BP
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 - PeerSpot reviewer
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.

"The most valuable feature is the logging capability."

More AlienVault OSSIM pros
"SolarWinds Security Event Manager has been generally working well."

"SolarWinds' stability is fine. I don't think we've had any software issues."
"The most valuable feature of SolarWinds Security Event Manager is the analysis and the knowledge about the incidence that we trace."

More SolarWinds Security Event Manager pros
 

Cons

"The documentation could be improved."
"It's so hard to configure and explore something new on it."
"The user interface could be improved."
"Lacking in depth of reporting."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The price of this solution is very high and it could be cheaper."
"The solution needs more integration with cyber intelligence systems."
"GUI could be improved."
More AlienVault OSSIM cons
"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 log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment."
"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."
"The only issue is the pricetag. SolarWinds is a costly solution."
"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."
"Training for this solution needs to be improved, as new employees are sometimes unfamiliar with the product."
"The company had to use a third party for the implementation of the solution."
"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

"We are using the community version, which can be used for free."
"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."
"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."
"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."
"AlienVault OSSIM is free."
"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."
More AlienVault OSSIM pricing and cost advice
"The price of SolarWinds Security Event Manager is reasonable."
"Licensing is on devices, so if you have many, then this may be high."
"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."
"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."
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."

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.
