We don't encrypt it. We don't send it anywhere. You have to come to us to read it.
Ex: Your routers, switches, RAID storage etc. are not immune to rootkits. However, if your message from A to B is encrypted and only decrypted locally by B, you've limited the exposure of this information.
There are no passwords - we use our own CA system, PKI, carefully selected cipher suites, physical security, mutiple vendors' products, logical isolation, tiered architecture, an IDS system, mirrored environments, tamper detection and automatic key disposal.
And I still don't sleep because there are a thousand ways around it all.
Still, we have insurance.
Integration between various companies, nothing more. We're a hub.
