How Bypass Technology Works
A bypass TAP, also known as a bypass switch, monitors security devices and instantly reroutes network traffic around any failing tools.


How Do Bypass Taps Detect If The Appliance Is Online?
Bypass TAPs continuously send small test signals, known as heartbeats, to your security appliances.
When your security tool returns these signals, the bypass TAP knows everything is working correctly.
If your security tool stops responding to these heartbeat checks, the bypass TAP redirects network traffic around the problematic device. This happens automatically, without the need for manual intervention.

FAQs
-
The bypass TAP automatically bypasses the tool, ensuring uninterrupted traffic flow.
-
Passive fiber TAPs don’t introduce any latency, and bypass modes add minimal overhead with high-speed switching.
-
Yes. You can deploy identical tools in active/standby mode with automatic failover.
-
Yes. You can implement L2-4 filtering, VLAN tagging, packet slicing, header stripping, and payload masking to ensure your security tools only receive relevant traffic. This significantly improves efficiency and extends their life.
