Best 9 Proofpoint Alternatives for Email Security (2026)

• Custom rules engine uses AI agentic automation and LLM analysis to detect advanced email threats like credential phishing and executive impersonation.
• Secures sensitive inbox content (OTPs, password reset links, sensitive files) with additional MFA to contain blast radius before data can be reached.
• File security and identity controls for Google Workspace and Microsoft 365 restrict actions available to compromised cloud accounts.
• OAuth app remediation automatically identifies and revokes third-party tokens including connections to AI tools accumulating across environments.
• Deploys via API with no MX record changes or mail routing disruption.

Material is highly effective at slowing down attacks and limiting the exposure of user data, according to reviews of the service written by security teams. Security teams also highlight the automated remediation and phishing investigation capabilities as significant time savers for analysts.

Deploying the service is very straightforward, and reporting is another strength of the platform. Some customers do say that some rules can require advanced configuration, but the Material support team is helpful and responsive.

Proofpoint is a serious product, and teams running it are catching real threats. The case for Material isn’t that those teams are wrong; it’s that perimeter defense is one part of a larger problem. What happens to the attacker who gets through, or who bypasses email entirely via OAuth or session hijacking? Proofpoint doesn’t have an answer for that. Material does: inbound detection, sensitive data lockdown, identity controls, and continuous OAuth monitoring, all in a single platform that deploys via API alongside your existing stack, no MX record changes, no mail routing disruption.

If your team is evaluating alternatives to a perimeter-focused tool and needs a platform that covers the full workspace, not just the door, Material is worth a serious look.
