AI Data Leak Prevention

OWASP's Agentic AI Top 10 lists Data Exfiltration (#10) as a critical risk. AI agents summarize emails into shared docs, forward messages, and carry sensitive data across tool boundaries, all without you seeing a thing. PortEden stops exfiltration at the source.

The Problem

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

Data Exfiltration via Tool Output

AI agents carry sensitive email data into shared docs, Slack, and other tools, making every tool output a potential exfiltration channel.

Sensitive PII in Email Bodies

Salary figures, SSNs, medical info, and legal discussions sit in email bodies that agents can read, and standard OAuth scopes have no way to redact them.

Invisible Data Forwarding

Agents with send permissions can forward emails or create auto-rules, moving data out of your inbox with no visible trace.

How PortEden Protects You

Six layers of security between AI agents and your data.

Visibility Controls

Strip sensitive fields, redact bodies, and hide attachments before agents see them so the data can never be leaked.

Contact Rules

Block access to emails from HR, legal, medical, and personal contacts so sensitive conversations stay invisible to AI.

Data Reduction

Field-level redaction removes PII, financial data, and confidential markers so only the information the agent needs gets returned.

Audit Trail

Every piece of data returned to an agent is logged with full per-request, per-agent detail for compliance.

Get Started in 3 Steps

1

Install the CLI

Install PortEden CLI and connect your email accounts via secure OAuth.

2

Configure Data Controls

Set visibility controls, contact rules, and data reduction policies for what agents can access.

3

Monitor & Audit

Every agent request is logged with full details of what was accessed, returned, and blocked.

Without vs. With PortEden

Without PortEden

  • AI agents can read and summarize any email content, including sensitive PII
  • Email data flows freely from inbox to Slack, docs, and other tools via agents
  • No visibility into what data agents extract from your mailbox
  • Agents with send permissions can forward emails without your knowledge
  • Traditional DLP can't monitor AI agent tool-to-tool data flows

With PortEden

  • Visibility controls strip sensitive fields before agents see them
  • Contact rules hide HR, legal, and personal emails from AI entirely
  • Field-level redaction removes PII, salary data, and confidential markers
  • Full audit trail of every piece of data returned to every agent
  • Action limits prevent agents from forwarding or creating mail rules

Frequently Asked Questions

How do AI agents leak email data?
AI agents leak data in several ways: summarizing sensitive emails into shared documents or Slack channels, forwarding emails to unauthorized recipients, creating auto-forward rules, or simply including confidential information in their responses to other tools. PortEden prevents this by controlling what data agents can see in the first place.
What is OWASP Agentic AI Top 10 #10 and how does PortEden address it?
OWASP Agentic AI Top 10 #10 covers Data Exfiltration, which is the risk that AI agents extract sensitive data through tool outputs. PortEden addresses this by applying visibility controls and field-level redaction before data reaches the agent, stopping exfiltration at the source rather than trying to detect it after the fact.
Can PortEden prevent AI agents from accessing emails with PII?
Yes. PortEden's contact rules can block access to emails from HR, legal, and medical contacts entirely. Additionally, data reduction strips sensitive fields like salary figures, SSNs, and confidential markers from email content before the agent sees it.
How is PortEden different from traditional DLP solutions?
Traditional DLP monitors outbound data flows and tries to detect sensitive content after it's been accessed. PortEden works upstream. It controls what data AI agents can see in the first place. Rather than detecting leaks after they happen, PortEden prevents the agent from ever having access to sensitive data.
Does PortEden log what data AI agents access for compliance?
Yes. Every request from an AI agent is logged with full details: what was requested, what was returned, and what was blocked or redacted. This audit trail provides the evidence trail that compliance teams need for GDPR, HIPAA, and SOC 2 requirements.
