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

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

"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 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.""

"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."

"Asset discovery is good."

"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."

"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."

"Network traffic analysis is highly efficient."

More AlienVault OSSIM pros

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

"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."

"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."

"The solution has all the features that we need, however they do not work correctly."

"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."

"The feature that I liked the most is that they have a vulnerability assessment package that comes along with the SIEM solution. So, whenever I find any threat or alert for any of the devices or servers, I could immediately initiate a vulnerability assessment scan on that machine. That is one of a kind. The price at which AlienVault operates is also valuable."

"AlienVault provides a checklist answer when using SIEM."

"Using the communication within the security device, it is easier to create plugins."

More USM Anywhere pros

Cons

"AlienVault OSSIM’s configuration and integration could be a little easier."

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

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

"GUI could be improved."

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

"The correlation engine needs to be improved."

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

"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."

More AlienVault OSSIM cons

"they seem to have bugs from time to time that go unfixed for a while and that is frustrating. I'm not saying the product needs to be bug-free, but they need to be responsive to bugs."

"Adding a parsing interface for the customers would make AT&T AlienVault USM better."

"The solution is a bit complicated. It could be simplified quite a bit."

"It should be able to communicate with other security solutions to stop threats."

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

"As this software is in the cloud, you do not have control on updates and general changes which are happening."

"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."

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

More USM Anywhere cons

Pricing and Cost Advice

"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 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 free."

"AlienVault OSSIM is an open-source solution."

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

"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

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

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

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

"They are a little more expensive than Microsoft."

"It is affordable, and it also has many features that the premium products such as ArcSight and QRadar have. It is a very good platform for a SIEM solution. Everything is included in the price."

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

"Its price is much lower than McAfee ESM."

"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."
