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

"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."
"The initial setup was straightforward. I didn't have any problems."
"I have deployed it widely because I find that it gives value for money."
"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."
"Network traffic analysis is highly efficient."
"The solution is free to use."
"If you want to secure your infrastructure and save a lot of time for your organization, you can use Huntress Managed SIEM."
"Huntress Managed SIEM is designed to make powerful threat detection, response, and compliance support accessible without the complexities and costs of traditional SIEMs."
"The single pane of glass management with the other security products we use from Huntress is incredibly valuable."
"Huntress Managed SIEM was able to detect zero-days and alert our team before they could be exploited."
"Huntress Managed SIEM has positively impacted my organization primarily by helping us help our customers achieve the compliance levels at which they are trying to achieve, and it also gives us additional information when we are reacting to security events that are presented from Huntress's SOC."
"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's response time is far superior to any other vendor we have tested in terms of MDR."
"Having real people reviewing the alerts compared to automated systems gives me confidence and peace of mind."
 

Cons

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"Lacking in depth of reporting."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"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."
"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."
"In my opinion, there is room for improvement in Huntress Managed SIEM, particularly in integration with third-party solutions."
"Huntress Managed SIEM could do better in terms of improved UI and also in terms of making it more simple for users."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is an open-source solution."
"OSSIM is 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."
"The solution is open source, so it's free to use."
"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 free."
