AlienVault OSSIM

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

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.

Pros

AlienVault OSSIM

  • Most of the configuration comes out-of-the-box suited for most environments. Setting it up is really easy, with the wizard, you can have it working in less than 3 hours of deployment, without counting asset installation.
  • Out-of-the-box dashboards are really useful. You can modify or add new widgets to suit your needs, but you'll most likely agree with what already comes configured.
  • The tickets feature for handling alarms is really easy to use.

Graylog

  • Manages logs for a variety of devices
  • Easy to set up
  • A great open source solution

Cons

AlienVault OSSIM

  • The correlation directives that come out of the box are very few. I understand more correlation directives are a premium product, but one can hardly see the value of having very few. It makes new customers think they will not get better directives when they switch to the full USM or USM Anywhere.
  • Same with reports, the few reports it comes out of the box can be retrieved using other tools that are better prepared for the task. I understand that compliance reports aren't free, but at least I'd expect more security reports.
  • The OTX tab in dashboards sometimes takes too long to load, even if you have a fast internet and plenty of resources in the VM.

  • If you don't know your way around Linux setup would be tricky. Some step by step videos would be helpful.

Usability

AlienVault OSSIM

AlienVault OSSIM 8.0
Based on 1 answer
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.

Alternatives Considered

AlienVault OSSIM

AlienVault OSSIM has the upper ante in initial deployment price, being that it's open source. Also, with perhaps the exception of SolarWinds, it has a lower optimal requirements for onsite deployment, hence your OPEX won't be hit very hard by investing in new hardware to suit the appliance. The correlation engine is somewhat more robust that their counterparts in LogRhythm and SolarWinds, and the IDS (both NIDS and HIDS) are more reliable as well in terms of results. Finally, although Tenable SecurityCenter is more robust in dashboards, alerts and reports, it comes short in front of OSSIM in terms of real-time IDS and SIEM correlation.

Graylog

We previously used Syslog(-ng) and considered moving to the Logstash with Kibana as part of the standard ELK stack as we are consumers of ELK in other scenarios, but we determined that maintaining a distributed Graylog system was going to require less work overtime for our main objective than ELK. Splunk was also briefly considered, but holy wow do you pay significantly for licensing to perform the same functionality of Graylog.

Return on Investment

AlienVault OSSIM

  • The ROI of OSSIM itself is, obviously, immediate, being that it's a free, open-source product. However, you must take into account other inherent investments to cover up for the lack of official support, such as certified agents or consultants that take care of the management and maintenance of the product once in production.
  • On the other hand, the potential loss of information and interruption of operativity due to malware and other threats is really unmeasurable. The implicit savings in OSSIM as a SIEM (Security Information and Event Management) are really the major positive impact on your organization's revenue.
  • Finally, and from a reseller's point of view, reselling OSSIM has the big plus of being a professional services-only asset, given that the appliance itself is free of charge. The only thing to consider is the initial investment in team members with the required capacitation and knowledge to address such professional services to potential customers.

Graylog

  • We do not purchase support, so the only operational cost is that of the time it takes to maintain it.
  • All the components of Graylog that we use are free and open source, so there was no capital expense other than that of servers (repurposed from another recently-decommissioned project).
  • If there is a software crash that doesn't recover gracefully, it's usually something obscure that will take a while to diagnose and fix. Unless you build out a distributed and more resilient system with no single points of failure, that may have an impact on the organization or industry requirements for compliance.
