Inline sensors are deployed directly in the data path and actively examine traffic, allowing them to instantly block malicious traffic. This makes them ideal for use at the network perimeter where quick and decisive action may be necessary to prevent attacks. Offline sensors are not directly in the data path and must be manually configured to collect data, making them less suitable for perimeter use. Passive sensors also do not actively block traffic and are primarily used for monitoring and analysis purposes. Bypass sensors allow traffic to continue flowing even if the sensor fails, making them less suitable for perimeter use where reliability is key.
