For businesses looking to follow the best web security practices, email encryption is a must. Encrypting and digitally signing your emails will help your company avoid accidental data exposure, breaches of privacy, and other security missteps that could lead to serious implications. Luckily, CPAC solutions add encryption strength up to 256-bit and a greater sense of security to your email communication.

CPAC provides true end-to-end encryption between the sender and the recipient. This ensures that once the email leaves your network, it can never be intercepted and decrypted by https proxies, man-in-the-middle attackers, packet-sniffers, or any other hackers.

Each certificate uses highly secure PKI (Private Key Infrastructure) to prove a user’s identity to a remote server or computer, which is much quicker and far more cost-effective than using physical tokens.

Setting up CPACs is extremely easy! And after the initial installation is complete, all of your servers will require that each user present their certificate in order to be accessed – in addition to username and password. This will help ensure that you have all of the checks and balances in place to keep unwanted users off your servers!

CPACs let you to easily sign important company documents. This allows you to identify yourself as the document signer and prove that the document has not been tampered with in any way since it was signed. These certificates will also help you migrate from ink to paper based workflows on items like document sign-offs, contracts, offer sheets, archiving and internal request forms. CPACs can also be used in tandem with or as a complete replacement for the visible signature feature in Microsoft® Office products.

If your business supports remote access to servers that contain vital customer or corporate data, relying on passwords as the sole gatekeepers is simply not enough with the stakes being so high. You’ll want a stronger guarantee that the person accessing an online account or network resource is a legitimate employee, not a hacker that has managed to steal a username and password – which is much easier than you think!

CPACs mitigate this risk by setting up two-factor authentication or both employees and customers. Two-factor authentication is the industry standard utilized by banks all over the world.
