AppGate, a leader in Zero Trust Network Access (ZTNA) solutions, today announced that GigaOm has placed AppGate ZTNA in the “Leader” ring with an “Outpacing” velocity rating in the GigaOm Radar: Zero Trust Network Access Report, published Sept. 8, 2026. In its assessment, GigaOm wrote, “AppGate’s strength is the integrity of the access architecture, and no other product in this research matches it.”
GigaOm evaluated each vendor against 28 analyst-authored decision criteria, scoring each one on a 0 to 5 rubric based on published, verifiable evidence. AppGate ZTNA received scores of 5.0 for Zero Trust Architecture Integrity, Policy Engine Architecture and VPN Migration Tooling. It also scored 4.5 for Single Packet Authorization and 4.5 for Automation and Orchestration API. According to the report, the leader designation recognizes offerings that combine “broad feature depth, production-grade engineering, and sufficient operational documentation and ecosystem integration to be referenceable at scale.” The Outpacing rating reflects the pace at which a vendor ships category-moving capability.
GigaOm’s report describes AppGate ZTNA as “an architecturally orthodox software-defined perimeter and a deliberate pure-play.” The report notes that the AppGate ZTNA Controller “is a genuine policy decision point distinct from the Gateways that enforce.” It adds that per-session microfirewalls are built from signed entitlement tokens and that every component is fronted by single packet authorization, “so nothing accepts an unauthenticated connection.” GigaOm also cites the AppGate ZTNA Common Criteria Security Target and a reference build at the National Institute of Standards and Technology’s National Cybersecurity Center of Excellence as corroborating the design.
For VPN replacement, GigaOm’s report states, “Organizations replacing a VPN estate get the most here.” AppGate ZTNA analyzes observed Gateway traffic and presents hostnames and user counts for administrator review before they become entitlements. AppGate ZTNA then re-evaluates access conditions on events or on a set cycle, and it uses risk-tier claims to gate entitlement actions and trigger step-up interactions. Platform teams can manage access policy as code through a header-versioned REST API, a public OpenAPI specification and a vendor-maintained Terraform provider. GigaOm credits AppGate with “an infrastructure-as-code surface that outbuilds vendors many times its size.”
“Organizations moving beyond VPNs are choosing more than an access product,” said Leo Taddeo, CEO at AppGate. “They are choosing who controls the path to their most critical applications. AppGate ZTNA’s direct-routed architecture keeps private application traffic under the customer’s control, without rerouting connections through a vendor-hosted cloud. For enterprises and government agencies that value architecture built for control and data sovereignty, AppGate is the clear choice. GigaOm’s 5.0 score for Zero Trust Architecture Integrity reinforces the strength of that design.”
