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 correlation rules and the user platform are most 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."

"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."

"The most valuable features of ArcSight ESM are ease of use and readily usable components."

"We do consulting and I get feedback from our clients that the product really helped them with compliance, especially with GDPR."

"It makes maintenance very easy."

"I am satisfied with the solution's stability."

"ArcSight ESM allows us to find if someone is doing an administrative operation at inappropriate times of day or trying to do something they're not allowed to."

"I value the event correlation of this product."

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

Cons

"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."

"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."

"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."

"They should try to include business logic vulnerabilities in the SIEM tool."

"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."

"The initial setup could be more straightforward."

"Currently lacks SOAR feature."

"The initial setup is very complex. We had to architect a deployment which allowed us to incorporate an ever growing number of customers into our hosted instance of ArcSight."

"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."

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."

"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."

"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."

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

"We're paying a fee for an MSSP, and the cost of the total cost of ArcSight ESM was approximately three to four million dollars a year. The price was less than similar solutions. We did not have additional fees."

"Aggregation can help a lot in pushing down licensing costs."

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

"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."
