An open-source solution that provide good detection and more visibility

The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Quotes from Members

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

Pros

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

"The solution is free to use."

"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""

"Asset discovery is good."

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

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

More AlienVault OSSIM pros

"Its powerful correlation engine helps reduce time in manually correlating events."

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

"It provides a single pane of glass view, coupled with a whole security ecosystem. The ability to manage everything from a central point, including vulnerability assessments, asset management - including the services provided by the various hosts, NIDS, HIDS, etc. - provides a very efficient way of dealing with things."

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

"Vulnerability scanning helped out shortcomings of what was not patched in the past and what needed to be patched. This assisted with fine tuning the environment for compliance."

"Every activity on the firewall is recorded, and notifications are sent with this solution."

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

"We're using it more for reporting, that's all. We're using it to help our customers to pass any kind of audits that they receive."

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."

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

"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."

"AlienVault OSSIM gives unwanted notifications."

"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."

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

"The correlation engine needs to be improved."

"The documentation could be improved."

More AlienVault OSSIM cons

"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."

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

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

"There are scalability issues due to a 60 TB limit, which restricts its use for large customers like banks."

"The reporting and dashboards have room for improvement."

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

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

"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."

More USM Anywhere cons

Pricing and Cost Advice

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

"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."

"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 an open-source solution."

"We are using the community version, which can be used for 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 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."

More AlienVault OSSIM pricing and cost advice

"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."

"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 vulnerability management solution is worse than buying a Nessus Professional license."

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

"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."

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

"The licensing fees are dependent on usage."
