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 …

If this is your first experience with a SIEM, this one can get you started. Take the time to learn the ins and outs of the product and you'll most likely be satisfied with it if your company is an SMB. If you need compliance reports, OSSIM is too small for you, you'll need to go with USM or USM Anywhere.

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.

Pros
AT&T Cybersecurity
  • Asset discovery. Once installed in a centric, network-accessible server, OSSIM can poll all your endpoints with common protocols (SSH, SNMP, WMI) to detect and discover site-wide assets to monitor. You only need to group them by your own criteria once added to the product.
  • SIEM Event Correlation. You can define quite complex correlation rules to detect possible suspicious or malicious actions or attempts in your network, in order to categorize them as real threats or as false positives, thus streamlining your risk assessment and management.
  • Ease of installation. The entire AlienVault OSSIM is self-contained in an ISO file, which can be burned into a DVD or just mounted in your server of choice (physical or virtual) for deployment. The installation process is automated and quote verbosed, with options for static IP, email messaging and others.
  • Ease of access. Being AlienVault OSSIM a self-contained appliance, it can be accessed via web by any device that supports a web browser, being that desktops, workstation, mobile devices, etc. The OSSIM dashboard and other features are automatically rearranged to adapt to the particular device being in use.

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).

Cons

  • Creating custom rules is a bit complicated

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

Usability
AT&T Cybersecurity
AlienVault OSSIM is far easy to use and manage - provided you know what you're doing. As any SIEM application, there is some background knowledge required in order to take advantage of the product's functionalities, such as the log correlation and analysis. Other than that, the application is quite usable and robust.

Everything is done through MSSP and installation pro services. Once those hours are burned up, then you're on your own without a lot of help. Typically the pro services hours aren't enough to get past 60 days and MSSP are hit and miss. We had a miss for installation helpers.

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

Originally my organization leveraged alien value due to the lower cost of entry and ability to manage it as a service provider. Unfortunately, after several years of working with this tool, it became unwieldy to use as it felt that almost every useful report had to be created by hand. As other tools have come out with the ability to do automated responses such as Stellar Data processor, we have begun to evaluate alternatives.

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.

Return on Investment
AT&T Cybersecurity
  • It satisfied a requirement of our audit team (internal and external).
  • Custom written alerts allow us to be proactive for some events.
  • Stable product means we don't spend a lot of time keeping it up and running.

  • 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.
