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 believe Huntress Managed SIEM could be improved by increasing integrations with non-Microsoft solutions as this would broaden its appeal. A broader out-of-the-box solution for diverse environments including IoT, Mac OS, and Linux servers would be valuable. I would rate Huntress Managed SIEM an eight because a couple of things could be changed, such as having more integrations with non-Microsoft systems, improved customization on the dashboard, and enhanced reporting in the threat intelligence updates. Being unable to click on new niche variants of threats is another point I would mention, but overall an eight out of ten is a good score because I think it is a very well-priced solution for its capabilities and all the positives I have outlined. The eight rating is primarily influenced by those integration and customization points I mentioned, which are the main requests from customers.

Quotes from Members

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

Pros

"Technical support is excellent; they are very helpful and responsive."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"Better than other SIEM solutions because almost everything can be integrated."
"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 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.""
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"You can customize the dashboards as well as the reporting."
"During the year I have been using it, I have seen improvements such as no alert fatigue, which is beneficial, and obviously the automated threat detection."
"Huntress Managed SIEM is designed to make powerful threat detection, response, and compliance support accessible without the complexities and costs of traditional SIEMs."
"Huntress is a great company and incredibly helpful with deployment."
"The single pane of glass management with the other security products we use from Huntress is incredibly valuable."
"Huntress Managed SIEM's response time is far superior to any other vendor we have tested in terms of MDR."
"If you want to secure your infrastructure and save a lot of time for your organization, you can use Huntress Managed SIEM."
 

Cons

"The initial setup was not so easy, partly because the documentation was not up to date."
"Sometimes technical issues take very long to get resolved."
"They can add more compliance templates."
"The correlation engine needs to be improved."
"The correlation engine needs to be improved."
"The price of this solution is very high and it could be cheaper."
"The biggest thing I always complain about is that the user intake is a very old version."
"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."
"The scalability for SMEs and MSPs is noteworthy for a few hundred endpoints, but it struggles with scalability when dealing with high logs, multi-site, multi-tenant setups, and large volumes of endpoints, which poses a challenge."
"There should be better exclusions of log types and the ability to exclude specific types of logs that might be using a lot of data."
"I would appreciate more features in the stack. I would like Huntress Managed SIEM to integrate with EDRs like SentinelOne to combine that level of intelligence and information into their stack so that they can leverage whatever protections the client has and gather that intelligence to help with the MDR side."
"In my opinion, there is room for improvement in Huntress Managed SIEM, particularly in integration with third-party solutions."
"There should be better exclusions of log types and the ability to exclude specific types of logs that might be using a lot of data."
 

Pricing and Cost Advice

"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."
"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."
"We are using the community version, which can be used for free."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"OSSIM is free."
