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.
Sathis-Kumar - PeerSpot reviewer

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"​​User behavioral analytics allows us to pinpoint abnormal or suspicious behavior among millions of events every day."
"The technical support is a solid 10 out of 10 as they take the time to answer any questions or problems which may arise in a reasonable time frame."
"The solution is very stable and works very well for what I need it to do."
"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."
"It gives all the advantages of a SIEM, however, using clever AI, it looks for patterns of behavior rather than just flooding me with all the alerts."
"Great coverage of all systems within our network from endpoint to firewall."
"The alerting to drive investigations and remediation has been its most valuable feature.​"
"There are quite a lot of things that we find useful. Splunk agents are useful and good. Its UI is quite impressive."
"The solution allows easy gathering and ingestion of the data."
"The most valuable features are how stable and easy to use Splunk is."
"When we use a centralized log monitoring system we can see things on the dashboard and it is easier for the IT manager or an IT engineer to take corrective action in the system."
"Since Splunk is a platform for data, we can ingest and correlate data from virtually any type of system."
"The most valuable features of Splunk Enterprise Security are reporting capabilities. It is a good tool for checking systems and analyzing situations. I find it useful to check my systems and analyze situations."
"The data analysis part is good in Splunk, which is something that I like the most, and it is also quite easy to use, with dashboards, visualizations, and analytics that are good."
"It helps streamline troubleshooting and log analysis."
 

Cons

"The dashboard is an area that could be simplified. For management, it should be clear and the files should be there."
"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."
"The APIs can be further improved in Rapid7."
"One thing that springs to mind is easier API integration with ITSMs."
"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 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."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"The searching feature in Rapid7 InsightIDR needs to evolve"
"Delays in responses from the technical team can pose challenges for both vendors and clients, especially considering that Splunk applications and machine solutions are critical assets."
"The security can be improved."
"The user interface feels clunky to navigate and interact with in Splunk Enterprise Security compared to other case management solutions where it feels easier to use at a high level."
"For on-premise, it's more about optimization. With such a heavy byte scale of data that we are operating on, the search for disparate data sometimes takes about a minute. This is understandable considering the amount of data that we are pumping into it. The only optimization that I recommend is better sharding, when it comes to Splunk, so that data retrieval can be faster."
"It requires a significant amount of relatively complex architecture once you push past the single server instance."
"The first thing that comes to mind is a little bit of UI improvement. It sometimes can be a little bit buggy or it can be a little bit slow, but that varies from customer to customer."
"Index performance is a bit slow but this is partly due to the huge volumes of data for our industry within our environment."
"The documentation and training resources available for knowledge and training can be expanded. We need to learn more about Splunk Enterprise Security and new security attacks."
 

Pricing and Cost Advice

"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."
"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"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 more reasonably priced than other vendors."
"The pricing and licensing are competitive."
"The solution has a mid-range price point in the market"
"​Accurately predict your licensing counts as this is a subscription based product.​"
"Splunk ES is quite expensive compared to some products on the market."
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."
"Our ROI is high."
"The pricing could be made more competitive."
"As a team, we prefer the old pricing model with a perpetual license. We are still evaluating the whole subscription-based model."
"While Splunk is more expensive than other solutions, we would still choose it because of its capabilities."
"Splunk Enterprise Security is affordable."
"The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper."

For tools I’d recommend: -SIEM- LogRhythm -SOAR- Palo Alto XSOAR Doing commercial w/o both (or at least an XDR) is asking to miss details that are critical, and ending up a statistic. Also, remember that any EDR/XDR should integrate to the SIEM/SOAR and a strong threat intel source.

I haven't used these big-name ones like Splunk etc. but I feel they're overpriced. I think they charge an arm and a leg for each module. The ROI justification is not there. Why not try a cheaper and robust alternative like Elasticsearch?
