Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

Has supported client needs efficiently but requires deeper analysis features and faster support
The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment. More modification and enhancements are required on the dashboard side in order to make it closer to optimal performance. From observation and feedback from users, they need more functionality related to monitoring, and in-depth analyzing needs to be improved.

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 AlienVault OSSIM are case management, ease of configuration, and investigation."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"With AlienVault you get everything in one box."
"The solution is free to use."
"Technical support is excellent; they are very helpful and responsive."
"Better than other SIEM solutions because almost everything can be integrated."
"The scalability of SolarWinds Security Event Manager is good."
"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."
"It has in-depth monitoring capabilities and an easy way for setting up dashboards. I can expand in various areas, or I can reduce areas. It supports different types of breakdowns, filters, and rules. It is very simple for an out-of-the-box type of product. It doesn't take a lot of time to figure it out, which is unlike some of the solutions that I have looked at. It meets all the aspects."
"The most valuable feature is the reporting."
"The most valuable feature of this solution is the visibility into both attempted and failed logins."
"Some of the rules are most valuable because you can be notified about various things, such as spyware or things that are going on in the internal network."
"User-friendly configuration is key, and the configurations are simple, not complex."
"SolarWinds' stability is fine. I don't think we've had any software issues."
 

Cons

"The initial setup was not so easy, partly because the documentation was not up to date."
"The biggest thing I always complain about is that the user intake is a very old version."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"Lacking in depth of reporting."
"AlienVault OSSIM gives unwanted notifications."
"The user interface could be improved."
"Under the new system, it is not upgradable the way they say. When you try to do an upgrade, it doesn't really work unless you dump everything and start from scratch. You lose a lot of your nodes. Whenever you set your nodes up and everything else, they don't want to bring those nodes back in, so you have to really go back and restructure all your nodes. I went from version 6.5 to version 6.6 and then to version 6.7. I then went to version 2019, and now it is version 2020. It would be good if we can upgrade without having to delete everything and start from scratch. They can maybe build more KPIs and other things for the dashboard. Some of the other systems already have built-in KPIs. SolarWinds is starting to catch up, but it is not there yet. They can include some of the business or industry standards for tracking the time, that is, the meantime to detect (MTTD) and the meantime to resolve (MTTR). They can also find a way to build a KPI that measures the number of instances of port scans experienced in a week or a month."
"SolarWinds should improve its correlation capabilities. The correlation does not automatically detect and reduce the events fast enough. You have to manually do a correlation report, which means the tool is not scalable in many ways."
"Under the new system, it is not upgradable the way they say. When you try to do an upgrade, it doesn't really work unless you dump everything and start from scratch."
"We have automated threat detection in the Alliance Security, Antoinette. However, if these features could be further enhanced, it would simplify my work, potentially allowing me to allocate more time to address complex issues."
"One of the drawbacks of being so flexible is that it is also a fairly complicated software application to install, configure, and maintain."
"The reporting could be more robust. It can be a lot more granular and that will make it a lot more useful in comparison to how it is incorporated at the moment."
"I think the customization area in the tool can be considered as an area of concern where improvements are required."
"Not very scalable in my opinion. That's why I'm investigating new SIEM replacement."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"OSSIM is free."
"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 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."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault OSSIM is expensive compared to its competitors."
"We do a yearly license renewal. For a year, the solution costs roughly $500,000 USD. There are no costs beyond this yearly fee."
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."
"The price of SolarWinds Security Event Manager is reasonable."
"The tool is available at a good price for customers compared to other solutions in the market. I rate the product's price as an eight out of ten."
"Licensing is on devices, so if you have many, then this may be high."
"Licenses can only be purchased in blocks of fifty at a time."
"The pricing model would benefit from having package deals with other SolarWinds products."
