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.""

"Asset discovery is good."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"You can customize the dashboards as well as the reporting."

"With AlienVault you get everything in one box."

"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."

"The most valuable feature is the logging capability."

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."

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."

"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."

"Some of the rules are most valuable because you can be notified about various things, such as spyware or things that are going on in the internal network."

"The most valuable feature of SolarWinds Security Event Manager is the analysis and the knowledge about the incidence that we trace."

"This tool is simple to use."

"The most valuable feature is the reporting."

"User-friendly configuration is key, and the configurations are simple, not complex."

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

Cons

"AlienVault OSSIM gives unwanted notifications."

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

"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."

"They can add more compliance templates."

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

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

"GUI could be improved."

"The user interface needs to be friendlier across the board."

More AlienVault OSSIM cons

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

"SolarWinds should improve its correlation capabilities. The correlation does not automatically detect and reduce the events fast enough. You have to manually do a correlation report, which means the tool is not scalable in many ways."

"I would like to have a more customizable dashboard."

"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."

"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."

"It is a very technical program. They can simplify it so that it isn't so hard to deal with."

"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."

More SolarWinds Security Event Manager cons

Pricing and Cost Advice

"AlienVault OSSIM is free."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"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."

"AlienVault OSSIM is an open-source solution."

"The tool's licensing costs are yearly."

"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 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."

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

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."

"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."

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

"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.
