Zuhair Hasan

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.

Senior Security Engineer at Valuepoint Systems

Interpreting data effectively despite challenges in integration and support

If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.

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."

"ArcSight is customizable. You can integrate just about anything. I also like the ease of use."

"Usability is the most valuable feature. The accessibility is quite good."

"There are many features that are good for clients who are looking for a good SIEM solution. They like the ease of creating a business that is effective and impressive."

"On the positive side, ArcSight ESM's performance was excellent. It was very fast when writing queries. It provided good performance monitoring and had built-in rules to show which rules triggered most often and impacted performance. This performance monitoring was well-implemented."

"The correlation feature is good."

"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."

"Stable solution with good customer service support."

"The most important feature is ArcSight's event correlation capabilities. It's powerful and easy. I also like the flex connector capability. It's easy to develop a new connector that isn't fully supported out of the box. For example, say you created a solution internally that's completely different, and it's not unsupported by the solution. You can write your own connector using the flex connector."

More OpenText Enterprise Security Manager pros

Cons

"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 main issue for improvement is the platform's slowness in presenting information. Retrieving information can take a little time when clicking on something."

"They also could improve the product by integrating user and identity behavior analytics."

"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 weakness in this system comes about because, with so many different logs, it is possible that the security analyst will lose information."

"ArcSight ESM could improve the alerts for the storage capacities or actions."

"The tool should improve its UI. It also should make data more searchable."

"The UI interface is somewhat complex and needs to be simplified."

"The roadmap is not clear."

"The customer experience could be improved."

Pricing and Cost Advice

"They have changed the pricing policy. Its price is competitive. Its price is less than half of the price of QRadar, LogRhythm, and Splunk."

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

"It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders."

"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."

"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."

"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."

"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."

"There is a license required for this solution."

"The licensing cost is affordable if you get an enterprise license. The licensing is based on EPS, so you can probably provide a package of license for multiple ESMs with their correlational end fees. It is cost-effective."

"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
