Email Security

Safeguard your company and employees against data leaks, malware, spam and advanced threats

The Challenge

91% of hacking attacks begin with phishing or spear-phishing. Are your defenses ready?

Your organization can't afford a disruption to business operations — breaches cost millions and destroy reputations. You dread having to explain to customers and the media how sensitive information got into the wrong hands. Protecting against routine spam, viruses and malware is important, but you also need help responding to new threats and challenges that your current security infrastructure just wasn't designed for.

Even with training, 23%* of phishing emails are still opened. So protecting the company against human error is a top priority.
