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

"InsightIDR helps us investigate an environment to discover information about incidents."
"The solution's initial setup is easy."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"Rapid7 InsightIDR integrates well with other solutions. It's also easy to configure because Rapid7 InsightIDR has a lot of instructions posted on their website that customers can follow if they need to get the source log."
"The incident case management is the most valuable feature. Even though there's always something I find I would like to add to that feature, the ability to quickly sort through all the logs, network and endpoint data, etc., and add it to an incident case as part of the investigation, is nice. Having it automatically timeline that additional data into the original incident timeline, and correlate it to other notable events and activities on the network, results in a huge improvement in our overall confidence that we've quickly traced down the right source of an issue."
"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."
"The alerting to drive investigations and remediation has been its most valuable feature.​"
"Rapid7's reporting is more robust than Tenable's."
"From my experience, the visual aid that it provides is most valuable. There are charts and other means to provide information."
"I like the ease of setting up dashboards on Splunk. They're easy to create, manage, alter, and share. You can fine-tune them any way you see fit."
"Splunk's support is better, and its reporting is easier and better."
"The search lookups are useful."
"The security part is useful as it helps secure the entire environment."
"The solution's most valuable feature is threat intelligence correlations."
"I like the search feature and the indexing. It's very fast and comprehensive."
"The most valuable function is the notable events. When I joined the team, I asked them what they could currently see, and they said nothing. I was pretty shocked. I know for a fact that they're using Enterprise Security or at least they had purchased it. I told them that there are several dashboards within Splunk that we can leverage. There is also notable events where we can see potential incidents or potential alerts about the infrastructure and the network itself."
 

Cons

"The APIs can be further improved in Rapid7."
"Inability to get access to compliance reports within the solution."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"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."
"The main problem lies in the processes within the client's operating systems."
"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.​"
"The solution's XDR agents cannot compete with the XDR solutions out there yet."
"They could offer pre-built search queries for everyday use cases like brute force attacks, DDoS attacks, and other security threats."
"I think the tech support response time could be a bit better. Sometimes I need to wait more than 24 hours for a response to my tickets."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
"One thing that I probably dislike the most about the Splunk product is their support."
"Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported."
"You can run a script from an event, but it needs many clicks to run that integration, which could be made easier."
"Professional support is great, but too expensive."
"The documentation and training resources available for knowledge and training can be expanded. We need to learn more about Splunk Enterprise Security and new security attacks."
 

Pricing and Cost Advice

"The solution has a mid-range price point in the market"
"Rapid7 InsightIDR's pricing is reasonable."
"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."
"It is more reasonably priced than other vendors."
"The pricing and licensing are competitive."
"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."
"The solution is a little expensive."
"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
"I think the price could be improved."
"Splunk is really expensive compared to all the other tools on the market, including Microsoft Sentinel."
"The price is comparable."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"The licensing costs are high for Splunk Enterprise Security."
"The pricing of Splunk Enterprise Security is high."

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?
