Centralized threat hunting has improved alert accuracy and simplifies incident investigations
I would say there are two areas for improvement: the reporting dashboard that provides insights or reports weekly or monthly lacks detailed information about how logs are being ingested. While the details are there, they could be more concise and easier to understand for any level of authority. The second area is alert tuning; compared to Microsoft Sentinel, Rapid7 InsightIDR provides fewer alerts with more static alert functionality and lacks dynamic alerting exposures. There could be improvements to learn from past alert activities for more dynamic alert configurations. These two areas are the main areas for improvement; everything else is good.

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

"If you were on other solutions, you would notice that they use agents from third-party, from open-source, from a native OS, or from other tools. Here, however, it is an agent from Rapid7 itself. This adds to the solution's overall capabilities."
"I've used other products such as QRadar and other SIEM solutions and I find this solution is much more simplified and user-friendly."
"I like the tool's user analysis feature."
"I have seen that Rapid7 InsightIDR provides security to the networks and endpoints in the company."
"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."
"Integration with threat modeling from the Metasploit and InsightIDR repositories."
"The biggest reason why we chose Rapid7 was to gain value in a really quick time. Its deployment doesn't take months. It just takes a few days."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"Splunk is powerful when sorting huge amounts of data."
"Splunk Enterprise Security helps me detect threats faster depending on the type of log I'm using. If I have a current company's log, I can easily detect it faster."
"The technical support is among the best in the market."
"UBA, User Behavior Analytics, is a key feature."
"Correlating data across different systems via one interface will allow you to know your environment or identify incident data in ways you never imagined."
"The ability to view all of these different logs, then drilling down into specific times or into specific data sources, has proved to be the greatest aspect in decreasing our troubleshooting overhead time."
"The best advantage is that Splunk Enterprise Security helps our organization collect and analyze logs from multiple systems in one place, providing real-time monitoring, faster threat detection, and quick incident response and investigations that improve security visibility, reduce response times, and help our team make better decisions."
"Summing up everything from a SIEM and security point of view, I think Splunk is by far the best product that I have been using since my work experience."
 

Cons

"The product allows us to make only 30 custom rules."
"The dashboard is an area that could be simplified. For management, it should be clear and the files should be there."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"The integration capabilities of the solution have certain shortcomings where improvements are required."
"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."
"I chose eight out of ten because of the analytical rules; they lack dynamic rules, and also due to the dashboard and reporting part."
"Splunk is on the right path. It's good, but it does not provide everything that we need."
"Its initial setup is complex. You're going to need deployment services from somebody who is an expert in the product."
"The user interface is not user-friendly for non-technical users."
"Splunk Enterprise Security is great but can have some frustration points. It can sometimes be slower to use."
"I would like to see future development in terms of ML (Machine Learning)."
"DMC should be a little more intuitive with better dashboarding. Seeing the cause of data flow can be tough to track down."
"The product was designed for security and IT with business intelligence needs, such as PDF exporting, but this has not been the highest priority. While the functionality is there, it could be developed more."
"The price of the solution could be cheaper."
 

Pricing and Cost Advice

"​Accurately predict your licensing counts as this is a subscription based product.​"
"Rapid7 InsightIDR is priced very well and is cost-effective."
"It is a reasonably priced solution."
"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."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"I have no opinion on pricing."
"The solution is costly."
"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."
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."
"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."
"My customers have found the price of the solution to be high."
"From what I have seen so far, Splunk has multiple cost models. The one that we are using is pretty good when it comes to ingesting data into the environment. It has worked out pretty well."

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?
