Centralized threat hunting has improved alert accuracy and simplifies incident investigations
I would say there are two areas for improvement: the reporting dashboard that provides insights or reports weekly or monthly lacks detailed information about how logs are being ingested. While the details are there, they could be more concise and easier to understand for any level of authority. The second area is alert tuning; compared to Microsoft Sentinel, Rapid7 InsightIDR provides fewer alerts with more static alert functionality and lacks dynamic alerting exposures. There could be improvements to learn from past alert activities for more dynamic alert configurations. These two areas are the main areas for improvement; everything else is good.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"The UI is very good."
"Log search allows us to dive deep into aggregated logs and query all event types at once.​"
"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."
"Dashboards, including the main screen, provide much-needed information at a glance, without hours of coding and sifting through logs to find it. In case of an actual security incident, I have faith that insightIDR has retained all logs in a secure manner that prevents log tampering as well."
"Integration with threat modeling from the Metasploit and InsightIDR repositories."
"The solution is very intuitive, it's easy to set up, is absolutely stable, and has a lot of integration with other security products."
"The solution's initial setup is easy."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"In my experience, Splunk Enterprise Security detects incidents approximately 20% much faster than other tools."
"Splunk is one of the most powerful SIEM platforms due to its flexibility, scalability, and advanced search capabilities as it uses the SPL language."
"The ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"The unique and most valuable feature in Splunk Enterprise Security is the correlation capability and the SPL query language itself."
"The feature I appreciate the most about Splunk Enterprise Security is Search Processing Language, which has benefited my organization by making searching data a lot easier than other tools I've used."
"We are saving a lot of time by being in one place instead of several servers."
"The solution has made us more secure."
"Threat detection in Splunk Enterprise Security is more than 60 to 70% faster compared to other tools."
 

Cons

"I would like the ability to adjust the threshold of certain existing alerts. Currently the only option is to change the notifications or create my own alert."
"Rapid7's customer support is awful. They didn't respond at all."
"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."
"If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is."
"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."
"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 chose eight out of ten because of the analytical rules; they lack dynamic rules, and also due to the dashboard and reporting part."
"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."
"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."
"From a pricing perspective, the costs have become higher, as I understand from our procurement team."
"The integration with all our tool sets felt like we were reinventing the wheel, which was a pain point for us."
"Splunk is not very user-friendly. It has a complex architecture in comparison to other solutions on the market."
"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."
"A few years ago, I would have definitely recommended Splunk, but nowadays, better alternatives are available."
"The most significant challenges I face when using Splunk Enterprise Security for advanced threat detection are the false positive alerts."
"Splunk Enterprise Security can be improved with additional features and newer features and tools."
 

Pricing and Cost Advice

"The pricing and licensing are competitive."
"It is more reasonably priced than other vendors."
"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."
"The solution has a mid-range price point in the market"
"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."
"The pricing is good, and it is not very expensive."
"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."
"Splunk is really expensive."
"The licensing model can be expensive, but the value it provides is significant."
"Its pricing model can be improved."
"Splunk is a bit pricier, but the benefits and ROI are huge."
"Splunk Enterprise Security is an expensive solution."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"Splunk should be able to integrate with other product using the free version."
"I think that most of the monitoring solutions are expensive."

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?
