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
Head Of Cyber Security at Super Secure
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 real-time analysis adds value."
"I value the event correlation of this product."
"We have been satisfied with the support."
"ArcSight gives us better visibility into threats that were unknown earlier."
"The tool sends an automated mail to all the operators, which makes it easy to share the information and reporting.​"
"We use ArcSight ESM for log analysis and security alerts. It warns us of threats and then helps us conduct a forensic investigation of a cyber attack or internal incident after it happens."
"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."
"It prevented my users from getting infected by ransomware. It can also pinpoint the story behind every virus or network attack to our environment."
"InsightIDR helps us investigate an environment to discover information about incidents."
"The UI is very good."
"​​User behavioral analytics allows us to pinpoint abnormal or suspicious behavior among millions of events every day."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"The solution is easy to use, and the interface is intuitive."
"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."
"InsightIDR’s ability to process millions of transactions per day, and to notify me of the most critical ones, is priceless. InsightIDR has the alerts tuned, and has the ability to quickly drill down to determine the threat level."
"It improves because several sensors are deployed within the on-premise environment. It can be very efficient if the customer implements and operates it effectively."
 

Cons

"We have pricing issues. ArcSight ESM may not be the most user-friendly option, and its interface is quite traditional. However, despite these aspects, we find it a good cybersecurity solution. It needs to improve the dashboards, documentation, and support as well."
"It is quite complex and could use a better UI. So the improvement would be a simplification. It is pretty complicated to use. The architecture is not complex but the setup and use are."
"ArcSight is incredibly complex when configuring and deploying, and if your organization doesn't know what they want and what they need, ArcSight will be a challenge for them."
"They need to develop NetFlow appliances that can be installed in the customer network on span ports, collect NetFlow, and send it to ArcSight without relying on the devices' NetFlow capability and their position in the network."
"Sometimes, it takes ages to get an issue resolved. I have ArcSight experience, so I normally try to fix things on my own or find a workaround, but it's tough to get support when I need it."
"The security area has room for improvement."
"We would like the ability to easily identify either unused resources or those that are being used sub-optimally."
"The stability isn't quite perfect. We occasionally run into problems."
"The solution needs improvement in threat intelligence. Increasing the depth of intelligence to help users understand more about threats is a possibility. My suggestion is to expand access to other websites or resources."
"It would be useful to import threat intelligence in YARA format along with known incorrect email addresses.​"
"One thing that springs to mind is easier API integration with ITSMs. We are evaluating a new ITSM and I would like to have InsightIDR create a ticket when an attack is identified, and the ticket would be closed in InsightIDR when the ITSM resolution is completed. This would take out the "single point of failure" we currently have, if the email recipient is somehow absent, in recording the risk appetite for the incident and the actions taken to mitigate or not."
"Lacks a mobile application."
"There are certain limitations with Rapid7 that I am working on."
"Needs a better ability to customize the check within the console."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
 

Pricing and Cost Advice

"​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.​"
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"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."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"The product licenses are inexpensive."
"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."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"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."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"The pricing is good, and it is not very expensive."
"Rapid7 InsightIDR is a cheaply priced product. On a scale of one to ten, where one is very expensive, and ten is very cheap, I rate the product's price at seven or eight."
"The solution has a mid-range price point in the market"
"It is more reasonably priced than other vendors."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"It is a reasonably priced solution."
