Cyber Risk Exposure Management periodically updates the cyber risk algorithm to provide customers with a more accurate, timely, and actionable Cyber Risk Index.

The Cyber Risk Exposure Management team of threat experts continually strives to improve the Cyber Risk Index algorithm to keep up with the evolving threat landscape. Updating risk detection algorithms is a common best practice in the cybersecurity industry. Algorithm updates are applied to all clients but do not affect past risk event scores.
When conducting an algorithm update, Trend Micro threat experts may refine the algorithm to reduce unnecessary score fluctuations caused by relatively insignificant events. Threat experts may also optimize the algorithm by adjusting the relative importance of the following risk type categories:
  • Attack detections
  • Exposure risks
  • Security configuration risks

Algorithm updates can cause your Cyber Risk Index score to increase sharply. Although sudden increases in the Cyber Risk Index can indicate an ongoing cyberattack, increases coinciding with an algorithm update are most likely caused by the algorithm update.
