One of the guys here was doing data entry for a defence contractor and he needed one of the lower level clearances (since they were developing guidance systems for the MOD).
Strange, I work for an accounting firm and the team I'm in saw info about a project a client was working on for the military and I've never had any security checks. We were just told not to tell anyone about what we saw but I get that all the time, especially when working on football clubs.
Maybe it depends on the type data entry.
Btw, yes accounting firms do more than punch numbers. The reason we saw that particular document was to see if the company could get capital allowances on the R&D they were doing.



nice one.
