### Device2Mail (D2M) — Mobile Email Device Authentication

Device2Mail (D2M) is an advanced security solution designed to safeguard corporate email access on mobile devices. By ensuring that email data can only be accessed from trusted and managed devices, D2M eliminates the risk of unauthorized entry, even if user credentials are stolen.

#### The Problem It Solves

Today, mobile email clients are mostly developed by global vendors and rely solely on a username and password combination to access on-premise Exchange servers via the ActiveSync protocol. This creates a major security vulnerability: if credentials are compromised, attackers gain unrestricted access to sensitive corporate data.

Security frameworks and regulations, including ISO/IEC 27001, the Information Security Guide of the Turkish Presidency's Digital Transformation Office, and NIST standards, all prohibit sole reliance on usernames and passwords for system access.

D2M addresses this gap by introducing a device-based secondary authentication layer for mobile email access, transforming the way enterprises protect their digital assets.

#### Risks Without D2M

- **Credential Theft Exposure** — Without D2M, stolen credentials grant attackers full access to corporate emails via ActiveSync.
- **Weak Policy Enforcement** — Exchange quarantine policies may overwhelm administrators with device approval requests.
- **Regulatory Non-Compliance** — Failing to apply MFA for mobile email access violates international security standards.
- **Uncontrolled Device Access** — Organizations cannot properly manage or revoke access when an employee's device is lost, stolen, or compromised.

#### Key Features of Device2Mail (D2M)
