Independent Microsoft GSA security architects.
Architecture reviews, gap analysis, remediation reports and target-state design — for teams adopting Microsoft Entra Global Secure Access, or already running it and unsure it's architected right. Senior-led, delivered in weeks, not quarters.
Your VPN is a liability, not a strategy.
A legacy VPN gives anyone with a tunnel broad access to the whole network. Microsoft's answer — Global Secure Access — replaces that with per-app, identity-based Zero Trust: users authenticate to each app, and access follows identity, device posture and risk — not the network they're on.
But buying the license is only step one. Where GSA projects stall is deployment: app discovery, connector rollout, Conditional Access migration, and change management. That's the part we do every day.
Advisory and delivery across the Microsoft Entra SSE stack.
Independent architecture reviews, gap analysis and target-state design — plus hands-on delivery of Private Access and Internet Access. Senior-led, tailored to your apps, users and identity estate.
GSA Architecture Review & Health Check
Independent review of your existing deployment — Internet Access, Private Access, traffic forwarding and client — benchmarked against Microsoft best practices and Zero Trust alignment.
REVIEW · HEALTH CHECKGap Analysis & Remediation Reports
Detailed gap analysis with a prioritized remediation roadmap — risks, dependencies and improvement opportunities, documented and board-ready.
GAP ANALYSIS · REMEDIATIONTarget-State Architecture & Design
Secure internet and private access architecture, identity and device integration models, and decision documentation for your architecture review board.
TARGET-STATE · DESIGNEntra Private Access (ZTNA)
Replace your VPN. Publish on-premises and legacy apps — including TCP/UDP — with Quick Access and per-app adaptive access, no legacy tunnel required.
ZTNA · VPN REPLACEMENTEntra Internet Access (SWG)
Roll out an identity-based Secure Web Gateway — web content filtering, threat protection and conditional controls for internet, SaaS and Microsoft 365 traffic.
SWG · SECURE WEB GATEWAYConditional Access & Identity
Design and migrate the identity, device and Conditional Access model — Entra ID, Intune compliance and sign-in risk, across Windows 11 and Azure Virtual Desktop.
ENTRA SUITE · IDENTITYSecurity Monitoring & Operations
Telemetry, logging, Defender and Sentinel integration recommendations so your GSA estate stays observable, operable and audit-ready.

Right-size your Microsoft Entra Suite, Entra ID P1/P2 and GSA licensing so you pay for what you use — and unlock features you've already bought.

Ongoing operations — health checks, connector monitoring, policy changes and incident support — so your GSA estate stays secure after go-live.
ONGOING · SUPPORTSenior-led and personal. Not billable-hour theater.
Going direct to a mega-vendor means template playbooks, junior delivery teams and long queues. We're the alternative.
Built by a Global Secure Access SME
Led by a security professional with enterprise experience as a Global Secure Access subject-matter expert at a national telco — the person who designs your architecture is the one you talk to.
Faster turnaround
Small, focused, senior. No offshore handoffs, no 12-person project theatre. We scope in days and ship in weeks, with a real timeline you can hold us to.
Personalized to your environment
We learn your apps, users and constraints first, then design. Not a template where your business is forced into the product's box.
Fixed outcomes, clean handover
Clear deliverables, documented runbooks and knowledge transfer to your team — so you're never locked in and can operate GSA yourself.
A focused path from review to rollout.
Discovery, gap analysis and target-state design — then delivery, phased and low-risk.
Discover & Assess
Workshops and technical discovery — review your current GSA/VPN estate, identity and device posture, and Zero Trust alignment.
