Mobile Device Security for Small Business: Protecting iPhones and Androids at Work

Phones now hold work email, calendars, files and authentication prompts, yet they are often the least managed devices in a company. A few simple settings and a clear policy close most of the gap, whether the phone is company-owned or personal.

The basics for every phone

• Keep iOS and Android up to date, and remove phones that can no longer receive security updates.
• Require a passcode or biometric lock and automatic screen lock.
• Enable device encryption (on by default on modern phones when a passcode is set).
• Install apps only from the official app stores.

Protect work accounts

Use MFA for Microsoft 365 or Google Workspace, and consider a managed work profile or app protection policy so company data stays separate from personal data. This is especially useful with a bring-your-own-device policy.

Be careful with text and QR code scams

Scam messages and QR codes that lead to fake login pages are common on phones because the screen hides the full link. Staff should treat unexpected texts the same way they treat unexpected email.

Have a lost-phone plan

Know how to lock or wipe a device remotely, sign out active sessions, and reset the account password. Practice the steps once so they are familiar.

Public Wi-Fi

Avoid handling sensitive work on open networks, and prefer your phone’s own connection or a trusted VPN when traveling.
