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

"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 features are the integration and ease of use."
"The most valuable feature is the hunting ability to work in a CERT."
"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."
"Offers a good wireless feature."
"In my opinion, the solution's most valuable feature is its capacity to monitor network traffic, logs from devices within the network, and network captures. This capability extends beyond logs to include full network capturing."
"I can have enterprise security, email security, next generation firewall security log, HIDS and NIDS logs, etc. all on the same dashboard. It makes it easy to pinpoint or correlate our server to this. I can find out if there is lateral movement. This is the biggest advantage of this solution."
"Support is very good."
"Once the rules are defined, it is capable of detecting minute changes in the systems, which are effectively based on the entries in the log.​"
"It prevented my users from getting infected by ransomware. It can also pinpoint the story behind every virus or network attack to our environment."
"Some of the benefits of using this solution are rapid correlation and near-time response on alerts."
"I value the event correlation of this product."
"The most valuable features of ArcSight ESM are ease of use and readily usable components."
"The solution offers very good monitoring."
"ESM has valuable features for event prediction and security analysis."
 

Cons

"The initial setup is very complex and should be simplified."
"Technical support could be improved."
"More customizability is required, which is something that they need to improve on."
"Lots of competing products have vulnerability protection built into their products, and this solution would be improved by including that support."
"We have encountered issues with unresolved crashes."
"There is no support for this product in this country, so problems have to be resolved through global technical teams."
"The log system is a bit complex and has room for improvement."
"The implementation needs assistance."
"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."
"Its search part can be improved. When I go to the console and search for a few logs or something else, it takes a lot of time. When I try to search for three days or one week, it takes too much time. This is a major area of improvement. I wanted them to include features like SOAR, threat intelligence, and automation, and they seem to have included all these features in version 7.3 or 7.4."
"We would like the ability to easily identify either unused resources or those that are being used sub-optimally."
"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."
"I faced some problems implementing certain attacks, which was my biggest concern. The visualization wasn't very good, and I couldn't create good monitoring dashboards."
"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."
"Deployment typology could be improved. Difficult to scale across all the different lines of businesses."
"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."
 

Pricing and Cost Advice

"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."
"We are on an annual license for the use of the solution."
"The licenses are good but the cost is very expensive."
"It’s cheaper to run virtual machines in a VMware environment."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"It is cheap."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"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 solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"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."
"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."
"​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.​"
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
