Risk Index
|
A comprehensive score based on the dynamic assessment of risk factors inclusive of
exposure, attack risk, and security configurations risk
You can take company-wide remediation steps and preventive measures to lower the
company-wide risk index over time.

Risk Summary
|
A monthly summary of your company's risk scores related to exposure, attack, and security
configuration
|
|
Attack Surface
|
A representation of the attack surface of your company's devices
-
Device Estimate: The total number of devices identified by data sources and additional
devices added by the administrator that are not connected to Trend Micro Vision One
Click Update Estimate to specify the total number of endpoints
you believe are part of your environment (including devices discoverable by network
discovery).
Tip:
Estimating the total number of devices in your environment helps identify the gap
between devices visible to Trend Micro detection and security, and the actual attack
surface you need to protect. Your estimate should include all devices in your
environment, including devices managed by Trend Micro agents.
-
Discovered Devices: The level of visibility into device health for the devices connected
to Trend Micro Vision One
-
Full: Devices managed by Trend Micro agents
-
Partial: Devices not managed by Trend Micro agents but that have identifiable metadata
(for example, host name and device name) AND that send activity data through non-agent
data sources (for example, Trend Micro Vision One Network Sensor or Azure AD).
-
Limited: Devices not managed by Trend Micro agents but that have identifiable metadata
(for example, host name and device name) OR that send activity data through non-agent
data sources (for example, Trend Micro Vision One Network Sensor or Azure AD).
Click Extend Visibility to add asset visibility data
sources.
-
Device Can Be Assessed for Risk: The assessed risk level of devices based on unpatched
vulnerabilities, system configurations, and internet accessibility
Click Extend Risk Assessment Scope to add asset
exposure data sources.
-
Devices with Managed Agents: The risk level of devices managed by Trend Micro agents
Click Improve Security to add managed security data
sources.
Tip:
Attack surface discovery continuously identifies known and unknown assets in your
environment to inform your attack exposure, and security configuration. Visibility improves
as you integrate more Trend Micro sensors and third-party data sources.
