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

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

"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."

"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."

"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."

"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."

"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 dashboard is the solution's most valuable aspect; it brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on," and the solution works well and allows me to have visibility into anomalous events."

"Technical support is excellent; they are very helpful and responsive."

"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."

More AlienVault OSSIM pros

"It's easy to build rules and actions based on the logs and event types we collect with the software."

"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."

"User-friendly configuration is key, and the configurations are simple, not complex."

"Technical support for this solution is good."

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

"SolarWinds Security Event Manager has been generally working well."

"We did previously use a different solution, but SolarWinds is much better; it's easy to interact with SolarWinds, easy to operate, easy to configure, and generally easier compared to what we were working with before."

"We were suffering from a lack of visibility into our logs, so we implemented SolarWinds LEM."

More SolarWinds Security Event Manager pros

Cons

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."

"The user interface needs to be friendlier across the board."

"I don't like to work on OSSIM because it is unpredictable."

"The price of this solution is very high and it could be cheaper."

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

"The initial setup was not so easy, partly because the documentation was not up to date."

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

More AlienVault OSSIM cons

"The flash-based interface can be improved because sometimes, the speed of monitoring is reduced."

"I would like to have a more customizable dashboard."

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

"Under the new system, it is not upgradable the way they say. When you try to do an upgrade, it doesn't really work unless you dump everything and start from scratch. You lose a lot of your nodes. Whenever you set your nodes up and everything else, they don't want to bring those nodes back in, so you have to really go back and restructure all your nodes. I went from version 6.5 to version 6.6 and then to version 6.7. I then went to version 2019, and now it is version 2020. It would be good if we can upgrade without having to delete everything and start from scratch. They can maybe build more KPIs and other things for the dashboard. Some of the other systems already have built-in KPIs. SolarWinds is starting to catch up, but it is not there yet. They can include some of the business or industry standards for tracking the time, that is, the meantime to detect (MTTD) and the meantime to resolve (MTTR). They can also find a way to build a KPI that measures the number of instances of port scans experienced in a week or a month."

"It won't tell you when your backups are failing, but it will give you hints when your database is running on full recovery."

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

"Under the new system, it is not upgradable the way they say. When you try to do an upgrade, it doesn't really work unless you dump everything and start from scratch."

Pricing and Cost Advice

"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."

"The solution is open source, so it's free to use."

"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."

"AlienVault OSSIM is expensive compared to its competitors."

"The tool's licensing costs are yearly."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"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."

More AlienVault OSSIM pricing and cost advice

"Licensing is on devices, so if you have many, then this may be high."

"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."

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

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

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.
