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 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."
"It improves because several sensors are deployed within the on-premise environment. It can be very efficient if the customer implements and operates it effectively."
"The solution provides satisfying native integration features"
"We were able to identify criminals attempting to login from China and put a stop on their IP locations."
"​​User behavioral analytics allows us to pinpoint abnormal or suspicious behavior among millions of events every day."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"I like the tool's user analysis feature."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"Splunk is a user-friendly solution."
"The most valuable feature is the log aggregation, being able to scan through all of the logs."
"It has a big user base, so the community is useful."
"We can extract the metrics we want on the dashboards. We are able to react to the incidents."
"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."
"It helps us uncover bottlenecks in the network."
"Correlating data across different systems via one interface will allow you to know your environment or identify incident data in ways you never imagined."
"What I appreciate about Splunk Enterprise Security is creating the newest SPL for network traffic and using the risk-based alerting feature that helps my organization by allowing me to learn more information about Splunk every day because it is a big platform."
 

Cons

"The searching feature in Rapid7 InsightIDR needs to evolve"
"One thing that springs to mind is easier API integration with ITSMs. We are evaluating a new ITSM and I would like to have InsightIDR create a ticket when an attack is identified, and the ticket would be closed in InsightIDR when the ITSM resolution is completed. This would take out the "single point of failure" we currently have, if the email recipient is somehow absent, in recording the risk appetite for the incident and the actions taken to mitigate or not."
"Lacks a mobile application."
"The product allows us to make only 30 custom rules."
"They should add more configuration and security features to it."
"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."
"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."
"There are certain limitations with Rapid7 that I am working on."
"Splunk Enterprise Security can be improved by including backup network detection and response and safe management to the paid platform."
"Although the technical support is adequate, there is still room for improvement."
"It could be more user friendly, in terms of the end-user experience."
"The presence of multiple layers creates a significant challenge for monitoring across cloud environments."
"If you have to do your own stuff, such as customized charts, it is a little bit more work, but once you're familiar with the Splunk query language, you can pretty much do whatever you want. In terms of features, it should probably have the features that other competitors provide."
"My company could benefit from doing more Splunk training with Splunk consultants teaching us how to use it."
"Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard."
"The user interface is the main area for improvement."
 

Pricing and Cost Advice

"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"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."
"The pricing is good, and it is not very expensive."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"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 and licensing are competitive."
"It is more reasonably priced than other vendors."
"It can be expensive, especially the licensing costs. However, there is added value in what it can do, not just log aggregation."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."
"It's definitely worth it."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"The pricing and licensing of the product are quite high."
"Splunk's cost is very high. They need to review the pricing. They have to go back and totally readdress the market."
"Splunk ES is quite expensive compared to some products on 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?
