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 most valuable feature is the ability to write rules and triggers for network communication and then being able to investigate based on that, where you can see the payload and deconstruct the packets."
"Overall, I feel that the product is very good and my biggest complaint is about their support."
"The product has a user-friendly interface and a valuable feature for threat intelligence integration."
"The most valuable feature is that we can create our own connectors for any application, and NetWitness provides the training and tools to do it."
"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."
"NetWitness can be highly beneficial for incident detection and response."
"Stability has not been an issue with this product."
"The most valuable features are the threat prediction and network forensics."
"ArcSight ESM help customer in Automation for their complex security use case in order to detect the bad guys."
"For the typical malware or intrusion, this solution assists us by identifying the symptoms based on network traffic from the application servers."
"If you know how to work it, and how to configure it properly, then it can give you lots and lots of information."
"ArcSight gives us better visibility into threats that were unknown earlier."
"The most useful features are directories, price, and live reporting."
"The most valuable features of ArcSight ESM are the dashboards, ease of management for anyone, and simple for teams to provide reports related to cyber security. There are a lot of good features that are provided."
"The product's log management and event management capabilities are excellent."
"ArcSight is better than them all when it comes to filtering, normalization, aggregation, dashboards, reporting and correlation, multi-tenancy and custom devices support."
 

Cons

"The user interface is a little bit difficult for new users and it needs to be improved."
"The initial setup was complex because it takes a lot of time to complete the implementation."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions. Whenever any hacking activity or any other threat factor occurred they used to provide the coverages very fast when comparing RSA NetWitness Logs and Packets. I heard the other three solutions, from a discussion with my team members who had experience in other solutions, they used to say that. Whenever any issues happened across the globe RSA NetWitness Logs and Packets are a little bit slow improving those detection mechanisms."
"The solution is pretty complex to set up. Comparatively, I have worked on IBM QRadar and Splunk; they are much easier to set up."
"But the 11.3 version is a complete disaster. You cannot analyze anything."
"The product's licensing models are complex to understand. This particular area needs improvement."
"The product continues to crash. Even with tech support help, it does not resolve itself."
"The initial setup is complex. There are other solutions that are easier to implement."
"The correlation engine effectively connects different events, significantly improving our detection reach. However, limitations exist with non-default alerts, where additional costs arise for integration."
"It's very expensive in its licensing model."
"Best SIEM product but it's high on pricing and licensing."
"The support from ArcSight ESM is very poor. We had a negative experience."
"The solution itself is very scalable, but it is also a lot more expensive than other players."
"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."
"It needs additional and better user customization for SmartConnectors."
"But without continuous tuning of the developed content and improper usage of the product, you can encounter performance issues with ESM/Express, and sometimes hangs, which requires a services restart."
 

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 provides tools to assist in selecting the appropriate license and usage scenarios."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"This is a pricey solution; it's not cheap."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"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."
"It’s cheaper to run virtual machines in a VMware environment."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"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."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"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."
"The pricing is great compared to others."
"The product licenses are inexpensive."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
