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.

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."
"The product is easy to use."
"You can customize the dashboards as well as the reporting."
"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 paid version of the solution has reporting and better scalability options."
"The solution is free to use."
"I recommend it due to the experience of the people running it."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"Customer Service: There is excellent customer service and we have never had a complaint."
"IDS is a nice capability to have."
"The most useful feature is the customization for alarms, alerts, and reports."
"ATT AlienVault USM support is very good, they respond quickly to our needs."
"Pricing was a very important consideration and lower than the other SIEM solutions evaluated."
"We find AlienVault to have the best price to performance value."
"The most valuable feature is vulnerability management because it gives you insight into your environment to know what systems need to be updated or patched."
"The most valuable feature of the solution is the ease of deployment that it provides to users. The integrations that the product has with third-party applications are useful."
 

Cons

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"The user interface could be improved."
"The price of this solution is very high and it could be cheaper."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The user interface needs to be friendlier across the board."
"Yet, a lot of the releases break things that are used."
"I don't think the product's pricing is a good value because they try to raise the price 50 percent every year."
"It is a lot of work to get the software configured and set up properly."
"Pay attention to false-positive event automatic correlations."
"Reporting still needs a lot of work, especially on the vulnerability side."
"Reporting is convoluted and difficult at times, although they claim to have hundreds of pre-built reports, very few of them are actually useful for anything but what the USM is doing."
"I knocked off a point for the learning curve compared to some of the competition and another point for the lack of native user behavior analytics but for the money you really can't do any better."
"In the future, I would like to see all these features of the solution working properly."
 

Pricing and Cost Advice

"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."
"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."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"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."
"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."
"OSSIM is free."
"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."
"Use an MSSP instead. It is much cheaper."
"It's saved security costs."
"So far, I feel the product's pricing is a good value. The technology is decent. You get what you pay for. I think it's fair."
"QRadar, ArcSight and Splunk are some of the most expensive SIEM products out there in the market and not everyone has the budget to buy them. In such cases, AV USM is a very cost effective alternative."
"Pricing is very competitive with other products and you get much more functionality from AlienVault."
"It is affordable, and it also has many features that the premium products such as ArcSight and QRadar have. It is a very good platform for a SIEM solution. Everything is included in the price."
"The pricing is a good value. The key thing is that for the new product, the licensing of it, is subscription-based and it's based on data. Clients need to be really careful when thinking about that, because odds are they're going to need to put a lot more data into it than what they initially estimate, which is going to drive their subscription costs up."
"Its price is in the medium to upper range."
