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.

Yashokanth Partkunan

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.

Quotes from Members

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

Pros

"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," and the solution works well and allows me to have visibility into anomalous events."

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."

"AlienVault OSSIM's GUI is very user-friendly."

"The paid version of the solution has reporting and better scalability options."

"The most valuable feature is the logging capability."

"The solution is free to use."

"Network traffic analysis is highly efficient."

More AlienVault OSSIM pros

"SolarWinds Security Event Manager has been generally working well."

"Technical support for this solution is good."

"It supports high availability, which is very helpful."

"It's extremely easy to deploy."

"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."

Cons

"The biggest thing I always complain about is that the user intake is a very old version."

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"The user interface could be improved."

"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."

"Lacking in depth of reporting."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

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

"They can add more compliance templates."

More AlienVault OSSIM cons

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

"There is no correlation made between log entries, so no threat information is presented."

"Training for this solution needs to be improved, as new employees are sometimes unfamiliar with the product."

"The product should improve the ease with which you can create event alerts. They are not as hard now but you need to have an easier way."

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

"We'd like more customization capabilities."

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

"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

"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 an open-source solution."

"AlienVault OSSIM is expensive compared to its competitors."

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

"AlienVault OSSIM is free."

"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."

"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."

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."

"The pricing model would benefit from having package deals with other SolarWinds products."

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

"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."

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

"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."

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.
