AI Agent Email Security

Most teams use Gmail, Outlook, and Exchange. AI agents go after the weakest link. PortEden gives you one security layer across every email provider, with consistent rules, per-provider customization, and a single audit trail.

Email CLI

PortEden's CLI connects to Gmail, Outlook, and Exchange from one tool. Install it once, define global or per-provider security rules, and every email request from any AI agent is filtered automatically across all your inboxes.

The Problem

Giving AI agents direct access to your data is risky. Here's what can go wrong.

Inconsistent Security Across Providers

Gmail, Outlook, and Exchange each have different permission models, and AI agents exploit whichever provider has the weakest controls.

Provider-Specific Prompt Injection Vectors

Gmail and Outlook render HTML differently, so attackers craft provider-specific payloads that a single-provider defense will miss.

Fragmented Audit Trails

Email access logs are scattered across Google Admin, Microsoft 365 Compliance, and Exchange Server, making it impossible to see what an agent accessed today.

How PortEden Protects You

Six layers of security between AI agents and your data.

Visibility Controls

Set consistent visibility rules across Gmail, Outlook, and Exchange, or customize per provider with full content, headers only, or field-level redaction.

Action Limits

Per-provider action policies: read-only on legal's Outlook, draft-only on marketing's Gmail, all managed from one policy engine.

Contact Rules

Add a contact or domain to the blocklist once and it's enforced everywhere across Gmail, Outlook, and Exchange.

Time Windows

Set time boundaries per provider or globally: last 30 days for Gmail, last week for Outlook, last 24 hours for Exchange.

  • Each email provider secured separately, or not at all
  • AI agents exploit the provider with the weakest controls
  • Audit logs scattered across Google Admin, M365 Compliance, and Exchange
  • Adding a new provider means building security from scratch
  • No way to enforce consistent contact rules across inboxes

With PortEden

  • One security layer across Gmail, Outlook, and Exchange
  • Consistent rules enforced regardless of which inbox is accessed
  • Single audit log spanning every provider and every agent
  • New accounts inherit global rules automatically on connection
  • Contact blocklist applied once, enforced across all providers

Frequently Asked Questions

How do I secure my email from AI agents?
PortEden acts as a data firewall between AI agents and your email providers. Install the CLI, connect your Gmail, Outlook, and Exchange accounts, then configure visibility controls, action limits, contact rules, and time windows. Every agent request is filtered through your rules before any email data is returned, and you get a unified audit log across all providers.
Can PortEden protect both Gmail and Outlook at the same time?
Yes. PortEden provides a single security layer across Gmail, Outlook, and Exchange. You can set global rules that apply to all providers or customize per provider. For example, read-only access on legal's Outlook but draft-only on marketing's Gmail. All activity is logged in one audit trail regardless of provider.
What happens when I add a new email provider?
When you connect a new email account, your existing global rules apply automatically. The new provider inherits your contact rules, visibility settings, action limits, and time windows. No reconfiguration needed. You can then add provider-specific overrides if needed.
How does PortEden handle email attachments?
PortEden's visibility controls extend to attachments. You can allow agents to see attachment metadata (filename, size, type) without accessing the content, block attachments entirely, or allow full access. These rules apply consistently whether the attachment is in Gmail, Outlook, or Exchange.
Can I set different rules for different AI agents?
Yes. PortEden supports per-agent policies across all providers. Claude can have read-only access to the last 7 days of Gmail, while ChatGPT gets draft-only access to Outlook with specific contacts blocked. Each agent gets its own scoped access and audit trail.
