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

"AlienVault OSSIM's GUI is very user-friendly."

"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

"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."

"The paid version of the solution has reporting and better scalability options."

"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."

"The product is easy to use."

"The most valuable feature is the logging capability."

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."

More AlienVault OSSIM pros

"Asset discovery and vulnerability scanner are good features. The integration between this solution and OTX, which is an AlienVault platform for Open Threat Exchange, is also a valuable feature. It is also quick and easy to deploy, so you can quickly engage with a customer's environment."

"This solution can completely detect and prevent incidents on your network."

"The asset discovery and inventory capabilities in USM Anywhere is quite good."

"AlienVault provides a checklist answer when using SIEM."

"SIEM log collection is great, and all of the rules that support updates with maintenance."

"It has streamlined log aggregation and analysis to meet organizational and regulatory needs."

"Reports are customized, so you can present them to executives or engineers."

"The USM is a work horse, no matter what devices or the number of logs we throw at it, the system processes them in real time, correlates the events, and alerts on only events that need human review."

More USM Anywhere pros

Cons

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"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."

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."

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

"Sometimes technical issues take very long to get resolved."

"The documentation could be improved."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

More AlienVault OSSIM cons

"The one thing I continue to dislike about the USM is the limitation on reports."

"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."

"I've been told that AlienVault doesn't have a full version of NES running in there, but I'm not sure if that's accurate or if my engineer made it that way. I'm not sure he was completely honest either because we had NES in the environment before. Those tools could be improved because AlienVault is a SIEM, and it added all these other features."

"Maybe logs are the problem, as the database query is too slow. If you want to search something, you need time to find it."

"More complimentary training needs to be done for use with this tool. If you get into a bind, then it will cost you."

"The dashboard could be improved as well as the level of customization."

"It would be hard for any legitimate MSSP to use it."

"USM Anywhere relies a lot on the community putting the data in. Often, you'll right-click on the attack, but nothing will be found. That's a weakness of it."

More USM Anywhere cons

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."

"AlienVault OSSIM is 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."

"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."

"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."

"AlienVault OSSIM is an open-source solution."

"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."

More AlienVault OSSIM pricing and cost advice

"Negotiate the best package for your environment."

"Pricing is very competitive with other products and you get much more functionality from AlienVault."

"The price point is good."

"It's saved security costs."

"Do the one month trial and try to work out the kinks during it, as it has free support and service hours."

"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."

"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."

"They are a little more expensive than Microsoft."
