Why we do what we do.

    Security breaches, data leaks and email-based attacks are a real threat to your organization. Now, more than ever, you need a new approach to email security and management. Don’t let the limitations of traditional technologies prevent you from protecting email and corporate information.

    We have made it our mission to mitigate the risks you face from email, and support you in reducing the cost and complexity of protecting yourself by moving this workload to the cloud. We live and breathe cloud technology. We developed our proprietary cloud architecture to offer you comprehensive email security, service continuity and archiving in a single subscription service. Our goal is to make it easier for you to protect your business in today’s fast-changing security and risk environment.
