iPhone security has been a major topic of discussion this month. Apple recently patched several security vulnerabilities and issued alerts urging users running older software to update their devices immediately. Meanwhile, Apple has officially asserted that its "Lockdown Mode" has proven entirely successful in thwarting hacker attacks. The company states that, to date, no device with "Lockdown Mode"—a specialized security feature launched approximately four years ago—has ever been successfully hacked.

What is Lockdown Mode?
Apple introduced "Lockdown Mode" for iPhone, iPad, and Mac devices in 2022. According to the company, this feature was designed to protect a select group of individuals—such as journalists, activists, and government officials—who, due to their work or identity, face a heightened risk of sophisticated and dangerous cyberattacks. However, average users typically do not encounter such threats. When this mode is enabled, your device does not function exactly as it normally would; instead, strict restrictions are imposed on various apps, websites, and features to safeguard the device against spyware.

What Do Security Experts Say?
It is not just Apple; leading independent cybersecurity experts worldwide have also acknowledged the robustness of this feature. Doncha O'Cearbhaill, Head of the Security Lab at Amnesty International—who has meticulously investigated dozens of spyware attacks—explicitly states that, to date, he has found no evidence of any iPhone being successfully hacked while Lockdown Mode was active. Similarly, the renowned "Citizen Lab" at the University of Toronto has confirmed in its reports that this feature has successfully thwarted attacks by some of the world's most dangerous spyware—such as Pegasus and Predator—which are notorious globally for their use in espionage. Google security researchers have uncovered a startling finding in their investigations: many spyware programs actually abandon their intrusion attempts midway upon detecting that Lockdown Mode is active on a device, fearing that the mode's stringent security measures could lead to their detection.

What Changes When Lockdown Mode Is Enabled?
When you enable Lockdown Mode on your device, significant changes are implemented in the system's operational mechanics to render its security virtually impenetrable. First and foremost, the functionality of your messaging app becomes restricted; except for select media types—such as photos and videos—all other attachments are blocked. Furthermore, links received within messages, along with their previews, cease to function.

Similarly, this mode has a profound impact on your internet browsing experience. Several advanced and complex web browser settings are disabled for security reasons. Consequently, some websites may load significantly slower or fail to function correctly. Since security is prioritized during this time, you may occasionally see "missing image" icons in place of a website's original fonts or specific images.

In addition to these measures, strict security-oriented changes are also applied to your wireless connectivity. The moment the mode is activated, your phone will refuse to connect to any unsecured or password-free public Wi-Fi networks; if you are already connected to such a network, the device will immediately disconnect from it. Furthermore, 2G and 3G cellular support are completely disabled to prevent attacks that exploit vulnerabilities in older, less secure networks.

No Device Has Ever Been Hacked While in This Mode
While this mode may alter the standard phone usage experience, it serves as the most formidable defense against spyware and hackers. Apple spokesperson Sarah O'Rourke stated, "To date, we have not received any reports of a spyware attack successfully compromising an Apple device while Lockdown Mode was enabled."

What Is Important for You?
Fulfilling its promise, Apple has begun sending alerts to users whose iOS software is outdated. If, for any reason, you are unable to update your device to the latest software, you can utilize this "Lockdown Mode" to ensure your security.

How Does It Stop Hackers?
Even Apple critic and cybersecurity expert Patrick Wardle acknowledges that Lockdown Mode makes the work of hackers extremely difficult and costly. Simply put, this feature reduces the iPhone's "attack surface"—the potential entry points through which malware can infiltrate the device. It blocks attachments received via messages and restricts certain features within the web browser. This effectively thwarts attacks—particularly "zero-click" exploits—in which a phone is compromised without the user ever having to click on a link.

Should You Use It?
While it is conceivable that a highly sophisticated hacking technique might exist that has gone undetected by Apple or security experts, the feature's track record to date has been exemplary. If you choose to enable this feature, you may experience only minor inconveniences—for instance, having to manually copy a link from a message and paste it into your browser. However, if you have even the slightest concern regarding your digital security, or if you believe you could be a potential target for cyberattacks, enabling Lockdown Mode is the most prudent course of action.
