    An open-source solution that provide good detection and more visibility
    The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

    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 product is easy to use."
    "AlienVault OSSIM's GUI is very user-friendly."
    "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."
    "With AlienVault you get everything in one box."
    "Asset discovery is good."
    "Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
    "The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
    "The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
    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

    "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."
    "It's under heavy traffic. If you have heavy traffic, the system is slow."
    "They can add more compliance templates."
    "The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
    "There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
    "There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
    "The user interface needs to be friendlier across the board."
    "The solution needs more integration with cyber intelligence systems."
    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

    "The solution is open source, so it's free to use."
    "AlienVault OSSIM is free."
    "OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
    "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."
    "When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
    "AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
    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."
