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.

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 feature is the logging capability."
"You can customize the dashboards as well as the reporting."
"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 initial setup is straightforward."
"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 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."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
More AlienVault OSSIM pros
"The most valuable feature is the reporting."
"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."
"The most valuable feature of this solution is the visibility into both attempted and failed logins."
"The most valuable feature of SolarWinds Security Event Manager is the analysis and the knowledge about the incidence that we trace."
"The most valuable feature is the ease of use for the end user."
"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."
"The solution helps you monitor database instances, application instances, other customer application things, Linux servers, IBM servers, and Oracle servers."

Cons

"AlienVault OSSIM’s configuration and integration could be a little easier."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"GUI could be improved."
"The user interface could be improved."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"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 incidence reporting could be better."
"The solution needs more integration with cyber intelligence systems."
More AlienVault OSSIM cons
"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."
"It is a very technical program. They can simplify it so that it isn't so hard to deal with."
"I think the customization area in the tool can be considered as an area of concern where improvements are required."
"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."
"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."
"There are no multiple dashboards which would allow you to see information side-by-side."
"The only issue is the pricetag. SolarWinds is a costly solution."
More SolarWinds Security Event Manager cons
 

Pricing and Cost Advice

"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."
"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."
"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."
"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 free."
"AlienVault OSSIM is expensive compared to its competitors."
"The solution is open source, so it's free to use."
More AlienVault OSSIM pricing and cost advice
"Licenses can only be purchased in blocks of fifty at a time."
"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."
"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."
"Licensing is on devices, so if you have many, then this may be high."
"The price of SolarWinds Security Event Manager is reasonable."
"The pricing model would benefit from having package deals with other SolarWinds products."

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.
