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.

Managed Services Engineer at Loop1 Systems

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.

More AlienVault OSSIM pros

Cons

"AlienVault OSSIM is costly."

"The solution needs more integration with cyber intelligence systems."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

"They can add more compliance templates."

"We need more dashboards and we need more customization for dashboards."

"AlienVault OSSIM’s configuration and integration could be a little easier."

"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."

More AlienVault OSSIM cons

"The company had to use a third party for the implementation of the solution."

"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."

"The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment."

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."

"The tool's licensing costs are yearly."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

"The solution is open source, so it's free to use."

"We are using the community version, which can be used for free."

"OSSIM is free."

"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."

More AlienVault OSSIM pricing and cost advice

"Licenses can only be purchased in blocks of fifty at a time."

"We do a yearly license renewal. For a year, the solution costs roughly $500,000 USD. There are no costs beyond this yearly fee."

"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."

"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."

"Licensing is on devices, so if you have many, then this may be high."

"The price of SolarWinds Security Event Manager is reasonable."

Also Known As

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.
