GetProofAnchor - 2026 Pricing, Features, Reviews & Alternatives

GetProofAnchor is a web based evidence capture and verification platform designed to create tamper-evident records of online content for legal, investigative, compliance, and archival purposes. The software enables organizations and professionals to capture web pages including content behind authentication barriers and generate cryptographically verifiable evidence packages that can be independently validated for integrity. The platform serves lawyers, investigators, journalists, brand protection teams, compliance officers, and reputation management professionals who require defensible documentation of online content that may be subject to modification or deletion.

The platform offers two capture methods: public URL capture for publicly accessible pages and a browser extension for capturing authenticated content visible only to logged-in users such as social media posts, private profiles, or restricted platform content. Each capture generates a unique Proof ID and produces an Evidence ZIP package containing multiple verification artifacts. The Evidence ZIP includes a screenshot of the captured page, extracted content when available, the original HTML source, proof metadata, a manifest file containing Secure Hash Algorithm two hundred fifty-six cryptographic hashes of all included files, an eIDAS-qualified timestamp from an EU-accredited trust service provider, and blockchain anchoring data via OpenTimestamps referencing the Bitcoin network. The platform implements a four-layer trust stack for integrity verification including a Secure Hash Algorithm two hundred fifty-six file manifest that records cryptographic fingerprints of every file, an append-only hash chain in which each capture links to the previous entry to prevent insertion or modification of historical records, blockchain anchoring on the Bitcoin network to preserve timestamps independently of the capture platform, and eIDAS-qualified timestamps that provide legally recognized proof of existence under applicable European electronic trust services regulation. The verification system produces deterministic match or modified results with per-layer reporting that identifies exactly which integrity layer failed if tampering is detected. The platform supports self-service capture workflows and an assisted service option in which staff perform captures on behalf of clients, delivering court-ready evidence packages within specified service-level agreements ranging from sixty minutes to six hours depending on urgency and package size.

GetProofAnchor provides a public verification interface that accepts either Proof IDs or uploaded Evidence ZIP files for offline integrity checking, enabling third-party reviewers, legal counsel, expert witnesses, or opposing parties to independently validate evidence without requiring platform access or vendor dependency. The verification process recalculates Secure Hash Algorithm two hundred fifty-six hashes for all files and compares them against the original manifest, validates the integrity of the hash chain, verifies the blockchain anchor on the Bitcoin network, and confirms the eIDAS timestamp signature. The Evidence ZIP format serves as a portable integration mechanism for document management systems, legal case management platforms, compliance repositories, or forensic analysis workflows without requiring direct system integrations. Blockchain anchoring via OpenTimestamps ensures that timestamp verification remains possible even if the vendor ceases operations.

The platform adheres to international forensic chain-of-custody principles by applying cryptographic hash manifests, timestamps, and traceability mechanisms that ensure any modifications to captured evidence become mathematically detectable during subsequent verification. The browser extension captures authenticated content on social media platforms to preserve posts, profiles, and comments that may later be edited or deleted. Proof IDs and Evidence ZIP packages provide a consistent point of reference for integrity verification by third-party reviewers, legal counsel, expert witnesses, or opposing parties without requiring access to the capture platform.
