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.

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

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"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."
"The initial setup was straightforward. I didn't have any problems."
"You can customize the dashboards as well as the reporting."
"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 solution is very stable. Compared to Qradar and Splunk, it's very stable."
"The solution is free to use."
"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
More AlienVault OSSIM pros
"We did previously use a different solution, but SolarWinds is much better. It's easy to interact with SolarWinds. It's easy to operate, easy to configure and is generally easier compared to what we were working with before."
"SolarWinds is easy to configure, and it provides timely alerts."
"User-friendly configuration is key, and the configurations are simple, not complex."
"The solution helps me to go back in time and search for different events. For example, if you wanted to know who activated an account; you could go back in time and find out."
"SolarWinds is effective for server, network, and log monitoring. It's also good for IP address management. We also have a patch manager, but we're still working on getting that operational."
"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."
"The most valuable feature is the reporting."
"SolarWinds' stability is fine. I don't think we've had any software issues."
More SolarWinds Security Event Manager pros
 

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The documentation could be improved."
"Lacking in depth of reporting."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The solution needs more integration with cyber intelligence systems."
"It's so hard to configure and explore something new on it."
"The price of this solution is very high and it could be cheaper."
More AlienVault OSSIM cons
"The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment."
"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."
"The company had to use a third party for the implementation of the solution."
"It can be difficult for users who are inexperienced with the solution."
"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."
"One of the drawbacks of being so flexible is that it is also a fairly complicated software application to install, configure, and maintain."
"There is no correlation made between log entries, so no threat information is presented."
"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."
More SolarWinds Security Event Manager cons
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"AlienVault OSSIM is an open-source solution."
"AlienVault OSSIM is expensive compared to its competitors."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is free."
"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
"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 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."
"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 pricing model would benefit from having package deals with other SolarWinds products."

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.
