Your Organization Runs on Email

    It’s the main way you communicate internally and externally and you rely on it being available all day, every day.

    It’s a gateway to other critical IT systems and home to a treasure trove of corporate information your employees value. For all it offers, email needs to be protected and managed or it risks exposing your organization and your data to attack. Your customers and your supply chain are far too valuable to take that chance. It also needs to be effectively archived to meet growing compliance, e-discovery and legal obligations.

    Our Approach to Email Security

    What's your email security approach?

    Traditional security approaches are no longer effective. Attack methods are quickly evolving and growing more sophisticated, targeted and dangerous. Right now, the industry is faced with email-borne threats like phishing attacks delivering malicious attachments and URLs; impersonation fraud fueled by social engineering and aimed at tricking employees to wire-transfer money or send company personally identifiable information; and ransomware attacks that can encrypt your data and take entire systems offline.

    Ignoring these advanced threats, and sticking with legacy security capabilities or deploying a defense-only security strategy, puts your data, business operations, employee productivity, and reputation at risk.

    It's time for a new approach.
