Paperless-ngx is a system that scans paper documents, performs OCR, and stores them as searchable files. It is used by teams to ensure they don't lose important records like invoices and contracts. A search revealed thousands of assets with "Paperless" in their HTML title, though not all are Paperless-ngx. Document archives can be highly sensitive as they essentially act as identity records containing personal and financial details. Metadata like correspondent names, tags, and dates further describes relationships, budgets, and timelines. Common security mistakes in self-hosted Paperless-ngx deployments include leaving old accounts active and making the archive publicly accessible without a VPN. Older versions may have unpatched vulnerabilities. To improve security, one should restrict public access, ensure the system is updated, enable multi-factor authentication, and regularly review user accounts. Backups should be stored separately from the main archive. Exporting the index allows for reconstruction of what was stored even if the archive is lost.
