In our connected world, where cyber threats are rising, protecting your online activities and private information is essential. People often use virtual private networks (VPNs) and firewalls to keep themselves safe and confidential online.
This article will help you decide whether you need a virtual private network (VPN), a firewall (FW), or both.
What is a VPN?
A Virtual Private Network, or VPN, creates a secure connection between your device and the internet. It encrypts your internet traffic, routing it through a remote server operated by the VPN provider. This encryption adds a layer of protection, making it difficult for malicious actors to intercept your data. VPNs also allow you to browse the internet anonymously by masking your IP address.
A Firewall acts as a barrier between your device and the internet. It monitors incoming and outgoing network traffic based on predefined security rules. Firewalls analyze data packets, filtering out potentially harmful ones and blocking unauthorized access to your system. They are primarily designed to prevent unauthorized access and protect your network from external threats.
