Email Security

The Problem

Nearly all cyberattacks leverage email. Why? It’s an always on, trusted communications channel that can be easily compromised. Attacks are fast-moving and relentless. This modern threat landscape requires an equally modern approach.

The Relationship between Adoption & Risk 

96%

of companies experienced a phishing attack last year

95%

of cyber breaches can be traced back to human error

94%

of all successful cyber attacks begin with an email 

22%

of malicious emails are delivered after being scanned by M365

Emails are the #1 target

Cyber criminals ranging from state sponsored organizations to teenagers sitting in their basements are all capable of launching a successful email attack. Phishing software is widely available online, costs $0, and as anyone who has experienced a CAS penetration test can attest to, is very effective.

The main reason phishing attacks are so effective comes down to the difficulty in recognizing them. An estimated 97% of employees are unable to identify a sophisticated phishing email, and even cyber security experts struggle to identify well executed attacks. Taking the burden off employees, email security filters are supposedly the answer, but there is an incorrect belief that email security is a commodity and many organizations rely on the free email security that comes bundled with their email platform. 

It's no secret that email security is hard - and at the end of the day most services just aren't very good at detecting malicious emails. Microsoft, the most widely used email provider in the world, has a false negative rate of 22%. In other words Microsoft is only 78% effective in detecting malicious emails.

At CAS, we believe 78% isn't good enough.
