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

"We were able to identify criminals attempting to login from China and put a stop on their IP locations."
"The solution is very stable and works very well for what I need it to do."
"The technical support is a solid 10 out of 10 as they take the time to answer any questions or problems which may arise in a reasonable time frame."
"The solution is easy to use, and the interface is intuitive."
"Intelligent alerting to avoid the common problem of alert fatigue associated with traditional SIEMs."
"I like that it's a cloud-based solution."
"The web interface is great — very useful and user-friendly."
"Simple configuration and automatically syncs to the cloud platform."
"Splunk Enterprise Security offers two valuable features: the Common Information Model and arrangement modules."
"You can run reports against multiple devices at the same time. You are able to troubleshoot a single application on a thousand servers. You can do this with a single query, since it is very easy to do."
"While it might be an initial upfront investment on data onboarding, it's going to be something that makes your life incredibly easy once you get beyond that point."
"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."
"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."
"The benefits include the easy integration with other Splunk tools including Splunk UEBA, Splunk ITSI, and Splunk Core. The ease of integration and the organization's experience and familiarity with searching and passing logs through Splunk are the main benefits."
"The product has a good security posture."
"The most valuable feature is the ability to look at threats and link them to the MITRE ATT&CK framework."
 

Cons

"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 integration capabilities of the solution have certain shortcomings where improvements are required."
"Inability to get access to compliance reports within the solution."
"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."
"The main problem lies in the processes within the client's operating systems."
"The APIs can be further improved in Rapid7."
"They should add more configuration and security features to it."
"We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."
"Splunk does not build apps. They only go back and validate the apps that somebody has already built. They should have remote consulting support. They have a wonderful solution. They have 24/7 security. Nobody needs to depend on any third party and will therefore just buy Splunk on the cloud."
"The pricing can be better."
"I would definitely improve the risk-based alerts in Splunk Enterprise Security, helping SOC analysts to get to the drill-down searches."
"The support and the pricing can be better"
"The solution's case management system could be further improved to make it easier for analysts to manage cases."
"Search head clustering is often temperamental in its current state and should be improved, replaced by something better, or be reverted to search head pooling."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
 

Pricing and Cost Advice

"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"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'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."
"It is more reasonably priced than other vendors."
"The pricing is good, and it is not very expensive."
"The pricing and licensing are competitive."
"It is a reasonably priced solution."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
"Our customers often complain that the price of Splunk is too high."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"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."
"Splunk is really expensive."
"It is not cheap."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."

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?
