IPSec Connection
Definition
Oracle Cloud's secure VPN service that creates encrypted network tunnels over the internet, ensuring secure data transmission and privacy.
Use Cases
- Zoom: Securely connecting corporate offices and data centers to cloud environments for internal services and operations — Uses IPsec-based site-to-site VPN connectivity as part of a broader hybrid network approach to encrypt traffic over the internet between locations and cloud networks (Encrypted connectivity for hybrid access without requiring dedicated private circuits for every site, supporting secure operations and flexibility)
- Netflix: Secure connectivity between corporate networks and AWS environments for internal tooling and operational access — Uses AWS Site-to-Site VPN (IPsec tunnels) in scenarios where encrypted internet-based connectivity is appropriate, alongside other connectivity options (Improved security for network traffic in transit and faster provisioning compared to dedicated connectivity for certain use cases)
- Spotify: Hybrid connectivity between office networks and cloud resources used for engineering and business systems — Uses site-to-site VPN (IPsec) patterns to provide encrypted connectivity over the internet for selected network paths and environments (Secure access to cloud resources from corporate networks with reduced setup time versus private circuits for smaller sites or temporary needs)
Provider Equivalents
- AWS: AWS Site-to-Site VPN
- Azure: Azure VPN Gateway (Site-to-Site VPN)
- GCP: Cloud VPN
- OCI: IPSec VPN (IPSec Connection) via OCI VPN Connect
Frequently Asked Questions
- What's the difference between an IPSec Connection and FastConnect (or Direct Connect/ExpressRoute/Cloud Interconnect)?
- An IPSec Connection is an encrypted tunnel over the public internet. It’s usually quicker to set up and works anywhere you have internet access, but performance can vary with internet conditions. FastConnect (OCI) and similar services (AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect) use private connectivity through a provider/partner, typically offering more consistent latency and higher bandwidth, but they take longer to provision and usually cost more.
- When should I use an IPSec Connection?
- Use it when you need secure connectivity between on-premises (or another cloud) and OCI over the internet—especially for quick deployments, smaller bandwidth needs, branch offices, temporary environments, or as a backup path for a dedicated private circuit. If you need consistently high throughput and predictable latency, consider FastConnect instead (or use both: FastConnect as primary and IPSec as failover).
- How much does an IPSec Connection cost?
- Costs typically depend on (1) the cloud provider’s VPN pricing model (some charge per VPN connection/tunnel-hour, others may not charge for the VPN resource itself), (2) data transfer/egress charges from the cloud, and (3) any third-party costs for your customer-premises VPN device or firewall. In OCI, you should also factor in data egress and any required networking components; always confirm current pricing in the OCI pricing page for VPN Connect and data transfer.
