    An easy-to-scale open-source solution used for monitoring events on devices
    The area for improvement is a lot. When I started using it on our enterprise side, the issue we faced was, for example, if we were running at that time on AlienVault OSSIM v5.7.4. So, for some orders, we had to install some packages, and when we tried installing that package, some dependencies got upgraded to a new version. Now once that dependency got upgraded, the SQL, since you might be aware that OSSIM uses SQL database, now SQL and all the dependency in everything was not on the same version, and that caused the database to crash. The aforementioned area should be eased out by upgrading the patches and upgrading dependencies. This kind of thing is a disadvantage of OSSIM, and I would like them to work on this. But I have also raised service requests many times and gave it a push on the community section too. However, since it is a local source, they don't reply much over there. That is why I don't like to work on OSSIM because it is unpredictable. Once the storage goes above 50 percent, it starts behaving unpredictably. If you get stuck with a situation, then you need to drill a lockdown into that. Sometimes you get no luck. Then you have to just reimage the server with the new fresh OS of AlienVault. As for additional features, not much because if you move to the newer version, it is kind of getting more stable. But, to make my life easier, then I would say try to give more features. I know it's open source, so they also cannot provide me with more features. But still, if they can provide me with more features because right now it's becoming old. Right now, we are even moving from SIEM to Security Data Lake. So when we move to it, this will be literally outdated. No one can even expect anything out of it. The way security is moving, it will be outdated very soon. They have to also provide something new to keep this going for the future also.

    The alert fatigue and false positive rates have just plummeted, which is really exciting.
    empow has a few areas of improvement as with any other technology, such as continuing to drive innovation in the dashboard. While we've been extremely impressed with the dashboard's ease of use, flexibility, ability to drill down deeply, and focus very intently on an area of interest, there will always be opportunities to be more innovative and open it up to a wider audience than just the operations group, for example. With reporting, there is always a desire to have custom reporting for every client of empow. 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.

    Quotes from Members

    We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
     

    Pros

    "The most valuable feature is the logging capability."
    "The product is easy to use."
    "The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
    "The paid version of the solution has reporting and better scalability options."
    "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.""
    "It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
    "The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
    "The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
    More AlienVault OSSIM pros
    "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."
     

    Cons

    "The user interface could be improved."
    "The solution needs more integration with cyber intelligence systems."
    "AlienVault OSSIM should improve the deployment and make it unified like the USM."
    "The solution is not scalable."
    "AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
    "The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
    "It's so hard to configure and explore something new on it."
    "The documentation could be improved."
    More AlienVault OSSIM cons
    "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."
     

    Pricing and Cost Advice

    "AlienVault OSSIM is expensive compared to its competitors."
    "The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
    "AlienVault OSSIM is an open-source solution."
    "The tool's licensing costs are yearly."
    "The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
    "We are using the community version, which can be used for free."
    "The solution is open source, so it's free to use."
    "OSSIM is free."
    More AlienVault OSSIM pricing and cost advice
    "I don't have to put up with any longer with these hypercomplex licensing agreements. Every time I want to add some additional reporting as a compliance centric or regulatory specific, e.g., GDPR, PCI, or Sarbanes-Oxley, many providers would have an additional license for this, which felt a bit ridiculous to me. With the simplified licensing architecture, there were no hidden "gotchas" down the road with empow. Something I have experienced with other providers that I've worked with in the past."
    "With a higher degree of fidelity in the alarms, we were able to avoid adding additional resources to our teams. We take into account the cost of security resources in the market and the significantly higher fidelity from the alarms that are being generated. This drove down our costs with our MSSP. It drove down my cost for human capital internally. It drove down our need to have multiple resources supporting the underlying infrastructure and health and maintenance of empow as a platform from several resources down to one. Therefore, human capital costs were significantly reduced. Our operating expenses were significantly reduced. Our capital costs were significantly reduced while tripling our capacity and our run rate reduced. It was almost a "too good to be true" situation. Fortunately, for us, it worked out very nicely."
