Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Ease of deployment and cost-effectiveness boost operational efficiency
I have recommendations for increasing dashboard customization. Currently, we are using custom dashboards, but they are not effectively customizable. If they provide better customization options, it would be easier to understand everything in a single dashboard instead of navigating through dropdown menus to see reports. Additionally, log retention is currently 30 days, but some customers request to extend it to 60 days. Having 60 days of log retention would be helpful for maintaining logs.
