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

"Rapid7 InsightIDR is budget-friendly and has a good market position because not everybody can afford to go for LogRhythm or Splunk or QRadar."
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"The product works well. Stability-wise, I rate the solution a ten out of ten."
"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."
"I have seen that Rapid7 InsightIDR provides security to the networks and endpoints in the company."
"InsightIDR’s ability to process millions of transactions per day, and to notify me of the most critical ones, is priceless. InsightIDR has the alerts tuned, and has the ability to quickly drill down to determine the threat level."
"The feature that I have found most valuable with Splunk is the ability to sift through a bunch of data very quickly."
"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."
"The integration and plugin availability are nice, and the AI module is also great."
"Splunk Enterprise Security is more advanced compared to other solutions, which makes it stand out as a better option."
"Splunk may be more costly upfront, but in the long run, it saves on time and man-hours."
"The solution is very fast and succinct."
"Positive features include replication capabilities, software development kits, and the architecture."
"The stability of Splunk Enterprise Security is very impressive; it is a very stable product."
 

Cons

"One thing that springs to mind is easier API integration with ITSMs."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"They should add more configuration and security features to it."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"The reporting is the weakest aspect. There needs to be multi-level grouping for events (for example, group by user and destination)."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"The APIs can be further improved in Rapid7."
"Data retention can be better. If we want to look at the data for five months or six months, that is not available to us."
"There can be a bit of complexity around some fields during the initial setup."
"Sometimes, the data does not match what we're looking for, or the tool contains incorrect data."
"I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging."
"When deploying Enterprise Security, the biggest challenge or the most amount of work that you're going to spend time on is onboarding your data and getting it into a position that allows you to search it uniformly."
"Sometimes the communication with support happens with multiple staff. They should reduce the time to resolution."
"Search head clustering is often temperamental in its current state and should be improved, replaced by something better, or be reverted to search head pooling."
"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."
 

Pricing and Cost Advice

"Rapid7 InsightIDR is priced very well and is cost-effective."
"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 a reasonably priced solution."
"The pricing is good, and it is not very expensive."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"​Accurately predict your licensing counts as this is a subscription based product.​"
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."
"Splunk Enterprise Security is an expensive solution."
"Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
"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."
"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."
"Further reductions would be fantastic, and I believe that more and more people would flock to it."
"The tool's licensing is good and we haven't received any complaints from the team handling it."

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?
