Protecting servers has become a priority. Not just the data protection, but physical barriers to unauthorized personnel. Most banks have no physical protection at all.
Given today's world of identity and privacy theft, and the incumbent liability that banks and other financial records holders are exposed to, it makes sense to secure server rooms from physical theft as well as electronic.
Banks, mortgage companies, and other providers are increasingly required to keep a larger variety of confidential records and keep them longer. This has caused a paper debacle and adds to security issues. Cages can be constructed to keep unauthorized personnel away from these records. Controlling access is key. Besides outright theft, damages can occur if the wrong people are allowed access to vital stored paper records.
Primary/secondary lenders records generate substantial paper such as deeds, notes, applications, loan documents, etc., that must be kept for the life of the loan. It makes sense to segment and protect these records. If security caging isn't adequate due to volume, consider wire security panels that can be attached to bulk storage racks.
HR records are also proprietary, and appropriate for security cages. The implications for privacy violations through human resources records are potentially damaging and can be defended against with adequate physical security.
Items like toner, printers, software, and computer hardware continue to be subject to theft from within. Wire security cages have the advantage of allowing inventory counts without opening the cage to the wrong people.
