Staying Ahead of K–12 Email Threats: How Aldine ISD Protects 39,500 Mailboxes

Email security for K–12 districts is harder than it looks. Schools are facing a surge in phishing, account takeover, and socially engineered attacks that blend seamlessly into everyday communication — and existing defenses are no longer keeping up.

Aldine Independent School District knows this firsthand. Protecting 39,500 mailboxes across one of Texas's largest school systems, Aldine was seeing advanced attacks slip past native controls while manual phishing triage drained their cybersecurity team. After adding behavioral AI to their stack, they now stop 22,700 advanced attacks per month and have neutralized 23 account takeovers.

In this fireside chat, we'll cover:

• How the threat landscape for K–12 email has evolved and why existing defenses fall short.

• Where native controls in platforms like Google Workspace and Microsoft 365 leave districts exposed.

• How behavioral AI catches the socially engineered attacks and account takeovers that rule-based tools miss.

• How Aldine’s security team reclaimed hours of manual work through automated detection and response.

If you’re responsible for email security at a K–12 district, this session gives you a real-world benchmark and practical steps you can take back to your team.
