● Compiler-Driven Invariant Synthesis • Zero LLM Guardrail Latency

Deterministic Runtime Governance for Autonomous AI Agents & Microservices

InvarSec, Inc. builds enterprise cybersecurity infrastructure, native Rust/Python developer SDKs, and in-line execution gateways that validate Model Context Protocol (MCP), REST/GraphQL, and SQL tool calls in sub-millisecond latency before execution.

Inside-Out Structural Inversion Architecture

Instead of relying on probabilistic neural prompt guardrails that add 800ms+ of latency and fail against jailbreaks, InvarSec compiles your internal schemas and data structures into deterministic runtime execution boundaries.

MODULE 01 // TRAJECTORY DFA

6-Class Trajectory State Machine & Tool Shield

Maps every MCP tool, REST endpoint, DOM selector, and OS syscall into 6 discrete capability classes. Enforces strict non-interference transitions in CPU registers while blocking cross-server MCP tool shadowing and post-registration schema mutations.

MODULE 02 // STATE PINNING

Closed-Loop Read-to-Write State Pinning

Intercepts upstream read responses to bind verified entity balances, recipient destination hashes, sibling aliases, and ETag/xmin version tokens in volatile memory. Blocks parameter tampering, blind-probe oracles, and address substitution prior to dispatch.

MODULE 03 // SQL CTE COMPILER

Two-Phase SQL Concurrency Compiler

Introspects database DDL catalogs at boot to compile single-row updates into atomic conditional writes and multi-row mutations into canonical lexicographically sorted FOR UPDATE Common Table Expressions, eliminating TOCTOU double-spends and PostgreSQL 40P01 deadlocks.

MODULE 04 // IN-DRIVER 10S JIT

Receiver-Side In-Driver 10s JIT Verifier

Eliminates static API keys from agent context windows. Mints single-use, 10-second HMAC capability tokens verified directly inside the upstream database driver wrapper with a spent-nonce replay register—blocking gateway-bypass attacks.

MODULE 05 // STREAM HARDENING

Split-TCP Reassembly & Lexical Scanner

Reassembles fragmented HTTP/TCP frames up to 64 KB and executes a stack-tracked multi-depth lexical duplicate-key scanner and binary ABI byte-offset parity verifier prior to JSON deserialization, neutralizing parser-differential smuggling.

MODULE 06 // COMPLIANCE LEDGER

O(1) Ring-Buffer GDPR Merkle Flight Recorder

Records every evaluated directive into a fixed-capacity in-memory Merkle ring buffer with rolling checkpoint roots anchored to WORM storage. Supports statutory GDPR Article 17 crypto-erasure via per-subject key destruction without breaking audit chain continuity.
