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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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 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."
"I recommend it due to the experience of the people running it."
"The solution is free to use."
"The most valuable feature is the logging capability."
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"AlienVault OSSIM's GUI is very user-friendly."
"The 'Incidents and Alerts' tab is a valuable feature where we can find triggered alerts."
"It provides a single pane of glass within the 365 admin interface, streamlining our experience by consolidating information in one place and eliminating the need to navigate through multiple interfaces."
"I like that Defender is easy to use and the alerts are all in one central location."
"The most valuable features are spam filtering, attachment filtering, and antivirus protection."
"The Endpoint Manager is incredible; it has a very straightforward interface and is exceedingly easy to use. Pulling out and deploying different tags or resources is a simple task across various departments with different levels of security. The notifications are also simple and satisfying; it's great to see the bubble informing us which devices are compliant and which are waiting to update."
"We can automate routine tasks and write scripts to carry out difficult tasks, which makes things easier for us."
"The most valuable aspect is undoubtedly the exploration capability"
"In our company,we have faced multiple attacks over the last few months, but none of them have been successful, and I think Microsoft Defender XDR has played a major role in it."
 

Cons

"It's under heavy traffic. If you have heavy traffic, the system is slow."
"It's so hard to configure and explore something new on it."
"The solution is not scalable."
"We need more dashboards and we need more customization for dashboards."
"The incidence reporting could be better."
"Lacking in depth of reporting."
"GUI could be improved."
"The documentation could be improved."
"The onboarding and offboarding need improvement. I work with other vendors as well, and they have an option to add a device or remove a device from the portal, whereas with Microsoft 365 Defender, we need to do that manually. However, once you do that, everything can be controlled through the portal, but getting the device onboarded and offboarded is currently manual. If we have an option to simply remove a device from the portal or get a device added from the portal, it would be more convenient. The rest of the features are similar. This is the only area where I found it different from others. I would also like to be able to simply filter with a few of the queries that are already there."
"I personally have not seen much evidence of how Defender can enhance the story of zero trust for enterprises."
"Intrusion detection and prevention would be great to have with 365 Defender."
"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."
"Microsoft Defender XDR is not a full-fledged EDR or XDR."
"Advanced attacks could use an improvement."
"At times, there may be delays in the execution of certain actions and their effects."
"We should be able to use the product on devices like Apple, Linux, etc."
 

Pricing and Cost Advice

"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 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."
"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."
"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."
"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."
"It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size."
"The solutions price is fair for what they offer."
"While the standalone price of Defender XDR might seem high, its value becomes clear when considering the ease of implementation and smooth integration with our existing Microsoft infrastructure, especially when bundled with other Microsoft products."
"They have moved from a licensing model to pay-per-use... The question is: What happens if, for any reason, there's not enough budget to accept this model? That could be a great problem."
"The licensing fee for Microsoft 365 Defender is fair."
"Defender XDR is included in the E5 license, but it's a bit too expensive."
"All I can say again is the E5 gives you all the capabilities that it offers. It also gives Office 365 and one terabyte of storage. All in all, the E5 license model makes sense. There are some people who say it's quite costly, but rather than paying different vendors, it makes sense to go all in with Microsoft if you've got that licensing. From that perspective, it's cost-effective, but I can't comment much on that."
"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."
