That is not what a SCIF is used for. A SCIF is for discussing or electronically processing information classified at TS/SCI level (sensitive intelligence-related information). Counterexample: For Unclassified and Unclassified//FOUO websites made available on the public internet by DoD/IC, you can even access them from home using a valid CAC/PKI card (smart card holding a client certificate affirming your identity). This is not just informational websites, it includes your unclassified webmail, Intelink-U (web gateway to some sites), and more. They are far more lax than many private corporations are. Physical security is surely good to have, but your reference to military is not a great one as military and the intelligence community hedge a lot on digital security, not physical security unless the information is highly sensitive (Even then, it is in combination with very strong digital security measures regarding setup of the network, VPN, and all endpoints).
