Ansar Monideen - PeerSpot reviewer
Provides almost all the SIEM features offered by the leaders at a low cost
Gurucul's data enrichment could be improved. As a security professional, I want to consolidate all these log sources and data to the user, entity, or resource. More advancements are required, especially in enriching security data or attack response. I would like to see more improvements there. The documentation could also be better. Every user and resource has a timeline that lists all the events so we can analyze that particular system and what is happening. We would like to have an option where we can only list the confirmed security threat-related activities for a particular user rather than all activities. This way, we can see what kind of risk is reported for this user and be able to monitor them better.
Ramnesh  Dubey - PeerSpot reviewer
Allows for monitoring logs according to industry standards within ESM but has a total capacity capped at 12 TB, limiting real-time data retention periods
The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible. So, increasing the storage capacity is one area for improvement. Additionally, the real-time data retention is limited due to the 12 TB restriction. Depending on the Events Per Second (EPS) you receive, you might only be able to retain data for seven to ten days. Overall, the 12 TB limit is the main issue we face in terms of maximizing real-time data storage. Moreover, there are a few improvements I would like to see in future releases. My main suggestion for ArcSight is to simplify the deployment process. Currently, the installation process is quite complex. There are various components involved, including transformations, multiple installations, and containerization for various components. Ideally, I'd recommend that ArcSight allow the entire installation, including the ESM and database, to be completed within a single unified setup process for a streamlined experience. Additionally, having readily available and well-organized documentation for the step-by-step installation process would be incredibly helpful. I would also like to see better support.
