It is a stable solution, but they should make the user interface easier to understand
The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.

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

"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"Offers a good wireless feature."
"The software is scalable to whatever is required, and you can also put a lot of resources in the cloud."
"Performance and reporting are very good."
"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"The most valuable feature is the correlation. It can report in real-time and monitor the management."
"Alerting Module: It provides real-time event processing language on all the logs/packets stream for advanced alerting, i.e., using SQL LIKE statements."
"The most valuable features are the packet decoder, log decoder, and concentrator."
"The most valuable features of ArcSight ESM are ease of use and readily usable components."
"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."
"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."
"The tool is good for correlation and aggregation. We use it as a collection platform."
"The most valuable feature is the correlation of different logs that are collected."
"Customization. ArcSight gives you a platform to on-board out-of-the-box devices with a more accurate way of collecting desired logs/events."
"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."
"Feature-rich solution which provides better network visibility for improved security"
 

Cons

"The tool's integration capability isn't so great."
"It is not so easy to customize this product."
"I believe that integrating the solution with other products such as Oracle would be beneficial."
"Technical support could be improved."
"The initial setup is very complex and should be simplified."
"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"​In certain cases, this product does have false positives, which the company should work on."
"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 stability of ArcSight Enterprise Security Manager (ESM) is not very robust."
"There are several improvements that we would like to see, including: Building a system based on a log collection (SOC), a scenario for external encroachment, and Operator training."
"The tool should improve its UI. It also should make data more searchable."
"The biggest requirement is that there is no cloud solution for this product yet. They need to create a cloud version. It's the biggest thing they can do to make the solution better."
"Micro Focus does not have a physical presence here in Pakistan, although IBM does."
"They also could improve the product by integrating user and identity behavior analytics."
 

Pricing and Cost Advice

"Our license is for one year."
"We are on an annual license for the use of the solution."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"It’s cheaper to run virtual machines in a VMware environment."
"The product price was reasonable for my region and the market."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"Aggregation can help a lot in pushing down licensing costs."
"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."
"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."
"​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.​"
"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."
"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."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
