vCISO or in-house CISO — when each option makes sense for your business

The question comes up repeatedly in conversations with growing small and mid-sized companies: 'Do we need someone for security in-house?' It is usually followed by a counter-question: how many employees handle sensitive data, do you have a regulatory obligation (NIS2, GDPR, ISO 27001 client requirements), and what is the budget? The answers to those three questions almost always determine the direction.

An in-house CISO makes sense when you have complex, continuously evolving IT infrastructure and security is a strategic function that changes daily — financial institutions, healthcare, telecoms, critical infrastructure. For a company of 50 to 200 employees without weekly real-time security incidents, a full-time CISO costs between 60,000 and 120,000 EUR per year in the region, plus benefits and overhead. Difficult to justify.

The vCISO model — engaging an experienced security leader part-time — gives you the same expertise at significantly lower cost. Typically that means 20–30% of an internal CISO's price for 80% of the benefit: strategic risk management, ISMS setup and maintenance, audit preparation, incident response planning, and communication with management and auditors.

Where a vCISO cannot replace an in-house CISO: when you need 24/7 availability, a deep technical incident response team, or specific regulatory oversight requiring a full employee (for example, certain NIS2 requirements for operators of essential services in the EU). In those cases, start with a vCISO for ISO 27001 implementation and capacity building — an internal CISO comes when the organisation is ready.

Our vCISO service is designed for companies that have outgrown the 'security is an IT problem' phase but are not yet at a level requiring a full-time position. We combine the strategic role with a practical ISO Toolbox — templates, risk registers, SoA, policies — so the company receives complete governance, not just advice.

If you are weighing the options, book a no-obligation call. See what we offer on the vCISO and ISO 27001 service page.
