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

"Better than other SIEM solutions because almost everything can be integrated."

"Network traffic analysis is highly efficient."

"The initial setup is straightforward."

"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."

"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."

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

"The solution is free to use."

"The initial setup was straightforward. I didn't have any problems."

More AlienVault OSSIM pros

"Ease of deployment across various environments."

"It has allowed us to see what is happening on our servers."

"AlienVault provides a checklist answer when using SIEM."

"This solution can identify many threats inside the organization (compromised endpoints, configuration issues), as well as "outside" threats (botnets, network scanners, web-attacks, etc)."

"Allowed us to help our customers satisfy compliance needs around logging and monitoring."

"The pricing is amazing and really cheap."

"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."

"The asset management functionality (active and passive scans) is also really important. You can't protect what you do not know about, so having an inventory of all your devices and software is critical to a security management program."

More USM Anywhere pros

Cons

"The solution is not scalable."

"The solution needs more integration with cyber intelligence systems."

"It's so hard to configure and explore something new on it."

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"AlienVault OSSIM gives unwanted notifications."

"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."

"The user interface needs to be friendlier across the board."

More AlienVault OSSIM cons

"One area that has room for improvement is storage. AllienVault is a good place to put logs, but sometimes it's a tough place to go get logs... The logger can only hold so much data. If they improved that, that would help."

"The lack of mature functionality and expertise in any of those areas is a strong negative."

"AlienVault cannot automatically respond to threats like other SIEM solutions, such as Sentinel and LogRhythm. Most of our clients are far away, so it's often challenging to handle alerts when they come up on our dashboard."

"The reporting module could be a little easier to handle, as it requires quite some trial and error until you get the reports you want. Also, it would be great to have a graphical interface for the Network Intrusion Detection System's rule management."

"The reporting aspect could be improved. While there are a lot of different options available, there are still pieces which are missing."

"There is room for improvement in Log parsing."

"The only room for improvement I can mention is the initial installation procedures. I found that the online installation instructions for the product were missing important details, they lacked necessary steps."

"The solution is a bit complicated. It could be simplified quite a bit."

More USM Anywhere cons

Pricing and Cost Advice

"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."

"The tool's licensing costs are yearly."

"AlienVault OSSIM is an open-source solution."

"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."

"The solution is open source, so it's free to use."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

"It's affordable for most customers."

"The price for this solution is very good, but since the features do not work the price is expensive."

"AlienVault is flexible on their pricing for unlimited licenses."

"The vulnerability management solution is worse than buying a Nessus Professional license."

"We checked out several competitors. For what it can do and the cost, it was the best option!"

"It's saved security costs."

"It has good pricing."

"So far, it has been a good solution for a tight budget."
