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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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 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 most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"Network traffic analysis is highly efficient."
"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 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 most valuable feature is the logging capability."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"You can customize the dashboards as well as the reporting."
"On the Windows side, Microsoft Defender XDR is definitely integrated into the operating system. Once we have it on the security dashboard, we can see a real-time storyline."
"Advanced hunting is good. I like that. We can drill down to lots of details."
"The most valuable feature depends on the scenario. For compliance, I like Microsoft Purview Information Protection and Data Loss Prevention. Sentinel is the most helpful feature for security. 365 Defender helps us prioritize threats across an enterprise. It's a crucial feature for the managed services team."
"Defender XDR offers richer insights into Defender XDR. It's a better overall experience."
"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."
"Microsoft Defender XDR has significantly improved our operational security."
"The EDR features are valuable. By getting the EDR features, we have more control over the device. We have information about events in real-time and more protection against zero-day threats and zero-day vulnerabilities. We can monitor every event or action that a device is going through. We can get an idea if it is something malicious or if we have to take any actions."
"Microsoft 365 Defender is a good solution and easy to use."
 

Cons

"Sometimes technical issues take very long to get resolved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"I don't like to work on OSSIM because it is unpredictable."
"The incidence reporting could be better."
"The correlation engine needs to be improved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"GUI could be improved."
"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."
"Customers say they want absolutely seamless integration between other Microsoft solutions and Defender XDR, including the ability to change device settings within the Defender portal. They need to contact the IT team responsible for the device management tools to change some settings. They would prefer that those changes be initiated directly from the Defender portal or applied from Intune without involving the IT operations team."
"Advanced attacks could use an improvement."
"I personally have not seen much evidence of how Defender can enhance the story of zero trust for enterprises."
"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."
"When discussing the secure score, which includes overviews and recommended actions, some of these recommended actions are not applicable to us, particularly those related to Microsoft Internet Explorer, which we do not use in any of our environments."
"The initial time spent setting up and configuring Defender XDR is a bit longer than the other solutions. If everything were on one portal, the platforms for managing policies or alerts would be simpler. We must automate and manage policies on Intune rather than the same portal."
"It would be beneficial to reduce the number of clicks required to navigate between blades, as the current navigation and breadcrumb system can be a bit confusing. Some inconsistencies exist between blades, which could be improved for a more seamless user and UI experience."
"Microsoft Defender XDR could be improved with a lower price."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is an open-source solution."
"The solution is open source, so it's free to use."
"The tool's licensing costs are yearly."
"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."
"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."
"OSSIM is free."
"Microsoft is not competitive with the pricing of the solution. The competitors are able to offer lower discounts. The price of the solution is higher."
"Defender XDR is included in the E5 license, but it's a bit too expensive."
"Purchasing Microsoft Defender XDR as part of a Microsoft 365 bundle can be cost-effective, but acquiring it as a standalone product may be more expensive."
"Defender plan 1 is tenant-wise, and Defender plan 2 is per-user, which makes it more expensive. To have certain features, you would need to purchase the E5 license. For all of the capabilities that the tool provides, the price, though it can be high, is fair."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper."
"The licensing fee for Microsoft 365 Defender is fair."
"Microsoft should provide lower-level licensing options. They should do it in such a way that even an individual could purchase a license, and it should be entirely flexible."
