HarshBhardiya - PeerSpot reviewer
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.
John-Berry - PeerSpot reviewer
The SOC center monitors, hunts, and notifies us of threats around the clock
I know they are working to resolve this issue, but Netsurion is currently unable to retrieve logs from S3 buckets. We use WP Engine for a lot of web hosting as well as AWS, and both of these platforms use S3 buckets. I would like Netsurion to be able to pull logs from Linux devices. We have some of that capability, and I believe they can do it. However, the way it works with Amazon is strange and glitchy. Therefore, working something out with Amazon would be great. Netsurion's SOC can be a bit too aggressive at times. We have asked them to adjust their playbook because I am tired of being notified about the same issue multiple times a day. I am aware of the issue, and it is not a cause for concern. Let's only take action on this issue if we see an actual problem.

Quotes from Members

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

Pros

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The product is easy to use."
"The most valuable feature is the logging capability."
"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 most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"The initial setup is straightforward."
"Better than other SIEM solutions because almost everything can be integrated."
"When it comes to threat detection and response, it does a very good job detecting and blocking on its own. And the SOC is a nice added value because they're doing analysis on things that aren't as obvious, on things that you can't just detect with a signature or behavior. Also, any SIEM will come with a lot of noise, so having them do a lot of the initial analysis to find out what's critical and what issues are false alarms is very good."
"They have what they call Elasticsearch which is very quick, although that's only available for the last seven days' worth of data. It used to be that, if I wanted to do a search from three days ago, it might take me 10 to 15 minutes because it had to actually unzip some archive files. So I really like that feature. It's almost instantaneous for anything within the last seven days."
"What I like most about Netsurion is the level of visibility and reporting."
"We don't have the eyeballs available to stare and watch for things, or even have the capability of building internal alert systems. So, the managed SOC has been huge for freeing up staff to work on other responsibilities. We are saving on at least one full-time employee."
"Netsurion's 24/7 monitoring has enhanced the overall security of the company. They have someone looking at the data 24/7 who will call us as needed. If their team spots a malicious process after hours, they notify the appropriate person by phone. We get a lot of actionable threat intelligence from Netsurion. For example, if a user clicks on a malicious link in a web page and starts an unusual process that isn't on the white-list, Netsurion's team can detect it and prevent it from executing. Afterward, they'll notify us by telephone, so we can respond and clean up whatever damage has occurred."
"They have a number of integrations with different products. Google Workspace is one of them, and Microsoft Azure is another one. They integrate with a number of other things, such as Duo for multi-factor authentication. They can pull the logs from Duo to see if users are coming from bad repeatable IPs or if there are malicious known IPs that may be popping up in the logs. They are able to see that, and they can identify that. Some of the other integrations they do are from inside your network. For firewalls, they can integrate with SonicWall, Cisco, Fortinet, etc. They have a pretty wide variety of things to integrate with and be able to pull the logins from those devices."
"I really appreciate the fact that the dashboard breaks everything down into a pretty easy view for me... It shows what changes are happening to privileged user accounts, access and identity, what's cropping up. It shows application activity and whether we've got system resources that aren't online and being found anymore. It's a pretty simple, easy, quick hit and there are the supporting logs behind it. If I need to drill down further, I can do that quickly. It's very effective."
"Netsurion was easy to deploy. I have worked with other systems that were a little less complex, but they weren't quite as easy to deploy."
 

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"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."
"Lacking in depth of reporting."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"GUI could be improved."
"The correlation engine needs to be improved."
"Sometimes technical issues take very long to get resolved."
"The biggest problem is that we have too many domain controllers. So, we have to keep all the clients and main system updated with the latest versions along with making sure all the firewalls are open."
"I would like to see the dashboard come up more quickly."
"Netsurion's SOC can be a bit too aggressive at times."
"Communication is always something that can be improved, but I feel that any time we've had a communication issue, it's quickly addressed when we bring those up at the monthly meetings. Usually, it's an individual that wasn't clear in the communication, it's not the process per se. You always have to be able to segregate if the process didn't work or an individual either didn't say the right thing or my people didn't understand what they were being told."
"The agents on the endpoints seem to fail quite a bit, requiring manual involvement from the local administrators. I would like to see their product be much more ad hoc and update automatically."
"I would like to see a faster response when we see things like 15,000 lockouts. I really wished that I had known that on Friday afternoon rather than waiting until I got the weekly report today. By the same token, they are looking at it from the point of view that this is a system or software malfunction. This is not a bad actor repeating the exact same password three times a second. Therefore, they can tell that this is not a bad thing. However, it's not a security event but it is an operational event for me. Knowing this sort of thing would help my team and me out more because then we would be able to clear out a lot of network traffic that we didn't know was going on. So, we would like quicker updates on non-high security events."
"There are some issues with searches taking a long period of time, but they assured me that they have implemented a new search function that's available in version 9, but which requires a solid-state hard drive... Depending on how many logs you have it could take a long time to return the results if you're looking back prior to the last 30 days."
"Netsurion's threat detection and response aren't quite mature. I would expect a little more."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"AlienVault 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."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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."
"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."
"The solution is fairly expensive, but in my experience, all of the SIEM applications that I've evaluated or looked at cost about the same."
"Licensing is very easy. Our CIO takes care of the billing, but in terms of price point, he hasn't complained, so it must be good."
"I don't know if the pricing is by the seat but we're paying about $20,000 to 25,000 a year. On top of that, we pay for the managed support services. That runs us about another $35,000 or $40,000 a year."
"Netsurion's pricing is extremely fair and flexible. The price of their SIEM product is reasonable, and you can pay for those services you want on top of that. It wasn't cheap, but it's competitive, and we intend to renew our contract."
"It is a bit expensive as compared to some of the other products that have come out in recent years. Expense-wise, the only downside is that it is not cheap."
"Our pricing for Netsurion last year was US $52,000 per year."
"We have seen time and cost savings. It prevents us from having to hire specialized people for this type of work. We would need to hire six staff members to accommodate the same service."
"In the security space, it's hard to quantify your return on investment. So, I don't. We spend about $40,000 a year and so. It's hard to say if the SIEM saved that much money."

Questions from the Community

What needs improvement with AlienVault OSSIM?
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 implement...
