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.

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

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."

"The most valuable feature is the logging capability."

"The product is easy to use."

"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."

"With AlienVault you get everything in one box."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

"The product is majorly used for threat detection of the agents on servers and endpoints."

More AlienVault OSSIM pros

"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."

"I like EventTracker's dashboard. I see it every time I log in because it's the first thing you get to. We have our own widgets that we use. For the sake of transparency, there are a few widgets that we look at there and then we move out from there... Among the particularly helpful widgets, the not-reporting widget is a big one. The number-of-logs-processed is also a good one."

"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."

"Expediting incident response is really great."

"We have also integrated our endpoint security into the Netsurion SIEM. That's important because we have all the events in one place; we don't have to manage them in multiple places. In addition, the embedded MITRE ATT&CK Framework was paramount in our decision to choose Managed Threat Protection because the MITRE Framework is the industry standard for threats."

"The most valuable feature is that we get the events: the alerts about disk space and the security reports that we get once a day, including user lockouts and the like."

"Their SOC team manages vulnerability management and IOC reviews. They stop bad processes when they happen. The best thing is their weekly reviews of what has been going on in the infrastructure as well as the things that they see and what we should look out for."

"The real-time alerting for things such as people getting dropped into a VPN group or the domain admin group — things like that which really shouldn't happen without proper change management, but we all know the reality, they do from time to time — gives me real-time visibility into what's going on."

More Netsurion pros

Cons

"The solution needs more integration with cyber intelligence systems."

"The solution is not scalable."

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

"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."

"I don't like to work on OSSIM because it is unpredictable."

"The documentation could be improved."

"The incidence reporting could be better."

"AlienVault OSSIM is costly."

More AlienVault OSSIM cons

"The deployment of the agents could be a bit easier. We always seem to have a bit of a challenge with that. A lot of times the agents either don't deploy or they quit responding, then we have to go and redeploy them."

"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."

"There's always room to improve because there would be no competition if they had a perfect solution. The GUI to perform searches within the product may not be intuitive to a new user."

"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."

"It would be great if they had a client for phones by which they could push a notification to us, as opposed to via email."

"The solution's dashboard is okay. The one thing that we ran into are issues when we upgraded to the newer version. It uses Elasticsearch for the different dashboard entries. So, we were running on spinning disks, and Elasticsearch didn't work that well. A number of the different dashboards, like my dashboard or different things like that, pull from Elasticsearch. Since Elasticsearch really wasn't working, we were having some issues with that, but we just migrated."

"The system requirements are very, very high. So I need a pretty powerful server to run. If they could lighten that load so that the on-premise part of their product didn't impact my systems as much that would be ideal."

"The MITRE ATT&CK framework could be faster when identifying and understanding sophisticated threats. Whenever something happens, we usually get notified a couple hours later."

More Netsurion cons

Pricing and Cost Advice

"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"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."

"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."

"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."

"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."

"The upfront costs have increased, and we have been locked into this contract. The cost of changing over from it is way too high."

"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."

"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."
