Description

Guardian Digital protects against email threats such as phishing, zero day exploits, and crippling ransomware attacks. These are just some of the many threats email users face every single day. Email security is a business security issue, as more than 90% of cyber attacks originate in an email. A purpose-driven solution is the best way to protect email. It closes critical security gaps in Microsoft 365 and Google Workspace. It also provides remote support, expert setup and ongoing remote management. We provide real-time cybersecurity business insight to help you assess your current risk profile and protect you against the threats that all businesses face when using email.

Description

OpenText Core Email Threat Protection provides comprehensive defense against the most common and dangerous email-based attacks, ensuring businesses stay protected across every stage of communication. It filters malicious messages from all directions—whether inbound from unknown senders, outbound from internal systems, or lateral between employees. With features like link protection, attachment sandboxing, message retraction, and AI-powered impersonation blocking, the platform proactively eliminates threats before they can cause damage. Organizations benefit from reduced risk of ransomware, financial fraud, and data breaches, all without disrupting legitimate communication. Deployment is fast, and the platform’s centralized dashboard allows security administrators to easily review events, enforce policies, and analyze trends. Mobile access extends visibility and management beyond the office, giving teams flexibility in fast-moving threat environments. Outbound filtering further preserves domain reputation and ensures compliance with regulatory requirements. Supported by decades of security expertise, OpenText Core Email Threat Protection helps businesses simplify cybersecurity while maintaining high operational resilience.
