Providing comprehensive insight into alerts while working towards AI enhancement
I definitely recommend Rapid7 InsightIDR. It is becoming better, with improvements being continuously made to the product. Right now, I do not have any advice about Rapid7 for other users because every organization or user has different criteria or multiple use cases, so I refrain from commenting on that. I rate the overall solution seven out of ten.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Great coverage of all systems within our network from endpoint to firewall."
"Very intuitive and easy to set up."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"The UI is very good."
"The solution's initial setup is easy."
"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."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"The web interface is great — very useful and user-friendly."
"The initial deployment was straightforward."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
"The level of robustness on offer is very good."
"The solution's most valuable feature is its data modeling."
"Support is quick and competent."
"We can present to our management in real time the security of the batch management for the PCs, security regarding the network equipment. We're currently working in the Azure Cloud project, so we can send any logs from the cloud to Splunk. We can monitor them and we can present to the managers and customers. It's a very good solution for reporting. We use Splunk for reporting and monitoring of any solution in the company."
"The ability to rapidly diagnose problems in production and non-production, across hundreds of log files, is the most valuable feature."
"The most valuable features of the solution are it is straightforward to use and the documentation is good for finding out how to get the data you are looking for."
 

Cons

"Rapid7 InsightIDR is not intuitive to search for logs. It should be more user-friendly and improve the dashboards. We should be able to use ready-made templates instead of having to build one."
"InsightIDR's integration with other solutions could be improved. Also, I'd like more control from the portal over what's happening on the endpoint side. For example, when I see an attack on an endpoint, I want to be able to stop it from the portal."
"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"The APIs can be further improved in Rapid7."
"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."
"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."
"It would be useful to import threat intelligence in YARA format along with known incorrect email addresses.​"
"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."
"You do need a lot of training and certification with this product."
"Its reporting can be improved. That's the only complaint I have heard. I don't need the reporting part, but I know that other people in the organization need it."
"I've never had too many issues with the stability. Years ago we had indexes crash but that was more on us. We didn't understand how to properly size Splunk."
"The tool should include more real-world use case examples built out either through videos or in the community."
"I would like to see the asset and identity lookups be more automatic and less manual."
"A lot of people are averse to using new tools so if they make it even more user-friendly than it already is, I think that could go a long way."
"Although the technical support is adequate, there is still room for improvement."
 

Pricing and Cost Advice

"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"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."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"The pricing is good, and it is not very expensive."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"​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."
"Expensive compared to other options."
"While Splunk is more expensive than other solutions, we would still choose it because of its capabilities."
"The pricing modules could be improved."
"My customers have found the price of the solution to be high."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"Splunk has always been on the expensive side."
"Splunk is really expensive compared to all the other tools on the market, including Microsoft Sentinel."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."

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?
