Outbound Email Encryption

Encrypt Every Send.
Satisfy Every Audit.

Sensitive data leaves your organization over email every day.
Now it leaves encrypted, whether by policy that detects regulated content or by the sender when the moment calls for it.

What Happens if Your Team Sends Exposed Data?

Breaches, fines, and audit failures don't always require a sophisticated attacker. Exposed data can be caused by a policy gap or a distracted employee, but the regulatory and reputational fallout is just as expensive. 

Data Exposure Consequences

  • Loss of Trust: Decreased customer and partner trust doesn't appear on an incident report. It shows up in lost renewals, stalled partnerships, and clients who quietly move their business. 
  • Regulatory Penalties: HIPAA, GDPR, FERPA, SEC, FINRA, and a growing list of state mandates carry enforcement that goes well beyond fines. Investigations, mandatory disclosures, and operational restrictions follow. 
  • Data Exfiltration: PII, partner data, or intellectual property in the wrong hands leaves your organization exposed financially and operationally. 

Outbound Email Security Challenges

  • Internal Threat: Not a sophisticated threat actor. A misaddressed email, a reply-all to the wrong thread, an unencrypted attachment. Nothing looks malicious until the damage is done. 
  • Encryption Inconsistency: Urgency, ambiguity, and "I thought it was internal" create gaps that auditors, regulators, and cyber insurers penalize. 
  • Tool Sprawl: Standalone encryption products add a new console, a new workflow, and a new vendor relationship. Each one creates another gap for something to fall through. 

Deploy Encryption
on Your Terms

IRONSCALES offers two paths to outbound encryption. Use them independently or together to match your security posture and compliance requirements.

  • Elective Encryption: Sender-initiated encryption via Outlook add-in or a [secure] keyword in the subject line. Gives users direct control for ad hoc sensitive communications. No workflow change, no training required.
  • Policy-Based Encryption: Automatic encryption triggered when predefined policies detect sensitive data in recipients, message bodies, or attachments. Protection applied at send. Zero reliance on user behavior. 

Encrypt Without the Overhead

Every capability is built into the same IRONSCALES console you already use for best-in-class inbound email security.

  • Frictionless Recipient Access: Recipients open encrypted messages through a secure portal with a one-time passcode. No account creation. No software. Secure reply and reply-all supported.
  • Multi-Tenant Scale for MSPs: Centralized policy management across every client tenant. Reusable templates for regulated industries. Deploy encryption as a new compliance-driven service tier without adding headcount or custom configurations.

Data Security Regulators Require

All of our encrypted communications are sent using AES-256 encryption, both in transit and at rest. IRONSCALES helps our customers and partners attain and maintain compliance.

  • Healthcare (HIPAA): Securing PHI and PII in outbound patient and partner communications.
  • Financial Services (PCI DSS, SEC): Protecting payment card data and customer financial records from unauthorized disclosure.
  • Education (FERPA): Restricting access to student records transmitted over email.
  • Global Operations (GDPR): A documented technical safeguard for personal data, satisfying Article 32 requirements.

Frequently Asked Questions

Is IRONSCALES adopting a Secure Email Gateway (SEG) approach?

No. IRONSCALES Email Encryption is outbound protection for sensitive data leaving Microsoft 365. It does not sit inline for inbound email filtering, does not require MX record changes, and does not alter your existing mail flow. Encryption is added as an outbound control through Microsoft 365 transport rules. Disable the rule and mail flow instantly reverts.

Do recipients need to create an account?

No. Recipients receive a secure notification with a protected link and authenticate using a one-time passcode delivered to their email. There is no account creation, no password setup, and no software to install. This is a meaningfully simpler recipient experience than alternatives that require portal accounts.

What email platforms are supported?

IRONSCALES Email Encryption currently supports Microsoft 365 environments. Additional platform support is planned for future releases.

Can it block or quarantine outbound emails?

The primary action when sensitive data is detected is autonomous encryption to limit access. When keyword-based policies match, messages are automatically encrypted rather than blocked or quarantined, allowing business communication to continue while protecting sensitive content in transit.

How does IRONSCALES encryption work for MSPs?

MSPs manage encryption policies across all client tenants from a single console. Reusable policy templates for regulated industries (healthcare, finance, education, insurance) simplify deployment and reduce per-tenant configuration overhead. Encryption becomes a new billable service tier without requiring additional infrastructure or headcount.

Can encrypted emails be opened by users outside of Outlook?

Decryption happens in the secure web portal, not directly in Outlook. Recipients click the secure link in the notification email, authenticate with a one-time passcode, and access the full message and attachments in the portal. Secure reply and reply-all are supported through the portal interface.

What happens if a user forgets to encrypt a sensitive email?

With elective encryption only, the email sends normally without encryption. With policy-based encryption enabled, encryption is applied automatically when sensitive content patterns are detected, regardless of whether the sender remembered to encrypt. This is why the combination of both deployment paths provides the strongest protection.
