I'm the Security Officer for the FreeBSD operating system... does that count? :-)

EDIT: I should add that this is one of the main reasons I got started in the field of online backups: There were lots of online backup solutions available, but I wasn't impressed with their security -- and due to being FreeBSD Security Officer, I tend to have sensitive information (e.g., about unannounced security vulnerabilities in OpenSSL/BIND/Sendmail/Apache/etc), making it absolutely essential that my backups be secure.
