Software-Defined Perimeter
Secure access without exposing the network.
Software-Defined Perimeter (SDP) replaces legacy VPN infrastructure with a cloud-delivered, identity-centric access model that connects users directly to the applications they need — never to the network. Acentria's SDP/ZTNA solution eliminates lateral movement risk, reduces attack surface by over 90%, and delivers a user experience that is faster and more reliable than traditional remote access.

Solution Overview
Software-Defined Perimeter
Legacy VPN solutions were designed for a world where employees worked from fixed offices on corporate-managed devices. Today's distributed workforce demands access from any device, any location, at any time — and traditional VPNs respond by granting broad network access that places sensitive data and critical systems at risk. Acentria's Software-Defined Perimeter replaces this model with a zero-trust network access (ZTNA) architecture where the network is never directly exposed — only specific applications are reachable, and only after identity and device posture are verified.
Our SDP implementation leverages a cloud-delivered broker model: users connect to the nearest point-of-presence (PoP), are authenticated and authorised, and receive an encrypted micro-tunnel to the specific application resource — not to the underlying network segment. This eliminates the ability of attackers who compromise a user's device to scan the corporate network, move laterally, or reach systems the user was never authorised to access. All sessions are logged, inspected, and correlated with identity and threat intelligence.
The business outcomes are substantial: organisations report a 60% reduction in remote access infrastructure costs through VPN consolidation, a near-elimination of network scanning and lateral movement incidents from compromised remote endpoints, and a significant improvement in user experience through intelligent routing that connects users to the fastest available application gateway. Our cloud-delivered model requires no on-premises hardware and deploys in weeks.

Core Capabilities
How We Deliver Software-Defined Perimeter
Cloud-Delivered ZTNA Broker
A globally distributed cloud broker authenticates users and devices before establishing encrypted micro-tunnels to specific applications — the network remains completely invisible.
Identity & Device-Aware Access
Every connection is conditioned on verified user identity, device compliance posture, and real-time risk signals — with step-up authentication for high-sensitivity applications.
Dynamic Port & IP Concealment
Application infrastructure is protected behind the SDP controller using single-packet authorisation — no ports are open and no IP addresses are discoverable until access is explicitly granted.
Intelligent Traffic Optimisation
Traffic is intelligently routed through the nearest PoP with direct-to-cloud paths for SaaS applications, delivering lower latency than legacy VPN backhauling.
Multi-Cloud & Hybrid Connectivity
Connect users to applications hosted anywhere — AWS, Azure, GCP, on-premises data centres, or co-location facilities — with a consistent policy model across all environments.
VPN Migration & Consolidation
Structured migration services replace legacy VPN concentrators with SDP, eliminating hardware refresh cycles, reducing licensing costs, and improving scalability.
Our Approach
How It Works
Application Discovery & Dependency Mapping
We catalogue all remote-accessed applications, their hosting environments, and their user populations to design accurate access policies before any infrastructure change.
SDP Controller & Connector Deployment
SDP connectors are deployed in front of each protected application — on-premises or cloud — while the cloud controller is configured with identity provider integration and device compliance policies.
User Onboarding & VPN Cutover
Users are migrated to the SDP client in cohorts with parallel-run periods. Legacy VPN access is progressively decommissioned as SDP coverage is validated.
Continuous Access Analytics & Policy Refinement
Session telemetry feeds into analytics dashboards for anomaly detection, access pattern review, and policy tightening based on observed usage and emerging threats.
