1. A non-transitory computer-readable medium embodying a program executable in at least one computing device to ensure security of email attachments, comprising code that:

  • accesses an email sent to a client device from at least one email service, the email comprising an email attachment;

    identifies a rule associated with the email, the rule specifying that the email attachment must be removed from the email prior to displaying the email to the recipient;

    removes the email attachment from the email in accordance with the rule;

    encrypts, without user interaction, the removed email attachment with a cryptographic key accessible to a secure container application, the secure container application being provided separately from an email application used to access the email;

    generates an encrypted email attachment from the email attachment using the cryptographic key accessible to the secure container application; and

    modifies the email to include the encrypted email attachment.
