Can you imagine a life without the internet? From our daily routines to the way we work, the internet has become an inseparable part of modern life. But so are the threats that come with it. As technology evolves, so do cyber threats. Now we are facing cyber threats and crimes powered by AI and automation, making attacks more sophisticated and malicious.
If you’re not practicing safe browsing in the internet world, you’re putting your identity, data, and devices at risk.
Back in 2021, Swiss Cyber Institute shared a blog article guiding on secure online behavior. Now, it’s time for an updated look. Here’s your updated guide on how to stay secure online, without giving up your digital freedom.
1. Keep your browser and extensions updated
Many cyberattacks exploit out-of-date browsers. Make sure automatic updates are enabled for your browser to stay protected against the latest threats. Also, review regularly and remove browser extensions that you no longer use.
2. Use privacy-first browser settings
Default settings are not enough. Customize your privacy settings.
- Chrome: Settings > Privacy and security > Enhanced protection
- Firefox: Privacy & Security > Strict
- Safari: Prevent cross-site tracking ON
Bonus: Use privacy-focused browsers like Brave or Firefox Focus for added protection.
3. Visit HTTPS websites
Whenever you’re browsing, check that the website URL starts with HTTPs, not just HTTP. The extra “S” stands for secure, meaning the data you send and receive is encrypted.
4. Avoid downloading files from untrusted sources
Even PDFs and Word files can carry malware. In fact, malware infections are projected to reach 6.5 billion globally in 2025. To stay safe, always verify the source of any file you download and scan it using a trusted cloud-based antivirus or tools like VirusTotal.
Every time you visit a website, small bits of data called cookies are stored in your browser. While some cookies like remembering your login or languages preference are useful, remember that it can track your behavior across website. These third-party cookies can be used to build detailed profiles about you, often without your knowledge or consent. To protect your privacy, make it a habit to clear cookies and track data regularly.
6. Use an ad blocker
Ads popping up on your screen could spread ransomware and spyware on your device. Implementing a reliable ad blocker is a crucial defense, preventing these malicious elements from even loading.
7. Use a password manager, not your browser
Storing your password on your browser feels easy and convenient. Unfortunately, it’s generally not the most secure practice. Browsers are more vulnerable to malware and attacks that could expose your saved credentials. Instead, use a secure password manager that supports biometric login and data breach monitoring.
8. Switch to privacy-respecting search engines
In 2025, search engines know more about you than your closest friend. Use options like DuckDuckGo, Startpage, Brave Search etc. They don’t track you or sell your data.
9. Use strong passwords + 2FA
Your password should be long, random, and unique. Yes, that makes it hard to remember. That’s why it brings us back to the number 7, using password manager. But even strong passwords are not enough. Wherever possible, enable two-factor-authentication (2FA), preferably app-based ones (like Google Authenticator, Microsoft Authenticator, Authy) over SMS-based methods. Why? Because SMS can be intercepted through SIM swapping or phishing attacks, authentication apps generate time-based codes that are more secure and harder to compromise.
10. Be careful with public Wi-Fi. Use a VPN.
Public Wi-Fi networks in aiports, hotels, and restaurants are convenient, but high-risk. Hackers can easily intercept unencrypted data, putting your passwords, personal info, and browsing activity at risk. If you have to use public Wi-Fi, use a VPN (Virtual Private Network). It encrypts your internet traffic and hides your IP address, making it nearly impossible for attackers on the same network to spy on your activities.
Final Thoughts
The internet is a powerful tool, but there are full of traps that threaten your privacy and security. The good news? You don’t have to be a cybersecurity expert to stay safe. Small habits make a big difference. Use these 10 tips to protect your devices, identity, and digital life.
When it comes to workplace cybersecurity, the needs vary by industry. That is why Swiss Cyber Institute offers tailored Team Training to support organizations build cyber resilience cultures and empower employees with practical, not complicated things they can implement on their tasks.
Stay informed and stay secure.
