Advisory · Security Architecture

A Zero Trust design your team can actually build.

We review how identity, network, cloud and data fit together today, design the target state, and turn it into a phased plan with owners and milestones.

Scope

What we cover.

Pick what matters for this engagement. We help you scope it in the first call.

Zero Trust strategy

Target architecture, micro-segmentation and maturity scoring against CISA's model.

Identity and access

SSO, MFA, privileged access, service identities and joiner-mover-leaver flows.

Cloud architecture

Landing zones, guardrails, network segmentation and CNAPP rollout.

Secure AI architecture

Model, data and tool boundaries for AI features and agents, reviewed before they ship.

Data protection

Classification, encryption, key management and data-loss controls.

Post-quantum readiness

A cryptography inventory and a migration plan for quantum-safe algorithms.

Methodology

How the engagement runs.

Five steps, the same on every engagement, with a named lead from scoping to sign-off.

  1. 01

    Discover

    Interviews, config reviews and diagrams to understand the current state.

    Output: Current-state map

  2. 02

    Assess

    Score maturity per pillar and find the paths an attacker would use.

    Output: Maturity scorecard

  3. 03

    Design

    Agree a target architecture that fits your stack and budget.

    Output: Target architecture

  4. 04

    Plan

    Sequence the work into phases with owners, effort and quick wins first.

    Output: Phased roadmap

  5. 05

    Support

    Stay on to review designs and changes as your team builds.

    Output: Design reviews

Deliverables

What you walk away with.

Written for the engineers who fix things and the leaders who fund them.

  • Named lead for the whole engagement
  • Critical issues flagged the same day
  • Retest included
How we work
01

Current-state assessment

Architecture diagrams and maturity scores per Zero Trust pillar.

02

Target architecture

The design you are building toward, with key decisions recorded.

03

Phased roadmap

12–24 months of work with owners, effort and dependencies.

04

Design support

Ongoing review of designs and changes as the plan is delivered, in hours set in your SOW.

FAQ

Questions we hear most.

Do we have to buy new tools?

Not necessarily. We start from what you own and recommend new spend only where it closes a real gap.

Can you help with implementation?

Yes. We can review your team's designs, or pair with your engineers on the hardest parts.

Is this only for large enterprises?

No. The scope scales; growth-stage teams often need the identity and cloud parts most.

What about post-quantum cryptography?

We inventory where cryptography is used and plan a migration as standards and vendors mature.
