Email Security Vulnerabilities Demand Dual-Layer Protection for MSPs

• •Email is the top attack vector, with modern phishing tactics often appearing legitimate.
• •Dual-layer email security combines SEG for pre-delivery filtering and API for post-delivery remediation.
• •The human element is involved in around 60% of breaches, highlighting the need for enhanced email security.

Email remains the primary entry point for cyberattacks, with modern threats often appearing legitimate. Managed Service Providers (MSPs) must adapt their email security strategies to address sophisticated phishing attacks that exploit trusted domains and AI-generated content. The human element is involved in approximately 60% of breaches, with AI-generated phishing emails achieving click rates of up to 54%. Legacy email solutions are insufficient due to their reliance on signature-based detection. Dual-layer email security, combining Secure Email Gateway (SEG) and API-based protection, is essential for effective threat detection and remediation. SEG filters threats before delivery, while API-based protection offers visibility and response capabilities post-delivery. This dual approach enables MSPs to protect against various threats, including phishing, Business Email Compromise (BEC), and insider threats. As cyber threats evolve, the integration of these layers becomes a foundational element of strategic defense for MSPs.
