It gives better overall visibility. Before, we didn't have a unified system for managing security alerts. ArcSight introduced various alerts, giving us a better visibility of potential problems.

ArcSight is incredibly complex when configuring and deploying, and if your organization doesn't know what they want and what they need, ArcSight will be a challenge for them.
Ramnesh  Dubey - PeerSpot reviewer

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.

The visualization is not very good compared to Splunk.

The correlation engine effectively connects different events, significantly improving our detection reach. However, limitations exist with non-default alerts, where additional costs arise for integration.

The biggest requirement is that there is no cloud solution for this product yet. They need to create a cloud version. It's the biggest thing they can do to make the solution better.

The way that scaling is set up isn't very cost-effective.
Abbasi Poonawala - PeerSpot reviewer
Feb 14, 2022
Deployment typology could be improved. Difficult to scale across all the different lines of businesses.

The only concern is that AI needs to be integrated
Anand-Dutta - PeerSpot reviewer
Jul 4, 2022
What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature. That feature should be more powerful and have more correlation in terms of AI/ML, though MicroFocus has done a good job in adding analytics to ArcSight Enterprise Security Manager (ESM) which has become a big draw to customers. What I'd like to see in the next release of the solution is the addition of AI/ML features.

It is quite complex and could use a better UI. So the improvement would be a simplification. It is pretty complicated to use. The architecture is not complex but the setup and use are.
