Featured Reviews

SumitKumar20 - PeerSpot reviewer
Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

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.
Nagendra Nekkala - PeerSpot reviewer
A user-friendly solution that can be used to integrate the logs properly with different connectors
ArcSight Intelligence is easy to maintain; one person is enough for the solution's maintenance. The maintenance person will add new features or devices, make policy changes or configurations, and learn and guide other engineers about new threats. ArcSight Intelligence is a user-friendly solution, and users should buy it if their company can afford its cost. Overall, I rate ArcSight Intelligence a nine 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

"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"I would say the most valuable feature of LogRhythm is that it has built-in UEBA functionality, among other basic Windows packages."
"The most valuable features would be the automation, reporting, and the support."
"Alarms are the most valuable feature. We also like the dashboard and how things are at your fingertips. The fact that we can now edit the report templates is going to be a great thing."
"We integrated Azure logs with it and that makes it simpler. Rather than having to log into the portal, we can just check everything in one place. We can compare those to our Windows and host logs to see if any problems correlate between them."
"LogRhythm SIEM's automated response capabilities help organizations mitigate threats through alerts based on specific use cases and monitoring requirements."
"We have NetFlow information going into it, so we can examine a lot of traffic patterns and anomalies, especially if something stands out and is not the baseline. This helps a lot."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"The most valuable features are the integration and ease of use."
"The most valuable features are its ingestion of logs and raising of alerts based on those logs."
"Setting up NetWitness is straightforward. There are multiple connectors, including standard and specialized connectors. One purpose of the connectors is the enhanced capability integrate the custom applications. NetWitness comes with E6 appliances and application images that we use for the initial configurations and for the OS stack information. From there, you can consider the correlation rules, integrate the different log sources, and easily create correlation rules and backlog reports."
"NetWitness Platform is valuable for creating rules that the solution must detect."
"The most valuable feature is the ability to write rules and triggers for network communication, and then being able to investigate based on that."
"The solution is really scalable for the high-end power, enterprise customer."
"NetWitness can be highly beneficial for incident detection and response."
"The most valuable feature of ArcSight Intelligence is a single console where the entire dashboard gives all the connected details in a single place."
"The platform helps us improve threat detection capabilities."
"The ability to tailor an environment to suit our specific use cases is a major advantage of ArcSight compared to other logging servers such as Splunk."
"We found the correlation engine to be very good. It takes logs from different types of devices and does the correlation in a good way."
"The product has a valuable interface."
 

Cons

"There is room for improvement with separate running sources or better integration."
"Scalability-wise, it's not that great."
"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"I would like to see APIs well-documented and public facing, so we can get to them all."
"The initial setup is complex. We are using a LogRhythm partner, at least for the first three years, to help with the monitoring and the deployment of it. We are not a big enough environment where we have people that we can dedicate to it right now."
"The web and on-premise console interface should be the same instead of having a separate engine for each."
"LogRhythm SIEM needs improvement in data grouping and manipulation capabilities."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"Health monitoring of the event sources and devices."
"Lots of competing products have vulnerability protection built into their products, and this solution would be improved by including that support."
"I believe that integrating the solution with other products such as Oracle would be beneficial."
"The solution should have more integration capabilities with different platforms."
"There are instances where you try to run the reports and then it does not give you the desired outcome."
"Security needs improvement."
"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."
"We haven't found the product fully scalable."
"ArcSight Intelligence is a bit slower, and its speed should be improved."
"ArcSight Intelligence's pricing needs improvement."
"The frequency of the updates that we are getting can be improved because the number and types of incidents that are happening at the global level are far more than what we are receiving. The frequency of updates feeds related to our rules should be increased. There should be more frequent information about the new rules that are coming and the global threats that are happening. There should be better options for dashboard creation. At present, the dashboards are good, but there is scope to make them better."
"The dashboard is not user-friendly and is in black and white."
 

Pricing and Cost Advice

"I would rate the tool's pricing around eight out of ten."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"It is a very cost-effective solution."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"This is a pricey solution; it's not cheap."
"It is cheap."
"Compared to the competition, the is price is not that high."
"We have yearly licensing costs. The license fee can be based on the volume of EPS. Some organizations may have, as a gentlemanly gesture, 10,000 EPS and get a 3,000 EPS license but actually use 5,000 EPS."
"It provides tools to assist in selecting the appropriate license and usage scenarios."
"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."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"It’s cheaper to run virtual machines in a VMware environment."
"ArcSight Intelligence is an expensive solution."
"It is an expensive platform."
"The solution is expensive and only suitable for enterprise environments."
"They offer perpetual licenses for the product."
"Its price is average and not very high. Splunk might be a bit cheaper than this. Its licensing is on a monthly basis."
