Bypass Network TAPs
The primary function of the Bypass TAP is to provide fail-proof network access and operation of an In-Line Sensor. In-Line sensors include IPS/IDS, Data Leakage Prevention (DLP), Firewall, Content Filtering, and security devices.
New vulnerabilities are discovered daily. New attack signatures must be added to the In-Line Sensors to address these vulnerabilities. The ByPass TAP is a stand-alone unit separate from the In-Line Sensor. This allows for easy software upgrades or replacement of the in-Line Sensor unit without affecting the Live Network.
The data-path of network traffic in the Bypass TAP is all hardware; this greatly increases the improbability of unpredictable operations as experienced with stacked OS/Software systems. The health of the In-Line Sensor is continually checked by the Bypass TAP via inline heartbeat packets. Heartbeat packets are injected into the In-Line Sensor ports and then as packets are received from the In-Line Sensor these heartbeat packets are decoded. The heartbeats follow a rigorous algorithm that is biased towards maximum network security by allowing traffic to flow through the In-Line Sensor under high traffic and/or packet processing conditions. If the In-Line Sensor is truly failed and not passing traffic, then the Bypass TAP hardware will bypass the In-Line Sensor and allow traffic to flow. In this state, the Bypass TAP continues to test the In-Line Sensor. If the In-Line Sensor recovers, then the ByPass TAP will bring the In-Line Sensor back online.
Bypass TAPs are fully configurable supporting Aggregation, Regeneration, Breakout, and ByPass Modes. Available in Copper 100/1000, Fiber 1Gigabit, 10Gigabit, and coming soon 40Gigabit.
Bypass TAPs are available in the following speeds:
