Why Colossus?

Colossus was the world's first programmable electronic digital computer. Developed by Tommy Flowers and British codebreakers to allow them to read German coded messages during World War II between 1943 and 1945.

This spirit has led to the NCSC being at the forefront of cyber security helping to make the UK the safest place to live and do business online.

Our History

We are a new organisation, but our creation has not come from a sudden overnight rush of cyber awakening. Over the last century, many milestones – including numerous ones heavily influenced by our parent organisation GCHQ – have brought us to this point, and we must prepare for many more changes.
