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

"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"What I like about this product, is that it is a fully-fledged solution."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"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."
"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 is free to use."
"The most valuable feature is the logging capability."
"Here we can get file integrity monitoring and a vulnerability assessment tool together with SIEM."
"AlientVault has helped us in improving our visualization and incident response during cybersecurity situations."
"As it includes a logger feature for gathering all logs from all devices (network devices, servers, hosts etc.) it has basically become the only software that we look at when we have a problem."
"We are able to get alerts perfectly with FIM and VA features."
"AlienVault provides us with a very easy to use, central spot to view log files, and take appropriate action."
"It helps to monitor the entire office in in a single point."
"IDS is a nice capability to have."
"AlienVault USM Anywhere provides us with SIEM, at a low price-point and with a great array of functionality."
 

Cons

"The user interface could be improved."
"I don't like to work on OSSIM because it is unpredictable."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"Lacking in depth of reporting."
"ArcSight works better than AlienVault right now."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"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."
"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."
"I've experienced frequent slowness, and we had to downgrade to filter out many logs."
"The reporting aspect could be improved. While there are a lot of different options available, there are still pieces which are missing."
"I've been using it just for my own personal upskilling in terms of how the product works. At the moment, it is pretty straightforward and simple, and it is working how it is supposed to. The feedback would come once it is deployed to customer sites. They'll be using it on a more frequent basis, and that's when the feedback would come in terms of the areas in which they're facing issues or are looking for simplicity."
"Although they use machine learning, the algorithms that they use are graph-based."
"In emergency cases, it is difficult to reach them."
"The solution is a bit complicated. It could be simplified quite a bit."
"The web UI can be clunky at times, with poor error handling."
 

Pricing and Cost Advice

"The tool's licensing costs are yearly."
"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."
"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."
"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."
"AlienVault OSSIM is free."
"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 free."
"Do the one month trial and try to work out the kinks during it, as it has free support and service hours."
"It has good pricing."
"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."
"We checked out several competitors. For what it can do and the cost, it was the best option!"
"The price of this solution is reasonable, which is one of the reasons why we selected it over other solutions."
"The licensing fees are dependent on usage."
"I don't think the product's pricing is a good value because they try to raise the price 50 percent every year... AlienVault needs to understand that not all customers are huge enterprises... Their sales team is way too aggressive. The price they advertise is not always the price you get."
"Negotiate the best package for your environment."
