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.
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

"Losses from security incidents have significantly decreased."
"This is the best SIEM solution on the market comparing to its competitors."
"I really like the correlation part and the way the logs are correlated; I have never faced issues with parsing in this product, and I like the way it parses, and everything is so clear to me."
"The simple fact that HPE ArcSight helped us several times to survive malware attacks (Conficker was one such attack) and it also helped a lot with different compliance audits, which was enough for us."
"ArcSight is a very capable product that integrates with many different platforms."
"We have been satisfied with the support."
"I think the correlation feature is one of the best features of ArcSight."
"If you're looking for a single product that will let you aggregate, correlate and analyze many different sources in a single place, then there are few competitors that can come close to ArcSight's features."
"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."
"Log search allows us to dive deep into aggregated logs and query all event types at once.​"
"I rate Rapid7 nine out of 10 for affordability"
"Rapid7 InsightIDR integrates well with other solutions. It's also easy to configure because Rapid7 InsightIDR has a lot of instructions posted on their website that customers can follow if they need to get the source log."
"Simple configuration and automatically syncs to the cloud platform."
"I have seen that Rapid7 InsightIDR provides security to the networks and endpoints in the company."
"Enables the use of honey pots, honey users, and honey files to monitor for suspicious patterns."
"The log aggregation and storage provided by InsightIDR has shown no issues with scalability; aggregating over one hundred millions events daily."
 

Cons

"Make sure you tune it to your business and infrastructure, which isn't necessarily part of technical support."
"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."
"The stability isn't quite perfect. We occasionally run into problems."
"I tried to learn the syntax in order to customize the software (connectors and agents) for a particular device, and it was a nightmare."
"The visualization is not very good compared to Splunk."
"The user interface of ArcSight Enterprise Security Manager could improve. It is not very good. Additionally, they could integrate the web interface better."
"Support is slow and doesn't always have the required skill set to solve the issues."
"ArcSight ESM is not easy to use and it should be integrated with other tools that have infrastructure capabilities."
"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."
"One thing that springs to mind is easier API integration with ITSMs."
"The integration capabilities of the solution have certain shortcomings where improvements are required."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"The main problem lies in the processes within the client's operating systems."
"I'd like to see a mobile application included and some feature related to the generality of segregation for internal users that access the application."
"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."
"Rapid7's customer support is awful. They didn't respond at all."
 

Pricing and Cost Advice

"There is a license required for this solution."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"Aggregation can help a lot in pushing down licensing costs."
"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."
"The pricing is great compared to others."
"The product licenses are inexpensive."
"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."
"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."
"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."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"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."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"The solution has a mid-range price point in the market"
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"Rapid7 InsightIDR's pricing is reasonable but we have challenges with the Minimum Order Quantity. It is not reasonable for customers who have less than one hundred devices. If they can reduce Minimum Order Quantity, it is good. You have to pay around 5000-6000 dollars per year for the product. The pricing includes maintenance and support costs."
"​Accurately predict your licensing counts as this is a subscription based product.​"
