Why now

Attackers don't target infrastructure. They target people.

Email remains the primary entry point for modern attacks, not because organisations lack tools, but because attackers go after people, identities, and access.

The pathways Phishing, impersonation, malicious attachments, and compromised accounts.
Where they lead Ransomware, data loss, privileged account compromise, and lateral movement across cloud environments.

One convincing message to one busy person is still the shortest way in.

Beyond the gateway

The mailbox is the goldmine

Traditional email security filters what comes in. But the real risk is what's already sitting there: years of contracts, credentials, personal data, and financial records, dormant in mailboxes and one compromised login away from an attacker. Material's API-native, post-delivery approach protects the mailbox contents and the identities around it, and operationalises Zero Trust for email: uncovering the attacks that slip through, automating containment, and simplifying compliance.
