The FI11PH-M DisplayPort/HDMI KVM isolator prevents vulnerable peripherals from attacking secure computers by ensuring that video and audio flow in a single direction. By preventing host-toperipheral direct access, the secure isolator eliminates data leakage and filters irrelevant data from reaching sensitive computers. The FI11PH-M is designed to provide the highest possible computer & peripheral isolation as demanded by government agencies, military, financial institutions and similar security sensitive customers.
The secure isolator provides the highest possible computer & peripheral isolation as demanded by government agencies, military, financial institutions and similar security sensitive customers.
The FI11PH-M isolator perfectly suits scenarios where vulnerable peripherals or computers may pose a security threat. For example, in a secure meeting room, when an unsupervised (non-secure) guest laptop connects to a projector shared with a classified computer. By isolating the classified computer from the projector, the secure isolator protects the classified computer from being infected by the guest computer by exploiting a projector vulnerability.

How does the High Sec Labs FI11PH-M Protect the EDID Channel
- EDID is read from the display only when the user presses the EDID capture button, typically during installation. This prevents continuous EDID transformation between the display and the source.
- EDID information is parsed to assure that only legitimate information is passed between the display and the source. The Isolator is used as a buffer to protect against transferring malicious code through the EDID channel.
- EDID information is limited to the basic essentials. Instead of passing the full EDID and MCCS, HSL's Isolators limit the EDID to the minimum required.
- The embedded digital audio via DisplayPort/HDMI is also protected due to unidirectional video transfer.
High Sec Labs FI11PH-M Features
- The ultimate solution for securing and presenting sources of different classification level on the same display.
- Supports isolation of large KVM matrix switches and conference room equipment.
- Display Plug & Play (EDID) Leakage prevention through patented emulated technology. Signaling attacks prevented by design.
- Hardware based HID peripherals protection/isolation.
- Tamper Evident Label Special holographic tampering evident labels on the product's enclosure provide a clear visual indication if the product has been opened or compromised.
- All firmware is in ROM (Read Only Memory)
- Unidirectional optical data diodes - Assuring USB peripherals isolation.
- Data flows in one direction only. No reverse data flow possible by design.
- New type of connector DP/HDMI combined connector allows connecting both type of cables - Display Port and HDMI
- Certified for NIAP PP4.0 for PSD. TEMPEST version available (FI11PH-MT). Call 1-877-586-6654 for details.
