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

"Prior to implementing the solution, the customers had no visibility of their assets, however, after adopting the solution, they have gained complete visibility over all their assets, including a comprehensive understanding of the network and attack symptoms."
"The detection of ransomware in the internal network has benefited my organization."
"Overall, it is easy to implement."
"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"RSA NetWitness is a SIEM and real-time network traffic solution that collects logs and packets, applies a set of alerting, reporting, and analysis rules on them, and thus provides the enterprise with full visibility of the networks and activities of the systems."
"Overall, this is a good solution with suitable features and it very well fits our needs."
"Technically speaking, this is a good product."
"The most valuable feature of RSA NetWitness Logs and Packets are the alerts and correlations tools."
"The most useful features are directories, price, and live reporting."
"The real-time analysis adds value."
"The product is quite mature. It's been around for a long time."
"It has increased our detective capabilities in the cybersecurity landscape."
"The most valuable feature for us is its ability to correlate security events and then allowing us to take action to address those events."
"It is easy to use when we created some dashboards for analytics."
"ArcSight Enterprise Security Manager (ESM) also gives you the main reason for the alert so it saves time in terms of investigating all alerts, including false alerts, so it improved my company."
"ArcSight was head and shoulders above the rest in features like aggregation filtering, bandwidth, parsing, etc."
 

Cons

"I cannot say that the solution was stable because it tended to crash."
"RSA NetWitness Logs and Packets is far behind the competition."
"Lots of competing products have vulnerability protection built into their products, and this solution would be improved by including that support."
"It is not so easy to customize this product."
"The implementation needs assistance."
"I'd like to see improvement in its ease of use. It's basically unusable. It's overly complex."
"There is no support for this product in this country, so problems have to be resolved through global technical teams."
"We have encountered issues with unresolved crashes."
"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."
"ArcSight ESM is lacking cloud scalable technology."
"The deployment typology could be improved. If you want to scale across all the different lines of businesses, it should be easy to do that and it's not."
"The solution could be more stable."
"HPE ArcSight has a quite steep learning curve."
"​In certain cases, this product does have false positives, which the company should work on."
"There could be more API features for extracting logs on different devices included in the product."
"The tool should improve its UI. It also should make data more searchable."
 

Pricing and Cost Advice

"It’s cheaper to run virtual machines in a VMware environment."
"Compared to the competition, the is price is not that high."
"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."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"It provides tools to assist in selecting the appropriate license and usage scenarios."
"This is a pricey solution; it's not cheap."
"Our license is for one year."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"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."
"Aggregation can help a lot in pushing down licensing costs."
"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."
"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."
"The product licenses are inexpensive."
"The pricing is great compared to others."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
