Enterprise File Integrity & Evidence

The Problem: Proving Nothing Was Touched

When the auditor, the investigator, the insurer or the court asks the hard question — "can you prove this file, this log, this configuration is exactly what it was?" — most teams cannot answer with certainty. Critical files, security logs and incident artifacts pass through many hands and systems, and "we're pretty sure it's unchanged" does not hold up under scrutiny. A single altered byte in a golden image, an audit log or a captured artifact can quietly undermine an entire investigation or compliance position. What enterprise security needs is a repeatable, independently checkable way to demonstrate integrity — not a promise, but proof.

How e-Dex Helps

e-Dex gives security teams a single, local workflow for integrity and evidence. You baseline and re-verify critical files — configuration, golden images, policy documents and audit logs — by computing a cryptographic hash and confirming it on demand. You preserve incident-response evidence by fingerprinting each artifact with a hash and a trusted timestamp at the moment of collection, producing tamper-evident logs that show what was seen and when. e-Dex then issues signed certificates and bundles a batch into a self-verifying evidence pack that any recipient can re-validate against a manifest. Everything runs 100% offline with no telemetry, so sensitive material never leaves the host without your consent.

Outcomes for Security Teams

Used as part of your day-to-day controls, e-Dex turns vague assurance into hard evidence:

• Audit-ready integrity — prove critical files and logs are unchanged with a signed, one-page certificate auditors can verify independently.
• Defensible investigations — every incident artifact carries a hash and timestamp, so the evidence stands up internally, with regulators and in court.
• Faster, calmer breach response — freeze a tamper-evident record of what responders collected in the critical first hour.
• Stronger insurance posture — give underwriters verifiable proof that backups and evidence are intact and untouched.
• Zero data exposure — no cloud account, no agent phoning home, no sensitive file leaving the host.

For practical playbooks, see our notes on the first 60 minutes of a breach, proving SIEM logs are unaltered, and the backup evidence cyber-insurance underwriters want.

Built for Enterprise Trust

e-Dex is designed to satisfy the security review, not work around it. It runs fully offline on a single Windows host, so no data leaves the machine without consent and there is no background telemetry to whitelist or audit. It is built to global, open standards — PAdES digital signatures, RFC-3161 trusted timestamps and BagIt self-verifying evidence packs — and, for teams operating in India, supports records suitable for Section 63 of the Bharatiya Sakshya Adhiniyam (formerly Section 65B). Outputs are open and machine-readable (hashes, manifests, and certificates in HTML, JSON and XML), so there is no proprietary container to escape and no lock-in.

Frequently Asked Questions

What is an enterprise file integrity and evidence tool?
It is a tool that lets a security team prove that critical files, logs and incident artifacts have not been altered. e-Dex computes a cryptographic baseline hash for each file, re-verifies it on demand to confirm nothing changed, and packages the result as a signed, timestamped integrity certificate — so the evidence is provable for audits, investigations, insurers and courts rather than merely assumed.

Does e-Dex run fully offline with no telemetry?
Yes. e-Dex is a free Windows application that runs entirely on the host. Baselining, re-verification, certificate generation and evidence packaging all happen locally, and no data leaves the machine without consent. There is no background telemetry. The only optional outbound call is to apply an RFC-3161 trusted timestamp, which a SOC can disable for fully air-gapped operation.

How does e-Dex help during incident response?
When responders collect logs, memory captures, configuration files and other artifacts, e-Dex fingerprints each one with a cryptographic hash and a trusted timestamp at the moment of collection. That freezes a tamper-evident record of what was seen and when, so the evidence stands up later for internal review, regulators, cyber-insurance claims or legal proceedings.

Which standards does e-Dex align with?
e-Dex builds on global, open standards: PAdES for digital signatures on PDF certificates, RFC-3161 for trusted timestamps, and BagIt for self-verifying evidence packs. For organisations operating in India it also supports records suitable for Section 63 of the Bharatiya Sakshya Adhiniyam (formerly Section 65B of the Indian Evidence Act), so the same workflow serves both global and Indian compliance needs.

Can e-Dex monitor file integrity for compliance audits?
Yes. You baseline a set of critical files — configuration, golden images, policy documents, audit logs — and re-verify them on a schedule or before an audit. A match proves the file is bit-for-bit unchanged since baseline; a mismatch flags tampering immediately. Each verification can be exported as a signed certificate, giving auditors a one-page, independently checkable integrity record.
