AlienVault OSSIM and Microsoft Sentinel are both prominent security information and event management (SIEM) tools. Users prefer AlienVault OSSIM for its affordability and support, but Microsoft Sentinel offers more comprehensive features, making it a better long-term investment.
Features: AlienVault OSSIM users value its robust open-source capabilities, good integration with other tools, and affordability. Microsoft Sentinel users appreciate its advanced analytics, scalability, and cloud-native design. Sentinel's more comprehensive feature set is better suited for large enterprises.
Room for Improvement: AlienVault OSSIM users often note the need for a more intuitive user experience, enhanced log management, and better documentation. Microsoft Sentinel users mention the high learning curve, complexity, and sometimes cumbersome setup process. Despite its complexity, Sentinel's extensive capabilities make it a strong tool.
Ease of Deployment and Customer Service: AlienVault OSSIM users find the deployment process straightforward with reliable customer support. Microsoft Sentinel, while praised for its flexible deployment options, gets mixed reviews on support due to some users experiencing longer resolution times. However, Sentinel's cloud integration is noted as a significant advantage.
Pricing and ROI: AlienVault OSSIM is favored for its lower setup costs and faster ROI. Microsoft Sentinel, despite higher initial costs, is viewed as delivering better long-term ROI because of its advanced features and scalability, justifying the higher price point.
AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.
