We performed a comparison between AlienVault OSSIM and i-SIEM based on real PeerSpot user reviews.
Find out what your peers are saying about Microsoft, Splunk, Wazuh and others in Security Information and Event Management (SIEM)."The most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."
"The features that stand out are the detection engine and its integration with multiple data sources."
"We can use Sentinel's playbook to block threats. It covers all of the environment, giving us great visibility."
"We didn't have anything similar. So, it really provides value from the incidents and automation point of view. The overview of the security fabric is most valuable."
"Sentinel has features that have helped improve our security poster. It helped us in going ahead and identifying the gaps via analysis and focusing on the key elements."
"What is most useful, is that it has a good connection to the Microsoft ecosystem, and I think that's the key part."
"The solution has features that helped improve the security posture of our clients. It provides the ability to correlate a large variety of log sources very cost-effectively, especially for Microsoft sources."
"Sentinel is a Microsoft product, so they provide very robust use cases and analytic groups, which are very beneficial for the security team. I also like the ability to integrate data sources into the software for on-premise and cloud-based solutions."
"The solution is free to use."
"With AlienVault you get everything in one box."
"The paid version of the solution has reporting and better scalability options."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"You can customize the dashboards as well as the reporting."
"As a result of the automation, we are able to manage SIEM with a small security team. I'm in a unique position where we have been growing the security organization quite rapidly over the last three and a half years. But, as a direct result of the empow transition and legacy collection of tools towards the empow platform, we've been able to keep that head count flat. We've been able to redirect a lot of the security team's time away from the wash, rinse, repeat activities of responding to alarms where we have a high degree of confidence that they will be false positives, adjusting the rules accordingly. This can be a bit frustrating for the analyst when they have to spend hours a day dealing with these types of probable false positives. So, it has helped not only us keep our headcount flat relative to the resources necessary to provide the assurances that our executives expect of us for monitoring, but allows our analyst team to spend the majority of their time doing what they love. They are spending their time meaningfully with a higher degree of confidence and enjoying getting into the incident response type activity."
"The solution could be more user-friendly; some query languages are required to operate it."
"If their UI was a bit more streamlined and easy to find when I need it, then that would be a great improvement."
"It would be good to have some connectors for third-party SIEM solutions. Many customers are struggling with the integration of Azure Sentinel with their on-premise SIEM. Microsoft is changing the log structure many times a year, which can corrupt a custom integration. It would be good to have some connectors developed by Microsoft or supply vendors, but they are not providing such functionality or tools."
"If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable."
"Microsoft Defender has a built-in threat expert option that enables you to contact an expert. That feature isn't available in Sentinel because it's a huge product that integrates all the technologies. I would like Microsoft to add the threat expert option so we can contact them. There are a few other features, like threat assessment that the PG team is working on. I expect them to release this feature in the next quarter."
"We've seen delays in getting the logs from third-party solutions and sometimes Microsoft products as well. It would be helpful if Microsoft created a list of the delays. That would make things more transparent for customers."
"We'd like also a better ticketing system, which is older."
"The following would be a challenge for any product in the market, but we have some in-house apps in our environment... our apps were built with different parameters and the APIs for them are not present in Sentinel. We are working with Microsoft to build those custom APIs that we require. That is currently in progress."
"I don't like to work on OSSIM because it is unpredictable."
"The documentation could be improved."
"We need more dashboards and we need more customization for dashboards."
"The price of this solution is very high and it could be cheaper."
"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."
"It's so hard to configure and explore something new on it."
"The user interface could be improved."
"AlienVault OSSIM gives unwanted notifications."
"Relative to keeping up with the sheer pace of cloud-native technologies, it should provide more options for clients to deploy their technologies in unique ways. This is an area that I recommend that they maintain focus."
