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.

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 most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"With AlienVault you get everything in one box."
"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."
"The initial setup is straightforward."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
More AlienVault OSSIM pros
"This tool is simple to use."
"The most valuable feature is the reporting."
"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."
"The product's most effective part in improving security stems from the fact that the solution is deployed for event management, log viewing, and information management."
"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."
"The most valuable feature is the ease of use for the end user."
"The graphical user interface is very user-friendly. SolarWinds is a hybrid solution so you can use it across many platforms."
"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."
More SolarWinds Security Event Manager pros
 

Cons

"We need more dashboards and we need more customization for dashboards."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"The solution needs more integration with cyber intelligence systems."
"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."
"The correlation engine needs to be improved."
"GUI could be improved."
"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
"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."
"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."
"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."
"The only issue is the pricetag. SolarWinds is a costly solution."
"It can be difficult for users who are inexperienced with the solution."
"It won't tell you when your backups are failing, but it will give you hints when your database is running on full recovery."
"There is no correlation made between log entries, so no threat information is presented."
"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."
More SolarWinds Security Event Manager cons
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"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 OSSIM is expensive compared to its competitors."
"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
"The pricing model would benefit from having package deals with other SolarWinds products."
"The price of SolarWinds Security Event Manager is reasonable."
"Licensing is on devices, so if you have many, then this may be high."
"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."
"Licenses can only be purchased in blocks of fifty at a time."
"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.
