Why Email Remains the Most Exploited Attack Vector in the USA

Despite decades of security investment, email remains the number one delivery mechanism for cyberattacks. Phishing campaigns have grown more sophisticated. Business email compromise scams now cost US businesses billions annually. And the rise of AI-generated spear phishing means your employees are being targeted with messages that look and read exactly like legitimate communications from people they know. Standard email filters and spam blockers were not designed to catch these attacks. PlutoSec deploys layered email security controls that go well beyond basic filtering, combining advanced threat detection, authentication enforcement, and user-level controls that stop attacks before they reach the inbox.

Advanced threat protection deployment for Microsoft 365 and Google Workspace environments

DMARC, DKIM, and SPF implementation and policy enforcement to stop domain spoofing

Business email compromise (BEC) and executive impersonation detection

Sandboxing and detonation of suspicious attachments and URLs

Anti-phishing controls including link rewriting and real-time URL analysis

Email security posture assessment and configuration hardening

Every Major Breach Has an Email Somewhere Near the Beginning

How PlutoSec Builds Your Email Security Architecture

Email security is not a single product. It is a set of layered controls that each catch different attack types. Our approach combines the right technology stack with the configuration precision that makes the difference between genuine protection and checkbox compliance.
