AlienVault USM

Since AlienVault is a versatile tool, having versions for various cloud providers as well as virtualization frameworks, it adheres to the most diverse scenarios. Another strong point to be highlighted is how the company is constantly improving the product. AlienVault is famous for the effort the company puts behind the tool, and it is being improved constantly by adding new resources.

Great for basic, up/down component monitoring. Also good for canary checks, file directory monitoring, etc. It's a good Boolean monitoring tool, but once it fires off an alert, obtaining more data is problematic. It's nice, but it can be noisy if not implemented in an enterprise-wide, scalable, and manageable way.

Pros

  • Very in depth on scanning for inventory! This allows one to get the "50,000 feet" view of the organizations IT assets, and can narrow down on a specific inventory item with just a few clicks.
  • Conducts detailed vulnerability scans. While it doesn't mitigate the vulnerabilities, it gives us instructions on how to mitigate them..what steps we need to take.
  • The reporting function is phenomenal. It aggregates logs from other hardware and software, and can present a in-depth report based on that data.

  • Connectivity checks in nagios are simple and impactful. Having a ping check on every host should be step one in any Nagios deployment.
  • The plugin network for Nagios is huge, and very extensible. Chances are someone has already wrote and shared a plugin that does exactly what you need. But if not, you can write your own.
  • With features like remote plugin executor (NRPE) you can do remote checks (pull style) instead of push. Having the option to do both is great.

Cons

  • Performance is not great at more than 300 EPS; bottleneck appears to be the MySQL disk I/O
  • Dashboards are decent to customize, but are lacking
  • UI and services aren't always stable or predictable; when adding a new plugin it sometimes takes things like a reconfig command at CLI in order for the change to stick

  • Add users/services: it is sometimes difficult to add new users and services, but that is only because we haven't purchased a GUI to edit these.
  • Difficult to connect to: since it is difficult to add new users, there is no interface and we have to opt for a third-party GUI
  • No GUI: we have to opt for a third-party GUI to have a better visualization

We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

Best SIEM out there. Built for the serious security practioner. Has features you would expect in something much more expensive. Product continues to be refined and improved.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

I find their support to be excellent. From the FAQ's to the tech docs, it is very easy to resolve most issues. The few times we worked with a support technician, they were always quick to resolve our issue. We are very pleased with the overall level of support!

Implementation

Based on 37 answers
I have been satisfied with the service and the AWS for USM product. I am a bit concerned about the changing of product to the USM Anywhere and its price structure. I am hoping that we can keep our current price structure without any hidden costs. Other than that the sales team has worked very hard to give us a comparable price to the AWS for USM product. I also hope the the USM Anywhere is easy to use but has the same FIM features. Regardless, The USM team is extremely helpful, attentive and persistent. I would recommend them to anyone needing a product like theirs but was not concerned about price.

Alternatives Considered

I looked into Splunk, QRadar, but they were way too expensive and the reviews weren't always great. I used McAfee ESM extensively at my prior job and the product is probably the worst in the SIEM space. We moved to AlienVault from ELK which, while a cool product, didn't do any security event correlation and has a terrible search and log review and export. AlienVault is the only major SIEM comprised of over 200 open source tools I'd want to use anyway, so it does more than any SIEM with its HIDS agents, vulnerability scanning, asset discovery, etc. The included Open Threat Exchange subscription is also a major plus.

While SolarWinds may be much more advanced, Nagios will do 90% of what you need at a fraction of the cost.

Return on Investment

No answers on this topic
  • With the only investment being your time to install and configure, the ROI is pretty positive.
  • The product has a large community to help you fix any issues you have, which is also free.
  • There are also a ton of free plug ins and add-ons to expand Nagios' capabilities...nothing more but positive ROI.
