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.

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

"The solution provides satisfying native integration features"
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
"The product works well. Stability-wise, I rate the solution a ten out of ten."
"The incident case management is the most valuable feature. Even though there's always something I find I would like to add to that feature, the ability to quickly sort through all the logs, network and endpoint data, etc., and add it to an incident case as part of the investigation, is nice. Having it automatically timeline that additional data into the original incident timeline, and correlate it to other notable events and activities on the network, results in a huge improvement in our overall confidence that we've quickly traced down the right source of an issue."
"Ease of correlation, creating correlation searches are easy and you can combine multiple sources with little effort"
"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."
"The reporting aspect is good and it does what I need it to do."
"My customer was integrated with many third-party credentials and other threat sources as well. The integration part was seamless and easy. The rates for allocating valuable information and IOCs from different sources are also good."
"Its compatibility with other SIEMS is very useful."
"To get visibility from your network devices, servers, and security devices is a great feature."
"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."
"Splunk has machine learning which is a valuable feature."
 

Cons

"The product allows us to make only 30 custom rules."
"The main problem lies in the processes within the client's operating systems."
"The integration capabilities of the solution have certain shortcomings where improvements are required."
"Lacks a mobile 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 InsightIDR is not intuitive to search for logs. It should be more user-friendly and improve the dashboards. We should be able to use ready-made templates instead of having to build one."
"Rapid7 doesn't integrate well with all our security tools from various vendors, so we plan to switch. Many of our solutions work with Rapid7, but some do not. We are already searching for a replacement already."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"Certain sections of the developer documentation could use some updating and clarification."
"I have not seen ROI with Splunk Enterprise Security."
"The solution could use a different licensing model."
"Features related to content management must be improved."
"The tool should include more real-world use case examples built out either through videos or in the community."
"Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported."
"Splunk Enterprise Security can be improved with better triage capability and less dependency on running SPL searches, which would allow analysts who may not have much experience in writing SPL searches to still use the tool and run investigations."
"The product was difficult to back up the first time."
 

Pricing and Cost Advice

"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 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."
"​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."
"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."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"It is a reasonably priced solution."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"Splunk Enterprise Security is expensive but the solution is equipped with a lot of features."
"The licensing model can be expensive, but the value it provides is significant."
"It can be expensive, especially the licensing costs. However, there is added value in what it can do, not just log aggregation."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."
"It's more expensive than the other tools, but it's worth it. Every penny is worth it."
"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."
"The Splunk Enterprise Security license is expensive."

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?
