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

"The UI is very good."
"Great coverage of all systems within our network from endpoint to firewall."
"The solution provides satisfying native integration features"
"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."
"​​User behavioral analytics allows us to pinpoint abnormal or suspicious behavior among millions of events every day."
"The incident case management is the most valuable feature, and the ability to quickly sort through all the logs, network and endpoint data, and add it to an incident case as part of the investigation, with automatic timelining and correlation to other notable events and activities on the network, results in a huge improvement in our overall confidence that we have quickly traced down the right source of an issue."
"Simple configuration and automatically syncs to the cloud platform."
"It gives all the advantages of a SIEM, however, using clever AI, it looks for patterns of behavior rather than just flooding me with all the alerts."
"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security effective."
"Easy to deploy and simple to use."
"It is a very well-organized solution, more user-friendly than ArcSight and QRadar, where I can search and do whatever I need in terms of dashboards, reports, etc., making it the best tool if you have a complex environment or if data ingestion is too huge."
"Splunk is a very good platform for analytics and cybersecurity; we use it very extensively, and it is very easy to use, very stable, and scalable."
"In terms of technical support, we don't have any issues, as the professional services which they have extended to us are very, very good."
"Correlating data across different systems via one interface will allow you to know your environment or identify incident data in ways you never imagined."
"It has a drag-and-drop interface, so you don't need to know SQL or Java to construct a query on Splunk. The resolution time is about the same, but it took longer to discover the issue with ArcSight. Our previous solution took about an hour or more, but Splunk can do it within a few minutes or an hour at most."
"The benefits include the easy integration with other Splunk tools including Splunk UEBA, Splunk ITSI, and Splunk Core. The ease of integration and the organization's experience and familiarity with searching and passing logs through Splunk are the main benefits."
 

Cons

"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."
"One of the things that could be better is digital forensics. It is there, but it can be better."
"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 reporting is the weakest aspect. There needs to be multi-level grouping for events (for example, group by user and destination)."
"Inability to get access to compliance reports within the solution."
"The APIs can be further improved in Rapid7."
"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."
"The ability to tune the collector for custom logs would greatly help."
"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."
"The upgrading process could be smoother."
"It needs integration with a configuration management solution."
"Due to its high licensing cost, Splunk is out of reach for many organizations."
"However, for smaller organizations, the deployment and management can be expensive, leading them to choose other SIEM tools."
"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."
"Sometimes talking through email isn't the most effective method, as they go through troubleshooting steps we've already taken, which requires additional back-and-forth communication."
"The user interface is not user-friendly for non-technical users."
 

Pricing and Cost Advice

"The pricing and licensing are competitive."
"It is more reasonably priced than other vendors."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"The pricing is good, and it is not very expensive."
"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."
"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."
"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."
"Splunk Enterprise Security is expensive. I would rate the cost an eight out of ten with ten being the most expensive."
"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"It is a bit costly."
"Splunk is really expensive compared to all the other tools on the market, including Microsoft Sentinel."
"Free Splunk license for PoCs on personal machines and the ability to scale the PoC to an enterprise level app."
"Splunk should be able to integrate with other product using the free version."

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?
