SOC 2 Trust Services Criteria Mapping
Alignment with AICPA Trust Services Criteria (Security, Confidentiality, and Privacy).
| Criterion | Control Domain | Status | Technical Implementation |
|---|---|---|---|
| CC6.1 | Logical Access Controls | Implemented | Strict Principle of Least Privilege (PoLP); non-root container execution (UID 1000) and MFA enforced across internal infrastructure. |
| CC6.6 | Boundary Protection & Network Safety | Implemented | Strict SSRF barrier with pre-flight DNS resolution, anti-DNS rebinding, Playwright route aborts, and RFC 1918/cloud metadata blocking. |
| CC6.7 | Transmission Security | Implemented | Enforced TLS 1.3 with modern AEAD cipher suites across all audit engines and API telemetry ingress. |
| CC6.8 | Financial & Autonomous Commerce Integrity | Verified | Google AP2 & x402 machine payment verification, delegated spending ceiling enforcement, and HMAC-SHA256 digital signature receipts. |
| CC7.2 | Threat Detection & Reflex Screening | Active | Sub-50ms TypeSafe AI Jev V13 reflex engine screening incoming payloads and tool schemas for OWASP LLM01 (Prompt Injection). |
| C1.1 | Confidentiality of Data | Verified | Zero-retention architecture. Audited HTML, DOM trees, and scripts execute ephemerally in RAM only; zero payload bytes written to disk. |
| P1.1 | Privacy Notice & Consent | Compliant | Client-side SDK strips all arguments and potential PII before emitting telemetry beacons. |
Infrastructure & Zero-Trust Runtime Isolation
Engineered according to the Principle of Least Privilege (PoLP) and defense-in-depth architecture to ensure host integrity, network boundary isolation, and zero lateral movement risks during headless audits.
Zero-Retention / RAM-Only Payload Isolation
Volatile RAM Only • 0 Bytes Written to DiskTarget website DOM structures, scraped source codes, tool invocation ASTs, and user payloads exist exclusively within volatile process memory (RAM-only). Chromium process contexts run with all disk caching disabled, guaranteeing zero DOM snapshots, execution traces, or telemetry payloads are written to non-volatile storage. Upon audit conclusion, browser contexts and memory buffers are immediately purged and deallocated.
Strict SSRF & Private Network Barrier
Pre-Flight DNS • In-Flight Playwright Route InterceptionDual-stage Server-Side Request Forgery barrier enforces pre-flight URL protocol validation and zero-cache DNS resolution, immediately aborting non-HTTP schemes and restricted network ranges: loopback (127.0.0.0/8, ::1), RFC 1918 private subnets (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16), link-local (fe80::/10, fc00::/7), and cloud metadata (169.254.169.254). All non-standard IPv4 notations (DWORD, octal, hex, BSD shorthand) are parsed and blocked. Playwright page.route('**/*') intercepts all sub-resources and redirect chains, aborting unapproved targets with accessdenied, backed by socket-level response.serverAddr() verification.
Sub-50ms Reflex Threat Neutralization
TypeSafe AI Jev V13 • OWASP LLM01 GateIntegrated System 1 reflex routing powered by TypeSafe AI Jev V13 classifies incoming agent payloads and DOM opportunities under 50ms. Defends against OWASP LLM01 (Prompt Injection), indirect injection embedded within website DOM nodes or microdata, rogue instruction injection, and anomalous parameter mutations before any agent delegate executes.
Agent-to-Agent (A2A) Commerce Security
Google AP2 • x402 Standards • HMAC-SHA256 SignaturesProgrammatic machine commerce transactions conform to Google AP2 (Agent Payment Protocol) and x402 standards. Enforces cryptographic delegated mandate verification, nonces, timestamps, and hard user spending ceiling caps (preventing unauthorized agent financial commitments). Every settlement generates an HMAC-SHA256 digital signature receipt guaranteeing non-repudiation and immutable transaction ledgering.
Kernel-Level Filesystem Immutability
Read-Only Container Root • Non-Root UID 1000Production container runtime runs with a locked, read-only root filesystem (--read-only). Application binaries (.next/standalone, public) are strictly owned by root:root with read-only runtime permissions (555) and executed by an unprivileged node user, completely preventing runtime binary alteration or arbitrary disk tampering. Persistent SQLite storage is isolated to a dedicated volume (/data, 770) for WAL/SHM locks.
Ephemeral Chromium Context Sandboxing
Isolated Browser Instances • 100% Termination SLAHeadless Chromium inspection sessions execute inside completely isolated, short-lived browser contexts created on-demand. Cookies, storage, service workers, and DOM memory caches are immediately purged upon audit completion, guaranteeing zero cross-session state leakage or credential residue.
Independent Verification & Test Reproduction CLI
Enterprise auditors and security evaluators can execute our automated test suites directly to independently verify system guarantees:
Validates RFC 1918 private subnets, cloud metadata (169.254.169.254), DWORD/hex/octal IP formats, anti-DNS rebinding, and Playwright route-blocking barriers.
Verifies Google AP2 autonomous checkout, user-delegated spending ceilings, HMAC-SHA256 signature generation, and malformed token rejection.
Verifies mathematical scoring determinism across the 4 diagnostic pillars, deduction weights, and W3C WebML-CG rubric compliance.
