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.

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

"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

"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 threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."

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

"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."

"AlienVault OSSIM's GUI is very user-friendly."

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."

"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."

"SolarWinds is easy to configure, and it provides timely alerts."

"The most valuable feature is the ease of use for the end user."

"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."

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

"It's extremely easy to deploy."

"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."

More SolarWinds Security Event Manager pros

Cons

"Sometimes technical issues take very long to get resolved."

"The documentation could be improved."

"The user interface 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."

"The solution is not scalable."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

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

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

More AlienVault OSSIM cons

"It can be difficult for users who are inexperienced with the solution."

"I think the customization area in the tool can be considered as an area of concern where improvements are required."

"The only issue is the pricetag. SolarWinds is a costly solution."

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

"There are no multiple dashboards which would allow you to see information side-by-side."

"The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment."

"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 solution's technical support is okay, but we don't have an SLA, and sometimes the response times are very slow."

More SolarWinds Security Event Manager cons

Pricing and Cost Advice

"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."

"AlienVault OSSIM is an open-source solution."

"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 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."

"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."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

"Licenses can only be purchased in blocks of fifty at a time."

"The price of SolarWinds Security Event Manager is reasonable."

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

"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."

"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."

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.
