Key differences between Network Security & Cyber Security
Understanding the differences between network security and cyber security helps businesses protect their systems effectively. While network security focuses on safeguarding your internal networks, firewalls, and connectivity, cyber security covers a broader scope including user devices, cloud applications, and protection against malware, phishing, and data breaches.

|---|---|---|
