They prevent tool oversubscription by pre-filtering traffic.

They can Tap network links directly, instead of relying on switch [[SpanSPAN port]]s for monitoring access.

Because of their high port densities compared to discreet Taps, they save rack space and power, and can have a lower price per port.

They are fully passive, unable to disrupt network traffic in any circumstances. (Integrated Taps, if present have fail-to-wire on power failure.) This is compared to SpanSPAN ports, where network traffic can be disrupted if the switch is not properly configured while setting up the SpanSPAN port. <ref>[http://www.ebizq.net/topics/business_service_management/features/11496.html?page=1 Integrating Monitoring Access Into The Network Architecture]</ref>
