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

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

"I like that it's a cloud-based solution."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"Integration with threat modeling from the Metasploit and InsightIDR repositories."
"It is a very stable solution."
"I definitely recommend Rapid7 InsightIDR."
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"Dashboards, including the main screen, provide much-needed information at a glance, without hours of coding and sifting through logs to find it. In case of an actual security incident, I have faith that insightIDR has retained all logs in a secure manner that prevents log tampering as well."
"Rapid7's reporting is more robust than Tenable's."
"Technical support and the online community are some of the best for any product."
"The solution is the market leader."
"It helps us to detect viruses and security events from our network."
"It has the ability to correlate data, analyze and review it."
"If properly built, I'm very impressed with the stability of Splunk ES."
"The product has a good security posture."
"The breadth of the data sources that Splunk can ingest data from is broad and deep and it does an exemplary job at handling structured data."
"I am satisfied with the support."
 

Cons

"One of the things that could be better is digital forensics. It is there, but it can be better. They could provide more on the endpoint detection level."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."
"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."
"Needs a better ability to customize the check within the console."
"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 reporting is the weakest aspect. There needs to be multi-level grouping for events (for example, group by user and destination)."
"It'd be really nice if Splunk Enterprise Security had a better and solid configuration guide."
"We are planning to do certifications, and there are many features, such as risk-based score and score detection, where the current training doesn't provide visibility to the analyst. They should offer training based on the features we use."
"Splunk is more expensive than other solutions."
"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be cumbersome."
"Right now, it is too easy for a user to write a query, run it, make it available in polling mode (real-time mode), and bring down the server."
"I want Splunk Enterprise Security to release more AI and machine learning features in the future."
"Their technical support sucks."
"It works as intended for us, and we are getting everything that we need out of it. If anything, its initial setup can be improved a bit."
 

Pricing and Cost Advice

"​Accurately predict your licensing counts as this is a subscription based product.​"
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"The pricing is good, and it is not very expensive."
"The solution has a mid-range price point in the market"
"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 and licensing are competitive."
"It is a reasonably priced solution."
"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."
"Pricing is probably its weakest spot. As compared to some competitors, Splunk is really expensive."
"The tool's pricing model is great. You can choose between workloads or volume."
"Splunk Enterprise Security is an expensive solution."
"Splunk Enterprise Security is expensive."
"It's definitely worth it."
"It is economical than other solutions."
"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?
