AlienVault OSSIM

If this is your first experience with a SIEM, this one can get you started. Take the time to learn the ins and outs of the product and you'll most likely be satisfied with it if your company is an SMB. If you need compliance reports, OSSIM is too small for you, you'll need to go with USM or USM Anywhere.

Nessus

Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.

Pros

AlienVault OSSIM

  • Asset discovery. Once installed in a centric, network-accessible server, OSSIM can poll all your endpoints with common protocols (SSH, SNMP, WMI) to detect and discover site-wide assets to monitor. You only need to group them by your own criteria once added to the product.
  • SIEM Event Correlation. You can define quite complex correlation rules to detect possible suspicious or malicious actions or attempts in your network, in order to categorize them as real threats or as false positives, thus streamlining your risk assessment and management.
  • Ease of installation. The entire AlienVault OSSIM is self-contained in an ISO file, which can be burned into a DVD or just mounted in your server of choice (physical or virtual) for deployment. The installation process is automated and quote verbosed, with options for static IP, email messaging and others.
  • Ease of access. Being AlienVault OSSIM a self-contained appliance, it can be accessed via web by any device that supports a web browser, being that desktops, workstation, mobile devices, etc. The OSSIM dashboard and other features are automatically rearranged to adapt to the particular device being in use.

Nessus

  • With Nessus we can find the missing critical patches for a server or workstations.
  • Nessus points out any vulnerable or outdated software Technologies used in the system, thus eliminating any chances for security flaws being turned up.
  • Nessus typically points any configuration level issues in accordance with the OWASP guidelines. Even the configuration of SSL related which are most of the time handled by some vendors or 3rd parties.
  • Nessus not only lists out these Vulnerabilities but describes clearly the vulnerabilities in details with its thousands of plugins updated regularly, the tool also recommends solution with practical details of easy implementation.

Cons

AlienVault OSSIM

  • The reports are clunky and a bit tedious to parse through.
  • Sometimes there's so much noise it's hard to tell what a true positive is. There are lots of false ones that trigger alerts but are normal behavior in many environments.

  • Interaction with some other tools like Metasploit.

AlienVault OSSIM is far easy to use and manage - provided you know what you're doing. As any SIEM application, there is some background knowledge required in order to take advantage of the product's functionalities, such as the log correlation and analysis. Other than that, the application is quite usable and robust.

It's very much a plug and play application that the user can go into with limited knowledge and set-up scans in minutes.

AlienVault OSSIM support has been very good. I have not had an issue that they were not able to quickly identify and provide a fix for. They are very quick to respond to open cases and are very knowledgeable in the product, which makes troubleshooting issues fast and solutions are provided quickly.

AlienVault OSSIM

Best bang for the buck. Darktrace did not perform even close to AlienVault. I ran them concurrently. AlienVault consistently found issues that Darktrace didn't pick up, and the Darktrace incidents were false positives. At one point, Darktrace stated I had 2,000 servers and I have 112.FortiSIEM is an awesome package but it's more then I need (or can afford). I would need to add staff, for at least the first year or so, just to get it setup and configured correctly.

Tools like Qualys, Rapid7 stack up well against Nessus, but I think Nessus is superior overall when compared to them, given the features it has.
