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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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.

Includes four services and four products, which can help organizations a lot
We found that sometimes integrations work, but testing them can take some time. Sometimes, configurations take much longer than expected. We have a configuration in place that needs to be synchronized with another server. However, the servers are four hours apart, so this can cause delays. In general, I believe that the time it takes to configure and test a service should be shorter. Sometimes, it can take a couple of hours to test a single configuration setting. Other times, it is only ten or fifteen minutes, which is normal. However, sometimes, even immediate actions can be triggered by configuration changes, and some settings can take up to eight hours to complete. I believe that this time can be improved. Microsoft is making a lot of improvements to its services in a short period of time. This is a good thing, as it means that the services are constantly being updated and improved. However, it can be challenging for customers to keep up with the changes. For example, a customer may read about an update, understand it, and share it with their colleagues and boss. However, it may take days or weeks to test the update and get the necessary approvals. This can be especially challenging for large customers with many users or machines. In some cases, Microsoft may change a service before the customer has had a chance to implement the previous update. This can be frustrating for customers, as it means that they have to constantly learn new things and adjust their workflows. On the one hand, it is important for Microsoft to keep updating and improving its services. This helps to ensure that the services are meeting the customers' needs and that they are staying ahead of the competition. Microsoft should also be mindful of the challenges that these changes can create for customers. One way to address this challenge is to provide customers with more time to implement changes. Microsoft could also provide more information about upcoming changes so that customers can plan ahead. Ultimately, Microsoft needs to strike a balance between keeping its services up-to-date and providing customers with a smooth transition to new features.

Quotes from Members

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

Pros

"The initial setup was straightforward. I didn't have any problems."
"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"The solution is free to use."
"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 gives a lot of flexibility in terms of configuration and customization as per the business requirements."
"I like Defender XDR's automation capabilities. XDR isn't automated by default, but you can automate it to respond. If an attack is performed anywhere within the organization, you can isolate that instance from the network. This is what I can figure out for it. When integrated with Sentinel, you can set up playbooks to automate all the alerts gathered on Sentinel from different Microsoft solutions. Sentinel has a wider range of capabilities than XDR."
"Microsoft Defender XDR is a complete package of different Defender solutions, including Defender for Endpoint, Defender for Office 365, Defender for Cloud, and Sentinel SIEM, among others."
"The comprehensiveness of Microsoft's threat detection is good."
"It has great stability."
"It's a great threat intelligence source for us, providing alerts for things it detects on the network and on the machines. We've used it often when there is a potential incident to see what was done on a computer. That works quite nicely because you can see everything that the user has done..."
"The ability to hunt that IM data set or the identity data set at the same time is valuable. As incident response professionals, we are very used to EDRs and having device process registry telemetry, but a lot of times, we do not have that identity data right there with us, so we have to go search for it in some other silo. Being able to cross-correlate via both datasets at the same time is something that we can only do in Def"
"The visibility into threats is also very impressive because Microsoft helps you predict things and provides analytics to help you really improve your security. And all of this technology works across the domain, so it is pretty helpful in terms of threat analytics."
 

Cons

"I don't like to work on OSSIM because it is unpredictable."
"The user interface could be improved."
"The documentation could be improved."
"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 solution needs more integration with cyber intelligence systems."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"They can add more compliance templates."
"AlienVault OSSIM gives unwanted notifications."
"The design of the user interface could use some work. Sometimes it's hard to find the exact information you need."
"The data recovery and backup could be improved."
"Because of the training model, Defender XDR's automatic response sometimes blocks legitimate users and activities. Also, the UI sometimes responds slowly."
"365 Defender has multiple subsets, including Defender for Cloud Apps. When integrating Defender for Cloud Apps with apps on third-party cloud platforms like AWS or GCP, there are limitations on our ability to control user activities. If Microsoft added more control over third-party products, that would be a game-changer and help us quite a lot."
"The message trace feature for investigating mail flow issues should add more detailed information to the summary report... if they could extend the summary report a little bit, make it more descriptive, ordinary administrators could understand what happened and that the emails failed at this or that point. That way they would know the location to go to try to correct it and to prevent it from occurring again."
"A simple dashboard without having to use MS Sentinel would be a welcome improvement."
"Just like in any solution, the price can always be cheaper."
"Stability could be improved by avoiding frequent changes to the interface."
 

Pricing and Cost Advice

"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."
"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 OSSIM is an open-source solution."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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 expensive compared to its competitors."
"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."
"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."
"I would like to have more security features in the lower licenses because not every customer is able to buy E5 licenses. The bundling isn't always easy for our customers to understand. Compared to other tools, it's a good price."
"It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size."
"Its licensing and pricing are handled by someone else. My role is limited to incidents or issues with the portal, but you get what you pay for. It is worth the cost."
"It is fairly priced because we get complete integrated services with the E5 license."
"The solution is affordable, and we haven't been hit with any hidden costs. The subscription model is straightforward, and it's easy to understand how much additional features cost. If we need to cancel a license or feature, we do that well in advance to avoid being charged for it, but overall, the pricing and licensing are simple and easy."
"Microsoft Defender XDR is included in our license."
"While Microsoft Defender XDR carries a higher cost, its ease of use compared to Defender may justify the investment."
"The most valuable licensing option is expensive, so pricing could be improved. Licensing options for this solution also need to be consolidated, because they frequently change."
