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

"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."
"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."
"The UI is very good."
"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."
"I definitely recommend Rapid7 InsightIDR."
"The solution is very intuitive, it's easy to set up, is absolutely stable, and has a lot of integration with other security products."
"It improved my organization by building a security alerting program."
"Simple configuration and automatically syncs to the cloud platform."
"Splunk Enterprise Security has positively impacted my organization since everything we do in some form relates back to Splunk, and as a detection engineer, my responsibility is to make sure we're collecting the right information and filtering out the wrong."
"Managing logs is very easy with Splunk Enterprise Security."
"We evaluated several solutions and selected Splunk due to the functionality and cost."
"From the class that I took this week, being able to create notable events from whatever you find in the data set is pretty useful."
"The solution is stable and reliable."
"In my opinion, the best features that Splunk Enterprise Security offers are the RBA part and the fact that you can easily define and develop apps while taking ownership of the tool."
"Its search is very flexible, allowing you to search anything by typing a sentence."
"Now with Splunk Enterprise Security, we have everything in one place—the notables are created automatically, but they can also create their own notables based on the investigation, which improved and reduced about 50% of the manual work that was done before versus what we are doing now."
 

Cons

"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."
"The integration capabilities of the solution have certain shortcomings where improvements are required."
"The dashboard is an area that could be simplified. For management, it should be clear and the files should be there."
"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."
"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."
"InsightIDR is only available in a cloud version. Some of our customers prefer an on-prem solution because they want to manage the security within their environment."
"The ability to tune the collector for custom logs would greatly help."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"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."
"We haven't saved any money with Splunk Enterprise Security. Instead, we have spent excess of the budget on this with unexpected costs."
"The user experience could be improved."
"To improve Splunk Enterprise Security, I suggest incorporating more AI features for faster remediation and enhanced responses, allowing users to build more correlation searches quickly."
"The use cases provided by Splunk are a good starting point, but could cover many additional topics to ensure that a smaller or less experienced shop might maximize the value of an ES deployment."
"We will receive alerts only for the administrators and deployment servers, but not for all servers."
"Technical support services are lacking, especially after you buy the product."
"It'd be really nice if Splunk Enterprise Security had a better and solid configuration guide."
 

Pricing and Cost Advice

"Rapid7 InsightIDR is priced very well and is cost-effective."
"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"​Accurately predict your licensing counts as this is a subscription based product.​"
"The pricing is good, and it is not very expensive."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"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."
"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."
"The variables and the flexibility that Splunk provides are helpful, especially in a hybrid and multi-cloud environment."
"The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."
"The licensing costs are high for Splunk Enterprise Security."
"Splunk can be expensive, as its licensing is based on the daily data ingestion volume."
"Splunk Enterprise Security is expensive."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"Splunk is a bit pricier, but the benefits and ROI are huge."

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?
