Featured Reviews

Gabriel R. Sousa - PeerSpot reviewer
Consultor De Informação Plena at Protivity Brasil
Centralized logging has provided full security visibility and supports faster incident investigations
I think one of the positive points Graylog Enterprise offers is this centralization of logs, which greatly facilitates investigation work. Another point is its ability to perform searches, apply filters, and run queries so that you can look for a specific event, user, or IP. I think Graylog Enterprise brought efficiency gains because when you run a search or do some research, you can save it, so you do not need to enter the query again; you just retrieve what is already saved. I think the main point regarding Graylog Enterprise features is that it helps a lot in event analysis and identification because it brings in a lot of logs and a lot of information, so you can access all the information about the alert there. I believe Graylog Enterprise's AI features are very good, allowing you to use AI to run specific searches, which brings a lot of results. Regarding the AI features of Graylog Enterprise, I did not use them in such depth as to accurately evaluate their reliability, but I believe that AI can help speed up analysis and identify some suspicious patterns, though it is important that the result is always validated by an analyst.
