The Sensor used in Apex One SaaS is based on how users deploy Sensors:

 
  • The Apex One Security Agent will use the Apex One Endpoint Sensor (SaaS) when enabling Endpoint Sensor via Apex Central Policy.
  • The Apex One Security Agent will use the SecOps Endpoint Sensor when enabling Sensor through TrendAI Vision One™ Endpoint Inventory.

Resource Usage Frequency of sending data Average every 5 minutes Average every 5 minutes Every 5 minutes Every 5 minutes
Average Generated Data 20 MB/agent/day 7 MB/agent/day 8.7 MB/agent/day 6 MB/(agent*day)
Average Network Bandwidth Usage 20 MB/agent/day 7 MB/agent/day 8.7 MB/agent/day 6 MB/(agent*day)
Local telemetry cache size when sensor cannot send data to server 500 MB in memory (50MB) 200MB in memory (200MB)
The agent behavior after the license expired Don't record and send any telemetry data Currently, when the license expires, the sensor still sends telemetry data to the server and stops renewing the required tokens, so the server will no longer receive the telemetry data.

*1 The Apex One Endpoint Sensor (SaaS) supports doing live investigation via diskIOC scan, YARA scan, and registry scan.

*2 The SecOps Endpoint Sensor supports checking present status via remote shell feature.

*3 The Apex One Endpoint Sensor (SaaS) has its own attack discovery detection engine. After Apex One is registered to TrendAI Vision One™, the TrendAI Vision One™ backend server provides detection capability based on recorded activity data.

*4 SecOps Endpoint Sensor doesn't have a detection engine. However, the TrendAI Vision One™ backend service provides detection capability based on recorded activity data.

*5 This is for Windows only and it relies on Apex One EPP.

*6 Apex One Endpoint Sensor (SaaS) is an integrated module of Apex One. If users would like to install Apex One security agent with other EPP products, they have to install the Apex One Coexist agent, not the Full agent. 

*7 The SecOps Endpoint Sensor is a standalone sensor, and it can coexist with TrendAI™ EPP products and 3rd-party EPP products.

Microsoft will default enable the case-sensitive feature after the Windows 10 21H2 update, and Apex One Endpoint Sensor (SaaS) cannot support case sensitivity due to the design specification. It means that users should migrate Apex One Endpoint Sensor (SaaS) to SecOps Endpoint Sensor or they should disable case-sensitive feature to make sure that Apex One Endpoint Sensor (SaaS) can work properly.
