Who typically uses the Lindy USB Port Blocker?

This tool is widely trusted by government agencies, military branches, and the energy/offshore sectors. It is ideal for any organization requiring high-level physical data security on shared workstations or sensitive systems

How does the Port Blocker kit work?

The kit uses a mechanical "key" & several "locks. You attach a lock to the key, insert it into the USB port, and release the sliding mechanism to leave the lock in plac. It then sits flush with the port & can only be removed using the matching key.

Does this require any software or drivers?

No. This is a purely physical security solution. It requires no software installation or configuration, making it compatible with any operating system and ideal for air-gapped or restricted systems.

Are the keys universal across different colors?

No. For security and zone-management purposes, keys are color-coded. A blue key will only work with blue blockers. This allows administrators to manage different security zones or departments using different colored kits.

Can these blockers protect against "BadUSB" or malware injection?

Yes. By physically blocking the port, these devices prevent the insertion of malicious USB devices (like Rubber Duckies) that can inject malware or steal data before software-level security even recognizes the device.

Il prodotto è ottimo... ma serve davvero?

Sinceramente? Soldi buttati. Perché mai uno dovrebbe "proteggere" gli ingressi USB? Chi lascia il computer incustodito in luoghi pubblici? Per carità, il prodotto è di ottima qualità e fa esattamente ciò che dice, però prima di comprare una cosa simile consiglio di pensarci bene, perché non ci sono tanti motivi per volerlo...
