The Importance of Network Security
- Network security is crucial in protecting sensitive data, preventing unauthorized access, and maintaining business continuity.
- A robust network security infrastructure ensures the confidentiality, integrity, and availability of information.
- Network security breaches can lead to financial loss, reputational damage, and legal repercussions.
- Breaches may result in data theft, disruption of services, and compromised customer trust.
Why do you need network security for your organization
