Protects USB Type A ports from unauthorized access
Simple, Effective USB-A Port Protection
The Lindy USB Type A Port Blocker is a compact, effective physical security tool designed to help prevent unauthorised access to USB ports on shared, public, or sensitive systems.
By inserting a locking cap into any USB-A port, system administrators can:
Used widely across education, retail, government, and enterprise sectors, these blockers offer a low-cost way to introduce physical security – no software, training, or configuration needed.
Each blocker is colour-coded to match its dedicated removal key, simplifying zone-based access management. Available in Blue, Pink, Green, Orange, and White for easy visual control.
Additional blocker packs and spare keys are also available for expanded or multi-user deployments.
Note: Keys are colour-specific and only compatible with blockers of the same colour.
Physical USB Access Control
Blocks insertion of USB drives, mobile devices, or peripherals.
Visual Deterrent
Communicates clearly that access is restricted.
Quick & Easy to Use
No tools or software required – simply click in to install or remove.
Colour-Coded Key System
Keys only work with matching-colour locks for controlled access.
Low Maintenance, High Scalability
No moving parts or software – deploy easily across entire organisations.
Complementary to Digital Security
Enhances endpoint protection alongside USB lockdown software or group policies.
Education
Lock down access to USB ports on classroom PCs and shared lab devices.
Retail & Public Terminals
Prevent customers or users from inserting personal USB devices into kiosks or point-of-sale terminals.
Corporate IT
Enforce endpoint security policies and protect against rogue device access.
Government & Defence
Add a physical security layer to systems handling sensitive or classified information.
Offices & Shared Workspaces
Avoid accidental damage or misuse of equipment.
Healthcare & Labs

Protect Critical SFP Ports from Tampering, Damage or Unauthorised Access
The Lindy SFP Port Blocker provides a fast, effective way to physically secure unused SFP (Small Form-factor Pluggable) network ports. These compact blockers are ideal for safeguarding fibre infrastructure in sensitive IT environments, AV-over-IP setups, and networked installations where access control is essential.
By preventing unauthorised connections, accidental cable insertions or foreign object intrusion, Lindy SFP Port Blockers reduce the risk of port damage and potential downtime. A robust insertion mechanism keeps each blocker firmly in place, with colour-coded keys ensuring only authorised removal. Additional keys and blocker packs are also available.
