Has ensured compliance by centralizing log data and supporting secure connections
We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"You will wonder how you lived without it."
"The main menu: You can see everything there, what is happening on the servers, and in the logs, you can view more details of each event."
"AlienVault is the more appropriate solution, it's flexible, Linux based, and contains a large number of open source solutions."
"We’ve had 100% uptime since installation."
"Alien Vault had the best set up for MSPs — the way they are set up for billing and the way they set up their USM account."
"Vulnerability scanning helped out shortcomings of what was not patched in the past and what needed to be patched. This assisted with fine tuning the environment for compliance."
"Here we can get file integrity monitoring and a vulnerability assessment tool together with SIEM."
"Technical support is extremely reliable."
"Syslog-ng has a separate config file in addition to the core configuration."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
 

Cons

"This solution could be easier to use. It is hard for some people to understand, and they need to get training and certification just to understand what it's showing them."
"I had a renegade plugin that was installed by the company who helped me with the initial setup. The plugin was missing a command to rotate logs and would fill my hard drives capacity to full quickly."
"We have encountered stability issues; we have a high volume of logs passing through our SIEM and the default configuration couldn't handle all the data."
"The log query capability is pretty restrictive and I find myself searching through raw logs via command line more often than the GUI."
"Support can be slow at times, but the quality is high. Posted knowledge base articles could use improvement."
"AT&T AlienVault USM can improve searchable data. It should be available for more than 90 days. If you need more than 90 days of data, you have to put a request and they give you raw data, which is not easy to search. A good addition would be to allow users to search data older than 90 days."
"We would love to be able to create custom rules based on a series of events, to create rule-sets where, for example, failed logins to the VPN Server are logged and then when a successful attempt follows soon after, it triggers an alarm for a Brute Force."
"The reporting could do with some improvements for example the vulnerability report only tells you what vulnerabilities are open and lists them but there is no indication of how old they are at a glance and what vulnerabilities have been closed since the previous scans."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
"The filtering has room for improvement."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
 

Pricing and Cost Advice

"QRadar, ArcSight and Splunk are some of the most expensive SIEM products out there in the market and not everyone has the budget to buy them. In such cases, AV USM is a very cost effective alternative."
"They charge a license based on the storage. ATT AlienVault USM is a less expensive solution than IBM QRadar."
"AlienVault is flexible on their pricing for unlimited licenses."
"The price for this solution is very good, but since the features do not work the price is expensive."
"It's saved security costs."
"Negotiate the best package for your environment."
"They are a little more expensive than Microsoft."
"​The price point is good.​"
"Syslog-ng is a free open-source solution."
"Syslog-ng is open-source."
