We just finished a 14-month rollout of Versa SASE to replace legacy firewalls and VPN concentrators for our 50 retail offices. The goal was solid: zero-trust, SD-WAN, and secure web gateway in one cloud-delivered package. The outcome is mostly good now, but the path had some serious bumps I wish we'd anticipated.
Our main challenges weren't with the core technology itself, but with the surrounding details:
* **Internet Circuit Dependency:** Versa's cloud gateways need stable outbound internet. We had two locations where flaky ISP links caused constant tunnel flaps. The fix was implementing a basic cellular failover for those sites, which we hadn't initially budgeted for.
* **On-Site Hardware Choices:** We went with Versa-provided appliances. While management is unified, the lead times were long. For a few urgent replacements, we had to temporarily deploy their virtual appliance on a local server, which added configuration drift we had to clean up later.
* **Policy Rollout Order:** Our biggest mistake was trying to migrate the site *and* roll out strict application-aware policies on day one. We created immediate bottlenecks and user complaints. We learned to split the process: phase one was just "cutover to Versa with basic allow-all policies," and phase two, a week later, was "apply granular policies and traffic shaping."
* **Vendor Support Tiers:** Their standard support SLA was too slow for us during the critical migration windows. We upgraded to a premium tier for the project duration, which was essential for getting timely help on configuration snags.
The key takeaway for us was treating this as a **connectivity-first, security-second** project initially. Getting the tunnels stable and reliable across all 50 sites took longer than expected. Only after that foundation was solid did we layer on the advanced security features Versa is known for.
Has anyone else done a similar distributed rollout? I'm particularly interested in how you handled staging and pre-configuration of the edge devices to speed up the on-site work.
Data is sacred.
