IBM Security QRadar and AlienVault OSSIM compete in the SIEM (Security Information and Event Management) category. Based on features, IBM Security QRadar seems to have the upper hand due to its robust analytics and scalability.
Features: IBM Security QRadar includes automatic log source identification, a robust correlation rule engine, and excellent compliance monitoring. AlienVault OSSIM is recognized for its open-source model, dashboard functionality, and ease of integration but lacks broad scalability and advanced analytics.
Room for Improvement: IBM Security QRadar can improve in incident management, API capabilities, and user experience simplification. AlienVault OSSIM users suggest enhancing integration with modern tools, better threat intelligence databases, and simplifying configuration and scalability for larger deployments.
Ease of Deployment and Customer Service: IBM Security QRadar offers flexible deployment options, although users report varying support experiences. AlienVault OSSIM is easy to deploy, especially in hybrid and on-premises environments, with customer service that is generally satisfactory despite occasional slow response times.
Pricing and ROI: IBM Security QRadar is often seen as expensive for small businesses due to its complex licensing and high costs but provides a strong ROI. AlienVault OSSIM, offered as an open-source solution, is more cost-effective, appealing to smaller businesses or those on tight budgets, although the paid version can be pricey compared to other solutions.

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.
IBM Security QRadar (recently acquired by Palo Alto Networks) is a security and analytics platform designed to defend against threats and scale security operations. This is done through integrated visibility, investigation, detection, and response. QRadar empowers security groups with actionable insights into high-priority threats by providing visibility into enterprise security data. Through centralized visibility, security teams and analysts can determine their security stance, which areas pose a potential threat, and which areas are critical. This will help streamline workflows by eliminating the need to pivot between tools.
IBM Security QRadar is built to address a wide range of security issues and can be easily scaled with minimal customization effort required. As data is ingested, QRadar administers automated, real-time security intelligence to swiftly and precisely discover and prioritize threats. The platform will issue alerts with actionable, rich context into developing threats. Security teams and analysts can then rapidly respond to minimize the attackers' strike. The solution will provide a complete view of activity in both cloud-based and on-premise environments as a large amount of data is ingested throughout the enterprise. Additionally, QRadar’s anomaly detection intelligence enables security teams to identify any user behavior changes that could be indicators of potential threats.
IBM QRadar Log Manager
To better help organizations protect themselves against potential security threats, attacks, and breaches, IBM QRadar Log Manager gathers, analyzes, preserves, and reports on security log events using QRadar Sense Analytics. All operating systems and applications, servers, devices, and applications are converted into searchable and actionable intelligent data. QRadar Log Manager then helps organizations meet compliance reporting and monitoring requirements, which can be further upgraded to QRadar SIEM for a more superior level of threat protection.
Some of QRadar Log Manager’s key features include:
Reviews from Real Users
IBM Security QRadar is a solution of choice among users because it provides a complete solution for security teams by integrating network analysis, log management, user behavior analytics, threat intelligence, and AI-powered investigations into a single solution. Users particularly like having a single window into their network and its ability to be used for larger enterprises.
Simon T., a cyber security services operations manager at an aerospace/defense firm, notes, "The most valuable thing about QRadar is that you have a single window into your network, SIEM, network flows, and risk management of your assets. If you use Splunk, for instance, then you still need a full packet capture solution, whereas the full packet capture solution is integrated within QRadar. Its application ecosystem makes it very powerful in terms of doing analysis."
A management executive at a security firm says, "What we like about QRadar and the models that IBM has, is it can go from a small-to-medium enterprise to a larger organization, and it gives you the same value."
