We're very aware of how important cyber-security is, in fact we just finished a massive sign on migration to a new authentication platform to bolster these very efforts for security.

Once we have completed all necessary maintenance for this migration we will swiftly implement HTTPS across the entire Tom's Hardware site and Forums.
