After checking this:
http://www.cisco.com/web/strategy/government/security_certification/net_business_benefit_seccert_fips140.html
You'll see that any of the sensors is listed, thus meaning their signatures are not FIPS 140 compliant.
It's going to be compliant if it runs 7.2(1)E4, not really sure.
Probably available at the end of April. We'll have to wait.
Not very sure about GFIRST compliance, couldn't find any information about it.
