How to Properly Sanitize/Securely Wipe a FortiGate Firewall Before Disposal
We have a pair of older FortiGate 200B firewalls that have been out of use for awhile and collecting dust as they are no longer supported by FortiNet. Before I get rid of them, what is the process to wipe/erase/sanitize these firewalls to ensure no one can access our data/configs from these devices once they leave our possession?
Here is what I have done so far to both:
Performed a "exec factoryreset" from the cli.
Formatted the boot device from the cli configuration menu
Loaded new firmware images via TFTP
One of the units had a solid state drive that was used to store logs, I removed the drive inserted into a desktop and wiped it using our desktop sanitizing tools.
