Introducing the
DDSATDigital & Data Sovereignty Assessment Tool
A structured, evidence-based framework to benchmark your organisation’s digital sovereignty posture across 14 domains, 5 pillars, and 84 assessment criteria.
What is DDSAT?
Measure. Benchmark. Strengthen.
Your Digital Sovereignty.
DDSAT is Talisman Cybersecurity’s proprietary Digital & Data Sovereignty Assessment Tool — a rigorous methodology that enables governments, regulators, and critical infrastructure operators to establish a quantified baseline of their sovereignty posture.
Unlike generic IT audits, DDSAT applies a maturity-based scoring model across all dimensions of digital sovereignty: from data residency and encryption key control to AI governance and institutional oversight capacity.
The output is a Digital Sovereignty Index (DSI) — a single composite score (0–100) with full domain-level breakdowns, 12 executive KPIs, and a prioritised remediation roadmap.
Quantifiable Digital Sovereignty Index
Weighted composite score (0–100) with pillar breakdown and maturity classification.
Encryption & Key Sovereignty
Assess HSM deployment, key management policies, and cryptographic independence from foreign vendors.
AI Governance & Sovereignty
Evaluate AI risk governance, model transparency, national AI strategy alignment, and data sovereignty in AI pipelines.
Critical Infrastructure Protection
Audit CNI designation, incident response (CSIRT/SOC), and foreign investment review mechanisms.
12 Executive KPIs
Traffic-light KPI dashboard with strategic thresholds — ready for board-level reporting and regulatory submissions.
Five-Pillar Assessment Architecture
Each pillar is independently weighted and aggregated into the Digital Sovereignty Index (DSI).
How the Assessment Works
From scoping to your Digital Sovereignty Index in four structured phases.
The Digital Sovereignty Index (DSI)
DDSAT produces a single composite DSI score (0–100) built from five weighted pillar scores. Every score maps to one of five maturity levels — from Initial to Optimizing.
The sample below reflects a typical mid-sized government directorate engaging in their first sovereignty assessment — strong on Legal alignment, with clear improvement areas in AI Governance and Cloud Sovereignty.
