AlienVault OSSIM (discontinued) vs. Graylog

The most obvious scenario in which OSSIM is well suited is in a single office/home office (SOHO) or small business, in which budget is reduced but asset discovery and vulnerability management are greatly needed and appreciated. OSSIM is lightweight and free, so the real challenge to face is to hire or assign an administrator to manage and operate it, instead of any investment on an expensive appliance. Also, as resellers, promoting usage of OSSIM to customers charging for professional services for installation, administration, and maintenance (remember that OSSIM doesn't have official support from AlienVault) is a great asset for the organization.

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.

• The graphs and visualizations are limited on the dashboard if there were more options it would be better for different kinds of data.

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.

From a product perspective, it's an 8.

I am still unhappy with the pricing model for the enterprise. Graylog competes against the likes of IBM and Splunk, but your still the new kid on the block. To price Graylog enterprise at 50k for 20GB ingest an unrealistic data. It would require multiple facets of Graylog to be stood up and only forward pruned logs to the paid version.

AlienVault OSSIM as the first experience with a SIEM is very fine, especially if your company is an SMB. Every SIEM shares some features in common with other products, features such as log retrieval and normalization. So if you stick with principles, you can learn other SIEM products as well. If your environment is not of a minimum size, LogRhythm might be overkill for your network, same with McAfee Enterprise Security Manager.

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.

• OSSIM and the installers didn't really help us optimize at installation. OSSIM went without optimization for almost two years before that fact was noticed. I think this decreased ROI.
• Finding and researching incidents is much faster with all data available. Sometimes too much data, though.

Incentivized

• Able to offer monitoring services to new and existing clients to increase revenue
• Staff have increased billing percentage
• Potential to expand security services
