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.

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.
