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.
Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Quotes from Members

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

Pros

"InsightIDR helps us investigate an environment to discover information about incidents."
"The product works well. Stability-wise, I rate the solution a ten out of ten."
"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."
"Log search allows us to dive deep into aggregated logs and query all event types at once.​"
"It improves because several sensors are deployed within the on-premise environment. It can be very efficient if the customer implements and operates it effectively."
"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 is easy to use, and the interface is intuitive."
"It improved my organization by building a security alerting program."
"We are much faster finding and addressing issues with Splunk."
"The most valuable feature of Splunk Enterprise Security is website activity monitoring."
"We can automatically suspend or terminate suspicious sessions."
"The features of Splunk Enterprise Security that I appreciate the most include the SPL search."
"The two features I appreciate most in Splunk Enterprise Security are the content management system and the inter-incident review dashboard."
"Support is quick and competent."
"My customer was integrated with many third-party credentials and other threat sources as well. The integration part was seamless and easy. The rates for allocating valuable information and IOCs from different sources are also good."
"I appreciate the integrations with the SOAR architectures and the expandability that can be used throughout the entire ecosystem of Splunk Enterprise Security."
 

Cons

"Lacks a mobile application."
"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 ability to tune the collector for custom logs would greatly help."
"The solution's XDR agents cannot compete with the XDR solutions out there yet."
"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 dashboard is an area that could be simplified."
"Needs a better ability to customize the check within the console."
"There are certain limitations with Rapid7 that I am working on."
"The system can be intimidating, and sometimes the concepts conveyed in the documentation require adjustment."
"While there aren't any major areas where the solution has to be improved, there are certain integrations that are still not available. I would specifically like to see legacy applications integrated."
"Splunk Enterprise Security can be improved with more AI in the commands and more help in the commands, as not all people know how to write code in SPL, and we need more help in this area."
"I think the machine learning should be emphasized. Now, it's really important to analyze Big Data, data mining. A SIEM solution, like Splunk, needs an improved data mining solution, artificial intelligence."
"​Not even Splunk's support guy, who came to our firm, could help with defining proper role management.​"
"The documentation and training resources available for knowledge and training can be expanded. We need to learn more about Splunk Enterprise Security and new security attacks."
"If possible, we would like to have not only a log monitoring system but a network monitoring feature in this solution as well."
"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."
 

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.​"
"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."
"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."
"It is a reasonably priced solution."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"The solution has a mid-range price point in the market"
"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."
"Splunk Enterprise Security is an expensive solution."
"It is quite expensive."
"Splunk Enterprise Security is expensive."
"The cost is on the high end, which makes it difficult for some organizations to use."
"It's a little bit expensive for a small to medium enterprise."
"The licensing is good, but the pricing absolutely needs some work. It is very high."
"I work on the technical side, so I don't know precise figures. However, I know that Splunk is a premium product, so it's somewhat costly. Still, you get a lot of unique features for the money."
"Splunk is not a cheap solution and the license is billed annually."

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?
