Enables cost-effective security management for small businesses
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.

Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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," and the solution works well and allows me to have visibility into anomalous events."
"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."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"Better than other SIEM solutions because almost everything can be integrated."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"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."
"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."
"IBM QRadar is easy to use."
"This platform can collect and normalize data better than just about anything (if you want it to), but it will not be useful if it is not presented in a useful way."
"Overall, IBM QRadar is very good but no product is perfect."
"One of the most valuable features is its ability to integrate with other solutions. IBM has a lot of solutions and we have managed to make it work with IBM BigFix and MaaS360, and even Microsoft."
"Pulse, UEBA, and NBAD are the features that are the best, and they are the most useful from a SOC manager perspective."
"The most valuable feature is the searching capability and real-time operational use."
"IBM in Indonesia provides great support."
"Curator is the leader of teams in the market; it's a product with plenty of features and capabilities, and it's a very powerful solution."
 

Cons

"I would advise others to not implement it for any enterprise-level organization."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"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."
"I don't like to work on OSSIM because it is unpredictable."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"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."
"They can add more compliance templates."
"I would like for Yara to be supported by all components."
"Customer support needs some improvement as there have been a few cases where we were unable to reach them in time."
"The solution lacks vendor support."
"QRadar log integration of various applications can be a tough job at times."
"Some UI enhancements would be nice, such as exporting custom event properties and the ability to export rules."
"We had several serious issues with this product, which made it impossible to use for a customer."
"In terms of where it could be improved, this includes its forensics, incident response, and security operation center features."
"The quoting and the dashboard session could be improved. It should be more user-friendly."
 

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."
"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."
"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 tool's licensing costs are yearly."
"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 solution is open source, so it's free to use."
"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."
"There are different types of subscriptions available. We were on an annual subscription, but our customers typically choose the two years subscription option."
"There is a license required for this solution and it is an annual payment. I have found all solutions in the category to be expensive, including Splunk."
"QRadar UBA's price is a little more than street price and could be reduced."
"Most of the time, it is easier and cheaper to buy a new product or the QRadar box."
"The pricing is good."
"There are additional costs, such as the cost associated with the different hardware required for implementation and deployment. Along with the add-on apps, these are all additional costs, and they require licensing as well."
"On a scale of one to ten, I rate the price a one, where one is an extremely expensive product, and ten is a cheap product."
"There is a license required for this solution."
