Choosing the right VPN setup starts with understanding your goals and context. Different scenarios call for different technologies and priorities. Below are the main use cases, explained in practical terms — what you’re trying to achieve, what really matters, which tools fit, and who typically faces each challenge.

Allow employees or contractors to securely connect to company systems from anywhere — home, travel, or customer sites — as if they were in the internal office network.

Example: Engineers accessing Kubernetes dashboards, developers connecting to AWS, or finance staff logging into on-prem ERP systems.

• Ease of onboarding: Non-technical users should connect with minimal setup. Managed tools like AWS Client VPN or Tailscale reduce IT workload.

• Identity-based access: Integrate with SSO (Google Workspace, Azure AD, Okta) to simplify access control and quick revocation.

• Cross-platform support: VPN clients should work across operating systems and mobile devices.

• Performance and stability: Smooth SSH, video conferencing, and data transfers depend on reliable tunnels.

• AWS Client VPN with IAM or SAML authentication.

• Tailscale for quick setup and company-wide identity-based access.

• StrongSwan IKEv2 or OpenVPN for self-hosted remote access.

Distributed engineering teams, contractors, customer support, or administrative staff accessing sensitive internal apps.

Provide a continuous, private tunnel between an on-premise network and a cloud environment. Common when hybrid workloads exist or during migrations.

Example: A financial firm linking its datacenter firewalls to an AWS VPC for secure transaction processing.

• High availability: Needs redundant tunnels or failover paths to avoid downtime.

• Routing integration: Seamless traffic between cloud and on-prem subnets; static routes can cause issues.

• Encryption reliability: IPsec ensures compliance and standard compatibility across vendors.

• Operational visibility: Metrics and logs help diagnose latency or connection loss.

• StrongSwan or Libreswan on-prem ↔ AWS Site-to-Site VPN.

• Azure VPN Gateway ↔ pfSense / OPNsense.

• Cisco ASA ↔ GCP Cloud VPN.

Enterprises with hybrid setups, regulated industries (finance, healthcare), or companies gradually moving workloads to the cloud.

Connect multiple VPCs, regions, or clouds securely to enable data replication, service-to-service calls, or failover setups.

Example: A SaaS platform running in AWS EU-West communicating with its analytics and AI stack hosted in GCP.

• Performance: Cross-region latency directly affects application response times.

• Automation: Tunnel creation and route updates should be handled via Terraform or orchestration.

• Scalability: Easy to add new regions or clouds without downtime.

• Resilience: Redundant tunnels and gateways protect against single points of failure.

• WireGuard tunnels between AWS and GCP instances for speed and simplicity.

• AWS Transit Gateway VPN Attachments for large-scale routing.

• Netmaker or Netbird to automate WireGuard mesh between multiple cloud networks.

Multi-region SaaS products, cross-cloud architectures, global companies with region-specific infrastructure.

Allow developers, servers, and CI/CD pipelines to connect automatically without manual key exchange. Ideal for development, testing, and internal collaboration.

Example: A development team where laptops, Kubernetes clusters, and CI runners automatically connect via Tailscale for debugging.

• Automation: Developers shouldn’t manage keys or IPs manually.

• NAT traversal: Must work across home routers, corporate firewalls, and cloud providers.

• Access management: Central rules and ACLs prevent overexposure.

• Visibility: Admin dashboard for tracking connected peers.

• Tailscale with company SSO and ACLs.

• Headscale for a self-hosted Tailscale alternative.

• Netmaker for full control and large-scale orchestration.

Engineering teams, startups, and DevOps groups managing multi-environment or multi-cloud infrastructure.

Encrypt communication between systems (servers, services, databases) that interact across networks. Ensures that replication, messaging, or API calls stay private and tamper-proof.

Example: Application servers in AWS calling a PostgreSQL database in another region, or IoT gateways uploading data to cloud APIs.

• Lightweight and automated setup: Should integrate into infrastructure provisioning.

• Performance: Minimal latency for API or message processing.

• Short-lived credentials: Prevent long-term key leakage.

• Isolation: Each connection is sandboxed to reduce risk of lateral movement.

• WireGuard tunnels between microservices or EC2 instances.

• StrongSwan IPsec for regulated or older environments.

• Tailscale ACLs for dynamic service-to-service control.

Microservice-based applications, IoT infrastructures, data pipelines, and distributed backend systems.

Offer external vendors or partners secure and restricted access to specific resources — without exposing internal systems or networks.

Example: A marketing agency accessing analytics dashboards, or an external auditor connecting to specific databases.

• Granular permissions: Partners should see only assigned systems.

• Logging and traceability: Every login and action must be auditable.

• Ease of onboarding: External users shouldn’t require complex configuration.

• Quick revocation: Access should expire automatically when no longer needed.

• Tailscale ACLs granting per-user access to defined resources.

• AWS Client VPN with SSO group-based permissions.

• Cloudflare Access for browser-based, zero-trust access without network tunneling.

Organizations collaborating with agencies, vendors, or auditors, often under strict compliance requirements.

Provide secure, identity-aware access to internal web applications without exposing the entire network. Ideal for replacing traditional VPNs with simpler, browser-based authentication.

Example: Employees reaching internal admin dashboards or GitLab through Cloudflare Access or Twingate instead of joining a VPN.

• App-specific control: Access limited to approved web apps.

• Identity integration: Works with company logins and MFA.

• No VPN setup: Reduces support overhead and user friction.

• Visibility and compliance: Detailed access logs and policy enforcement.

• Cloudflare Access + Cloudflare Tunnel for secure web app access.

• Twingate, Perimeter81, or Zscaler for managed zero-trust solutions.

Remote-first companies, compliance-driven industries, or organizations modernizing access management and reducing VPN complexity.

Quickly establish short-term secure tunnels for temporary tasks like testing, troubleshooting, or migrations. Connections should disappear automatically once done.

Example: A DevOps engineer spinning up a WireGuard tunnel in a CI/CD job to connect to a test environment during deployment.

• Speed of setup: Must take seconds, not hours.

• Automation: Tunnels should be scriptable in pipelines or tooling.

• Ephemeral credentials: Avoid leaving residual access open.

• Low maintenance: Designed for temporary, one-time use.

• WireGuard for quick peer-to-peer setup.

• Tailscale ephemeral keys for CI/CD or temporary access.

• OpenVPN Docker containers for ad-hoc connectivity.

Infrastructure engineers, migration teams, and developers running automated tests or temporary environments.

Each scenario represents a distinct connectivity goal — from remote work to multi-cloud orchestration. The right VPN or zero-trust setup depends on how dynamic your environment is, who needs access, and how much management effort you want to invest.
