Forward to: Zero Trust Team

Zero Trust Architecture
Workflows

Ten agent workflows for the Zero Trust Team — continuous domain verification, microsegmentation intelligence, identity-aware access decisions, trust score computation, never-trust-always-verify policy enforcement, lateral movement prevention, application access governance, dynamic policy adaptation, zero trust maturity assessment, and vendor zero trust posture validation — enabling data-driven zero trust decisions powered by comprehensive domain intelligence.

1Continuous Domain Trust Verification

AI agent implements continuous trust verification for every external domain accessed by users and systems — computing real-time trust scores based on 20 page types and enrichment data, replacing static allow/deny lists with dynamic trust decisions.

ZERO TRUST DOMAIN SCORING ENGINE ════════════════════════════════════════════════════════ MODEL: Never Trust, Always Verify — Domain Intelligence Edition DOMAINS SCORED: 14.2M unique daily TRUST SCORE COMPUTATION: Factor Weight Signal Domain Age 20% Older = more trusted OpenPageRank 15% Higher PR = more authoritative /security page 15% Present + certifications = trust /compliance page 10% Present = regulatory awareness Web Filtering category 15% Legitimate categories = trust Page completeness 10% More pages (of 20) = established Country risk 10% Low-risk jurisdiction = trust IAB category match 5% Expected category for claimed purpose LIVE SCORING EXAMPLES: okta.com → Trust: 97/100 Age: 6,205d | PR: 8.4 | /security: SOC2+ISO | 19/20 pages | US POLICY: Full access, no additional inspection new-vpn-client-download.com → Trust: 3/100 Age: 4d | PR: 0.0 | /security: None | 2/20 pages | Moldova POLICY: Block entirely, alert SOC startup-hr-tool.io → Trust: 41/100 Age: 189d | PR: 1.9 | /security: Basic | 8/20 pages | US POLICY: Allow with SSL inspection + DLP + session recording

Enforce Trust-Based Access Policies
Zero Trust Policy Tiers
Dynamic Access Tiers — Trust 80-100: Full access. Trust 50-79: Access with SSL decryption + logging. Trust 25-49: Access with SSL decryption + DLP + sandbox. Trust 1-24: Block with override request option. Trust 0: Hard block, no override. Scores re-evaluated every 6 hours.
5-tier dynamic policy — zero static allow lists

2Identity-Aware Domain Access Governance

AI agent combines user identity context (role, department, clearance level) with domain trust scores to make granular access decisions — ensuring that sensitive roles only access verified, high-trust domains while allowing broader access for lower-risk roles.

1
Map Identity Context to Domain Access
/login /pricing /products Personas IAB Categories Web Filtering
IDENTITY-AWARE ACCESS MATRIX ════════════════════════════════════════════════════════ ROLE: Executive (C-suite) Min domain trust for access: 60/100 Additional: All traffic SSL-decrypted, DLP on financial data Blocked categories: Gambling, Adult, Malware, Hacking Tools Domain investor-relations-portal.com (Trust: 72): ALLOW Domain quick-file-share.xyz (Trust: 12): BLOCK ROLE: SOC Analyst Min domain trust for access: None (research exemption) Additional: All access logged, sandbox for downloads Allowed categories: Including Hacking Tools, Malware (for research) Domain malware-bazaar.abuse.ch (Trust: 34): ALLOW (research) ROLE: Finance Team Min domain trust for access: 70/100 Additional: DLP for financial data, PCI domains only for payments Blocked: All uncategorized domains, all domains <30 days old Domain quickbooks.intuit.com (Trust: 95): ALLOW Domain invoice-payment-portal.net (Trust: 18): BLOCK + ALERT ROLE: Developer Min domain trust for access: 20/100 Additional: Allow package registries, documentation, API endpoints Domain npmjs.org (Trust: 93): ALLOW Domain github.com (Trust: 98): ALLOW

3Microsegmentation Intelligence

AI agent provides domain intelligence to inform microsegmentation policies — determining which external domains each network segment should be allowed to reach, based on the segment's function and the domain's verified purpose and trust level.

1
Define Segment-Specific Domain Policies
/api /products /partners IAB Categories Web Filtering Countries
MICROSEGMENTATION DOMAIN POLICIES ════════════════════════════════════════════════════════ SEGMENT: Production Database Tier Allowed external domains: 7 (explicitly verified) - Backup service: backups.aws.amazon.com (Trust: 99) - Monitoring: api.datadog.com (Trust: 96) - Patching: packages.microsoft.com (Trust: 99) All other external: DENY Verification: All 7 domains have /security, /compliance, PageRank >7 SEGMENT: CI/CD Pipeline Allowed external domains: 34 (verified registries + tools) - registry.npmjs.org / pypi.org / hub.docker.com Domain trust minimum: 50/100 New dependency domains: Auto-held for 24hr review All other external: DENY + alert DevSecOps SEGMENT: Guest WiFi Allowed: All domains with Trust >30 and Web Filtering != Malware Blocked: All domains <14 days old | All with PageRank <0.5 No access to any internal domain segments

4Trust Score Decay & Re-verification

AI agent implements trust score decay — domains that haven't been re-verified or whose enrichment data has changed must earn trust again, preventing the accumulation of stale trust that could be exploited through domain takeover or compromise.

2
Automated Re-verification Workflow
Re-verification
Trust Decay Policy — Domains lose 2 trust points per month without re-verification. Any domain dropping below its access tier threshold triggers automatic re-verification: fresh domain intelligence scan, /security page check, compliance cert validation, and PageRank trend analysis. 14 domains re-verified this week, 3 failed and were downgraded.
14 re-verifications this week — 3 failed, downgraded

5Application Access Governance

AI agent governs which web applications users can access by evaluating each application domain's security posture, compliance status, and trust score — replacing manual application whitelisting with intelligent, data-driven access decisions.

7Lateral Movement Prevention Intelligence

AI agent provides domain intelligence to detect and prevent lateral movement — identifying when compromised systems begin communicating with unusual external domains that differ from their normal baseline of trusted services.

8Dynamic Policy Adaptation

AI agent dynamically adapts zero trust policies based on changing domain intelligence — automatically tightening or loosening access controls as domain trust scores change, threat landscapes shift, or new intelligence becomes available.

10Supply Chain Zero Trust Verification

AI agent extends zero trust principles to the entire supply chain — continuously verifying the trust level of every vendor, partner, and supplier domain that connects to enterprise systems, ensuring no implicit trust is granted to any external entity.
