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.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
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

"They can subscribe to Rapid7 because it is more valuable and delivers a greater return on investment."
"The solution is very cost-effective because they are not charging based on the EPS but on the number of assets."
"Rapid7 InsightIDR is budget-friendly and has a good market position because not everybody can afford to go for LogRhythm or Splunk or QRadar."
"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."
"The solution is easy to use, and the interface is intuitive."
"The platform offers unlimited storage and agent-based solutions."
"Features for user behavior analytics and the rules for attack review are good."
"It is a very stable solution."
"Splunk incorporates a lot of elements that help to reduce security risks. For it to reach certain compliance, we need to have some security insight. Splunk is a very good SIEM, it’s a top solution, but the best feature is its cost of visibility. We have all the most important features to detect vulnerabilities or risks."
"The features of Splunk Enterprise Security that I find most valuable are the correlation and correlation data."
"Splunk Enterprise Security helps my SOC team prioritize and investigate high-fidelity alerts more effectively by enabling us to quickly gather information, collaborate, and provide various teams with access to the same information, allowing them to follow the workflow to complete the task."
"Splunk Enterprise Security would provide better capabilities and out-of-box detections."
"The solution's most valuable feature is the criticality of alerts."
"It is a great product overall."
"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."
"From my experience, the visual aid that it provides is most valuable. There are charts and other means to provide information."
 

Cons

"There are certain limitations with Rapid7 that I am working on."
"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."
"The searching feature in Rapid7 InsightIDR needs to evolve"
"Rapid7's customer support is awful. They didn't respond at all."
"The reporting is the weakest aspect. There needs to be multi-level grouping for events (for example, group by user and destination)."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"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."
"An area of improvement would be the licensing of the solution. They need a free license, which would allow faster lead times."
"The solution's automation could be improved."
"Many of my clients want to get better at Splunk, but they're afraid of using the tool because they feel it's too complex for them."
"Splunk Enterprise Security can be improved with more ease of configuration. It is pretty straightforward to get it started, however, to really check if my data is all available and how to activate the right use case and the right correlations is still sometimes a hassle."
"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 with better AI integration, improved alert tuning, faster search performance, enhanced automation, and better visualization to understand the data."
"The correlation of events is the most significant challenge I face when using Splunk Enterprise Security for advanced threat detection."
"It currently has limited default rules and customizations. If they can concentrate more on the compliance part and the security information part, it would be helpful."
 

Pricing and Cost Advice

"​Accurately predict your licensing counts as this is a subscription based product.​"
"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."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"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."
"The pricing is good, and it is not very expensive."
"The pricing and licensing are competitive."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"Pricing can be a limiting factor. You have to continuously tune what you are bringing in and make sure what you bring in is of value."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"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."
"The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper."
"It is expensive, but it is a good tool. It is worth the cost."
"The pricing could be made more competitive."
"Splunk Enterprise Security is an expensive solution."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."

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?
