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

"Their technical support responds quickly and are knowledgable."
"The product has a user-friendly interface and a valuable feature for threat intelligence integration."
"Offers a good wireless feature."
"The most valuable feature is the security that it provides."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"The most valuable feature is the hunting ability to work in a CERT."
"The most valuable features are the packet decoder, log decoder, and concentrator."
"The most valuable feature is the correlation. It can report in real-time and monitor the management."
"We utilize ArcSight ESM for real-time threat detection in our organization. We have custom rules that we've developed on top of the WAN services, along with scheduled licensing activities."
"The most valuable feature is the correlation of different logs that are collected."
"Feature-rich solution which provides better network visibility for improved security"
"The webpage algorithm is the most valuable feature because it was the fastest feature for searching the logs, events, and correlation."
"The real-time analysis adds value."
"Some of the benefits of using this solution are rapid correlation and near-time response on alerts."
"The feature that I have found the most useful is that it can be deployed to the cloud."
"We use ArcSight ESM for log analysis and security alerts. It warns us of threats and then helps us conduct a forensic investigation of a cyber attack or internal incident after it happens."
 

Cons

"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"Its technical support could be better."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"It is not so easy to customize this product."
"Security needs improvement."
"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"The log system is a bit complex and has room for improvement."
"We have encountered issues with unresolved crashes."
"The customer experience could be improved."
"When we need to consume old events, we have to wait for a long time. ArcSight should improve the database capability to reply to queries faster. It would also be interesting if they implemented network visibility. For example, they could add a feature like NetWitness with a model just for looking through the packets."
"The initial setup could be more straightforward."
"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."
"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."
"When I asked our networking juniors for a comparison between LogRhythm and ArcSight, they said that both platforms are almost the same. It is just that LogRhythm is more modern with a digital platform, which probably gives it some advantage over ArcSight. ArcSight is a very old and mature product that is running on an old platform. It is an old legacy platform. In terms of new features, it just requires platform upgrades so that it becomes lighter and easily adaptable, specifically in the cloud. It would be a good thing if they can also make reporting easier."
"Customer service and support is our biggest challenge."
"The product should include a lot more predefined scenarios so the adopted company will have knowledge and a broader skill set in security and network."
 

Pricing and Cost Advice

"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"It is cheap."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"The product price was reasonable for my region and the market."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"It’s cheaper to run virtual machines in a VMware environment."
"This is a pricey solution; it's not cheap."
"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."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"The pricing model is expensive compared to open-source alternatives."
"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."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"The pricing is great compared to others."
"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 is pretty expensive compared with its competitors. I believe that is fine as it provides value."
