Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.
SohailHyder - PeerSpot reviewer

Has supported compliance needs for mid-sized organizations but lacks customization and advanced integration
If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is. This is where it can improve if we keep in front the feature sets of a complete SIEM solution. Most common in the market is QRadar, but it is depleting now. It has been taken over by some other products such as Splunk and LogRhythm. If we compare these things with Rapid7 InsightIDR, then there are definitely some gaps that need to be filled. Data retention is also one concern because Rapid7 InsightIDR is cloud-based and operates on a subscription model. Whatever data you want to retain, it has to be paid for separately or it has a cost. Other solutions that are on-premises can have their own infrastructure or they provide some data retention for a month or in some capacity-wise, they provide that solution to them which makes them more attractive.

Quotes from Members

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

Pros

"The reports that we are from getting from ArcSight are very valuable. The reporting in ArcSight is good. Our regulators ask us for the reports on a regular basis, and we have been able to provide the required data. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
"The solution offers very good monitoring."
"The stability of ArcSight Enterprise Security Manager is good."
"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."
"Support is very good."
"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."
"The feature that I have found the most useful is that it can be deployed to the cloud."
"The product is quite mature. It's been around for a long time."
"I like the tool's user analysis feature."
"I definitely recommend Rapid7 InsightIDR."
"The product works well. Stability-wise, I rate the solution a ten out of ten."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"Rapid7 InsightIDR is budget-friendly and has a good market position because not everybody can afford to go for LogRhythm or Splunk or QRadar."
"Dashboards, including the main screen, provide much-needed information at a glance, without hours of coding and sifting through logs to find it. In case of an actual security incident, I have faith that insightIDR has retained all logs in a secure manner that prevents log tampering as well."
"Simple configuration and automatically syncs to the cloud platform."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
 

Cons

"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."
"Customer service and support is our biggest challenge."
"ArcSight ESM needs to improve performance, user interface, and automation."
"The customer experience could be improved."
"The API integration could be better, and I'd like to see more machine-learning capabilities in the future."
"The UI interface is somewhat complex and needs to be simplified."
"ArcSight ESM could improve by adding more features and documentation. There needs to be more documentation."
"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."
"The APIs can be further improved in Rapid7."
"The dashboard is an area that could be simplified."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"There is a future in AI with Rapid7, however, it is not fully operated. There are certain limitations with Rapid7 that I am working on."
"The ability to tune the collector for custom logs would greatly help."
"There are certain limitations with Rapid7 that I am working on."
"I would like the ability to adjust the threshold of certain existing alerts. Currently the only option is to change the notifications or create my own alert."
"Inability to get access to compliance reports within the solution."
 

Pricing and Cost Advice

"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."
"HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."
"There is a license required for this solution."
"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."
"ArcSight can be a little bit expensive because of the area that we work in and the cost. Licensing is mostly on a yearly basis, not monthly."
"Aggregation can help a lot in pushing down licensing costs."
"The pricing model is expensive compared to open-source alternatives."
"The product licenses are inexpensive."
"The pricing is good, and it is not very expensive."
"It is a reasonably priced solution."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"Licensing is by endpoint and amount of retention time (at least ours is). Default retention was one year, but we are able to push the retention further if needed. There's also a provide-your-own-S3 option for longer retention if you don't want to pay for the additional retention years in your Rapid7 agreement."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"The solution has a mid-range price point in the market"
"Licensing is straightforward. If, for some reason, you don’t meet the minimum licensing requirements, there is a third-party managed service that can help."
