Featured Reviews

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.

Yashokanth Partkunan - PeerSpot reviewer
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

"The initial setup is straightforward."
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"The initial setup was straightforward. I didn't have any problems."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"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 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."
"You can customize the dashboards as well as the reporting."
More AlienVault OSSIM pros
"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."
"The most valuable feature is the ease of use for the end user."
"It supports high availability, which is very helpful."
"User-friendly configuration is key, and the configurations are simple, not complex."
"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."
"SolarWinds is easy to configure, and it provides timely alerts."
"SolarWinds Security Event Manager has been generally working well."
"The most valuable feature of this solution is the visibility into both attempted and failed logins."
More SolarWinds Security Event Manager pros
 

Cons

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"AlienVault OSSIM gives unwanted notifications."
"I don't like to work on OSSIM because it is unpredictable."
"GUI could be improved."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"The price of this solution is very high and it could be cheaper."
"The incidence reporting could be better."
"The correlation engine needs to be improved."
More AlienVault OSSIM cons
"The only issue is the pricetag. SolarWinds is a costly solution."
"We'd like more customization capabilities."
"The reporting could be more robust. It can be a lot more granular and that will make it a lot more useful in comparison to how it is incorporated at the moment."
"The solution's technical support is okay, but we don't have an SLA, and sometimes the response times are very slow."
"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."
"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."
"There are no multiple dashboards which would allow you to see information side-by-side."
"It can be difficult for users who are inexperienced with the solution."
More SolarWinds Security Event Manager cons
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"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."
"OSSIM is free."
"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."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
More AlienVault OSSIM pricing and cost advice
"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 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."
"Licensing is on devices, so if you have many, then this may be high."
"The price of SolarWinds Security Event Manager is reasonable."
"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."
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."

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.
