Cloud-delivered ZTNA brokers the connection to your application through the vendor's global cloud. Coelion is a sovereign application gateway, running on your own server. Both remove the network a VPN exposes, but with Coelion no vendor is in the trust path and your access decisions never leave your infrastructure. Coelion removes the vendor-operated broker and the foreign-jurisdiction control plane when the workload runs on web applications and the priority is sovereignty.
A cloud ZTNA data plane can be vendor-hosted or run on customer infrastructure, but the policy and brokering control plane is vendor-managed SaaS. Coelion has no separate control plane: policy, authentication, request resolution, and audit are the same on-premises process, and no vendor can be compelled, breached, or mis-scoped into a path it is not in.
Cloud ZTNA and Coelion converge on lateral-movement containment. They diverge on whether a vendor-operated cloud is a structural part of the access decision, on control-plane jurisdiction, and on whether the audit originates in a vendor cloud or on the customer's own server.
Arbitrary-protocol private access, global edge performance, a full SSE platform, a deep device-posture ecosystem, an existing high-assurance accreditation base, and scale tooling for thousands of segmented private apps. For a pure ZTNA conversation, Coelion is not the answer; for a browser-first workspace where the priority is sovereignty and no vendor in the access path, Coelion is the stronger posture.
