Stingrays have been a subject of controversy due to their wide-ranging impact, ensnaring various devices without discrimination. iOS 17’s Lockdown Mode offers protection against these intrusive tactics, enhancing user privacy and security.
Anti-Web Tracking Features in Safari
iOS 17 introduces significant enhancements to Safari, Apple’s web browser, by stripping tracking information from web addresses that could be used to uniquely identify a device and track users across the web. This proactive measure makes it substantially more difficult for websites and advertisers to monitor an individual’s online activities
Users have the flexibility to enable this feature in Safari settings, applying it either exclusively during private browsing sessions or across all browsing activities. Importantly, this added layer of privacy protection does not disrupt the seamless browsing experience users are accustomed to.
Check In: Enhanced Safety Measures
One of the standout features of iOS 17 is “Check In,” a new functionality that allows iPhone owners to share their expected arrival time at a destination with friends. This feature actively monitors the user’s real-time location and can send alerts to designated contacts if any irregularities or safety concerns arise during the journey.
What sets Check In apart is its robust end-to-end encryption of location data. This encryption eliminates the need for third-party apps that have, in the past, compromised user location data by selling it to advertisers and data brokers. With Check In, user safety and privacy take center stage.
Live Transcription: Combatting Spam and Scam Calls
For individuals tired of dealing with spam or scam calls, iOS 17 offers a game-changing solution – Live Transcription. Instead of answering or declining a call, both of which can tip off the caller that the line is active, Live Transcription converts the caller’s voice into real-time text displayed on the screen.
This innovative feature empowers users to quickly assess incoming calls without engaging directly with potential scammers. It adds an extra layer of security to the iPhone experience, reducing the risk of falling victim to fraudulent calls.
In the following sections, we will explore each of these features in greater detail, examining their significance and how they contribute to a safer and more secure iPhone ecosystem.
Lockdown Mode: Your First Line of Defense
Lockdown Mode has long been a valuable security feature in iOS, and with iOS 17, it receives significant enhancements that extend its protective reach to Apple Watch. Let’s take a closer look at how Lockdown Mode operates and the new safeguards it offers.
How Lockdown Mode Works
Lockdown Mode is designed to thwart potential threats by selectively deactivating specific iPhone and Watch features that have historically been exploited by spyware developers. These features, including iMessage and HomeKit, are temporarily disabled, making it significantly more challenging for unauthorized individuals to breach the device and access sensitive information.
Expanding Protection to Apple Watch
With the inclusion of Apple Watch in Lockdown Mode’s protective umbrella, users can now benefit from enhanced security across multiple Apple devices. This is particularly crucial in light of recent exploits that have exposed vulnerabilities in Apple Watch, highlighting the need for comprehensive security measures.
Geolocation Data Privacy
In addition to its core security functions, Lockdown Mode in iOS 17 goes the extra mile to safeguard user privacy.

This proactive measure prevents inadvertent exposure of an individual’s location when sharing images, adding another layer of protection to users’ personal information.
Guarding Against Unsafe Wi-Fi Networks
Lockdown Mode’s defensive capabilities extend to network security as well. It prevents iPhones from automatically connecting to non-secure Wi-Fi networks. This is a critical safeguard, as joining such networks can expose an iPhone’s network traffic to potential analysis by individuals on the same network, posing a significant security risk.
Blocking 2G Cellular Networks
iOS 17’s Lockdown Mode takes an important step in combating cellular-based exploits. It actively blocks connections to 2G cellular networks, which are often leveraged by cell site simulators, commonly known as “stingrays.” These devices are used by law enforcement to deceive nearby phones into connecting to fake cell base stations, allowing them to track phone locations and intercept calls and messages.
Anti-Web Tracking Features in Safari: Protecting Online Privacy
Safari, Apple’s web browser, receives notable upgrades in iOS 17, aimed at enhancing user privacy and thwarting online tracking efforts by websites and advertisers.
Stripping Tracking Information from Web Addresses
One of the core features of iOS 17’s Safari browser is its ability to strip tracking information from web addresses. This information is often used to uniquely identify a user’s device and monitor their online activities across different websites. By removing this tracking data, Safari makes it significantly more challenging for websites and advertisers to build comprehensive user profiles.
User-Friendly Privacy Settings
To ensure a seamless browsing experience, iOS 17 provides users with the flexibility to customize their privacy settings. Users can choose to enable the tracking information stripping feature exclusively during private browsing sessions or apply it to all browsing activities. This user-friendly approach empowers individuals to take control of their online privacy without sacrificing convenience.
Check In: Empowering Safety and Privacy
iOS 17 introduces “Check In,” a feature designed to enhance user safety during their journeys. By sharing their anticipated arrival time with friends, iPhone owners can enjoy added security and peace of mind.
