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

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

"Network traffic analysis is highly efficient."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"Asset discovery is good."

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

"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."

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

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

More AlienVault OSSIM pros

"The solution also provides basic log storage options for periods of 15, 30, and 90 days."

"Easy to use, scalable, stable, and very intuitive platform that provides protection against security threats."

"The Event Correlation and vulnerability scans have been the most useful. As a 24/7 SOC, we use the incoming alarms to give an overview of suspicious traffic going through the network. It's easy to look at the correlated events and see the broad picture of traffic for that customer. Vulnerability scans are good for providing patch and remediation guidelines to keep customer systems secure."

"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."

"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."

"AlienVault provides a checklist answer when using SIEM."

"As we have to service several servers, we can manage them in a economical way, which is beneficial to our team and business."

"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."

More USM Anywhere pros

Cons

"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."

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

"The solution is not scalable."

"They can add more compliance templates."

"The price of this solution is very high and it could be cheaper."

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

"AlienVault OSSIM is costly."

"GUI could be improved."

More AlienVault OSSIM cons

"I'd like to see a dashboard that's a little more descriptive."

"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."

"Windows log collection works with HIDS, but documentation is sparse and confusing."

"Search performance can be slow. The Raw Logs feature is painfully slow. And if we're talking about the newer, the Anywhere product, you can't even schedule reports on the thing. There are probably a dozen other features I'd really like to see there, but that would be one of the biggies."

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

"The other thing is the agent is OSSEC. They needed to create its own agent to help to find threats on the devices that it happens to be installed."

"The reporting is mediocre and is something that needs to be improved."

"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."

Pricing and Cost Advice

"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 free."

"The tool's licensing costs are yearly."

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

"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."

"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 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."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

"I rate the price of AT&T AlienVault USM a four out of five."

"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."

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

"Use the AlienVault team. They are helpful and the documentation that they provide is second to none."

"We pay around $12,000 a year including storage."

"They are a little more expensive than Microsoft."

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

"AlienVault is certainly not nearly as expensive as Splunk or QRadar. It's decently priced, but I don't have the exact figure."
