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

"We have a better detection rate for malware and other cyber-attacks, and it really helps when USM is integrated in the incident response plan."
"AlienVault is willing to offer flexible and competitive pricing."
"Customer Service: There is excellent customer service and we have never had a complaint."
"The most valuable feature of the solution is the ease of deployment that it provides to users. The integrations that the product has with third-party applications are useful."
"Being the only Security professional in an organisation of well over 1000 people AlienVault lets me keep a watchful eye whilst getting on with my day job."
"The most valuable feature in AT&T AlienVault USM is the reporting."
"The solution has all the features that we need, however they do not work correctly."
"AlienVault is the more appropriate solution, it's flexible, Linux based, and contains a large number of open source solutions."
"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 has a separate config file in addition to the core configuration."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"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."
"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."
"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."
"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."
 

Cons

"This solution could be easier to use."
"Upgrading the network cards (from 1GB to 10GB) was not “supported” on the appliance, so we had to purchase a second one as a sensor."
"Backup, restore, and upgrade - some menu options are a bit convoluted."
"The price of AT&T AlienVault USM could be reduced."
"I knocked off a point for the learning curve compared to some of the competition and another point for the lack of native user behavior analytics but for the money you really can't do any better."
"It needs to be easier to deploy switch monitoring."
"AlienVault cannot automatically respond to threats like other SIEM solutions, such as Sentinel and LogRhythm. Most of our clients are far away, so it's often challenging to handle alerts when they come up on our dashboard."
"I've experienced frequent slowness, and we had to downgrade to filter out many logs."
"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."
"There is room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
 

Pricing and Cost Advice

"Use an MSSP instead. It is much cheaper."
"It's saved security costs."
"The ROI is quite good."
"AlienVault is certainly not nearly as expensive as Splunk or QRadar. It's decently priced, but I don't have the exact figure."
"​The price point is good.​"
"They are a little more expensive than Microsoft."
"So far, it has been a good solution for a tight budget."
"It allows you to do a lot with a small price tag... The pricing is the best on the market."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
