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

"The solution's initial setup is easy."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"I like that it's a cloud-based solution."
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"The biggest reason why we chose Rapid7 was to gain value in a really quick time. Its deployment doesn't take months. It just takes a few days."
"The log aggregation and storage provided by InsightIDR has shown no issues with scalability; aggregating over one hundred millions events daily."
"Very intuitive and easy to set up."
"​​User behavioral analytics allows us to pinpoint abnormal or suspicious behavior among millions of events every day."
"The initial setup is really straightforward. It's one of the easiest installations."
"Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
"Compared to IBM QRadar, Splunk Enterprise Security offers faster alert resolution."
"Splunk Enterprise Security is more advanced compared to other solutions, which makes it stand out as a better option."
"It is a very stable solution. I never really had a hiccup with the tool."
"Splunk Enterprise Security offers valuable features like seamless integration and a SQL-standard Structured Query Language for easy searching."
"The Splunk queries are valuable."
"Splunk Enterprise Security offers two valuable features: the Common Information Model and arrangement modules."
 

Cons

"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."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"Rapid7 doesn't integrate well with all our security tools from various vendors, so we plan to switch. Many of our solutions work with Rapid7, but some do not. We are already searching for a replacement already."
"Lacks a mobile application."
"Needs a better ability to customize the check within the console."
"The ability to tune the collector for custom logs would greatly help."
"The product allows us to make only 30 custom rules."
"There is a future in AI with Rapid7, however, it is not fully operated. There are certain limitations with Rapid7 that I am working on."
"The security can be improved."
"If you have to do your own stuff, such as customized charts, it is a little bit more work, but once you're familiar with the Splunk query language, you can pretty much do whatever you want. In terms of features, it should probably have the features that other competitors provide."
"Splunk could enhance its offerings by incorporating modules for network detection and response and fraud management, along with improving its threat intelligence management capabilities."
"The threat detection system has room for improvement."
"I'd say I am happy with the technical support, not elated. They provide great support, but sometimes they don't have the answers that I need."
"I would like additional features in different programming models with the support for writing queries in SQL or other languages, such as C#, Java, or some other type of query definitions."
"We were inundated with the amount of alerts and alarms that we could get out of it. It is also a resource hog and we didn't have the resources to support it on-prem so we're taking it offline now."
"The monitoring aspect of Splunk could be improved. We have to do some queries to get as much information as CrowdStrike or other solutions provide. If you run a big query, you will see a delay. That is the only concern we have because it will take some time if you query large data sets."
 

Pricing and Cost Advice

"It is a reasonably priced solution."
"Rapid7 InsightIDR's pricing is reasonable."
"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 charges us based on the endpoints we connect to."
"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."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"Splunk Enterprise Security is priced lower than competitors."
"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."
"Pricing and licensing are quite high compared to other tools or SIEM tools, but the features justify it."
"The tool's pricing model is great. You can choose between workloads or volume."
"It is expensive, but it is a good tool. It is worth the cost."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"The price can always be lower, but it is fair at the moment. The cost efficiencies depend on the licensing and how much data we are bringing in. We have a fairly large footprint, so it is cost-effective."
"It's more expensive than the other tools, but it's worth it. Every penny is worth 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?
