We use red seal for our security assessment of all new devices that come into my organization as well as those in production environments (we have several hundred thousand).
The tool is easy enough so non-technical employees can easily learn how it works without having IT do this work themselves! It's also very user friendly with good reporting capabilities via both API or web interface. I wish we could find better ways to integrate other tools like Cisco ASA/Nessus but they are working hard at making these integrations happen too. Our team has been able to quickly identify any issues within minutes after deploying them onto an environment which was previously taking days if not weeks before hand by using Red Seal alone.
