Zero Trust (CISA ZTMM)

Practice: Cybersecurity · Type: Model

Zero Trust is a security model that assumes no implicit trust and verifies every request. The CISA Zero Trust Maturity Model (ZTMM) rates maturity across five pillars — identity, devices, networks, applications & workloads, and data.

Benefits​

  • Scored on the CISA ZTMM's own maturity scale across all five pillars — not a generic rubric.
  • Every score is traceable to the client's own architecture and control evidence.
  • Gaps sequenced by the moves that improve posture fastest.
  • A board-ready slide deck and a detailed report generated automatically.
  • Re-runnable to track the journey from traditional toward optimal maturity.

When to use it​

  • To baseline an organisation's zero-trust maturity across all five pillars.
  • When a client is building or accelerating a zero-trust programme.
  • To sequence the highest-leverage architecture changes first.
  • To measure posture improvement as zero-trust capabilities mature.

What it assesses​

Celeredge rates the client's zero-trust maturity across the five CISA pillars and cross-cutting capabilities, and sequences the gaps that move posture fastest. It covers:

  • Identity
  • Devices
  • Networks
  • Applications & workloads
  • Data
  • Cross-cutting capabilities

Expected output​

Celeredge produces per-pillar maturity scores on the CISA ZTMM scale. Each answer carries a confidence signal and citations back to the client's evidence, and gaps are ranked by severity. The run generates a board-ready slide deck and a detailed HTML report. See Maturity Scoring, Reports and Deck Studio.

How to use it in Celeredge​

  1. Collect the client's evidence — architecture, identity and control records — see Evidence Collection.
  2. In Diagnose, select Zero Trust (CISA ZTMM).
  3. Run the assessment and watch it stream — see Running Assessments.
  4. Review per-pillar answers with their confidence and citations, then accept the ones you trust.
  5. Send gaps to Plan — see Gap Analysis.

FAQ​

What is Zero Trust?​

Built on the principle of no implicit trust and verification of every request, Zero Trust is a security model. CISA's Zero Trust Maturity Model (ZTMM) measures progress toward it across five pillars: identity, devices, networks, applications & workloads, and data.

What does a Celeredge Zero Trust assessment deliver?​

An evidence-based maturity assessment scored on the model's own scale, with gaps ranked by severity and an auto-generated, board-ready slide deck and detailed report — every score traceable to the evidence behind it.

How does the assessment work?​

Clients upload their own evidence — policies, reports and data. An AI interviewer asks targeted follow-ups to fill anything missing, the platform scores against the framework, ranks the gaps, and generates the deliverables.
