Final answer:
In Cortex XDR, the available stitching option is alert stitching, which correlates related alerts into one incident for clearer understanding and efficient response.
Step-by-step explanation:
The stitching option available in Cortex XDR is alert stitching. Alert stitching is a feature that helps in correlating different alerts that may be related to the same incident or attack sequence. By analyzing various indicators of compromise (IoCs) and other relevant data points, Cortex XDR is able to merge related alerts into a single incident, providing a clearer picture of the security event and reducing the number of alerts that analysts need to review manually. This helps in efficient and more effective incident response and investigation processes.
