Meta’s WhatsApp messaging platform has launched a new Advanced Security Mode, offering users enhanced protection against potential hackers. With this move, WhatsApp joins a growing number of U.S.-based tech companies providing security-focused options, even if it means limiting certain features.

Starting Tuesday, the feature—named “Strict Account Settings”—will appear as a one-click toggle in WhatsApp’s settings. Once activated, multiple safety measures automatically come into effect to safeguard users from suspicious activity.

What Does the New Mode Do?

The advanced security mode includes:

• Blocking files from unknown numbers: Images, videos, and other attachments sent by unknown contacts will no longer automatically appear.

• Disabling link previews: URLs shared in chats will no longer show thumbnails, reducing the risk of malicious links.

• Silencing calls from unknown numbers: Incoming calls from unrecognized contacts will be automatically muted.

These steps have been identified by security experts as common avenues for hacking and phishing attempts.

Why WhatsApp Introduced the Feature

In a blog post, WhatsApp stated that while all user chats are protected by end-to-end encryption, some users—particularly journalists, public figures, and high-risk individuals—require additional safeguards against rare and sophisticated cyberattacks.

Meta joins other major tech companies offering advanced protection to high-risk users. For example:

• Apple’s Lockdown Mode (2022): Available on iPhone and macOS, this feature disables most message attachments and link previews, and restricts FaceTime calls and web browsing for users vulnerable to targeted attacks.

• Google’s Advanced Protection Mode: Focused on security-conscious Android users, it blocks potentially harmful apps from outside the Google Play Store and limits other device functionalities to reduce digital exposure.

Like these programs, WhatsApp’s new mode prioritizes security over certain conveniences, providing users with robust defenses against hacking attempts.

Expert Opinions

Cybersecurity researchers have welcomed WhatsApp’s announcement.

John Scott-Railton of Citizen Lab, University of Toronto, said the feature will particularly benefit activists, journalists, and users facing targeted threats. He also noted that WhatsApp’s move could encourage other tech companies to raise their security standards.

“Steps like these show that companies are taking digital safety seriously, and I hope more follow suit,” he said.

A Growing Trend in Tech

WhatsApp’s update reflects a broader trend in the technology industry: balancing user convenience with advanced digital security. While most users may not need these heightened protections, high-risk individuals increasingly require tools to guard against targeted cyber threats.

By making this mode optional, WhatsApp allows users to choose when and how they want extra protection, without compromising its core messaging experience for the majority of users.

Conclusion

The launch of WhatsApp’s Advanced Security Mode demonstrates how mainstream messaging platforms are evolving to meet the needs of high-risk users in an era of growing cyber threats. By blocking suspicious files, silencing unknown calls, and disabling link previews, WhatsApp aims to provide a safer and more secure messaging environment, setting a new standard for user protection in the industry.
