"Message forwarding through the in-built module."
"Open source and user friendly."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"The solution's most valuable feature is its new interface."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"It's basically one of the best SIEM products on the market."
"Splunk is extremely flexible, which allows us to create custom visualizations along with other customizations."
"It has a drag-and-drop interface, so you don't need to know SQL or Java to construct a query on Splunk. The resolution time is about the same, but it took longer to discover the issue with ArcSight. Our previous solution took about an hour or more, but Splunk can do it within a few minutes or an hour at most."
"On the cloud, we are pushing through less than half a petabyte of data. So far, it has been fairly stable because it runs on all the underlying AWS infrastructures."
"It is very simple to tweak or write a small piece of glue code to go ahead and create a new dashboard for a business unit to make near real-time decisions to focus more on other geographies when launching the product."
"The solution helped reduce our alert volume."
"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 ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"Graylog can improve the index rotation as it's quite a complex solution."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"I would like to see some kind of visualization included in Graylog."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"More customization is always useful."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"Lacks sufficient documentation."
"The product was difficult to back up the first time."
"While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
"Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs."
"Splunk has a steeper learning curve, making it feel less user-friendly."
"The solution could use a different licensing model."
"The support that is included with the standard licensing fee is very bad."
"It needs integration with a configuration management solution."
"This is a costly solution."
