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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Pros

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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.""
"You can customize the dashboards as well as the reporting."
"With AlienVault you get everything in one box."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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 initial setup is straightforward."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"The documentation could be improved."
"AlienVault OSSIM is costly."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"They can add more compliance templates."
"The solution needs more integration with cyber intelligence systems."
"Sometimes technical issues take very long to get resolved."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"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."
"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."
"OSSIM is free."
"We are using the community version, which can be used for free."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"It’s a single license platform."
