ProofLayer

Continuous Compliance Evidence

Compliance That Proves Itself

ProofLayer continuously evaluates control-state and produces cryptographically signed evidence — exposed as a structured API stream that feeds directly into your System of Record. SAP stays current. SAR reflects reality. POA&Ms close themselves. The evidence pipeline replaces the reconciliation cycle.

The Evidence Problem

If Compliance Feels Expensive and Fragile, It’s Because It Is

Every assessment cycle starts the same way — teams scramble to collect evidence, reconcile artifacts, and assemble documentation that proves controls were enforced. Not right now. Months ago. The result is a compliance program that costs more, takes longer, and still leaves gaps an assessor will find.

SAP 4–6 weeks to draft, reviewed once a year. Describes what should happen, not what did.
SAR Assembled manually from screenshots, exports, and interviews. Outdated before submission.
POA&Ms Opened in spreadsheets, status tracked via email, closed when someone remembers.
Evidence Collection 2–3 analysts spending 40+ hours pulling artifacts from five different systems for a single assessment window.
Document Preparation Weeks of formatting, cross-referencing, and version control to produce packages an assessor can actually review.

The problem isn’t your controls — it’s the months of manual labor between execution and the evidence that proves it. ProofLayer eliminates that gap.

The Evidence Pipeline

The Problem Isn’t Your Controls — It’s the Evidence Pipeline

Controls execute every second. Evidence arrives weeks later. The gap between execution and record is where compliance breaks — and where ProofLayer operates.

How It Works

Continuous Evidence with Cryptographic Proof

Every piece of compliance evidence is collected by constrained policy execution, cryptographically signed with an ephemeral identity, and verified before storage. The result is an auditable chain from policy to proof.

Policy Repository
Centralized Policy Library
version-controlled · framework-mapped
Curated security and compliance policies mapped to regulatory frameworks. Each policy defines what to check, how to collect evidence, and the expected compliant state. Policies are versioned, signed, and distributed to all daemons.
NIST 800-53 · CMMC · FedRAMP · SOC 2 · CIS
policies distributed to all managed endpoints
Managed Endpoints · Any Environment
ProofService Daemon
lightweight · continuous · runs anywhere
Deployed on every managed endpoint. Continuously evaluates policies, collects evidence, and produces cryptographically signed proof of compliance state. Only submits when state changes; heartbeats confirm ongoing compliance.

authenticate via existing credentials
Your Identity Infrastructure
Cloud IAM / Identity Provider
AWS IAM · Azure Entra ID · Active Directory · OIDC
Uses your existing identity infrastructure — no new credentials. The daemon authenticates through platform-native mechanisms. The platform validates this attestation directly with your identity provider.
ZERO NEW SECRETS · PLATFORM-NATIVE
encrypted · all traffic authenticated
ProofLayer Platform · Secure Infrastructure
Trust & Identity Services
Secure Gateway
Encrypted entry point for all daemon traffic. Minimal attack surface.
Identity Verification
Validates workload identity against your cloud provider. Issues short-lived cryptographic tokens.
Certificate Authority
Issues ephemeral signing certificates (1-hour validity). Chains to your organization’s root of trust.
Transparency Log
Append-only, tamper-evident log of all certificate issuances. Signed Merkle checkpoints enable independent audit.
Signature Verification
Validates every piece of evidence before storage — certificate chain, signature, and transparency proof.
Evidence Services
Evidence Store
ingest · query · transform · export
Receives cryptographically verified scan results. Every piece of evidence is validated before storage. Serves compliance data to systems of record, assessors, and dashboards.
VERIFIED INGEST · OSCAL EXPORT · FRESHNESS TRACKING
Evidence Database
encrypted at rest · private network
Scan results, policy outcomes, evidence artifacts, control mappings, and freshness timestamps. Supports the full OSCAL data model.
OSCAL-READY · AUDIT COMPLETE
Freshness Monitoring
Tracks when each endpoint last reported. Heartbeats confirm ongoing compliance. Detects stale endpoints in real time.

Stop Preparing for Assessments. Stay Ready for Them.

Assessment preparation exists because evidence is disconnected from execution. Teams spend months collecting, reconciling, and packaging proof that controls were enforced — not because the work is hard, but because the pipeline doesn’t exist. ProofLayer replaces that cycle with a continuous evidence stream. Your System of Record stays current. Your artifacts reflect reality. When the assessor arrives, the work is already done.

One Evidence Stream. Every Consumer.

GRC Platform

Structured control-state feeds keep SAP and SAR artifacts current without manual updates.

Assessor Toolchain

Evidence packages assembled on demand from signed proof — not screenshots and spreadsheets on deadline.

SIEM / SOAR

Control-state signals enrich detection and response with compliance-aware context.

POA&M Tracking

Deficiencies opened, tracked, and closed from evidence. No spreadsheets. No email chains.

Every consumer draws from the same canonical evidence. No reconciliation. No drift. One source of truth.
