Our team is currently architecting a new SASE deployment, with a primary requirement being a robust, cloud-native SWG and CASB. The usual shortlist includes Zscaler, Netskope, and Cato Networks. However, we have specific operational constraints that make us want to evaluate alternatives outside of these three.
We require strong API-driven automation for policy-as-code and integration into our existing CI/CD pipelines for infrastructure deployment. Our environment is multi-cloud (AWS & Azure) with a significant containerized workload (Kubernetes). The solution must natively support zero-trust network access (ZTNA) for private app access without requiring a full tunnel VPN.
I'm looking for concrete experiences with platforms such as:
* **Palo Alto Networks Prisma SASE** (specifically their cloud-delivered SWG and ZTNA components)
* **Fortinet FortiSASE**
* **Cloudflare One** (their Zero Trust platform)
* Any other notable cloud-native contenders.
Key evaluation criteria:
* The ability to define security policies via declarative configuration (Terraform, API, etc.).
* Latency impact for global user populations.
* Integration complexity with existing IdP (Okta) and endpoint management (Intune).
* Real-world migration challenges from a traditional proxy or VPN setup.
Has anyone conducted a rigorous PoC comparing these to the established leaders? Particularly interested in the operational overhead of managing policies and any unforeseen bottlenecks in traffic inspection for SaaS applications.

>ability to define security policies via declarative configuration (Terraform, API, etc.)
I've been testing Cloudflare One's Terraform provider for a side project, and it's pretty solid for this. You can manage access policies and gateway rules as code. The API docs are good too. Latency was my big worry, but their network is huge so maybe it's fine? Anyone have real world latency numbers for users in Asia-Pacific vs, say, Zscaler?
FortiSASE might be a pain for policy-as-code last I checked, their API felt more bolt-on.
Thanks for sharing your experience with the Cloudflare One Terraform provider. The API-first approach is a big deal for us, too, so it's good to hear their docs are solid.
Your point about latency is a good one. I haven't seen direct head-to-head numbers for APAC, but a colleague mentioned they saw a noticeable improvement in initial connection times with Cloudflare in Southeast Asia compared to their old setup, which wasn't Zscaler though. I'd also be keen to hear if anyone has concrete performance comparisons.
>their API felt more bolt-on
I completely agree on FortiSASE from what I've seen. It doesn't feel native, which adds a lot of complexity for automation. Have you run into any specific limitations with Cloudflare's API when it comes to managing ZTNA rules, or has it been smooth?
Great discussion on the API experience, because that's often where the rubber meets the road. On the point about Cloudflare's API for ZTNA, I've found the core rule management for private app access via Access Groups and Gateway policies to be very consistent. The real nuance, and where you might hit a slight edge, is in the lifecycle management of the service tokens for your applications. It's API-driven, yes, but you'll need a clean pattern for rotating and distributing those tokens to your app hosts, which is more of an operational consideration than an API limitation.
On the APAC latency question, I don't have head-to-head Zscaler numbers either, but I can offer a data point. A deployment I worked on for a team with developers in Singapore and Tokyo saw a significant reduction in TLS handshake and initial byte times with Cloudflare One versus their previous direct-to-app-over-VPN model. The sheer density of their locations in those regions seems to pay off. The performance win came more from that than raw throughput. For a true comparison, you'd really need to run a PoC with your own traffic patterns from those user bases.
