Phishing attacks, also known as CEO Fraud, is costing business and individuals over $40 million per year. An email could be received by a staff member in a companies financial department, wanting urgent payment of an attached invoice. The email may look 100% legitimate with all the correct signatures and details. But it could still be fraudulent. This is where an Identity Authentication Certificate can help, digitally signing and encrypting the emails sent. You will see the verified tick in your mail client, to know the email was sent from the "real" individual, and not a malicious fraudster.

These Certificate are also known as Secure/Multipurpose Internet Mail Extensions (S/MIME). They help to ensures the message integrity, so that senders and recipients of an email can verify that the content they are sharing is legitimate and trusted.

Remote access to servers is a great solution for business to allow more flexible work conditions. But relying just on passwords to these servers can be costly. They can easily become compromised. These Certificates help mitigate this risk by setting up two-factor authentication. This is an industry standard now for banks, healthcare and government organisations holding sensitive information.
