Browser security

Security when surfing the internet is crucial in today's digitally connected world. With the increasing reliance on online services for everyday tasks, from banking to shopping to communication, the risk of cyber-attacks, data leaks and other security threats is also increasing. Browsers, as the gateway to the World Wide Web, play a central role in maintaining our digital security and privacy. Effective browser security therefore includes a range of measures and practices aimed at protecting personal data, ensuring the integrity of online transactions and minimizing the risk of malware and phishing attacks.

Here are 10 tips for surfing the web safely

Always keep your browser up to date. Browser updates often contain important security patches that close vulnerabilities that could be exploited by attackers.

  • Activate the Do-Not-Track function.
  • Deactivate JavaScript and Flash in the settings if they are not required, as they are often misused for malicious purposes.
  • Restrict cookies and access to location data.

Good antivirus software can detect and block many types of malware before they cause damage to your system.

  • Ad-Blocker: Block intrusive and potentially harmful advertising.
  • Script-Blocker: Block potentially harmful scripts.
  • HTTPS Everywhere: Make sure that websites use an encrypted connection if possible.
  • Privacy Badger or similar tools: Block trackers that track your surfing behavior.

Only install extensions from trusted developers and check the permissions they request. Too many extensions can not only impair the performance of your browser, but also pose a security risk.

A virtual private network (VPN) encrypts your data traffic and hides your IP address, which increases your privacy and security on the Internet. The VPN is all the more important when working on the move, see also our information page on secure mobile working.

Avoid downloading files or clicking on links from unknown or untrusted sources. These could contain malware or lead to phishing sites.

Use a different, strong password for each online service. A password manager can help you to store and manage these securely.

Wherever possible, you should enable two-factor authentication to ensure an extra level of security for your online accounts.

Many websites and services offer customizable privacy settings. Take the time to review and customize them to better protect your personal data.
