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

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

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

"The product is majorly used for threat detection of the agents on servers and endpoints."

"With AlienVault you get everything in one box."

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

"What I like about this product, is that it is a fully-fledged solution."

"The solution is free to use."

More AlienVault OSSIM pros

"Students becoming acclimated to the product can go out into the field and have first-hand knowledge on how to use a USM or SIEM product."

"Being able to identify security issues as they occur at near real time and then respond to them as soon as they occur is priceless."

"The low cost of entry SIEM functionality has increased due to network views and network traffic."

"It has powerful threat detection, incident response, and compliance management."

"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."

"This brought them all under one roof and allowed one person to do what 10 could not in a few hours a day."

"I'm glad we purchased it, wished we would have gone with outside monitoring instead of inhouse and there is a lot to learn; great product though."

"Any unusual behaviour, we can monitor. We have alerts set up to be sent when we receive signs of any unusual behaviour."

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."

"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."

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

"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."

"The solution is not scalable."

"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 biggest thing I always complain about is that the user intake is a very old version."

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

More AlienVault OSSIM cons

"Its reporting tools need improvements. It would be good if they can provide integration with other ticketing systems. Currently, we only have integration with Slack and Jira. It is also a bit slow, and its replication engine can be improved."

"We would love to be able to create custom rules based on a series of events, to create rule-sets where, for example, failed logins to the VPN Server are logged and then when a successful attempt follows soon after, it triggers an alarm for a Brute Force."

"The GUI needs to improve because it's not user-friendly."

"I don't think the product's pricing is a good value because they try to raise the price 50 percent every year."

"The solution already has quite good tools, however, they need better integration tools for linking with Office 365, Google Suite, and so on."

"The vulnerability reporting needs to have options to be able to sort or customize the output."

"They should improve the reporting capabilities. Different functions to customize reports should be added."

"Plugins could be better utilized, as some of them do not recognize all logs."

More USM Anywhere cons

Pricing and Cost Advice

"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 OSSIM is free."

"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 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 an open-source solution."

"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."

"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."

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

More AlienVault OSSIM pricing and cost advice

"Use an MSSP instead. It is much cheaper."

"They are a little more expensive than Microsoft."

"The price of this solution is reasonable, which is one of the reasons why we selected it over other solutions."

"I don't know exactly, but I know it is based on the number of logs and the retention duration, such as 30 days or something like that. So, the smallest package is about 500 a month for 30 days of logs. There is a virtual machine. You need resources for it. It is a log collecting VM. They provide the software, and you just have to load a virtual machine. So, you're going to incur some CPU RAM and storage for wherever this log collecting appliance is running, which typically is in our cloud and on our platform for the customer."

"The price point is good."

"QRadar, ArcSight and Splunk are some of the most expensive SIEM products out there in the market and not everyone has the budget to buy them. In such cases, AV USM is a very cost effective alternative."

"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."

"Its price is in the medium to upper range."
