative outlets where data protection, source security, and editorial independence are mission-critical.
Human rights organisations, investigative journalists, and advocacy groups operating under elevated threat conditions. We offer pro bono and subsidised engagements for qualifying organisations — get in touch to discuss.
Organisations with OT and ICS environments seeking specialist expertise in industrial cybersecurity, IT/OT convergence, and resilience.
AI and green technology initiatives where security and governance need to be embedded from the start, not retrofitted after the fact.
Firms handling sensitive client data that require board-level security leadership and a clear programme for managing information risk.
We work in small, senior teams embedded in your organisation. No junior consultants doing the work while a senior name appears on the engagement letter. The practitioners you meet at the start are the practitioners who deliver.
Our approach is built around one principle: establish what good looks like in one place first, make it genuinely useful, and let the rest of the organisation adopt it because it reduces their burden — not because it has been mandated from above. We call this the pull model.
We also use AI-assisted tooling to accelerate estate mapping, account inventory, policy enforcement, and compliance monitoring. This reduces delivery time significantly without reducing quality.
Our practitioners come from security and engineering backgrounds — not just advisory. When we design a cloud governance model or a shared infrastructure platform, we are thinking about how it holds up under pressure, not just how it works on day one. In manufacturing and life sciences environments specifically, we bring direct experience of IT/OT convergence — an area most cloud modernisation firms will not go.
Structured assessment of your cloud estate, governance maturity, ownership model, and delivery capability. We do not recommend anything before we understand your actual situation. The output is a clear, honest picture — not a generic best practice report.
Design and implementation of the governance foundations your estate is missing — cloud organisational structure, ownership model, guardrails, visibility tooling, cost controls. We do this at enterprise level first, where we can move fast. The result is a working model, not a design document.
The model becomes available to the rest of the organisation. Operating companies adopt it because it is genuinely useful and reduces their workload. We build internal capability so the organisation becomes self-sufficient. The engagement ends when your team owns it.
Perspectives on technology leadership, security strategy, and the decisions that organisations get wrong. Written for practitioners and leaders, not for search engines.
