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."
"During simulations or demonstrations, the tool generates alerts, providing details such as the specific application, its origin, and potential threats. For instance, it can identify if an application belongs to a known ransomware group. The system rates the threat, offering a clear detection ratio, such as 97 out of 100. It not only identifies threats but also illustrates the associated behaviors, helping us understand the potential risk to a particular endpoint."
"I like the tool's user analysis feature."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
"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 log aggregation and storage provided by InsightIDR has shown no issues with scalability; aggregating over one hundred millions events daily."
"We were able to identify criminals attempting to login from China and put a stop on their IP locations."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"Splunk Enterprise Security helped us with faster detection of threats."
"Splunk stands out for its extensive application integrations."
"I evaluate customer service and technical support as great."
"The feature that we use the most is the correlation search engine within ES."
"The correlation capabilities are the first value that our clients say they like with Splunk."
"Support is quick and competent."
"The solution has made us more secure."
"Without Splunk Enterprise Security, it would be difficult for us to manage and prioritize alerts. There's a potential to lose track of important notifications, and it's essential to our security that we do not miss anything. Splunk has improved our investigations because the reporting and dashboarding make things so much easier. We can provide weekly or monthly reports. I also like Splunk's ability to integrate."
 

Cons

"InsightIDR is only available in a cloud version. Some of our customers prefer an on-prem solution because they want to manage the security within their environment."
"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."
"It takes time for the product's support team to resolve issues, making it an area of concern where improvements are required."
"The dashboard is an area that could be simplified."
"Lacks a mobile application."
"The reporting is the weakest aspect. There needs to be multi-level grouping for events (for example, group by user and destination). Right now, we can do a group by user and a separate table or group by destination. But I'd be more interested in where a person was logging into instead of who was logging in or where he was logging in."
"I feel it would greatly benefit from more supported log sources."
"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."
"The on-premise integration with SOAR could be more simple; the cloud version integrates with SOAR very easily, but the on-premise SOAR and on-premise Splunk Enterprise Security are really not that easy, so I would appreciate if that could be improved."
"Splunk could enhance its services by providing more comprehensive professional assistance aimed at optimizing our investment."
"Its deployment is difficult. I remember when I first started learning, I faced several challenges, especially when deploying VMware in a virtual environment."
"Splunk should have more regional data centers in the Middle East."
"Its search or filtering capability is nice, but it can be improved. It is currently a bit complicated, and it should be simplified. If we can write the search filter in a more simplified way, it would be better."
"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations."
"It is important to make sure that everything is built off of the threat models and all the underlying items within Splunk."
"Splunk Enterprise Security can improve in terms of probably being able to talk to additional sources."
 

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."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"It is more reasonably priced than other vendors."
"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."
"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"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 on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"Pricing is pretty fair."
"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"Splunk Enterprise Security is expensive but the solution is equipped with a lot of features."
"The Splunk Enterprise Security license is expensive."
"It is economical than other solutions."
"Splunk Enterprise Security is a bit expensive overall, but it provides good value."
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."

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?
