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.

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

"You can customize the dashboards as well as the reporting."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"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," and the solution works well and allows me to have visibility into anomalous events."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"AlienVault OSSIM's GUI is very user-friendly."
"Network traffic analysis is highly efficient."
"Asset discovery is good."
"What I like most about Netsurion is the level of visibility and reporting."
"If I were to look at logs manually, there's no way I could do that. As an example, they are 48 million logs processed a day. There is no way I could look at all 48 million of those. So, it gives me a good structure to be able to look at the different incidents which are created and do different searches."
"Netsurion's security operations center is critical for us because they provide 24/7 monitoring, we've never had another company meet the same need in the past, and it's a valuable tool to have."
"Having this in place gives us the ability to see what's going on, on a daily basis, on all of our systems across the enterprise."
"If we need to do a search for user lockouts, we can go, search, and find locations where they have been locked out, then keep track of those events, historically."
"With the managed component, we get that personal attention and that consistent team to deal with, and to some extent, it's like they're part of our IT team."
"The most valuable feature is definitely real-time alerting, especially in situations where someone might attempt to exploit or hack into our network."
"There are a host of things that are most valuable. Obviously monitoring our environment and reporting out different events is important. They perform a suite of services. They monitor all of our servers, all of our key infrastructure, like our DNS, our switches, all that stuff. They aggregate and correlate that quarterly. They'll tell us if we're getting a lot of login failures and something is going on or if something's weird."
 

Cons

"ArcSight works better than AlienVault right now."
"I would advise others to not implement it for any enterprise-level organization."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"Lacking in depth of reporting."
"The user interface could be improved."
"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"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."
"Their SOC team can't understand our network because they haven't worked in the actual company. This does negatively affect security posture, e.g., if you don't have knowledge about the network, then you will miss things."
"Probably the biggest thing is just: Can I search for this and what's the best way to do it? If I'm looking for two events versus a singular event, I just throw it back at them. They're the experts on it."
"I would also like to have a dashboard that I can access anytime to review the real-time data from their website."
"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."
"With version 8, there are quite a few things. The query tool was one of the big ones, and the query speed was one of the big ones, but they've made some great strides between versions 8 and 9. There were also issues in version 8 around the ability to get the data back out. It's one thing to collect data, but it's a whole other thing to be able to present it or run it in a timely manner. The old tool, depending on how far back I was looking, might even time out and I would have to run it again."
"Netsurion's SOC can be a bit too aggressive at times."
"Where there is an opportunity for improvement is in the interface used for performing the searches."
"We get a report generated on a particular day of the week and we go through it, trying to mitigate problems and make sure we're seeing everything that's happening. It would be helpful if the SOC spent a little more time with us going through some of those reports."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"The solution is open source, so it's free to use."
"AlienVault OSSIM is expensive compared to its competitors."
"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 the community version, which can be used for free."
"The tool's licensing costs are yearly."
"OSSIM is free."
"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 pricing and licensing seem very reasonable. The managed service part of it feels like it gives me the equivalent of a full-time engineer for a lot less money. So, I feel it's a good value."
"You are paying for different levels, especially as far as the monitoring goes and how often you review it with the team. The other factor that figures in is how many nodes are on your network, such as clients, network equipment, servers, etc. There are some additional pieces on top of that, but it's laid out pretty simply, as far as how much you're going to pay for a node."
"We put together the package of what we needed. It was based pretty much on the number of agents that we were deploying. If we needed to manage logging from certain specific applications, like Active Directory and SQL Server, there has been no additional cost for that. We had agents deployed for those specific servers and the applications were included, then there was just an additional installation that they had to do for us."
"Our budget follows the calendar year. We just started a new budget year at the beginning of the month. We did budget for an increase in our threat management system selection. Therefore, we have the budget to implement and accommodate a threat management system change, including an increase for the quoted actions that we received to improve EventTracker. We are just waiting on our council to approve that budget, which might not be for a little while. Hopefully, when they do, we will be able to jump on doing something."
"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."
"EventTracker's subscription-based model is interesting as far as yearly license type stuff. It's nice because you know what it's going to be next year. We haven't really looked at any other solutions. The pricing at the time compared to the other solutions was a lot less. A couple of years ago, we actually looked at Splunk. The amount in Splunk's licensing model is based on 20 gigs a day, or something like that. Based on our number of logs and stuff that we were already generating, the costs would be substantially more for the amount of logs that we would be getting."
"Our pricing for Netsurion last year was US $52,000 per year."
"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."
