Featured Reviews

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
Senior Manager at Bank of America
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

"I definitely recommend Rapid7 InsightIDR."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"I like the tool's user analysis feature."
"The web interface is great — very useful and user-friendly."
"The solution's initial setup is easy."
"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."
"The most valuable features have to do with ease-of-use, as it is easy to check the events, investigate suspicious activities, and do forensic analysis, and the web interface is great — very useful and user-friendly."
"Its dashboard is valuable, and if you have a good knowledge of how to create a dashboard, you can create any dashboard related to cybersecurity, and if fine-tuned, the alarms that are triggered for instant review are also very valuable and useful."
"We use the solution as a log collector, and to analyze and provide alerts from the IT instructor."
"Splunk works based on parsing log files."
"It's the completeness of the solution that we like the most."
"The ability to rapidly diagnose problems in production and non-production, across hundreds of log files, is the most valuable feature."
"Positive features include replication capabilities, software development kits, and the architecture."
"There are quite a lot of things that we find useful. Splunk agents are useful and good. Its UI is quite impressive."
"The tool drastically reduces SOC overhead. Its integration with our tool suite is great and helps us correlate events. The solution is also a lot faster than our standalone instances."
 

Cons

"One of the things that could be better is digital forensics. It is there, but it can be better. They could provide more on the endpoint detection level."
"The dashboard is an area that could be simplified."
"Personally, I feel it would greatly benefit from more supported log sources."
"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."
"InsightIDR's integration with other solutions could be improved. Also, I'd like more control from the portal over what's happening on the endpoint side. For example, when I see an attack on an endpoint, I want to be able to stop it from the portal."
"There are certain limitations with Rapid7 that I am working on."
"One thing that springs to mind is easier API integration with ITSMs."
"The ability to tune the collector for custom logs would greatly help."
"Right now, it is too easy for a user to write a query, run it, make it available in polling mode (real-time mode), and bring down the server."
"Most of my interaction is with the user community, which is how Splunk wants it. When I need help, that community is very hit or miss."
"Splunk Enterprise Security could be cheaper."
"The first tier support is as bad as it is most places and getting worse all the time."
"Over time I will have more requirements and I can foresee the solution could improve the search algorithm to run and output the data faster."
"While Splunkbase (the app repository) has a lot of great content, some apps are terribly old and could stand to be updated or purged."
"The user interface is the main area for improvement."
"Most importantly, Splunk can be outrageously expensive. That is the problem with both Splunk and Sentinel. Their pricing literally explodes based on the amount of data you feed in."
 

Pricing and Cost Advice

"​Accurately predict your licensing counts as this is a subscription based product.​"
"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."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"The pricing and licensing are competitive."
"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 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."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"Truly evaluate the data you want to ingest and go slow. Pulling in data that can provide no use to your mission only wastes data against your license."
"Splunk can be an expensive solution. It all depends on how we configure the alerts and the events from the endpoints. You can save some money if you do that correctly. If not, it becomes an expensive solution."
"Its price is fair. Like with anything else, if you go into the cloud, different providers cost more, and you are able to throttle back or throttle up. The cost is comparable with anything else."
"Some of the insights that we have obtained as a part of using Splunk have greatly helped us in increasing our revenue in terms of selling our products."
"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."
"Splunk is costly but it’s worth it due to the high-end features."
"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
"Splunk's cost is very high. They need to review the pricing. They have to go back and totally readdress the market."

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. If you consider SOC outsourcing take your time and find one you can integrate like a virtual team member. They a...

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?
