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

"What I like about this product, is that it is a fully-fledged solution."
"The most valuable feature is the logging capability."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"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 solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The initial setup was straightforward. I didn't have any problems."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"You can customize the dashboards as well as the reporting."
"EventTracker is exactly that; it's giving me all of the features and functions that we need to do our jobs, and at a price point that's incredibly attractive."
"Overall, we're really thrilled with them."
"When I looked last week, we probably averaged about 20 million log entries a day. So, we certainly can't individually manage that. Just looking at the reports, then trying to go back and find anything that was questionable, was a challenge. Therefore, the managed service has been invaluable to us in terms of being able to narrow the scope of what really needs to be looked at and bringing those things to our attention to be dealt with."
"The managed service is great value which saves you a full-time employee on your staff by being able to outsource it to EventTracker to review all the logs and cull through the data to make recommendations and identify threats, then how to remediate them."
"The biggest lesson I have learned is that the outsourcing of this service has a dramatic impact on the organization."
"The SIEMs and managed service are its most valuable features. We get a weekly report from them which provides a culmination of them combing through millions of events which are triggered across our network every day and minute. Their information security experts basically boil that down to a report which I get emailed once a week. It identifies potential threats and the remediation that I should take to be able to quell those threats."
"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."
"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

"The price of this solution is very high and it could be cheaper."
"GUI could be improved."
"AlienVault OSSIM is costly."
"Sometimes it takes very long for your issue to get resolved."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"We need more dashboards and we need more customization for dashboards."
"The user interface needs to be friendlier across the board."
"They can add more compliance templates."
"Netsurion's threat detection and response aren't quite mature. I would expect a little more."
"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'd like to see improvement in the ease of generating reports. It seems fairly cumbersome whenever you decide to start tracking new categories of events. It seems a little kludgy when trying to generate those reports."
"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."
"Using Netsurion has not meant we have consolidated cybersecurity technologies."
"The hosted on-premise hardware that we were using was having issues. The performance of it was horrendous, but we weren't using it."
"Where there is an opportunity for improvement is in the interface used for performing the searches. You have to understand Elasticsearch search too well for the security team to be able to take really full advantage of that part of the product. It's not as intuitive as I would like it to be for new staff coming in. The general query capability is a little bit challenging."
"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."
 

Pricing and Cost Advice

"The tool's licensing costs are yearly."
"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 solution is open source, so it's free to use."
"AlienVault OSSIM is an open-source solution."
"OSSIM is free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"We are using the community version, which can be used for free."
"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."
"Our pricing for Netsurion last year was US $52,000 per year."
"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."
"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."
"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."
"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."
"When we first got the EventTracker product, we were using SIEM Simplified. At the time they didn't call it that, but it was more of a service thing. So, there was a bit more hand-holding and getting stuff set up, along with failure reports, that they did during the first one to two years. Then, we decided that the the additional money to have someone do these daily reports wasn't terribly useful, so we discontinued that service."
"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."
