flexiWAN is an open-source SD-WAN and SASE solution for network routing and security. Its components divide the work between flexiManage for central management, flexiEdge for local routing and security, and flexiAgent for synchronization and monitoring. Supported networking includes IPSec over VxLAN tunnels, full-mesh, hub-and-spoke and partial-mesh topologies, application-based path selection, internet breakout, DHCP and static routes. Automation includes zero-touch provisioning, multi-WAN failover, tunnel load balancing and AI-based network healing. Firewall capabilities include application identification, port forwarding and 1:1 NAT, and the platform supports 2FA login. Its modular App Store supports third-party applications for security, WAN optimization, voice and video optimization, and DPI. Deployment options include Linux, web, API and self-hosted use, with cloud deployments and virtual appliances also listed. A free plan for 1–5 instances and a 30-day trial are available. The pricing page says minimum fees apply after the trial; paid pricing is listed from $33/mo (annual).

flexiWAN: the full review

flexiWAN combines network management, routing and security capabilities with cloud, virtual appliance and self-hosted deployment options. A trial and free tier are listed, but minimum fees apply after the trial period.

flexiWAN is an open-source SD-WAN and SASE platform for teams that need centralized control over routing and security across network edges. It is strongest for enterprise and service-provider deployments that value flexible topology and multi-WAN automation; the 10-site limit and fees after the trial may rule it out for broader rollouts.

Overview

Three components divide the work: flexiManage handles centralized management, flexiEdge provides local routing and security, and flexiAgent synchronizes and monitors. That architecture gives distributed deployments a central management point while retaining routing and security at each edge. Its hybrid deployment model suits teams that want options across cloud, virtual appliances, and self-hosting.

The SaaS model targets enterprises and smaller service-provider deployments, while the service-provider model is typically used by service providers and system integrators. The stated limit of 10 sites is a serious planning constraint: it sits uneasily beside paid tiers covering thousands of flexiEdge instances, so organizations should confirm that their intended rollout fits both measures.

Key features

Routing and resilience

IPSec over VxLAN tunnels and full-mesh, hub-and-spoke, and partial-mesh topologies give network teams several ways to connect sites. Application-based path selection and internet breakout help direct traffic, while DHCP and static routes cover core addressing and routing needs. Zero-touch provisioning, automatic multi-WAN failover, load balancing across tunnels, and AI-based network healing aim to reduce routine deployment and recovery work. These capabilities are most useful where multiple WAN links and distributed edges make manual operations costly.

Security and extensibility

Firewall controls include application identification, port forwarding, and 1:1 NAT, with two-factor login for account access. The modular App Store adds third-party applications for security, WAN optimization, voice and video optimization, and deep packet inspection. That breadth is valuable when teams want to extend a common edge platform, though the specific applications they need should guide the decision. flexiWAN publishes its source code for security review and directs vulnerability reports to [email protected]; it does not offer a bounty program.

Deployment and APIs

Cloud and VPS options include Google Cloud Platform, AWS EC2, Oracle Cloud, Hetzner Cloud, and DigitalOcean. Pre-built virtual appliances support VMware, KVM/QEMU/Proxmox, and VirtualBox, alongside Linux, web, API, and self-hosted platforms. The feature roadmap includes a northbound REST API with access keys and flexiEdge-side APIs and UI, which may suit teams planning programmatic management, but API needs should be checked against the capabilities they require.

Pricing

flexiWAN offers a free tier for 1–5 flexiEdge instances and a 30-day trial. Support is provided during the trial, with installation and configuration assistance as required. Minimum fees apply after the trial, and only one account and trial period is allowed per person, company, or organization. The published instance tiers are billed per instance per month, including yearly-billed options:

InstancesPaid yearlyPaid monthly
1–1033.00 USD per year40.00 USD per month
11–10025.00 USD per year30.00 USD per month
101–50021.00 USD per year25.00 USD per month
501–1,00017.00 USD per year20.00 USD per month
1,001–5,000—12.00 USD per month

The yearly tiers lower the per-instance monthly rate relative to their monthly counterparts, making them a better fit for deployments willing to commit on that billing basis. The entry tier starts at 1–10 instances; the free 1–5 tier is useful for a small evaluation, but minimum fees after the trial mean it should not be mistaken for an ongoing no-cost deployment. Monthly pricing is available through 1,001–5,000 instances, while no yearly rate is shown for that largest band.

Platforms

flexiWAN supports web, API, Linux, and self-hosted use, with cloud/VPS deployments and virtual appliances for VMware, KVM/QEMU/Proxmox, and VirtualBox. The range suits organizations choosing between managed cloud infrastructure and running appliances in their own environment.

Who it's for

Choose flexiWAN if you manage multiple edge locations, need application-aware routing or multi-WAN resilience, and can work within the 10-site limit and post-trial minimum fees. Enterprises and smaller service providers are the stated SaaS audience; service providers and system integrators are the typical service-provider-model users. It is less compelling for a rollout that must exceed the site limit or for anyone seeking a free service beyond the trial.

Pros and cons

  • Pro: Multiple topology choices, application-based path selection, failover, and tunnel load balancing address varied multi-site routing needs.
  • Pro: Cloud, virtual appliance, and self-hosted deployment options support different infrastructure preferences.
  • Pro: Firewall controls and a modular App Store bring security and optimization options into the same platform.
  • Con: The 10-site limit can constrain organizations planning wider deployment, despite instance tiers reaching thousands.
  • Con: Minimum fees apply after the trial, and the one-trial-per-organization rule limits repeated evaluation.
  • Con: The feature roadmap places the northbound REST API and edge APIs/UI on the roadmap rather than presenting them as established capabilities.

Alternatives

For a broader comparison, browse SD-WAN Software.

  • Cloudflare Access is the better fit when access management for a smaller user base matters more than SD-WAN: its free plan covers under 50 users, with paid pricing at 7.00 USD per month.
  • Arista NG Firewall is worth considering when basic security and connectivity are the priority and a free plan with limited capabilities is sufficient.
  • D-Link Nuclias Cloud SD-WAN Gateway (DBG-2000) may suit buyers seeking a free-plan gateway license, with one-year and three-year license options priced at 111.99 USD per year and 278.99 USD per year respectively.
  • AccessOne is another paid option for teams needing support across web, desktop, and mobile platforms.
  • Versa Zero Trust Network Access is a paid alternative with Essential and Professional plans, including a 10-application Essential tier.
  • Cato Client is a paid option with a free trial and a commercial license purchased from Cato for one or more years.
  • ExtremeControl is another paid option for organizations seeking a platform that supports API, web, desktop, and self-hosted environments.
  • Fortinet Secure SD-WAN may appeal to FortiGate users seeking basic SD-WAN functionality included on FortiGate models without an additional charge.

Verdict

flexiWAN is a strong candidate for enterprises and smaller service providers that need flexible edge routing, multi-WAN automation, and deployment choice in one SD-WAN/SASE platform. Its main advantage is the combination of topology options, resilience features, and cloud or self-hosted appliances; its main reason to look elsewhere is the 10-site limit alongside minimum fees after the trial. Confirm the site constraint and ongoing cost fit before committing.
