Featured Reviews

Zuhair Hasan - PeerSpot reviewer
Manager, Information Technology Security at Nesma
Has good integration capability and provides information and events but improvement is needed in information retrieval speed
The best features are the comprehensive event collection and analysis. Once set up properly, we receive all events and information. The team analyzes our data and presents incidents to us. We can communicate with their team to escalate and resolve incidents. It has a feature we use to search for information about our environment and past incidents. This is very valuable. The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets.

Cloud Security Archirect at IBM
Unified log analysis has strengthened incident detection and supports continuous attack simulation
I do not have any areas for improvement in ArcSight Enterprise Security Manager (ESM) as I have not delved deeply into it; overall, it is a good package. I would like to see the detection and response features included in the next release of ArcSight Enterprise Security Manager (ESM), as security orchestration and automation are increasingly important.

Cons

"They can add behavior analytics and AI or machine learning technology."
"The main issue for improvement is the platform's slowness in presenting information. Retrieving information can take a little time when clicking on something."

"Regarding pricing, I'd say it's in the middle range. Pricing is very good compared to others."

"ArcSight can be a little bit expensive because of the area that we work in and the cost. Licensing is mostly on a yearly basis, not monthly."
"There is a license required for this solution."
