Helps to deal with potential attacks and is available at a reasonable price
My company has had many benefits from the use of the product in the last eight years. The tool has streamlined our company's incident response process since it serves as a log repository, which allows us to correlate events and access different technology stacks. In our company, we were able to actually find some potential attacks, so it has been very helpful. The tool's integration capability isn't so great. In my company, we managed to integrate it with our Microsoft Azure Subscription, after which we managed to integrate it with other tools. You will face a lot of difficulties if you want to integrate it with your database monitoring tool, PAM solutions, or IAM products. The product has done well overall for my company's teams to deal with their workflow efficiency. I would not recommend the product to others. I rate the tool a seven out of ten.

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

"It's fully scalable. There is no limit. Of course, the license limits per day the number of terabytes. In my opinion, it's very flexible."
"The most valuable feature is the hunting ability to work in a CERT."
"Technical support is very good; they try to resolve issues with the proper SLAs which are defined by them and they understand the client's requirements as well as the client's infrastructure in a better manner."
"NetWitness can be highly beneficial for incident detection and response."
"The most valuable features are the packet decoder, log decoder, and concentrator."
"The most valuable features are the packet inspection and the automated incident response."
"The most valuable feature is the correlation, as it can report in real-time and monitor the management."
"Once it is deployed and you are used to it, you can do whatever you want."
"This is the best SIEM solution on the market comparing to its competitors."
"Once it is setup I think the way the data can be used with in the solution is the best as it allows high customization."
"ArcSight is better than them all when it comes to filtering, normalization, aggregation, dashboards, reporting and correlation, multi-tenancy and custom devices support."
"The real-time analysis adds value."
"It's a reliable service and provides our team members with a lot of knowledge."
"Once the rules are defined, it becomes easy to detect changes and generate automated logs."
"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 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."
 

Cons

"The solution is pretty complex to set up. Comparatively, I have worked on IBM QRadar and Splunk; they are much easier to set up."
"The initial setup is very complex and should be simplified."
"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"The user interface is a little bit difficult for new users and it needs to be improved."
"The threat detection capability and centralizing and upgrading capability need to be improved. The threat alert capability needs to be improved as well because there is some lag time at present. They need to work on their database search too."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"The log system is a bit complex and has room for improvement."
"The initial setup is complex."
"I rate ArcSight three out of 10. I would never recommend it."
"The API integration could be better, and I'd like to see more machine-learning capabilities in the future."
"As of now, if we are evaluating our own scenario, we are not even thinking about it."
"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."
"What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature."
"The correlation and storage have to be improved."
"Technical support has been so frustrating that we've brought in an intermediary, LiveQuest, to deal with HP support for us."
 

Pricing and Cost Advice

"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"We are on an annual license for the use of the solution."
"This is a pricey solution; it's not cheap."
"The licenses are good but the cost is very expensive."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"Compared to the competition, the is price is not that high."
"Our license is for one year."
"The product is expensive."
"Pricing is good, I'd rate the pricing a seven out of ten, with ten being low price. It's better than Splunk and IBM QRadar because their pricing is based on EPS."
"It's a good price, it's one of the cheaper solutions."
"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."
"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."
"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 solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
