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

"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."
"Simple configuration and automatically syncs to the cloud platform."
"It improves because several sensors are deployed within the on-premise environment. It can be very efficient if the customer implements and operates it effectively."
"I definitely recommend Rapid7 InsightIDR."
"I rate Rapid7 nine out of 10 for affordability"
"It improved my organization by building a security alerting program."
"It is a very stable solution."
"The solution is easy to use, and the interface is intuitive."
"The most valuable features in Splunk are the search function and the ability to run selected session reports. The session reports are important because I can use them to see what is going on in our environment weekly. Additionally, we can use the graph to see how often that particular event is happening."
"Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
"UBA, User Behavior Analytics, is a key feature."
"It is the best tool if you have a complex environment or if data ingestion is too huge."
"We did not encounter any issues with scalability. It is almost seamless to add new index (storage) or search (used to analyze the data) nodes to the cluster."
"The most valuable features include the incident review and Dashboard Studio."
"The solution's most valuable feature is its data modeling."
"Scalability-wise, the tool is awesome since you can add or reduce your resources in an easy way."
 

Cons

"Needs a better ability to customize the check within the console."
"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."
"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"The solution's XDR agents cannot compete with the XDR solutions out there yet."
"There are certain limitations with Rapid7 that I am working on."
"Tenable Nessus is easier to deal with. It's more efficient and accurate. InsightIDR is heavier than Tenable in terms of performance and scanning. Rapid7 would be much easier to use if it had a network connector like Tenable. Tenable's connector allows continuous monitoring over the B caps."
"Lacks a mobile application."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
"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 mainly from the user interface regarding the visualizations."
"Splunk has a steeper learning curve, making it feel less user-friendly."
"There are new services which are coming up. If Splunk can catch up with the speed of Amazon, and with the integration, instead of us waiting for another year or so, that would be good."
"Endpoint access is the only issue I can think to mention, even though the endpoint access we have with Cisco is fine."
"Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this."
"Missing capability for audio/video and image processing."
 

Pricing and Cost Advice

"The pricing and licensing are competitive."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"Licensing is by endpoint and amount of retention time (at least ours is). Default retention was one year, but we are able to push the retention further if needed. There's also a provide-your-own-S3 option for longer retention if you don't want to pay for the additional retention years in your Rapid7 agreement."
"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 is good, and it is not very expensive."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"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."
"As a team, we prefer the old pricing model with a perpetual license. We are still evaluating the whole subscription-based model."
"Luckily, we come under a large federal agency, and before the pandemic, they signed a large enterprise license agreement. It worked out great and to our advantage because we are a small organization. We got a 300 gig license, and we just did not have the buying power to be able to get products cheaply. Because we all partnered together under the agency umbrella, we were able to get Splunk Enterprise Security, UBA, and ITSI for cheap. This was good considering the fact that some of these premium apps require a minimum number of users, and we do not have the number of people needed to even justify buying it."
"The pricing modules could be improved."
"Splunk should be able to integrate with other product using the free version."
"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."
"The license for Splunk Enterprise Security is expensive."
"Pricing is pretty fair."
"Setup cost is cheap: It is free, it is user-friendly, and it is fast."

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?
