First, let’s explore the practical applications and advantages of deploying IPSec over SD-WAN.
1. Branch Office Connectivity
- Secure branch-to-branch communication: Securely connects branch offices to each other and to the headquarter using IPSec tunnels over SD-WAN, IPSec provides encrypted and reliable communication.
- High availability: Multiple ISP links (WAN) will ensure high availability and failover capabilities for critical branch office applications.
2. Remote Workforce
- Secure remote access: Employees can have secure access to their office network from home or remote locations, the connections are encrypted to corporate resources.
- Performance optimization: SD-WAN optimizes the network by routing traffic across the most effective paths
3. Cloud Connectivity
- Secure cloud access: Connectivity to the cloud is secure using IPSec tunnels with data encryption and security being its key features
- Hybrid cloud environment: SD-WAN can manage traffic between on-premise data centers and multiple cloud environments, providing reliable and secure data transfer.
4. IoT and Edge Devices
- Secure IoT communications: Data is transmitted securely from IoT devices through IPSec tunnels, protecting sensitive data.
- Edge computing: SD-WAN and IPSec facilitate data transfer to edge computing sites, ensuring proper handling of data with secure transfer.
