HarshBhardiya - PeerSpot reviewer
An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Rafal-Stas - PeerSpot reviewer
Helpful in areas like event management, log viewing, and information management
The product's initial setup phase on the cloud is pretty easy but on an on-premises version, I think it is of a moderate level. The solution is deployed on the cloud and on an on-premises model. The time required to deploy the solution depends on the customers' infrastructure, and it may range from a couple of weeks to a couple of months, as it depends on how many additional custom configurations are required. Around two to three engineers are usually involved in the tool's installation process.

Quotes from Members

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

Pros

"Better than other SIEM solutions because almost everything can be integrated."
"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.""
"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."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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."
"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."
"Network traffic analysis is highly efficient."
"The paid version of the solution has reporting and better scalability options."
More AlienVault OSSIM pros
"SolarWinds Security Event Manager has been generally working well."
"SolarWinds is effective for server, network, and log monitoring. It's also good for IP address management. We also have a patch manager, but we're still working on getting that operational."
"The most valuable feature is the reporting."
"The graphical user interface is very user-friendly. SolarWinds is a hybrid solution so you can use it across many platforms."
"This tool is simple to use."
"The solution helps you monitor database instances, application instances, other customer application things, Linux servers, IBM servers, and Oracle servers."
"It has in-depth monitoring capabilities and an easy way for setting up dashboards. I can expand in various areas, or I can reduce areas. It supports different types of breakdowns, filters, and rules. It is very simple for an out-of-the-box type of product. It doesn't take a lot of time to figure it out, which is unlike some of the solutions that I have looked at. It meets all the aspects."
"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."
More SolarWinds Security Event Manager pros
 

Cons

"The user interface needs to be friendlier across the board."
"I don't like to work on OSSIM because it is unpredictable."
"Sometimes technical issues take very long to get resolved."
"The user interface could be improved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"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 main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
More AlienVault OSSIM cons
"It won't tell you when your backups are failing, but it will give you hints when your database is running on full recovery."
"It is a very technical program. They can simplify it so that it isn't so hard to deal with."
"I would like to be able to dig deeper into the visibility of events or incidents to determine whether they are malicious, such as by doing behavior analysis."
"I don't think SolarWinds is scalable enough. It is somewhat limited when I need to deploy it across multiple environments in a distributed architecture."
"We have automated threat detection in the Alliance Security, Antoinette. However, if these features could be further enhanced, it would simplify my work, potentially allowing me to allocate more time to address complex issues."
"The company had to use a third party for the implementation of the solution."
"The only issue is the pricetag. SolarWinds is a costly solution."
"I would like to have a more customizable dashboard."
More SolarWinds Security Event Manager cons
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"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."
"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."
"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 licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
More AlienVault OSSIM pricing and cost advice
"Licenses can only be purchased in blocks of fifty at a time."
"Licensing is on devices, so if you have many, then this may be high."
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."
"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."
"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."

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.
