Architecture · Zero Trust

Zero Trust architecture, sequenced into work your teams can actually do

Zero Trust is an architecture and a sequencing problem, not a product you buy. Cyberneza assesses where you are against a recognized maturity model, agrees a target state that someone can actually be held to, and hands your teams a design and a roadmap ordered by dependency and risk — for federal programs working to OMB M-22-09 and the DoD Zero Trust Strategy, and for commercial teams whose auditors and enterprise customers keep asking the same access-control questions.

First principles

What Zero Trust is — and what it is not

Zero Trust is a set of design principles: no implicit trust from network location, access decided per request against identity, device posture and context, least privilege enforced continuously, and the assumption that a breach has already happened. Everything else is implementation detail.

What it is

  • An architecture decision, expressed as policy enforcement points and the data those points need
  • A migration — existing systems move toward it in a deliberate order, not on a flag day
  • A measurable position: for each capability, where you are today and where you intend to be
  • Identity-first. Almost every other pillar depends on identity being right first.

What it is not

  • A product. No vendor sells Zero Trust; vendors sell components that a Zero Trust design may use.
  • A synonym for microsegmentation, or for replacing the VPN
  • A compliance framework with a certificate at the end
  • An all-or-nothing programme. A partial implementation with a written target state is a normal, defensible position.
Reference models

The Zero Trust models the work is grounded in

Guidance is tied to published sources rather than to a vendor's architecture diagram, so the position you take can be shown to an assessor, an authorizing official, or a customer's security team.

NIST SP 800-207

The reference definition of Zero Trust Architecture — tenets, logical components (policy engine, policy administrator, policy enforcement point), deployment variations, and the trust algorithm. This is the vocabulary the rest of the models assume.

CISA Zero Trust Maturity Model v2

Five pillars — Identity, Devices, Networks, Applications & Workloads, Data — plus visibility and analytics, automation and orchestration, and governance across all of them. Its four stages give a per-capability current and target state instead of one subjective score.

OMB M-22-09

The federal Zero Trust strategy memorandum and its specific expectations — enterprise identity with phishing-resistant MFA, a device inventory, encrypted traffic, application testing and internal accessibility, and data categorization. Where federal customers get their questions.

DoD Zero Trust Strategy

Seven pillars and the target-level capability activities defense programs are being measured against. Relevant to primes and subcontractors whose programme plans now have to state a Zero Trust position.

Commercial framework mapping

The same design decisions are mapped to SOC 2 logical-access criteria, ISO/IEC 27001 Annex A access and network controls, and CIS Controls v8 — so one architecture answers the auditor and the enterprise security questionnaire rather than needing a second story.

NIST SP 800-171 and CMMC

Neither requires Zero Trust. But the access-control, identification-and-authentication and audit families ask for exactly what a Zero Trust design produces, so the two are sequenced together rather than as competing programmes. See CMMC & NIST 800-171 readiness →

The approach

How a Zero Trust engagement runs

The same four-stage delivery model the rest of the practice uses. See the full methodology →

1

Position

Assess the current state per pillar against the maturity model that applies to you, using your existing identity, endpoint, network and data tooling as the evidence. The output is a current position with the reasoning attached, not a score.

2

Target

Agree a target state per capability, and write down what it is deliberately not. A target nobody signed is the reason most Zero Trust programmes cannot say whether they are finished.

3

Sequence

Order the work by dependency and risk — identity foundations before conditional access, device signal before device-based policy, inventory before segmentation — so nothing is built twice.

4

Design and support

Control design, implementation procedures and validation criteria for the sequenced work, with engineering support through it. Your teams execute production changes through your own change-management process. That is the BUILD package →

Deliverables

What you get

Maturity position

Current state per pillar and capability, with the evidence and reasoning behind each placement so the position survives being questioned.

Target-state architecture

Policy enforcement points, the identity and device signals each decision depends on, and where the boundaries sit — written in the vocabulary of NIST SP 800-207.

Sequenced roadmap

The work ordered by dependency and risk, with each step's prerequisite named, so a delay in one place has a visible consequence rather than a silent one.

Framework mapping

Each design decision mapped to the framework requirements it satisfies — federal, commercial, or both — so one piece of work answers several questions.

Validation criteria

Explicit criteria per capability, so "we have done Zero Trust for identity" becomes a test rather than an opinion.

Executive narrative

The position and the plan in language a board, an authorizing official, or a customer's security reviewer can act on without a translation layer.

Failure modes

Where Zero Trust programmes usually stall

These are the patterns the published guidance and the vendor case literature keep describing. Naming them early is cheaper than discovering them in year two.

  • The product came first. A tool was bought, then an architecture was reverse-engineered to justify it — and the gaps the tool does not cover never get named.
  • Segmentation before identity. Network work starts because it is visible, while the identity foundation every policy decision depends on is still incomplete.
  • No written target state. Without one, the programme cannot report progress, cannot be finished, and cannot be defended in a review.
  • A pilot that never leaves the pilot. One application is onboarded well and the pattern is never generalized, because nobody owns the migration sequence.
  • Policy with no telemetry. Enforcement is switched on without the visibility to tell whether it is working, so it gets loosened at the first support ticket.
  • Compliance and architecture run separately. The same access controls get implemented twice, described differently, and evidenced neither time.
Who it is for

Federal and commercial, as peer lines

Federal, defense, and their suppliers

Agencies and programme offices working to OMB M-22-09, and the primes and subcontractors being asked to state a Zero Trust position in a proposal or a programme plan. Sequenced alongside NIST SP 800-171 and CMMC work rather than competing with it.

Federal practice → · Architecture & proposal advisory →

Commercial and regulated organizations

SaaS and enterprise teams whose access-control design has to satisfy a SOC 2 or ISO 27001 audit, an enterprise customer's security review, and an insurer's underwriting questions — ideally with one architecture rather than three answers.

FAQ

Common questions

Do we have to replace our VPN to do Zero Trust?

No. Remote access is one enforcement point among many, and replacing it is a sequencing decision rather than a prerequisite. Several organizations get more risk reduction earlier from identity and privileged-access work than from changing how people connect.

Is Zero Trust required for CMMC or NIST SP 800-171?

No. Neither requires Zero Trust. The access-control, identification-and-authentication, and audit requirements do ask for the same underlying capabilities, so the two are planned together to avoid building the same controls twice.

Can you certify us as Zero Trust?

No, and neither can anyone else — there is no Zero Trust certification. What can be produced is a defensible maturity position against a published model, with the evidence behind each placement.

Do you implement the changes yourselves?

Cyberneza develops the architecture, technical recommendations, implementation procedures, configuration guidance, and validation criteria. Customer technical teams normally execute approved production changes through their established change-management process.

Are you tied to a particular vendor's Zero Trust platform?

No. Recommendations are tool-agnostic. Partner and platform relationships expand what can be delivered; they do not decide the architecture, and the design is written so it can be implemented with what you already own where that is the right answer.

What does a Zero Trust engagement cost?

It is scoped after a call, because the environment, the model you are being measured against, and the amount of engineering support required all change the work. The scope and fee are written down before the engagement begins. See how packages are priced →
