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.

Preventing Data Leaks

The majority of organizations have no solution for preventing data leaks. Don't be one of them.

Whether malicious or not, organizations simply can't afford to send sensitive information such as customer lists, financials, intellectual property or personally identifiable information externally without appropriate protection, if at all. With Mimecast D1 DLP & Content Security, powerful scanning and quarantine features mean data is stopped at the gateway or sent securely so sensitive information is protected.
