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.

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

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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."
"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."
"The initial setup is straightforward."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"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 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."
More AlienVault OSSIM pros
"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."
"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."
"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 this solution is the visibility into both attempted and failed logins."
"It's extremely easy to deploy."
"It supports high availability, which is very helpful."
More SolarWinds Security Event Manager pros
 

Cons

"The solution is not scalable."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"The correlation engine needs to be improved."
"The incidence reporting could be better."
"I don't like to work on OSSIM because it is unpredictable."
More AlienVault OSSIM cons
"We'd like more customization capabilities."
"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."
"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."
"I would like to have a more customizable dashboard."
"One of the drawbacks of being so flexible is that it is also a fairly complicated software application to install, configure, and maintain."
"The product should improve the ease with which you can create event alerts. They are not as hard now but you need to have an easier way."
"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."

Pricing and Cost Advice

"AlienVault OSSIM is free."
"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 free."
"We are using the community version, which can be used for 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 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 an open-source solution."
More AlienVault OSSIM pricing and cost advice
"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 pricing model would benefit from having package deals with other SolarWinds products."
"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."
"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."

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.
