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

"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."

"The initial setup was straightforward. I didn't have any problems."

"You can customize the dashboards as well as the reporting."

"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."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"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."

"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."

More AlienVault OSSIM pros

"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."

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

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

"The most valuable feature of this solution is the visibility into both attempted and failed logins."

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

"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 graphical user interface is very user-friendly. SolarWinds is a hybrid solution so you can use it across many platforms."

More SolarWinds Security Event Manager pros

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

"The correlation engine needs to be improved."

"They can add more compliance templates."

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

"The solution is not scalable."

"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."

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

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

More AlienVault OSSIM cons

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

"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."

"There is no correlation made between log entries, so no threat information is presented."

"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."

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

"Training for this solution needs to be improved, as new employees are sometimes unfamiliar with the product."

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

More SolarWinds Security Event Manager cons

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."

"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."

"The tool's licensing costs are yearly."

"AlienVault OSSIM is expensive compared to its competitors."

"OSSIM is 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."

"AlienVault OSSIM is free."

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

More AlienVault OSSIM pricing and cost advice

"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."

"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."

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

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.
