AlienVault OSSIM vs Rapid7 InsightVM (Nexpose)

• 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.

• Being a vulnerability scanner tool, its purpose is to scan the systems to find the vulnerabilities. We can define the assets like IP address for the scans and it also allows to either schedule the scan at a preferred time or start the scan immediately. Upon completion of the scan, this tool can result provide the details like host type, OS information, hardware address, along with the vulnerabilities.
• Rapid7 Nexpose has a list of templates to perform the scan. Once the templates are defined then the scans are performed accordingly.
• It also contains an option to add credentials/authentication using passwords, usernames, private keys to perform the credential-based scans which I think is a great feature.

• 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.

• In comparison to Tenable SecurityCenter we saw it didn't exactly find the same vulnerabilities which we would assume it should have
• We rely on a ticketing system and not our VM tool to assign tasks so wasn't too useful having that in there
• Filtering capabilities aren't as good as its competitors
