CISO as a Service
A new approach to cyber governance
In today’s digital environment, organisations are facing growing pressure to protect their information systems, sensitive data and business continuity. Cyber threats are becoming more sophisticated and regulatory expectations (e.g. GDPR, NIS 2, DORA) are increasing, while cloud adoption, digital transformation and the rapid integration of AI technologies continue to reshape risk landscapes.
Without clear governance, effective IT risk management and experienced security leadership in place, businesses expose themselves to operational, financial and reputational risks.
The Chief Information Security Officer (CISO) is no longer an optional role. It has become a key strategic leadership function that helps organisations structure their cyber strategy, ensure resilience, and explore and adopt emerging technologies with confidence. Yet, for small businesses that already outsource their IT services, an external CISO (CISO as a Service) is an attractive option. It brings board‑level security leadership to the table without the cost or complexity of a full‑time executive. An external CISO turns cybersecurity from a technical afterthought into a business enabler—aligning risk, compliance, and strategy while keeping IT providers accountable. The result is clearer ownership, stronger defences, and peace of mind, knowing that your security is being driven by expertise.
Why outsource your CISO function?
Access experienced cybersecurity leadership with a proven track record—without lengthy recruitment processes or the challenges of hiring in a highly competitive talent market.
Benefit from immediate guidance, expert coordination and strategic support in the event of a cyber incident, operational disruption or suspected breach, as well as continuity in case of absence, overload or critical incidents. Your security governance is never dependent on one single individual.
Manage obligations linked to DORA, NIS 2, GDPR and ISO 27001, as well as broader governance expectations through a structured and documented framework.
Integrate cybersecurity into your wider IT risk management framework, ensuring that risks are identified, measured, mitigated and reported in line with regulatory or good governance principles.
Your cybersecurity roadmap is tailored to your main business objectives, maturity level, technology environment and actual risk exposure.
How we support you
- Protect
Protect your critical assets, sensitive data, and core business operations by establishing a structured and proportionate cybersecurity framework. This includes defining and implementing effective security controls, overseeing your IT and third‑party providers, and ensuring that protections are aligned with your actual risk exposure. We also strengthen your preparedness and response capabilities, so that security incidents are detected early, managed efficiently and contained quickly to minimise operational, financial and reputational impact. - Govern
Govern cybersecurity with clear accountability by clarifying roles, responsibilities and decision‑making at the executive level. This ensures that cybersecurity is owned, measured and reported in a way that supports informed, risk‑based business decisions. Through regular executive reporting, risk assessments and policy oversight, we align security priorities with business objectives and regulatory expectations, enabling leadership to steer cybersecurity with confidence and respond to crises effectively. - Anticipate
Stay ahead of evolving threats, technologies and regulatory obligations through continuous cyber monitoring and proactive risk management. By monitoring emerging risks, assessing the impact of new technologies or business initiatives, and providing forward‑looking strategic guidance, we enable you to anticipate issues to prevent them from becoming incidents. This approach supports smarter investments, stronger resilience and long‑term cybersecurity maturity, rather than short‑term fixes.
