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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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 most valuable features of this solution are the data correlation and vulnerability assessment."
"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."
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"AlienVault OSSIM's GUI is very user-friendly."
"The solution is free to use."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The most valuable feature is the logging capability."
"I like Defender XDR's reports and alerts. They give you updates about the latest hotfixes and zero-day vulnerabilities, which gives me all the information I need to maintain my servers."
"Having a single pane of glass for all Microsoft security services makes everything much easier. A security analyst can go to a single portal and see everything in one view. The integration of everything into one portal is a huge benefit."
"A crucial aspect for our team is the inclusion of identity and access management tools from the vendor."
"Microsoft Defender XDR provides strong identity protection with comprehensive insights into risky user behavior and potential indicators of compromise."
"In Microsoft 365 vendor products, monitoring and connectivity across all Microsoft and third-party connectors enable viewing of all activity within those environments."
"Microsoft 365 Defender is simple to upgrade."
"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."
"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."
 

Cons

"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"The solution is not scalable."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"Lacking in depth of reporting."
"Sometimes technical issues take very long to get resolved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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."
"From a performance standpoint, improvements could be made."
"The web filtering solution needs to be improved because currently, it is very simple."
"There's still some more work to be done there. Additionally, the limited terminal live access an analyst has is very restricted."
"In the future, it would be beneficial for Microsoft to consider making the product more user-friendly or simplified for those who are interested in using it. Currently, it requires a high level of technical expertise, making it challenging for beginners or less experienced individuals."
"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."
"The Defender agent itself is more compatible with Windows 10 and Windows 11. Other than these two lines, there are so many compatibility issues. Security is not only about Microsoft. The core technical aspects of it are quite good, but it would be good if they can better support non-Microsoft solutions in terms of putting the agents directly into VMware and other virtualization solutions. There should be more emphasis on RHEL and other operating systems that we use, other than Windows, in the server category."
"Since all of our databases are updated and located in the cloud, I would like additional support for this."
"One of the biggest downsides of Microsoft products, in general, is that the menus are often difficult to find, as they tend to move from place to place between versions."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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."
"The tool's licensing costs are yearly."
"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."
"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 an open-source solution."
"The license cost for a year is approximately forty-four thousand, and this annual saving is a significant factor in our decision to switch."
"With the little idea I have about the costs, I can say that XDR tools tend to be a bit expensive. If you are using Microsoft Defender XDR, then you need to go for a subscription-based pricing model."
"It has consistently offered highly appealing academic pricing, with distinct rates for higher education and general educational purposes."
"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."
"The solution is too expensive."
"Microsoft 365 Defender offers competitive pricing."
"Microsoft purposely makes its license combinations complex and includes combinations like Microsoft 365 E3 and Microsoft 365 E5, Office 365 E3, Office 365 E5, and Office 365 E1, so you get confused. Microsoft tries to sell you a bundle of a lot of things together."
"Sometimes 365 Defender is expensive, but it can be moderate, depending on the organization's size and the license type. We're satisfied with the cost because it gives us a product that protects our entire environment with DLP. To compromise some cost, of course, we are to complete the most secure environment."
