GCHQ grew out of the WW2 code-breaking group based at Bletchly Park and is the British equivalent of the NSA. Recently it was announced that GCHQ will start offering its expertise to private businesses:
Some of the secret technologies created at the government’s giant eavesdropping centre GCHQ are to be offered to private industry as part of new cyber security strategy being unveiled by ministers on Friday.
The idea is likely to be one of the most contentious in the plans, which could lead to the government being paid substantial sums for software developed by the intelligence agency based in Cheltenham.
Opening up GCHQ to commercial opportunities will not deflect it from defending national security, which remains its priority, ministers argue, and the agency has insisted it will not be side-tracked.
However, the new cyber strategy makes clear that the dangers posed by espionage and crime on the web cannot be faced without better co-operation between the two sectors, and that they will have to work together more closely in future.
