Meet Your Fractional CISO

When a threat strikes, it's not just about software. It's about judgement.

Ian Thornton-Trump has spent three decades building that judgement, and he can put it to work for your organisation as an Inversion6 fractional CISO.

Ian has been the CISO who answers to the board, justifies the security spend and owns the response when something goes wrong. He has led security operations for enterprise threat intelligence providers and advised organisations in sectors such as insurance, banking and healthcare, where the cost of getting it wrong is measured in regulatory action and lost trust.

Ian's services are perfect for organisations who need more than a junior analyst working from a checklist, but can't justify a six-figure permanent CISO hire in their budget. Not only can he build the security operations, set the strategy and stand up the threat intelligence programme, he can brief your leadership in language the board understands.
