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

"Very intuitive and easy to set up."
"The log aggregation and storage provided by InsightIDR has shown no issues with scalability; aggregating over one hundred millions events daily."
"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."
"Enables the use of honey pots, honey users, and honey files to monitor for suspicious patterns."
"I've used other products such as QRadar and other SIEM solutions and I find this solution is much more simplified and user-friendly."
"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."
"Simple configuration and automatically syncs to the cloud platform."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"Manually, it used to take us a whole day to do strong monitoring, now it takes a maximum of two hours because of this product."
"The feature I appreciate the most about Splunk Enterprise Security is Search Processing Language, which has benefited my organization by making searching data a lot easier than other tools I've used."
"The solution's most valuable feature is the dashboard, which allows us to see everything on the same page and provides easy visibility into problems."
"The most valuable features in Splunk Enterprise Security are the cluster capabilities."
"Splunk may be more costly upfront, but in the long run, it saves on time and man-hours."
"Correlation search, in general, is valuable because it allows us to search multiple data sources easily."
"It is very scalable."
"The initial setup is really straightforward. It's one of the easiest installations."
 

Cons

"One thing that springs to mind is easier API integration with ITSMs."
"The integration capabilities of the solution have certain shortcomings where improvements are required."
"I'd like to see a mobile application included and some feature related to the generality of segregation for internal users that access the application."
"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 main problem lies in the processes within the client's operating systems."
"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."
"Customised alert recipients need to be added to allow better first-line action and quicker response."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"We had an instance when Splunk failed and it took us a couple of days to recover."
"There is a free version, but it is insufficient for training and learning because it is a little bit difficult to work with, especially if you are a beginner."
"The use cases provided by Splunk are a good starting point, but could cover many additional topics to ensure that a smaller or less experienced shop might maximize the value of an ES deployment."
"Overall, I don't think that this is a very good product and I don't recommend it."
"It takes time to train people."
"Both quality and speed are lacking. Quality-wise, tickets sometimes go in circles, with unnecessary complications and escalations requiring repeated explanations."
"I do not have any pain points for Splunk Enterprise Security. I am still trying to learn it, but there can be more information on the education side for Splunk Enterprise Security. It would be nice if the certification path was more specific to what I use instead of being so broad."
"I think the pricing aspect of Splunk Enterprise Security is quite high compared to other products, which I hear from most of my customers."
 

Pricing and Cost Advice

"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"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."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"The pricing is good, and it is not very expensive."
"The pricing and licensing are competitive."
"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 more reasonably priced than other vendors."
"It's a yearly subscription."
"The pricing model is expensive and a nightmare based on the amount of data."
"Some of the insights that we have obtained as a part of using Splunk have greatly helped us in increasing our revenue in terms of selling our products."
"Splunk should be able to integrate with other product using the free version."
"Splunk ES is quite expensive compared to some products on the market."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
"The cost is on the high end, which makes it difficult for some organizations to use."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."

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?
