MOTASHIM Al Razi - PeerSpot reviewer
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.
Ramnesh  Dubey - PeerSpot reviewer
Allows for monitoring logs according to industry standards within ESM but has a total capacity capped at 12 TB, limiting real-time data retention periods
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. So, increasing the storage capacity is one area for improvement. Additionally, the real-time data retention is limited due to the 12 TB restriction. Depending on the Events Per Second (EPS) you receive, you might only be able to retain data for seven to ten days. Overall, the 12 TB limit is the main issue we face in terms of maximizing real-time data storage. Moreover, there are a few improvements I would like to see in future releases. My main suggestion for ArcSight is to simplify the deployment process. Currently, the installation process is quite complex. There are various components involved, including transformations, multiple installations, and containerization for various components. Ideally, I'd recommend that ArcSight allow the entire installation, including the ESM and database, to be completed within a single unified setup process for a streamlined experience. Additionally, having readily available and well-organized documentation for the step-by-step installation process would be incredibly helpful. I would also like to see better support.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's quite economical compared to other solutions in the market."
"The development of use cases on the SSA console is quite user friendly. This means that the security analyst or the researcher does not have to learn another language."
"Their technical support responds quickly and are knowledgable."
"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 most valuable feature is the security that it provides."
"The most valuable feature is the correlation. It can report in real-time and monitor the management."
"It gives the capability for the incident response team to correlate logs to identify any kind of problem like malware and incidents in a general sense, both for logs and packets."
"The solution is really scalable for the high-end power, enterprise customer."
"Very good real-time reporting with a good dashboard."
"ArcSight ESM allows us to find if someone is doing an administrative operation at inappropriate times of day or trying to do something they're not allowed to."
"On the positive side, ArcSight ESM's performance was excellent. It was very fast when writing queries. It provided good performance monitoring and had built-in rules to show which rules triggered most often and impacted performance. This performance monitoring was well-implemented."
"For the typical malware or intrusion, this solution assists us by identifying the symptoms based on network traffic from the application servers."
"Once the rules are defined, it becomes easy to detect changes and generate automated logs."
"ArcSight gives us better visibility into threats that were unknown earlier."
"The solution offers very good monitoring."
"There are many features that are good for clients who are looking for a good SIEM solution. They like the ease of creating a business that is effective and impressive."
 

Cons

"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
"I believe that integrating the solution with other products such as Oracle would be beneficial."
"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"There is no support for this product in this country, so problems have to be resolved through global technical teams."
"The solution should have more integration capabilities with different platforms."
"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."
"I'd like to see improvement in its ease of use. It's basically unusable. It's overly complex."
"In other products, I have found that they use some kind of GUI that is drag and drop. While in ArcSight they use still scripting. They should keep scripting because some people prefer scripting but they should have the option for those who prefer using drag and drop."
"Deployment typology could be improved. Difficult to scale across all the different lines of businesses."
"ArcSight ESM needs to improve performance, user interface, and automation."
"Could benefit from a more modern interface."
"We would like the ability to easily identify either unused resources or those that are being used sub-optimally."
"It would be nice if the interface were more user-friendly, with, for example, a minimal number of tabs to navigate."
"The user interface of ArcSight Enterprise Security Manager could improve. It is not very good. Additionally, they could integrate the web interface better."
"The initial setup is very complex. We had to architect a deployment which allowed us to incorporate an ever growing number of customers into our hosted instance of ArcSight."
 

Pricing and Cost Advice

"This is a pricey solution; it's not cheap."
"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."
"Compared to the competition, the is price is not that high."
"We are on an annual license for the use of the solution."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"It is cheap."
"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."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"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."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"The product licenses are inexpensive."
"There is a license required for this solution."
"​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.​"
"It's a good price, it's one of the cheaper solutions."
"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."
"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."
