Tamper-evident & physical security
Chain of custody isn't just for forensics labs: serialized seals on a server chassis, a cable lock on the laptop, keyed blockers in the open USB ports. Cheap, visible, auditable controls — and they cross-check with the Faraday line and safes for the full physical layer.
Kensington laptop locks
The physical control auditors actually look for at desks: a cable lock turns grab-and-go laptop theft into noisy, slow work. Check your laptop's slot type first (standard T-Bar vs. the newer Nano/wedge slots).
Combination Cable Lock (K64670AM)
Keyless 4-wheel combo, T-Bar, 6 ft carbon steel — the default pick.
T-Bar Keyed Lock (K65035AM)
Keyed and anti-pick with a 10 mm head for thin laptops. Not for newer Dell wedge slots.
Combination Ultra (K64675US)
60% thicker cut-resistant cable — the heavier-duty option.
Tamper-evident seals — chain of custody
Serialized, one-time-use seals are how evidence handling actually works: number logged, seal applied, any tampering is permanent and obvious. The same discipline works on server chassis, network closets, firmware-flashed laptops, and go-bags.
Wire padlock security seals — 500-pack, serialized
One-time-use, serial-numbered, non-removable without visible evidence. Assets, meters, cases, evidence.
Serialized bag and VOID-label picks get pinned ASINs after live verification — search links until then.
USB port blockers
Keyed physical plugs for unused USB-A/USB-C ports — the anti-juice-jacking, anti-exfil control that costs less than lunch. Pairs with the USB data blocker in the Nitrokey accessories and the Faraday travel kit.
