We’re a small team of five Python engineers running our workloads on Kubernetes, mostly in AWS. Lately, we’ve been tightening up security and access controls, and I’ve been looking at Cloudflare One’s Zero Trust Network Access (ZTNA) offering as a potential solution.
Our main needs are:
- Secure, identity-based access to internal K8s services and management dashboards (like Argo CD or a custom admin panel) without exposing them to the public internet.
- Something that integrates cleanly with our existing OIDC provider (we use Google Workspace).
- Minimal ongoing configuration overhead for a team our size — we don’t have a dedicated security or infra person.
I’ve read the docs and spun up a trial, but I’m keen to hear from other small engineering shops. How has it worked in practice for securing Kubernetes environments? Any particular pain points or “aha” moments during setup? For example, did you use the Cloudflare Tunnel agent in-cluster, or run it elsewhere? How’s the experience with short-lived certificates and service authentication?
Also, if you compared it to other ZTNA tools (like Twingate or Tailscale) before choosing Cloudflare, I’d be curious what tipped the scales.

Keep it constructive.
I'm Hannah, I manage procurement and SaaS spend for a 40-person fintech where we run a dozen microservices on GKE. We deployed Cloudflare Zero Trust two years ago to replace a VPN for access to our staging environment and internal tooling.
**Core comparison from our bake-off (Cloudflare vs. Twingate vs. Tailscale):**
- **Team Size Fit:** Cloudflare and Twingate are built for scale. Their admin dashboards have enterprise concepts (locations, device posture) you'll ignore. For exactly five people, Tailscale's "just works" model is a cleaner fit. Twingate felt overly complex for under 50 users.
- **Real Pricing & Commitment:** Cloudflare's Zero Trust starts at $7/user/month billed annually, but you must buy at least 5 seats. That's $420/year minimum. Twingate is free for under 50 users but only for one "remote network" (your K8s cluster). Tailscale is free for 3 users, then $12/user/month for teams. The hidden cost is Cloudflare's tunnel compute if you bypass their proxy; egress adds up.
- **K8s Integration Effort:** Cloudflare Tunnel (cloudflared) runs as a DaemonSet. It took us about 4 hours to get it routing traffic correctly to our Argo CD and internal APIs. The main gotcha was configuring hostname-based routing in the tunnel config when you have multiple services. Twingate's connector was simpler but required more manual service definitions.
- **Where Cloudflare Clearly Wins:** If you foresee needing DDoS protection, a WAF, or bot management for those same internal dashboards later, having it all in one dashboard is powerful. Their integration with Google OIDC required about 7 clicks and worked on the first try. Short-lived certs for service auth are handled automatically by the tunnel; you don't touch them.
I'd recommend Tailscale for your specific case of five engineers wanting dead-simple, secure access. It's essentially a distributed WireGuard mesh with an OIDC button. If you know you'll stay tiny and just need secure shell/HTTP access to pods and dashboards, it's the fastest path. If you can confirm you'll need layer 7 security policies (like country blocking for your admin panel) or are definitely adopting more Cloudflare services soon, then choose Cloudflare. Tell us which matters more: simplest setup or future feature consolidation.
