Compliance Evidence
That Proves Itself
Every piece of evidence — verified from the moment it's created.
Cryptographically signed. Independently verifiable. Yours forever.
What is NebulaProof?
The First Forensic-Grade Compliance Evidence Platform
Other compliance platforms say "trust us." NebulaProof delivers mathematical verification. Every piece of evidence — screenshots, policy docs, pen test reports, auto-generated proofs — is cryptographically signed, timestamped, and independently verifiable from the moment it's created.
How It Works
Capture evidence with our browser extension, upload traditional documents, or let the platform auto-generate proofs. Everything gets encrypted, signed, and Merkle-chained:
- Deletion requests: 30-second certificate vs 3-week manual evidence gathering
- Data residency: Geographic attestations proving "EU data stayed in EU"
- Multi-cloud distribution: Evidence across Amazon, Microsoft, AND Google—single vendor breach can't touch your data
The Difference
Audit prep drops from $8,000-15,000 in billable hours to zero. Compliance officers get self-service evidence portal. If you fire us, you keep your data—it's in your accounts.
Who This Is For
Healthcare (HIPAA), financial services (SEC/FINRA), legal (privilege protection), or any organization where auditors won't accept "trust us."
Sound familiar?
If you've been through a compliance audit, you know the pain. We built NebulaProof because we lived it too.

* Control counts reflect the number of framework requirements where NebulaProof can automate evidence collection, mapping, or continuous monitoring. Counts are based on official framework publications (AICPA TSC 2017, HIPAA Administrative/Technical/Physical Safeguards, GDPR Articles 5-49, ISO 27001:2022 Annex A, PCI DSS v4.0, NIST CSF 2.0) and may vary based on your organization's scope.
How NebulaProof Works
Three steps to verifiable compliance evidence
1. Capture
Install the browser extension. Click capture. Every screenshot becomes a cryptographic event — signed with your identity, timestamped, and hashed at the moment of creation.
2. Prove
Evidence is encrypted with your keys, counter-signed by our server, anchored in a Merkle tree, and RFC 3161 timestamped. Seven-stage chain of custody — zero gaps.
3. Verify
Send your auditor a link. They verify independently — no login, no vendor trust required. Mathematical proof, not promises. Evidence that proves itself.
Three layers of cryptographic protection
From browser to vault — every step is signed, encrypted, and independently verifiable.
Browser (Capture)
Evidence captured & signed in YOUR browser
Transport (Encrypt & Prove)
Encrypted before leaving your device
Storage (Distribute & Protect)
Distributed across 3+ cloud providers
Mathematical Proof vs Trust-Based Attestation
Traditional compliance platforms ask you to trust them. NebulaProof lets you verify for yourself.
Trust-Based Platforms
Vanta, Drata, Sprinto
- ✕Screenshots anyone could fabricate
- ✕No proof of when evidence was captured
- ✕Vendor holds your data in plaintext
- ✕No independent verification — trust the platform
- ✕Evidence can be altered after collection
- ✕No chain of custody from capture to audit
Trust-based vs Proof-based
NebulaProof
Verify It Yourself
- Every capture Ed25519 signed at moment of creation
- RFC 3161 timestamps prove exactly when
- Zero-knowledge encryption — we never see your data
- Auditor verifies independently — no login needed
- 7-stage chain of custody, zero gaps
- Export your evidence anytime — yours forever
What Auditors Actually Ask
Every question below has a one-click cryptographic answer
The Audit Evidence Gap
Compliance audits (SOC 2, HIPAA, GDPR, PCI-DSS) require verifiable evidence — not screenshots that could have been fabricated, not PDFs that could have been altered, not timestamps that could have been spoofed. Auditors spend 60-80% of their time requesting, re-requesting, and manually verifying documentation they fundamentally cannot trust.
NebulaProof closes this gap. Evidence is cryptographically signed at the moment of capture — before it leaves the browser. Auditors receive a verification link, click it, and see mathematical proof: who captured it, when, from where, and that it hasn't been altered since. Verification takes seconds, not weeks.
Auditor asks:
"When was this evidence collected?"
RFC 3161 timestamp embedded in the proof envelope at capture. Independently verifiable against public time authority. Not a file system timestamp — a cryptographic one.
Auditor asks:
"Has this been altered since collection?"
SHA-256 content hash + Ed25519 signature computed before evidence left the browser. Any modification breaks the signature. Tamper-evident by design.
Auditor asks:
"Who captured this and from where?"
User identity, URL, DOM hash, response headers, and browser metadata — all signed into the proof envelope. Chain of custody starts at the moment of capture.
Auditor asks:
"Can I verify this independently?"
Yes. One link. No login. No vendor trust. The auditor portal verifies signatures, timestamps, and Merkle inclusion proofs — all with public keys. Math, not promises.
Auditor asks:
"Is PII properly handled?"
In-browser redaction with signed attestation proves PII was removed before data left the device. Before/after content hashes in the proof chain. Original never uploaded.
Auditor asks:
"Are controls actually enforced?"
Policy snapshots captured at evidence collection time. Active policies, enforcement status, and extension version hash — all signed into the proof envelope. Not configured. Enforced.
SOC 2 Type II
The US standard that unlocks enterprise deals worldwide
Continuous evidence for Trust Services Criteria. Proof of access controls, encryption enforcement, and availability — captured and signed automatically.
HIPAA
Required for healthtech serving the US market
PHI redaction attestations, proof of client-side encryption, BAA-ready infrastructure, and cryptographic deletion certificates for patient data.
GDPR
Mandatory for any company touching EU data — from anywhere
Right-to-erasure proofs, data residency verification, consent audit trails, and proof of data minimization via redaction attestations.

Built for the Way Compliance Actually Works
NebulaProof replaces manual evidence gathering with cryptographic proof. Here is what that means for your team.
For compliance leads preparing a SOC 2 audit
Evidence is captured continuously and signed at collection time. When your auditor asks for proof, you hand them a bundle they can verify independently with our open-source kit — no back-and-forth emails requesting screenshots.
Audit prep becomes an export, not a project
For CISOs handling PHI
Redaction attestations and deletion proofs let you demonstrate PHI handling mathematically instead of by assertion. Every step in the chain of custody is signed, timestamped, and independently verifiable.
Provable chain of custody for every record
For engineering teams that hate lock-in
