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

"Enables the use of honey pots, honey users, and honey files to monitor for suspicious patterns."
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"We were able to identify criminals attempting to login from China and put a stop on their IP locations."
"I definitely recommend Rapid7 InsightIDR."
"The solution's initial setup is easy."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"During simulations or demonstrations, the tool generates alerts, providing details such as the specific application, its origin, and potential threats. For instance, it can identify if an application belongs to a known ransomware group. The system rates the threat, offering a clear detection ratio, such as 97 out of 100. It not only identifies threats but also illustrates the associated behaviors, helping us understand the potential risk to a particular endpoint."
"It improved my organization by building a security alerting program."
"The initial setup is simple, not very complex. Initial deployment takes around 10 to 15 minutes to set up the entire base for Splunk including all three tiers."
"The most valuable feature is that it brings all of the components necessary to identify, analyze, and respond together."
"Its dashboard is valuable. If you have a good knowledge of how to create a dashboard, you can create any dashboard related to cybersecurity. If fine-tuned, the alarms that are triggered for instant review are also very valuable and useful."
"Splunk has helped improve our company's resilience level."
"Out-of-the-box, it seems very powerful."
"Great platform with user-friendly interface and GUI."
"Splunk is stable, and this is why many customers want it."
"Splunk is a user-friendly solution."
 

Cons

"The searching feature in Rapid7 InsightIDR needs to evolve"
"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."
"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."
"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."
"Needs a better ability to customize the check within the console."
"One of the things that could be better is digital forensics. It is there, but it can be better. They could provide more on the endpoint detection level."
"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 product allows us to make only 30 custom rules."
"The solution's automation could be improved."
"Splunk isn't appropriate for smaller companies. It's too expensive."
"Splunk ES could have more pre-built integrations and rules. The detection is fairly accurate, but it depends on the rules you create. Splunk's out-of-the-box configuration isn't that useful."
"The presence of multiple layers creates a significant challenge for monitoring across cloud environments."
"The case management area of the ES could be improved. The ability to move cases through various stages and states. The ability to close a case would be key improvement."
"Their technical support sucks."
"Splunk can improve regex/asset analysis as we do not want to crawl until it is done."
"This solution could be improved by better pricing in general and by easier installation."
 

Pricing and Cost Advice

"The pricing and licensing are competitive."
"It is a reasonably priced solution."
"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."
"The pricing is good, and it is not very expensive."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"Further reductions would be fantastic, and I believe that more and more people would flock to it."
"The Splunk licensing is high."
"Splunk Enterprise Security is expensive. I would rate the cost an eight out of ten with ten being the most expensive."
"Free Splunk license for PoCs on personal machines and the ability to scale the PoC to an enterprise level app."
"Splunk Enterprise Security is an expensive solution."
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable."
"I think we recently switched to the SVC pricing compared to the ingest pricing."

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?
