Cybersecurity tools: The roles of antivirus and VPNs

Cybersecurity requires a multi-layered approach combining different tools to protect both devices and internet connections. Antivirus software acts as a protector for hardware, such as computers and mobile phones, by scanning, detecting, and removing malicious software like viruses and ransomware. These programs work in the background, updating databases to recognize new threats in real time and often include features like firewalls and phishing protection.

While antivirus software is highly effective at specialized malware detection, it is often complemented by a Virtual Private Network (VPN). While an antivirus protects the device itself, a VPN secures the connection path, helping to prevent data theft and credential interception when using public internet connections.
