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.

Has supported client needs efficiently but requires deeper analysis features and faster support
The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment. More modification and enhancements are required on the dashboard side in order to make it closer to optimal performance. From observation and feedback from users, they need more functionality related to monitoring, and in-depth analyzing needs to be improved.

Quotes from Members

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

Pros

"AlienVault OSSIM's GUI is very user-friendly."
"With AlienVault you get everything in one box."
"The product is easy to use."
"Better than other SIEM solutions because almost everything can be integrated."
"The solution is free to use."
"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 open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
More AlienVault OSSIM pros
"We had to integrate with other teams, and the infrastructure deployment didn't take long. The integration involves learning with different teams, networking, and configuring various network devices and servers. Infrastructure deployment only took one or two days."
"The most valuable feature is the reporting."
"It's easy to build rules and actions based on the logs and event types we collect with the software."
"The product's most effective part in improving security stems from the fact that the solution is deployed for event management, log viewing, and information management."
"The solution helps you monitor database instances, application instances, other customer application things, Linux servers, IBM servers, and Oracle servers."
"SolarWinds Security Event Manager has been generally working well."
"The graphical user interface is very user-friendly. SolarWinds is a hybrid solution so you can use it across many platforms."
"The most valuable feature of SolarWinds Security Event Manager is the analysis and the knowledge about the incidence that we trace."
More SolarWinds Security Event Manager pros
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"AlienVault OSSIM gives unwanted notifications."
"They can add more compliance templates."
"I don't like to work on OSSIM because it is unpredictable."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"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."
More AlienVault OSSIM cons
"The only issue is the pricetag. SolarWinds is a costly solution."
"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."
"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."
"It can be difficult for users who are inexperienced with the solution."
"It is a very technical program. They can simplify it so that it isn't so hard to deal with."
"Training for this solution needs to be improved, as new employees are sometimes unfamiliar with the product."
"There are no multiple dashboards which would allow you to see information side-by-side."
"The solution's technical support is okay, but we don't have an SLA, and sometimes the response times are very slow."
More SolarWinds Security Event Manager cons
 

Pricing and Cost Advice

"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."
"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 expensive compared to its competitors."
"The tool's licensing costs are yearly."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault OSSIM is free."
More AlienVault OSSIM pricing and cost advice
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."
"Licensing is on devices, so if you have many, then this may be high."
"Licenses can only be purchased in blocks of fifty at a time."
"The pricing model would benefit from having package deals with other SolarWinds products."
"The tool is available at a good price for customers compared to other solutions in the market. I rate the product's price as an eight out of ten."
"The price of SolarWinds Security Event Manager is reasonable."
"We do a yearly license renewal. For a year, the solution costs roughly $500,000 USD. There are no costs beyond this yearly fee."

OSSIM
SolarWinds LEM, Solarwinds SIEM, TriGeo, Log and Event Manager
 

Overview

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.

AT&T

When TriGeo was acquired by SolarWinds, TriGeo SIM became known as SolarWinds Log & Event Manager. This product is a leading Security Information and Event Management (SIEM) product and log management solution, which provides log collection, analysis, and real-time correlation.
