//CRYPTOGRAPHICALLY VERIFIED ENFORCEMENT

AI Security That Can't Be Bypassed Or Ignored.

Every other AI guardrail is itself an AI — and AI can be jailbroken, prompt-injected, or reasoned around. PreFlight replaces model judgment with formal methods and cryptography. Every agent action gets a tamper-evident proof in under a second.

AI agents don't just assist anymore.

They transact, approve, and spend autonomously, at machine speed, with no human watching - in agentic commerce, legal, and financial workflows alike.

$1,000 $10,000,000

A vulnerability that steals $1,000 from a human-speed system steals $10 million from a machine-speed one. The exploit is identical. Only the clock changes.

Two ways to guard an agent.

Reactive, after-the-fact failure of LLM safety judges
Reactive

Most AI guardrails and observability platforms are reactive, they tell you what might have gone wrong, after it has. LLM-based safety judges are built from the same models they're meant to check.

Proactive mathematical proof attached before the action runs
Proactive

PreFlight is proactive, mathematical proof every rule was followed, before the action runs. Every decision ships with a cryptographic proof.

How PreFlight works.

01

Agent proposes an action

02

Rules compile to a formal constraint problem

03

Solver returns SAT (allowed) or UNSAT (blocked)

04

Cryptographic proof - verifiable in under one second, even for thousands of guardrail calls

Formal methods, not model judgment. Sub-second latency. Tamper-evident proofs.

//ADVERSARIAL ENVIRONMENTS

Built where the stakes are real.

Agentic commerce, legal, finance, and enterprise risk are the first places autonomous agents get real authority, and the first places a wrong action can't be undone.

01

Agentic Commerce

Agents that browse, buy, and settle payments need proof attached to every transaction, not a judgment call from the same model that could be tricked into making it.

02

Legal

Filings and contract actions executed by agents carry legal weight. Every step needs a record that holds up under review.

03

Finance

Trading and settlement agents move capital at machine speed. Every decision ships with proof.

04

Insurance & Liability

Boards and underwriters can't insure a judgment call. Cryptographic proof turns agent risk into something actually quantifiable.

//NEW: PROMPT INJECTION + PII PROTECTION

Now catching what's injected and what leaks.

Two new guardrails, same verification model: a check with a cryptographic receipt attached, succinctly verifiable.

Prompt Injection Protection

Catches injected instructions hiding in tool outputs, documents, and untrusted context, before the agent acts on them, not after.

PII Protection

Flags and blocks any action that would expose or transmit personal data outside policy, with proof attached to every check.

//AUDIT EFFICIENCY

Why log everything
when you can verify it?

Every guardrail run creates cryptographic proof. Instead of storing raw logs for thousands of agent actions, you verify a proof of all of the actions. A single check confirms the rules held across every call.

N 1

Checking N log lines becomes verifying one proof

Without PreFlight
Log every action.
Audit every log.

Storage and review costs scale linearly with agent throughput. 60,000 actions per incident — 60,000 log lines to triage.

With PreFlight
One proof.
Thousands of calls.

A single cryptographic proof attests that your guardrails held across any window of agent activity. Log costs drop. Audit time collapses.

//PROOF-CARRYING INTENT

User intent.
Every agent.
One proof chain.

Intent is fixed as a checkable predicate at the root. Every downstream agent — orchestrator, sub-agents — proves conformance. One broken link surfaces before any action lands.

A variant of IVC — Incremental Verifiable Computation
User — Root
“Buy me a plane
ticket to NYC”
π₀ = commit(intent)
Orchestrator
Splits into flight search, seat, payment sub-tasks.
π₁ = extend(π₀, action)
Sub-agent A
Finds NYC flights. Intent intact.
verify(π₁) → SAT
Sub-agent B — drift
Books LAX. Predicate violated. Blocked.
verify(π₁) → UNSAT
The predicate propagates untampered. Every upstream agent stays clean. Only the drifting node fails.

Used by the teams who can't afford a broken AI agent.

Security and platform engineers run PreFlight in front of their autonomous agents, the engineering teams shipping agentic systems that transact, approve, and spend in production.

//WHO IT'S FOR

Built for those who own the risk.

01
For CISOs

Risk you can report on, not defend.

Boards and auditors don't accept a judgment call as evidence. Cryptographic proof turns agent risk into an audit trail you can put in front of either one.

For Agent Developers

Ship verification, not judgment calls.

Drop a check in front of any tool call. SAT or UNSAT in under a second, no model in the loop.

For Compliance

Show a proof, not a log to interpret.

Every guardrail run produces a tamper-evident record for the moment an auditor asks what happened.
