From their specs, I'd say they offer about the same security as a Liberty/Champion/Browning. The 1/8" steel is the same as 10 gauge. They offer one line that has 3/16" steel in the body. That might put it close to some of the Fort Knox's, but it still won't get it up in the Graffunder ranks (and likely not even in the Amsec's).
The Graffunder has some major steel. The "good" Amsecs, have some pretty thick steel, and they also use a concrete-like "fill" for their fireproofing, which adds an extra bit of security (most safes just have 1-3 sheets of drywall for fire-proofing).
