What is a VPN?
A Virtual Private Network (VPN) is a technology that enables a secure and encrypted connection over less secure networks, such as the Internet. Your data traffic is routed through a secured tunnel, hiding your IP address and protecting your online identity.
A VPN is primarily used to enhance privacy and security on the Internet. It creates a secure connection between your device and the Internet by encrypting your data, thereby thwarting eavesdropping attempts.
How does a VPN work?
Encryption
Your data traffic is encrypted so that malicious actors, Internet service providers, or hackers cannot see it. This encryption is achieved through protocols such as OpenVPN, L2TP/IPsec, and IKEv2/IPsec.
IP Address Masking
A VPN hides your real IP address and assigns you a new IP address of a VPN server. This helps to protect your identity and bypass regional Internet restrictions.
Benefits of a VPN
Enhanced Security
A VPN provides an extra layer of security by encrypting data traffic and denying unauthorized access. It protects you from cyber attacks, especially when using public Wi-Fi networks.
Privacy and Anonymity
By masking your IP address and using the encrypted tunnel, your online activity is anonymized. Your Internet provider cannot track your activities, and your sensitive data remains secure.
Access to Restricted Content
With a VPN, you can access content that is blocked in your country or by your network due to geographic or institutional restrictions. This includes streaming services, websites, and apps blocked in certain regions.
Avoidance of Data Surveillance
A VPN can prevent monitoring by your Internet provider or government agencies, thereby protecting your personal data and browsing behavior.
Use Cases for VPNs
Securing Public Wi-Fi
Public Wi-Fi networks are susceptible to cyber attacks. When you connect with a VPN, your data traffic is encrypted regardless of the type of network, allowing you to surf securely.
Remote Work
VPNs allow employees to securely access corporate networks, regardless of their location. This is especially crucial in today's remote work environment.
Protection Against Internet Censorship
In some countries, there are strict Internet censorships. A VPN can help bypass such barriers and enable access to an unobstructed Internet.
Important Considerations When Selecting a VPN
Protocol Types
A good VPN should offer various protocols that ensure flexibility and security. Preferred protocols are OpenVPN, IKEv2/IPsec, and WireGuard.
No Logging Policy
Ensure that the VPN provider does not store logs of your activities to guarantee your privacy.
Speed and Bandwidth
A VPN should not significantly impact your Internet speed. Look for providers known for their fast connections and unlimited bandwidth.
Number of Server Locations
More server locations provide better options to bypass geo-restrictions and achieve optimal connection speeds.
Conclusion
A VPN is an essential tool for protecting one’s online privacy and improving Internet security. It offers a secure and encrypted connection, increases anonymity, and allows access to content without restrictions. As cyber threats continue to rise, both individuals and businesses should use a VPN service to secure their digital activities.

VPN in Germany: Current Developments
The importance of VPNs in Germany is continuously increasing. According to recent studies by the Federal Office for Information Security (BSI), German companies are increasingly affected by cyber threats. The Bitkom Association reports that 84% of German companies were victims of cyber attacks in the last two years.
Particularly in the area of VPNs, the following trends are apparent:
Increased investments in preventive security measures
Heightened awareness of holistic security concepts
Integration of VPN into existing compliance frameworks
EU Compliance and VPN
With the introduction of the NIS2 Directive and stricter GDPR requirements, German companies must adapt their security strategies. VPN plays a central role in meeting regulatory requirements.
Important compliance aspects:
Documentation of security measures
Regular review and updating
Proof of effectiveness to supervisory authorities
Practical Implementation in Corporate Daily Life
The integration of VPN into corporate daily life requires a structured approach. Experience shows that companies benefit from a phased implementation that considers both technical and organizational aspects.
Think of VPN like insurance for your company: The better you are prepared, the lower the risk of damage from security incidents.
Further Security Measures
For a comprehensive security strategy, you should combine VPN with other security measures:
Vulnerability Management - Systematic vulnerability management
Penetration Testing - Comprehensive security testing
Security Hardening - Employee awareness
Incident Response Plan - Preparation for security incidents
Conclusion and Next Steps
VPN is a vital component of modern cybersecurity. Investing in professional VPN measures will pay off in the long term through increased security and compliance alignment.
