BLACK X is the first residential smart lock system to achieve certification under both relevant Sold Secure standards, recognising its advanced mechanical and digital security.

The RockSolid 8590 survived both bolt-cutter and angle-grinder attacks. It wore down the grinder disc within 30 seconds, with minimal damage to the lock.

The RockSolid received a perfect 10/10 and was one of only two locks that could not be defeated. It resisted an angle-grinder attack for 10 minutes.
