Additional Features
Provides continued insight during power outages or in environments with unstable electric power.
Power Loss Protection
On-board protection resists and recovers from Denial of Service (DOS) attacks
DDoS Protection
Built-in anti-tamper protects against physical interference.
Tamper Resistance
Physically enforced one-way data flow prevents any malicious code from reaching the protected equipment or network. Fend’s diodes use full optical isolation that allows data out and nothing in.
Full Optical Isolation
Easily set up and configure your diode with Fend's Diode Configuration Tool
Field Configurable
Fend isolates the protected system and offers encrypted protocol options for data in transit.
Onboard Encryption
Rugged design allows Fend diodes to live alongside the equipment they protect. Flush mount and DIN rail options. ETL tested / FCC Certified.
Designed for Industry
Full electrical isolation between input and output sides of the diode prevents side-channel attacks over power lines.
