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

"Integration with threat modeling from the Metasploit and InsightIDR repositories."
"We were able to identify criminals attempting to login from China and put a stop on their IP locations."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"The solution's initial setup is easy."
"I definitely recommend Rapid7 InsightIDR."
"Previously, when something happened, such as when a hacker was attacking one of our customers, we were always behind, or we did not know that we were hacked until the ransomware started, but with the Rapid7 solution, at every step, we could online see what a person was doing, and we could prevent ransomware."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"I've used other products such as QRadar and other SIEM solutions and I find this solution is much more simplified and user-friendly."
"Splunk Enterprise Security comes with 300 pre-deployed use cases that can be easily customized to meet the specific needs of our organization, without the need to purchase additional tools."
"The correlation search functions that generate all the notables are valuable. That can get pretty complicated, and it handles that pretty well."
"The solution's most valuable feature is its data modeling."
"It provides a great range of plugins and one can really take great advantage of utilising inbuilt dashboards to derive the desired monitoring."
"The product is good, it satisfies our customers."
"We have a one stop dashboard for health of some of our services where you can click in and it takes you to other dashboards that have custom near real-time metrics that show the application's health."
"The most valuable features of Splunk Enterprise Security are its high-performance data collection, flexible query language, and its versatility across the organization."
"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."
 

Cons

"Inability to get access to compliance reports within the solution."
"Tenable Nessus is easier to deal with. It's more efficient and accurate. InsightIDR is heavier than Tenable in terms of performance and scanning. Rapid7 would be much easier to use if it had a network connector like Tenable. Tenable's connector allows continuous monitoring over the B caps."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"It takes time for the product's support team to resolve issues, making it an area of concern where improvements are required."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"The main problem lies in the processes within the client's operating systems."
"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."
"Splunk Enterprise Security can be improved by having more focus on the data health monitoring aspect, which will definitely be helpful."
"Splunk Enterprise Security is not exactly user-friendly."
"The historical data extraction needs improvement. I would like the capability of taking data and having it trend longer."
"Operational workflow, use case framework, and ticketing systems need improvement to make it suitable for SOC environments."
"Its user interface for everything other than the charts can be improved."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
"When you get into large amounts of data, Splunk can get pretty slow."
"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."
 

Pricing and Cost Advice

"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"The solution has a mid-range price point in the market"
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"The pricing and licensing are competitive."
"​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 is good, and it is not very expensive."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"It is more reasonably priced than other vendors."
"As a team, we prefer the old pricing model with a perpetual license. We are still evaluating the whole subscription-based model."
"Splunk Enterprise Security is priced lower than competitors."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"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."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"It is quite expensive."
"The tool's licensing is good and we haven't received any complaints from the team handling it."
"Further reductions would be fantastic, and I believe that more and more people would flock to 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?
