Graylog vs. Splunk Enterprise Security

If you already have a basic understanding of Elasticsearch and/or MongoDB, Graylog will be a great fit when it comes to log aggregation. It will be a decent option even if you don't have any experience but have the time and willingness to roll up your sleeves that learning those tools will require. Graylog supports plugins to extend functionality for things like SNMP traps, telemetry collection, and solar flares. As is the case with most software with plugins, if the core functionality for which you are looking (i.e. not logging) is based on a plugin, Graylog probably isn't for you. The majority of the plugins in the marketplace are developed by third-parties looking to solve their specific use case so bug fixes and new features are not a given.

Well suited: Splunk ES is highly recommended in an environment with many data sources and experienced computer engineers. It has a steep learning curve, but once that hurdle is crossed, it is absolutely a beast. It is also very expensive, so a company putting a high amount of budget in Security is needed. Not well suited: Splunk ES is not recommended if a company has only a few sources and some non-technical IT users. The price won't justify the fewer data sources and scratching just the surface level. Moreover, non-technical IT users would be better off with something that has a query builder, unlike Splunk.

• Very fast process of hugh amounts of information
• Easy to built dashboards with rich visual display
• Intuitive filter string auto-complete
• Alerts based on differents scenarios and triggers

• Its best feature is its user interface, which is easy to navigate and understand. All you need is a little tutorial on how to use the Splunk query language and you're done.
• Logs can be easily uploaded or shared across multiple platforms and display a highly insightful graphical representations of data using graphs, tables, and many other formats.

• Configuration can be hard to understand
• More quickly and easy ways to search for data
• Auto-categorization of log entries would be excellent

• ES on the cloud (SaaS) has too many limitations with platform administration.
• Supported integrations are not always on par with enterprise support especially when dependent on 3rd-party proprietary APIs.
• In later versions, unforeseen glitches seem to show up that have no resolution except version upgrade. This used to not be the case in prior versions which were very stable.

We are very happy with Splunk and would advise anyone to take a serious look at it. It might look pricey but the rewards Splunk offers seem endless.

Graylog is more on the technical side of user interface, with a steep learning curve that can be challenging for non-tech people. Once its logic is understood, however, its great to use and people have no issues to find the information they need. It's configuration is also not that easy, however this we consider impossible to avoid in spite of the type of service it does

Maintaining hundreds or even 1000+ SOC use cases is really difficult, considering that the Data sources may not always send the data. A module that detects data freshness issues and detect data format changes would be a great help. the main challenge today using Splunk Enterprise Security is making sure that the detection rules are still working properly given all the changes that occur in data source applications. Also, maintaining the data collects on tens of thousands of servers and more than 100k workstations is a real company IT challenge: the splunkbase forwarder may not support old OS anymore, while these are the most important to monitor. Moving to the Open Telemetry collector has become essential so that only 1 agent is required for both SIEM and application observability.

I don't think I've ever seen Splunk ES go fully offline or have any downtime greater than a few minutes on rare occasions.

It takes a long time for items to load if you are just generally searching through logs. It is best to use the data models which load faster but can be strange in terms of what is coming from which logs where. Yes, you can look it up, but this also requires familiarity with where things are and how to look them up.

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.

It's good when it's responsive, but I've had times where I had to wait quite a while for a response. But these are typically the exceptions rather than the rule. When you do get a response it is always well-informed and appropriate. I would say they've been trending better over time with this.

I experienced only on-line training, but the trainers were very professional and competent. Maybe it could be more useful if they also have an experience in projects because sometimes they didn't have a real project experience to communicate to the students. Anyway, it was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself, aven if I have more than 10 years of Splunk activity experience.

It was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself. The only problem was that, when I worked with the Splunk Professional Services, I found some difference between the training contents and the information from PS. In addition is required a long experience on Splunk Enterprise for the data ingestion part, in other words I'm able to work with ES because I'm worling on Splunk since 11 years, otherwise I'd some problem.

It's a fantatic product and it was very useful the presence of Splunk Professional Services for the Design Phase and the final Health Check.

Azure Monitor is not exactly what I mean, but I couldn't find Azure Application Insights. Anyway, for a large organization, Azure makes more sense than using Graylog because a lot of logging will already be inside Azure. And you don't want to have two "central" logging locations. But Azure is chaos and highly "not intuitive." So for small and mid-size organizations, Graylog is still the better option.

Before Splunk, we ran Elastic Security for our log aggregation and alerting platform. Unfortunately, the solution was not a good fit for many logs and mixed on-prem/cloud infrastructure, as our. For cost or small infrastructure, Elastic is a very good, strong, and credible choice. But if you need a performant SIEM, enjoy Splunk.

We have on prem splunk and it’s mostly east to setup, but we have issues keeping data separated between customer splunk deployments while at the same time only having to look at one SIEM to address events in every environment
