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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"The correlation rules and the user platform are most valuable."
"ClearSkies is the best for software as a service and small organizations with up to 500 employees."
"The reports that we are from getting from ArcSight are very valuable. The reporting in ArcSight is good. Our regulators ask us for the reports on a regular basis, and we have been able to provide the required data. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
"The most valuable feature is the correlation of different logs that are collected."
"From a daily perspective, ArcSight prevents attacks while it actively monitors our systems."
"ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools."
"The out-of-the-box rules that help us configure functioning rules within the environment are valuable."
"I would rate the ease of use for new users an eight out of ten, with ten being easy to use. It is a good tool."
"We use this product for managed SIEM services and its stability and maturity helps with standard deployments (hardly any surprises)."
"The solution has gone beyond signature-based monitoring and analysis and is AI-powered. It is good enough to cover the full range of cybersecurity services."
 

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."
"They can add behavior analytics and AI or machine learning technology. They also improve their correlation engine. In addition to collecting logs from devices, they can collect the traffic and then correlate these logs and the traffic information."
"The product should include a lot more predefined scenarios so the adopted company will have knowledge and a broader skill set in security and network."
"It needs additional and better user customization for SmartConnectors."
"Unless someone in your organization is an ArcSight SME, you are going to have a difficult time getting answers."
"I must say that tech support is getting worse and worse every year."
"The UI interface is somewhat complex and needs to be simplified."
"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."
"ArcSight's technical support hasn't been as good as it was in the past. I don't find it to be very good."
"There could be more API features for extracting logs on different devices included in the product."
 

Pricing and Cost Advice

"Regarding pricing, I'd say it's in the middle range. Pricing is very good compared to others."
"They have changed the pricing policy. Its price is competitive. Its price is less than half of the price of QRadar, LogRhythm, and Splunk."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"It's a good price, it's one of the cheaper solutions."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"There is a license required for this solution."
"The pricing is great compared to others."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"The pricing model is expensive compared to open-source alternatives."
