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

"Simple configuration and automatically syncs to the cloud platform."
"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."
"It improved my organization by building a security alerting program."
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"The technical support is a solid 10 out of 10 as they take the time to answer any questions or problems which may arise in a reasonable time frame."
"The UI is very good."
"The solution is easy to use, and the interface is intuitive."
"Integration with threat modeling from the Metasploit and InsightIDR repositories."
"The flexibility of the search capability is most valuable. You can use it for more than just a basic log aggregator. It is powerful in that regard."
"The solution's newly developed dashboard is pretty amazing."
"They are a good partner for Google Cloud. It provides great visibility, threat detection, and proactive mitigation of risks for our mutual consumers."
"The ability to easily aggregate data and make meaningful reports is what makes Splunk Enterprise Security excellent."
"The best feature I've seen is the ability to easily change the query based on the dashboard or based on the chart we have to create, allowing any value or metric we want to add to that particular chart while keeping the rest of the dashboard settings intact."
"I really like the user interface and how it works."
"The features I appreciate the most in Splunk Enterprise Security are the scheduled alerts and the search function."
"The solution's most valuable feature is risk-based alerting, focusing on building out user risks for individuals throughout the enterprise."
 

Cons

"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."
"Lacks a mobile application."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"Inability to get access to compliance reports within the solution."
"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."
"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."
"If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is."
"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."
"Splunk can improve regex/asset analysis as we do not want to crawl until it is done."
"The way Splunk Enterprise Security could improve is by pulling in and mapping my DHCP data and tracking users' IP addresses as it changes throughout sessions, and being able to keep track of who is actually assigned to what IP address more natively."
"The search could be improved. Now, it is a bit difficult to write search queries because they become quite long, then maintaining those long search queries is a quite challenging."
"Customizing our commands should be simpler. Creating custom commands in Splunk requires a long, complex process. For example, we have a command to add all the column data, but we don't have a command to get the average of the column data at the end. It would be useful to have a blank at the end to create our commands and leave the rest to others."
"The pricing of Splunk Enterprise Security is not very affordable, and I have seen many companies planning to leave because of cost concerns."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
"Splunk can improve its third-party device application plugins."
"The only thing which can be improved is that they are too subjective on whom their Splunk4Good initiative can be applied. They market it as you only need to be a nonprofit, but there is more to it."
 

Pricing and Cost Advice

"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"​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 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."
"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's pricing is reasonable but we have challenges with the Minimum Order Quantity. It is not reasonable for customers who have less than one hundred devices. If they can reduce Minimum Order Quantity, it is good. You have to pay around 5000-6000 dollars per year for the product. The pricing includes maintenance and support costs."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"It's a yearly subscription."
"This solution is costly. Splunk is obviously a great product, but you should only choose this product if you need all the features provided. Otherwise, if you don't need all the features to meet your requirements, there are probably other products that will be more cost-effective. It's cost versus the functionality requirement."
"Pricing is probably its weakest spot. As compared to some competitors, Splunk is really expensive."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"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."
"Splunk's cost is very high. They need to review the pricing. They have to go back and totally readdress the market."
"The pricing of Splunk Enterprise Security 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. 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?
