A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

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

"The newer 11.5 version that my team is using has found it to have good mapping."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"It's quite economical compared to other solutions in the market."
"The solution is really scalable for the high-end power, enterprise customer."
"NetWitness can be highly beneficial for incident detection and response."
"Offers a good wireless feature."
"The most valuable features are its ingestion of logs and raising of alerts based on those logs."
"The solution is reliable."
"The web logger allows me to view and inquire about various events in real time and is the most useful feature for me because it lets me look at traffic in real time, add filters that remove traffic that is not interesting, narrow down my research to only important traffic, and create reports to evaluate my findings and send information to my customers."
"The most useful features are directories, price, and live reporting."
"ArcSight is very scalable."
"The dashboard is the most valuable feature for us as it can show a lot of information about real-time incidents."
"We do consulting and I get feedback from our clients that the product really helped them with compliance, especially with GDPR."
"It is a robust product and has multiple valuable features, with robust threat intelligence built into its customization and great templates that provide ease of use."
"It's a well rounded product especially with the addition of Logger and Command Center."
"I think that the overall experience with this solution is good, but in particular, I think that the dashboards are quite interactive."
 

Cons

"An area for improvement would be better automation and more inbuilt use cases."
"Advance monitoring and alerting feature is not stable (Event Stream Analysis)."
"It is not so easy to customize this product."
"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."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"The initial setup is very complex and should be simplified."
"I believe they could improve their support, there are often delays."
"The user interface is a little bit difficult for new users and it needs to be improved."
"There are SO MANY things you can do in AS, and there is a lack of really in-depth documentation on a lot of it."
"Technical support should be improved. Many times, I've raised a case but none of them solved it and it took the guys from the Protect724 forum so solve my issue."
"It needs additional and better user customization for SmartConnectors."
"The stability isn't quite perfect. We occasionally run into problems."
"We would like the ability to easily identify either unused resources or those that are being used sub-optimally."
"The correlation and storage have to be improved."
"The solution could be more stable."
"For somebody who is new and just starting with this product, they find it really tough."
 

Pricing and Cost Advice

"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."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"Compared to the competition, the is price is not that high."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"Our license is for one year."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"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."
"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."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"It's a good price, it's one of the cheaper solutions."
"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."
"​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.​"
