📊 Risk Delta (ΔHTS)
ΔHTS = HTS(State B) - HTS(State A)
A negative delta denotes risk mitigation (e.g. -78 pts), while a positive delta immediately flags security regressions (e.g. +62 pts upon adding unconstrained tools to an AI agent).
Select a comparative scenario below to inspect side-by-side differences between State A and State B, or use the interactive live simulator at the bottom to test defensive configurations in real-time:
Quantitatively measure the security gain or risk regression between two states: before/after patch, AI agent v1 vs v2, SBOM manifest, or Zero-Trust architecture. Assess the Risk Delta (ΔHTS), trajectory shift, and blast radius impact.
As formalized in Section 18 of the Hermes Strategic Master Plan, Security Delta evaluates state transitions across 4 objective vectors:

📈 Trajectory Shift
Inflection Point Transition
Tracks whether the change successfully pulled an asset out of Critical Acceleration down into Stable, or inadvertently triggered weaponization momentum.
🌐 Exposure Delta
Attack Surface & Interface Reduction
Measures changes in open network listening ports, public perimeter reachability, unauthenticated endpoints, and unprivileged user namespace exposure.
💥 Blast Radius Delta
Lateral Movement & Privilege Boundary Shift
Quantifies worst-case impact containment: from unrestricted domain takeover down to isolated sandbox container execution.
Security Delta applies universally across modern engineering operations:
| Paradigm | State A (Baseline) | State B (Target) | Primary Analytical Goal |
|---|---|---|---|
| Vulnerability Patching | Unpatched runtime (CVE-2025-39964) | Backported fix + hardened sysctl | Prove that weaponized execution primitives are completely severed. |
| Agentic AI Autonomy | Sandboxed read-only agent | Agent with SQL + MCP filesystem | Identify dangerous capability expansions before deploying to production. |
| SBOM Evolution | Manifest v2.4 (legacy dependencies) | Manifest v2.5 (sanitized targets) | Verify that dependency upgrades eliminated known KEV vulnerabilities. |
| Architecture Modernization | Legacy VPN / Direct RDP | Zero-Trust (ZTNA + JIT bastion) | Quantify the elimination of lateral network movement pathways. |
