Email security needed a new trust foundation, so we built it. Traditional approaches that make trust decisions based on message sources or content analysis aren’t enough anymore. They’re too easily spoofed and manipulated, especially with the rise of AI. That’s why Shield’s zero trust foundation is built around your unique communication patterns. By automatically learning who you interact with and how you handle messages, Shield creates a trust network of verified contacts. Our adaptive intelligence (AI) turns this behavioral data into personalized protection, delivering only the email you want with no extra effort required.
