With AI-assisted voice cloning and spoofing attacks rising in late 2026, Apple quietly introduced a powerful anti-fraud tool in **iOS 27** and **iPadOS 27** called **Impersonation Risk Detection**—yet as [9to5Mac](https://9to5mac.com/2026/10/20/ios-27-adds-scam-prevention-feature-to-iphone-heres-how-to-enable-it/) and [ZDNET](https://www.zdnet.com/tech/ios-27-impersonation-risk-detection-security-feature/) point out, the toggle is switched off by default.

## What Does Impersonation Risk Detection Do on iOS 27?

When enabled, the system provides supported communication and financial apps with on-device risk signals that flag suspicious caller metadata, spoofed contact profiles, and high-pressure social engineering patterns.

### 3 Steps to Activate Scam Protection on Your iPhone

- **Open Settings:** Launch the **Settings** app on any iPhone or iPad running iOS 27 or iPadOS 27.
- **Navigate to Privacy & Security:** Scroll down and tap **Privacy & Security**.
- **Toggle On Protection:** Select **Impersonation Risk Detection** and switch the toggle to the green ON position.

> Taking ten seconds to enable Impersonation Risk Detection gives iOS 27 users an immediate on-device shield against bank and government spoofing scams.

## Why Apple Left the Setting Opt-In at Launch

Apple traditionally introduces behavioral security heuristics as opt-in features first to minimize false positives and preserve strict on-device privacy guarantees.
