Graylog
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.

Well, it's definitely suited to log in monitor most of the normal security infrastructure and collect security telemetry. It also extends well to Microsoft's entire suite with regards to data collection for things like Office 365, Power BI, power apps, and the like. It is also pretty good at collecting information from homegrown applications, especially if you're building in Azure.

Pros
Graylog
  • 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).

  • Sentinel is by far the most efficient tool in supporting the highest number of solutions and products when it comes to data connection (or ingestion) and that too in the least complex manner possible. Most of the data connectors in Sentinel are very easy to configure and deploy.
  • Incident Management is undoubtedly one of the main USPs of Sentinel. With an easy-to-use UI, variety of utilities (adding tasks, manual triggering of playbooks, activity logs etc.) and provision of having an investigation map from the incident details page, Sentinel clearly stands out in this area.
  • I personally love the feature of integrating 'Threat Intelligence' to Sentinel from a free and one of the most reliable sources, Microsoft itself. This not only saves time for an analyst in checking the reputation of an entity but also allows to take actions on the suspicious entities at earliest.

Cons
Graylog
  • Support for more log sources
  • Event alerts/emails - Some cases where unable to separate data from multiple clients, and no easy fix
  • API - Limits results to 10,000 and can cause server to lockup on queries that exceed the limit

  • It takes some time to learn how to use and install it properly, and it does not connect effectively with external PaaS systems such as Salesforce CRM, Salesforce Commerce Cloud, and so on.
  • Microsoft can simplify the display of the logs to make them easier to study, and the user interface occasionally delays, which can also be enhanced.

The Microsoft Azure Sentinel solution is very good and even better if you use Azure. It's easy to implement and learn how to use the tool with an intuitive and simple interface. New updates are happening to always bring new news and improve the experience and usability. The solution brings reliability as it is from a very reliable manufacturer.

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.

Alternatives Considered
Graylog
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.

The key advantage of using Sentinel lies in Microsoft already being a renowned name in cloud services. Hence, the Collection of data at the cloud scale across all users, devices, applications, and infrastructure, both on-premises and especially in the MS Cloud, is super easy. Additionally, leveraging Threat Intel from Microsoft itself gives a sense of security, given their years of experience in the collection of intel. The AI and Machine learning features provided by MS is one of the finest.

Return on Investment
Graylog
  • 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.

  • Less overhead on integration of cloud-native logging
  • The KQL language is very helpful since it can be used for security and operational monitoring but as well for workbooks and dashboarding
  • A large community developing solutions is very helpful for a quick adoption
