Each architecture offers a distinct approach to eliminating implicit trust and securing the modern enterprise.
Software-Defined Perimeter (SDP)
Replaces the traditional network perimeter with a dynamic, identity-centric boundary. All resources are invisible until authenticated and authorized.
Microsegmentation
Divides the data center into granular, isolated security segments down to individual orkloads, preventing lateral movement of threats.
Identity-Aware Proxy (IAP)
Routes all application access through an identity-aware reverse proxy that enforces per-request authentication and authorization.
NIST SP 800-207 Architecture
The foundational government standard defining zero trust tenets: continuous verification, least privilege, and assume-breach mentality.
SASE (Secure Access Service Edge)
Converges SD-WAN with cloud-delivered security (CASB, FWaaS, SWG, ZTNA) into a single cloud-native service.
Zero Trust Network Access (ZTNA)
Provides adaptive, identity- and context-based access to private applications without exposing them to the internet.
BeyondCorp Model
Google’s pioneering approach that shifts access controls from the network perimeter to individual devices and users regardless of location.
Zero Trust Data-Centric Security
Focuses protection on the data itself through classification, encryption, tokenization, and rights management rather than network location.
Service Mesh Zero Trust
Implements zero trust at the microservices layer using sidecar proxies for mutual TLS, RBAC, and observability between services.
Continuous Adaptive Risk & Trust (CARTA)
Gartner’s framework for continuously assessing risk and trust throughout every digital interaction, adapting access in real-time.
Cloudbrink delivers high-performance ZTNA with 30x faster access than legacy VPNs. See it in action.
