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

"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."
"The solution provides satisfying native integration features"
"If you were on other solutions, you would notice that they use agents from third-party, from open-source, from a native OS, or from other tools. Here, however, it is an agent from Rapid7 itself. This adds to the solution's overall capabilities."
"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."
"The alerting to drive investigations and remediation has been its most valuable feature.​"
"I like the tool's user analysis feature."
"The solution is very scalable in terms of the licensing model."
"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."
"The client site login is pretty extensible and probably cost-effective."
"Overall, Splunk is among the top three SIEM tools due to its capabilities and agility in bridging business analytics with security needs."
"Splunk would be my choice for the presentation layer because it comes with inbuilt reports and a dashboard that you can customize."
"Splunk's schema on demand is incredibly useful. I do not have to worry about what my users will need when we onboard their data."
"The best part of Splunk Enterprise Security is its customizable settings."
"Splunk Enterprise Security is a standard solution providing good customer service and partnership."
"I really like the user interface and how it works."
"The site is constantly up, and it's been really easy to adjust the data."
 

Cons

"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"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."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"It would be useful to import threat intelligence in YARA format along with known incorrect email addresses.​"
"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."
"There are certain limitations with Rapid7 that I am working on."
"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."
"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 level of scalability depends on the license you have. You can expand or reduce it based on the environment. It does cost more money to scale, however."
"If possible, we would like to have not only a log monitoring system but a network monitoring feature in this solution as well."
"Customizing our commands should be simpler. Creating custom commands in Splunk requires a long, complex process. For example, we have a command to add all the column data, but we don't have a command to get the average of the column data at the end. It would be useful to have a blank at the end to create our commands and leave the rest to others."
"The ingestion happens quickly, so you can run up the data costs if you use the default settings. It isn't a problem for government agencies in the Saudi market, but many of the corporations in India are small or medium-sized enterprises that cannot afford that kind of ingestion system."
"AngularJS/ReactJS inclusion could be made easier in GUI."
"While Splunk offers SOAR as a separate product, integrating it into the next version of Splunk Enterprise Security as a unified solution would be beneficial."
"I'd like to see more integration with more antivirus systems."
 

Pricing and Cost Advice

"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."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"Rapid7 InsightIDR's pricing is reasonable."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"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."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"I think the price could be improved."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"It is quite expensive."
"I think that most of the monitoring solutions are expensive."
"The pricing modules could be improved."

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.

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?
