Modern incidents rarely succeed because attackers are brilliant. They succeed because trust is easy to exploit and the wrong action is allowed to proceed. Email remains a primary entry point for business risk. Identity and automated workflows can amplify the impact when a single message leads to access, payment, or data movement. GlobalGuard reduces that risk with resilient controls across critical business systems. We stop high-risk activity early, limit downstream impact, and reduce the cost and effort of response.
Founded in 2001, GlobalGuard is trusted by over 5,500 organizations worldwide.
Built to scale from small teams to global enterprises, across every industry including heavily regulated and high-risk environments.
Threats stopped before engagement, reducing incident impact and response cost.
Cloud-native infrastructure built to act earlier than reactive models, including hours faster and in some cases months faster.
TALK TO OUR TEAMMailGuard 365 is co-built with Microsoft to stack seamlessly with Microsoft 365, while other solutions integrate with Microsoft, Google and other environments to strengthen existing investments without disruption. Deployed without replacing existing platforms, devices, or workflows.

Applied business impact of intent-based protection
EMAIL-DRIVEN DECEPTION IS THE LEADING DRIVER OF CYBER INCIDENTS. Phishing and spoofing were the most-reported cybercrime type in 2024 in the FBI IC3 2024 report.
The FBI reports Business Email Compromise losses of $2.77B in 2024.
Delayed detection materially increases financial loss, regulatory exposure, and recovery time.
Controls that activate post-delivery allow trust to be exploited before action is taken.
Stop the action, to avoid the investigation, recovery, disclosure, & business interruption.
