Secure your attack surface against phishing attacks.

Block phishing

Why email is one of the least secure ways to communicate today

Almost 15 years ago the Network Working Group officially labeled Simple Mail Transfer Protocol as ‘inherently insecure’. They said that anyone could impersonate a domain and use it to send fraudulent emails pretending to be the domain owner. Today, this is proven in the scale and breadth of the Business Email Compromise (BEC) attacks we see hitting headlines daily, whether successful or not.

The most common forms of BEC

Exact domain impersonations

Perhaps the most dangerous form as they can fool the majority of Secure Email Gateways. This is where a fraudster sends an email that looks like it came from your domain. This is because the underlying domain is not protected by protocols like DMARC.

“Friendly from” attacks

With minor manipulation, a criminal can change an email's display name to look like it's coming from a known sender. While easier to spot if the recipient digs into the email header, it’s enough to fool time-pressed individuals into clicking and compromising the organization's security.

Lookalike domain abuse

Finally, there are attacks that turn to using lookalike domains. This attack vector is massively growing, partly due to the fact that it’s impossible for an organization to defensively buy up and secure all possible permutations of its digital identity.

Secure your attack surface against phishing attacks

Email remains the greatest attack vector. It is a growing problem for businesses each day; without adequate defenses in place, they risk irrevocable damage to brand, reputation, and revenue.
