Zero Trust Network Implementation
Replace your perimeter-and-VPN architecture with identity-based access. Every connection authenticated, every flow authorised, every session logged. We design the model, pilot it, and roll it out site-by-site without breaking anyone’s ability to do their job.
What’s Included
Identity-Based Access Design
Network access keyed to identity and device posture, not IP address. Integrates with Entra ID, Okta, or Google Workspace as your primary authority.
Microsegmentation
Application-level segmentation between workloads. Lateral movement after a breach is contained to a single tier — not free reign across the LAN.
ZTNA Replaces Legacy VPN
Cloudflare Access, Tailscale, Twingate, Zscaler ZPA, or Netskope — we recommend per use case. Users authenticate per-application, not per-network.
Policy-as-Code
Access policies versioned in Git, peer-reviewed, automatically deployed. Changes auditable, rollbacks one revert away.
Continuous Verification
Device posture (patched, encrypted, EDR-enrolled) re-checked on every session. Stale or non-compliant devices lose access automatically.
Phased Migration Plan
Most clients can't cut over overnight. We design a phased migration: easy wins first (SaaS apps via ZTNA), then internal apps, finally legacy systems.

Frequently Asked Questions
What does Zero Trust actually mean in network terms?
Zero Trust replaces "trusted internal network" with "every request authenticated, every flow authorised, every session logged." In practice that means: identity-based access (not IP), microsegmentation between apps, ZTNA replacing VPN, continuous device-posture checks, and policy-as-code. NCSC Zero Trust Architecture Design Principles is the UK reference framework we align to.
Can we adopt Zero Trust without ripping out our existing kit?
Yes — that's the whole point of a phased migration. We typically start by replacing remote-access VPN with ZTNA (a fast win), then segment SaaS, then internal apps, then legacy. Existing firewalls become enforcement points for microsegmentation rather than perimeter guardians. Expect a 6–12 month journey for a mid-sized organisation, not a weekend rip-and-replace.
Which ZTNA platform should we use?
Depends on what identity you run and which apps you need to expose. Cloudflare Access pairs well with Cloudflare-hosted infra and works for any web app. Tailscale and Twingate are excellent for IT teams that want fast deployment. Zscaler ZPA and Netskope are stronger for large enterprises with broad app portfolios. We'll recommend based on your specifics — usually with a small pilot before commitment.
Is Zero Trust just a marketing label?
The marketing has been heavy, but the underlying shift is real and necessary: perimeter security broke when work went remote, SaaS replaced on-prem, and breaches went lateral. Zero Trust is the umbrella term for the actual technical fixes — identity-based access, microsegmentation, continuous verification. We focus on the engineering, not the pitch.
How does this satisfy NIS2 / ISO 27001 / Cyber Essentials Plus?
All three frameworks are converging on Zero Trust principles. NIS2 explicitly references network segmentation and access control. ISO 27001 Annex A covers identity, access, and segmentation controls. Cyber Essentials Plus rewards strong segmentation and MFA on remote access. Our designs produce control-mapping documents for each framework you operate under.
