SolarWinds LEM is security information and event management (SIEM) software.
For small companies, Graylog is the best solution possible. It's easy to configure and "just works." Above everything else, it's free. The only thing I hold against it is the fact that it's Linux-based. [This] makes sense because Elasticsearch is Linux-based. But Linux adds a layer of complexity that we don't need for something basic as a logging server. I'm pretty sure that we would have had a logging server years earlier if I had to convince quite a few decision-making people to go ahead with it anyway.
Solarwinds SEM is great for generating reports for investigation purposes. Once you set up the connectors you can walk away and the product runs without needing maintenance. It was however pretty difficult to create the reports and alerts when now starting out and it can be very intimidating for new users.
Graylog does a great job of its core function: log aggregation, retention, and searching.
Graylog has a very flexible configuration. The backend for storage is Elasticsearch and MongoDB is used to store the configuration. You have to option to make your configuration as simple as possible by storing everything on one box, or you can scale everything out horizontally by using a cluster of Elasticsearch nodes and MongoDB servers with several Graylog servers pointed to all the necessary nodes.
Graylog does a good job of abstracting away a fair portion of Elasticsearch index management (sharding, creation, deletion, rotation, etc).
It does a great job of notifying us when accounts have been locked out. We can then find out the device on the network where the login attempt occurred.
Searching for incidents is now a lot faster with the implementation of the HTML 5 interface.
All SolarWinds product suffer from slow response times in management portals. SolarWinds SEM is no exception. While it is much preferred over a "thick client" there is much room for improvement in speed.
If you use the email alert features with SolarWinds make sure to prepare you staff and team for the large amount of emails they could receive. Make sure to reduce the number of alerts so your team does not ignore the alerts.
It is pretty likely that we will renew SEM when the time comes up. It is easy to use and maintain so there isn't much of a need to replace this product. It is also a pretty fair price for the capabilities provided by the SEM
If you are familiar with SolarWinds then you can use this product it's as easy as that. If you have never used a SolarWinds product then it will take a minute to get how they do reports and make dashboards but that being said the tool is great and can make things very easy once you get a feel for how it works and get everything setup how you like it.
Community support does not give simple straightforward answers; simply search up Graylog Issues and look at some of the responses on the forums. The documentation is your only hope if you are on the free version, as you can NOT purchase only support. The few times I have worked with Graylog Enterprise support they were great though.
The quality of support can vary depending on whom you end up speaking with. I was fortunate enough to work with a support representative who was very familiar with the product. He had even authored some of the support documentation on the website. On the flip side, I had two other experiences where I was simply directed to online training material.
In terms of log aggregation, the free product fully stacks up with the competitors listed. Full control over the data ingests for flexible configuration. Graylog even better on that front than AlienVault USM because you cannot configure the variable mapping. We haven't used the threat exchange stuff or correlation. But with regex searches, we have created function dashboards that show threat theater pictures of our network based on logs from our firewall.
Splunk was a pretty good product but the licensing structure needed a lot of work. They changed the structure three times that I am aware and I still had problems understanding LogRhythm had a lot of issues correlating users to IP addresses, the mappings were frequently wrong so this product could not be trusted in my environment as all our access logs are IP based and this needs to be matched to usernames from AD Fortianalzyer is a great product but it can only do logs from Fortigates so that was not helping for anything other than our firewalls.
Graylog is just less expensive than some other options which meant it fit into our budget otherwise we might not be able to justify a higher cost.
Being able to track issues that we normally couldn't track using other tools is a bonus to help us know of any issues we have and can fix before an outage or failure that could potentially cost money.
We have had to spend more time than I would like to understand and customize Graylog which has taken time away from other tasks and projects.
For the price, it produced a decent value. It did a lot of the easy stuff well. I can't give any specific data given the objective of the product was to monitor very basic events in the environment.
