It supports cloud deployment and is very stable
Pros and Cons
- "The feature that I have found the most useful is that it can be deployed to the cloud."
- "The centralized dashboard for the hybrid cloud environment needs to be more focused. It needs to be redefined because it's missing most of the information. It should be a little bit easy to use. Currently, integration with various applications and connectors is not that easy. Deployment is easy, but integration is not that easy. ArcSight also has a very high bandwidth consumption to pull the local servers. It should have some kind of better process or ability to transfer files from on-premises to the cloud, from the cloud to on-premises, and from a cloud to another cloud."

868,787 professionals have used our research since 2012.
What do I think about the scalability of the solution?
It is not always scalable.
How are customer service and support?
I didn't take any kind of support.
Which solution did I use previously and why did I switch?
I have worked with IBM QRadar. IBM QRadar is very expensive, and it is not easy to deploy like ArcSight. It can't be deployed without an SME. ArcSight is better than IBM QRadar.
How was the initial setup?
The initial setup was very straightforward. It hardly took four weeks.
What other advice do I have?
If you have data centers, an SME or in-house resource to train people, and no budget constraint, then go with IBM. If you have a limited budget, hybrid environment, and untrained manpower, then go for Darktrace, AlienVault, or some other solution.
I would rate ArcSight an eight out of ten.

What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
I rate the overall solution a five out of ten.

Good out-of-the-box rules, but the integration and reporting features can be improved
Pros and Cons
- "The out-of-the-box rules that help us configure functioning rules within the environment are valuable."
- "Customer service and support is our biggest challenge."
What is our primary use case?
We use this solution in our customers company and we deploy the solution on cloud and on-premises.
What is most valuable?
The out-of-the-box rules that help us configure functioning rules within the environment are valuable. For example, they have good resources to help detect and populate the dashboard if something malicious happens. Additionally, we value a good visual representation of a company and network infrastructure.
What needs improvement?
The solution can be improved regarding integration with other security products, ease of implementing some features, and feeling like we're not utilizing the solution as best as we could. In the next release, the solution should incorporate some threat intel features and integrate well with other network solutions, EDRs, palm solutions and the sorts. Additionally, the reporting can be improved to bring out very insightful reports showing senior management value for the solution.
For how long have I used the solution?
We have been using the solution for approximately six months.
What do I think about the stability of the solution?
The solution is stable. I rate it an eight out of ten.
What do I think about the scalability of the solution?
The solution is scalable and has approximately 500 users utilizing it for enterprise businesses.
How are customer service and support?
Customer service and support are one of the biggest challenges we are having. Although it is provided, and once you log tickets, they follow up quickly, sometimes some of the challenges we face drag on for a while because of ironing out specific details about technical support and payments.
How was the initial setup?
The initial setup was a bit complex. Getting things running and configured took a while. Furthermore, some integrations were unavailable, and some had to be custom scripted, so getting the solution up and running was a bit tedious.
What about the implementation team?
We implement in-house, and it takes approximately two months to complete implementation.
What's my experience with pricing, setup cost, and licensing?
The licensing costs are high and the solution is priced through events that come in so the cost tends to be heavy on the client. The price of the license could be lower.
What other advice do I have?
I rate the solution a six out of ten. The solution is good, but its integration and reporting features can be improved. I advise users to have a mature security infrastructure and scale up their technical resources. However, for smaller organizations considering the solution, I advise them to think of other solutions before using ArcSight Enterprise Security Manager.

What is our primary use case?
We have a large footprint of 25 plus subsidiaries reporting into a consolidated security reporting and action team using ArcSight ESM.
How has it helped my organization?
ArcSight ESM has improved our organization because we have better incident reporting. It was originally deployed in order to fulfill compliance requirements. We were required to have security monitoring, ArcSight ESM was a quick and effective way to be able to meet that minimum requirement.
What is most valuable?
The most valuable features of ArcSight ESM are ease of use and readily usable components.
What needs improvement?
ArcSight ESM is lacking cloud scalable technology.
For how long have I used the solution?

ArcSight ESM has average capabilities. It's not seen as being particularly robust or usable for advanced threats.
What do I think about the scalability of the solution?
The scalability of ArcSight ESM is average to poor.
We have approximately 60,000 users using the solution.
How are customer service and support?
The support from ArcSight ESM is very poor. We had a negative experience.
I rate the support from ArcSight ESM one out of five.
Which solution did I use previously and why did I switch?
We did not use a solution prior to ArcSight ESM.
How was the initial setup?
The initial setup of ArcSight ESM was relatively straightforward. The full deployment took us approximately six months. The implementation strategy was to get basic monitoring templates as fast as possible.
What about the implementation team?
We used an integrator for the implementation of ArcSight ESM.
What was our ROI?
The ROI was not important at first because we were trying to cover our basic compliance requirement for monitoring.
What's my experience with pricing, setup cost, and licensing?
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.
Which other solutions did I evaluate?
We evaluated other solutions prior to choosing ArcSight ESM, such as Splunk and RSA NetWitness. We decided on ArcSight ESM because it was cost-effective.
What other advice do I have?

The flex connector lets you develop new connectors to integrate homebrew solutions
Pros and Cons
- "The most important feature is ArcSight's event correlation capabilities. It's powerful and easy. I also like the flex connector capability. It's easy to develop a new connector that isn't fully supported out of the box. For example, say you created a solution internally that's completely different, and it's not unsupported by the solution. You can write your own connector using the flex connector."
- "When we need to consume old events, we have to wait for a long time. ArcSight should improve the database capability to reply to queries faster. It would also be interesting if they implemented network visibility. For example, they could add a feature like NetWitness with a model just for looking through the packets."
What is our primary use case?
We use ArcSight primarily to provide logs for the incident response team and cyber security analysts to evaluate everything happening in the network.
What is most valuable?
The most important feature is ArcSight's event correlation capabilities. It's powerful and easy. I also like the flex connector capability.
