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

"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 most valuable feature is the logging capability."

"With AlienVault you get everything in one box."

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

"I recommend it due to the experience of the people running it."

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

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

"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."

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."

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

"The solution helps you monitor database instances, application instances, other customer application things, Linux servers, IBM servers, and Oracle servers."

"It supports high availability, which is very helpful."

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

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

"Some of the rules are most valuable because you can be notified about various things, such as spyware or things that are going on in the internal network."

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

More SolarWinds Security Event Manager pros

Cons

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"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."

"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."

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

"AlienVault OSSIM is costly."

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

"They can add more compliance templates."

"It's so hard to configure and explore something new on it."

More AlienVault OSSIM cons

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

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

"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."

"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."

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

"I don't think SolarWinds is scalable enough. It is somewhat limited when I need to deploy it across multiple environments in a distributed architecture."

"We'd like more customization capabilities."

Pricing and Cost Advice

"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."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

"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 tool's licensing costs are yearly."

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

More AlienVault OSSIM pricing and cost advice

"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."

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

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.
