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.

Enables automated threat intelligence sorting and enhances proactive threat hunting capabilities
You have to have at least a threat intelligence background or a SOC analyst background to use it, as that's the information you'll dig around with in there. If you don't have that kind of knowledge, it probably can be a little hard to use, but they do provide training. They offer training not only for how to use the platform but also some basic threat intelligence training to explain what these things are and what these terms mean. My company is a customer of Anomali. I would recommend it to other people. I would advise making sure you don't pick it without testing other products and have your use cases well thought out and documented before testing, so you know it will solve the problems you're trying to address. Keep an open mind with it and realize that whatever you can dream of, you can probably do with the platform. Overall, I would rate Anomali an eight out of ten.

Quotes from Members

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

Pros

"Asset discovery is good."
"Network traffic analysis is highly efficient."
"The initial setup was straightforward."
"What I like about this product, is that it is a fully-fledged solution."
"You can customize the dashboards as well as the reporting."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"We now have a very robust collection of threat intelligence based on the capabilities that Anomali provides."
"The feature I have found most valuable is credential monitoring. This feature is easy and quick."
"The most valuable aspect of Anomali is the threat modeling capability."
"I have found Cyber threat intelligence (CTI) very useful and concise. The solution is easy to use."
"I have found Cyber threat intelligence (CTI) very useful and concise. The solution is easy to use."
 

Cons

"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"I would advise others to not implement it for any enterprise-level organization."
"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."
"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."
"We need more dashboards and we need more customization for dashboards."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"A lot of tools can give you many features, such as CTI intelligence and a tax service reduction. However, many people are combining different tools together to have more capabilities. It is up to the consumer whether they want to have multiple tools or have one tool that serves the purpose. Anomali Enterprise could improve by combining all the other tools' features into one solution."
"Support in the past has been top-notch, but recent trends indicate that it has taken a back seat, as we often don't get answers for days."
"An area for improvement is the intelligence sharing within the Anomali community. The tagging system can be inconsistent, as any company can use any tags for their reporting."
"Anomali Enterprise could improve by combining all the other tools' features into one solution."
"Less code in integration would be nice when building blocks."
 

Pricing and Cost Advice

"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."
"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 tool's licensing costs are yearly."
"The solution is open source, so it's free to use."
"OSSIM is free."
"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."
"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."
"When comparing the price of Anomali Enterprise to other solutions it is in the medium to high range. However, I am satisfied with the price."
