Contact Cornerstone Intelligence
Cornerstone Intelligence, LLC takes privacy and information security very seriously. Our everyday, companywide email is hosted by a secure, offshore email provider that mandates all connections to their servers use Transport Layer Security (TLS) and Secure Sockets Layer (SSL) encryption, both for webmail and IMAP/POP/SMTP email client access. This prevents eavesdropping, tampering, and message forgery on any communication between our computers and their servers.
They have full support for Perfect Forward Secrecy (PFS) with our encrypted connections, which ensures that even if they were somehow compromised in the future, no previous communication could be decrypted. All their connections in supporting browsers have been protected by PFS since July 2012.
Whenever we send a message to someone outside of our network, we have to send it across the open internet. Since January 2010, our offshore email provider has fully encrypted all connections between them and the receiving server whenever the other server supports it, preventing passive eavesdropping, tampering or forgery. Similarly, they have accepted encrypted connections for mail delivery to their servers since April 2009.
While communication between our computers and their servers is encrypted, any email that we send to another server may have to pass over the internet in an unencrypted form.
The only way to ensure end-to-end security with email is to use email encryption software such as Pretty Good Privacy (PGP) or Secure/Multipurpose Internet mail Extensions (S/MIME). Both of these systems require the creation of certificates, run on your computer, and are attached to your email client to encrypt/decrypt messages.
If you absolutely must ensure that your email communications stay secure, we recommend creating a free ProtonMail account, and communicating with us directly at attasj1 at protonmail dot com. If you already know how to use PGP Encryption and do not want to create a new ProtonMail account, our PGP Public Key is published on the right. Cornerstone Intelligence, LLC is the only investigation and open source intelligence company in Central Texas that offers a secure, encrypted method of communication to clients and potential clients.
We believe that human beings should live by reason, as individuals, with integrity, and with passion. Privacy allows that. Furthermore, we demand of our clients what we demand of ourselves: To demonstrate honesty and to show respect for the dignity of man, privacy, and for sound economic principles. All others need not apply. – Paul Rosenberg
