FIPS compliance

We are looking to replace our 110c and also address some audit items. We need to install a FIPS compliant firewall with FIPS 140-2 compliant SSL VPN. We are looking at the 200D for the hardware, but I'm confused about the firmware. The only certified firmware that I see on the NIST site is 5.0.10. I know newer versions of the firmware have a FIPS CC compliant mode, but if they aren't certified by NIST I'm afraid we will not pass the next audit. Can anyone please help me understand this better? Thanks.
