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.

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."
"This is a great product and the team is very willing to work with companies."
"Rapid7's reporting is more robust than Tenable's."
"Integration with threat modeling from the Metasploit and InsightIDR repositories."
"Simple configuration and automatically syncs to the cloud platform."
"Great coverage of all systems within our network from endpoint to firewall."
"It improved my organization by building a security alerting program."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"I am enjoying our implementation of risk-based alerting. That has helped very much with cutting out a lot of the noise that we have. It has reduced our alert volume significantly. There is about an 80% reduction."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
"With Splunk, we got more insights out of our data as it includes machine and secure data."
"From a visibility perspective, the solution has significantly improved our organization by providing a single platform to visualize our entire IT landscape."
"Splunk allows us to customize processing and dashboards, which helps us take care of our customers' needs."
"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 community marketplace is useful; often, you do not need to rely on Splunk Enterprise Security support due to the wealth of online documentation available—Splunk docs are truly beneficial."
"Exporting is a good feature. It helps me out when I have to do reports. I do a lot of exporting and crunching of the numbers. Dashboards are okay for showing to the leadership, but for doing statistics and updating tickets, the export feature is very beneficial for me."
 

Cons

"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."
"The integration capabilities of the solution have certain shortcomings where improvements are required."
"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."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"One of the things that could be better is digital forensics. It is there, but it can be better."
"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."
"Tenable Nessus is easier to deal with. It's more efficient and accurate. InsightIDR is heavier than Tenable in terms of performance and scanning. Rapid7 would be much easier to use if it had a network connector like Tenable. Tenable's connector allows continuous monitoring over the B caps."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"The administration of the cluster and app deployment to indexers or search heads can be done only using ssh access and command line, there is no GUI tools for that."
"Better education for users would be beneficial as they often don't know what they don't know or how to look for certain features."
"The problem with the product is that the price of Splunk is very high."
"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."
"The price is a significant concern. It is expensive and is designed for enterprise companies, not for small or medium-sized companies."
"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."
"The support and the pricing can be better"
"I have not seen ROI with Splunk Enterprise Security."
 

Pricing and Cost Advice

"The solution has a mid-range price point in the market"
"Rapid7 InsightIDR is priced very well and is cost-effective."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"It is more reasonably priced than other vendors."
"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 pricing of the solution depends on the user. But there is a yearly licensing cost."
"It is a reasonably priced solution."
"The pricing is good, and it is not very expensive."
"Splunk is costly but it’s worth it due to the high-end features."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult."
"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
"The subscription is monthly."
"The license for Splunk Enterprise Security is expensive."
"It's more expensive than the other tools, but it's worth it. Every penny is worth it."
"The Splunk licensing is high."

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?
