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.

Allows for monitoring logs according to industry standards within ESM but has a total capacity capped at 12 TB, limiting real-time data retention periods

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. So, increasing the storage capacity is one area for improvement. Additionally, the real-time data retention is limited due to the 12 TB restriction. Depending on the Events Per Second (EPS) you receive, you might only be able to retain data for seven to ten days. Overall, the 12 TB limit is the main issue we face in terms of maximizing real-time data storage. Moreover, there are a few improvements I would like to see in future releases. My main suggestion for ArcSight is to simplify the deployment process. Currently, the installation process is quite complex. There are various components involved, including transformations, multiple installations, and containerization for various components. Ideally, I'd recommend that ArcSight allow the entire installation, including the ESM and database, to be completed within a single unified setup process for a streamlined experience. Additionally, having readily available and well-organized documentation for the step-by-step installation process would be incredibly helpful. I would also like to see better support.

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."

"The most valuable features of ArcSight ESM are the dashboards, ease of management for anyone, and simple for teams to provide reports related to cyber security. There are a lot of good features that are provided."

"ESM has valuable features for event prediction and security analysis."

"For the typical malware or intrusion, this solution assists us by identifying the symptoms based on network traffic from the application servers."

"It is a vital tool for live monitoring and helps us to understand the traffic alerts of any major issue on the network, thereby reducing hacking attempts."

"ArcSight ESM provides us the flexibility to write our own passwords and customize the solution. It lets us search and log a variety of SmartConnectors. It has 480-plus SmartConnectors."

"The most valuable feature of ArcSight ESM is its ease of use."

"The real-time analysis adds value."

"The user interfaces are quite good and speedy."

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."

"The centralized dashboard for the hybrid cloud environment needs to be more focused. It needs to be redefined because it's missing most of the information. It should be a little bit easy to use. Currently, integration with various applications and connectors is not that easy. Deployment is easy, but integration is not that easy. ArcSight also has a very high bandwidth consumption to pull the local servers. It should have some kind of better process or ability to transfer files from on-premises to the cloud, from the cloud to on-premises, and from a cloud to another cloud."

"The visualization is not very good compared to Splunk."

"In other products, I have found that they use some kind of GUI that is drag and drop. While in ArcSight they use still scripting. They should keep scripting because some people prefer scripting but they should have the option for those who prefer using drag and drop."

"The way that scaling is set up isn't very cost-effective."

"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."

"In certain cases, this product does have false positives, which the company should work on."

"Currently lacks SOAR feature."

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

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

"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."

"The solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."

"HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."

"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."

"Price-wise, ArcSight ESM was a bit high compared to competitors, which factored into our decision to switch to Splunk. It couldn't cover all our business needs for what we wanted to implement."

"It's a good price, it's one of the cheaper solutions."

"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
