Simon Veale

Senior architect

Simon fell into IT almost by accident in 1979. When he applied for his first role as a Computer Operator, he had no idea what a computer was! He’s gone on to hold a number of high-level technical positions with the likes of IBM and BT, and has been working with identity management technologies since 1986 (before the internet).

At OCG, Simon is highly valued for his ability to clearly communicate with stakeholders at all levels. He gains an intimate understanding of customer requirements which enables him to develop solutions that truly make a difference.

Before joining OCG, Simon was the pre-sales technical lead for identity management solutions at Microsoft UK.

This led to the delivery of a MIIS 2003 training course (2731) at Microsoft Johannesburg in September 2003 – the first of many training and consulting engagements with OCG, before joining full time in March 2016.
