I have a storage space full of information assets. The room itself is sound; there are no windows, the walls go all the ceiling, and there is only a single entrance with two good stout doors and high precision locks. At the risk of sounding purposefully cagey, assume a 7+-pin master key system with anti-pick features.
My biggest concern is the mullion, the bolted in steel vertical as illustrated in this picture, separating the doors. I feel that it is better than he doors latching to each other, however it also seems like a weakness. Does the mullion present an undue risk? If so, is there a commonly accepted mitigation path?
