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.

Quotes from Members

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

Pros

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

"The initial setup is straightforward."

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

"Asset discovery is good."

"You can customize the dashboards as well as the reporting."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"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 most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."

More AlienVault OSSIM pros

"AlienVault's reporting is good. I like that vulnerability assessment is part of the solution, and the UI is intuitive. Also, the overhead is low, which is to say we don't need a dedicated SOC team to manage and analyze things constantly. We're a small company that doesn't have those resources."

"The most valuable feature of this solution is security management for PCI DSS."

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

"The main menu: You can see everything there, what is happening on the servers, and in the logs, you can view more details of each event."

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

"It allows you to define what alerts you want to see, or not to see, as well as if you want them grouped, or ungrouped."

"It allows for a lot of out-of-the-box features: vuln scanning, HIDS/HIPS, and IDS."

"OTX is a great module that lets staff maintain and monitor updates regarding events in the infrastructure and takes decision to improve the security perimeter."

More USM Anywhere pros

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"The incidence reporting could be better."

"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."

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

"The documentation could be improved."

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

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

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

More AlienVault OSSIM cons

"AT&T AlienVault USM can improve searchable data. It should be available for more than 90 days. If you need more than 90 days of data, you have to put a request and they give you raw data, which is not easy to search. A good addition would be to allow users to search data older than 90 days."

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

"It would be nice to see some machine learning and monitoring of the configuration in network devices."

"Pay attention to false-positive event automatic correlations."

"There is room for improvement in Log parsing."

"In the future, I would like to see all these features of the solution working properly."

"The UI and overall processes need a little bit more love. This shows in the error banners that come up when you select certain things. There isn't a day that goes by that the UI doesn't error out and I can't view events for an alarm."

"For creating new rules, you have to be familiar with regular expressions. I feel there could be something built-in to make sure that process is easier."

More USM Anywhere cons

Pricing and Cost Advice

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

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"The tool's licensing costs are yearly."

"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."

"OSSIM is free."

"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."

"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

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

"Its price is much lower than McAfee ESM."

"AT&T AlienVault USM is an expensive solution and we pay for the license and the support separately. We paid for the license and support for three years."

"It's very reasonably priced. It was one of the lowest among the ones I looked at. Licensing is pretty flexible. They can do a two-year or a three-year, even a one-year, perhaps."

"The ROI is quite good."

"It's affordable for most customers."

"It is a product that is priced in a medium range, making it neither a cheap nor a costly product."

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