Enables cost-effective security management for small businesses
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.

Great for PCI compliance but issues with stability and large amounts of data
I mainly use this solution to meet PCI compliance The automation of compliance reports and the correlation of the log have been major improvements.  The most valuable feature is the predefined reports for PCI compliance. The correlation suite needs to be improved. I also think they need to…

Quotes from Members

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

Pros

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"The initial setup was straightforward."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think AlienVault has the best price-performance ratio."
"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."
"The FIM features in the Change Tracker and the Log Tracker are the most valuable."
"If you want to deploy a SIEM and you want it to be simple, and not deal with much maintenance or help from the OEM, then I would say that NNT is the one."
"The Change Tracker tool is very good and will reduce your overall workload."
"This is a very easy-to-use interface with a quick ramp-up time."
"File integrity monitoring is a very important function."
"Customer Service: The service we've seen from NNT to date has been extraordinarily good."
"The automation of compliance reports and the correlation of the log have been major improvements."
"The most valuable feature is the predefined reports for PCI compliance."
 

Cons

"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The solution is not scalable."
"I don't like to work on OSSIM because it is unpredictable."
"The incidence reporting could be better."
"I would advise others to not implement it for any enterprise-level organization."
"Sometimes technical issues take very long to get resolved."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The correlation suite needs to be improved."
"It is able to identify the vulnerability, however, they need an option to auto-mitigate."
"Only one minor deployment issue came up and it was resolved quickly. No other areas of improvement come to mind yet."
"For the NNT Log Tracker and Change Tracker, they have to make their knowledge base available online because there is very little information available on the internet."
"There are some issues with the stability - the correlation engine has failed multiple times, and the reports sometimes take too long, so we have to involve the tech team to get them."
"I would like to see the integration of AI technology, so rather than manually monitoring the logs, the tool will understand it and take care of it."
"It is able to identify the vulnerability, however, they need an option to auto-mitigate."
 

Pricing and Cost Advice

"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 tool's licensing costs are yearly."
"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 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."
"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."
"AlienVault OSSIM is an open-source solution."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"NNT's pricing is moderate - I would rate their pricing two-and-a-half out of ten."
"We have selected a perpetual license along with support."
"Consider both their on-premises solution and their hosted solution. Both are reasonably priced."
