The scandal that has enveloped former CIA director David Petraeus has shown Gmail and Web-based email services are not completely safe zones.

In their article published on Politico Pro, Michelle Quinn and Alex Byers illustrate the 5 Gmail lessons from David Petraeus affair on the limitations about privacy:

1. It’s not anonymous.
2. Government requests for access are increasing and Google and other services play ball.
3. You’re not in cyberspace.
4. A draft email folder does not offer magical protection.
5. Off-record chats can linger — somewhere.
