What It Is

Sekura FileLock is a local, file-level encryption tool from Sekura LLC, designed for Windows 10/11 64-bit and macOS 12+. Its key selling points are AES-256-GCM encryption, Argon2 key derivation, a BIP39 24-word recovery phrase, and a zero-knowledge architecture: files and keys are not uploaded, and the app generally runs offline. An internet connection is only required for initial license activation, payment processing, and license checks during the refund guarantee period.

Core Capabilities

In terms of protection type, this is not a traditional antivirus or EDR product, but a tool for protecting sensitive documents. After creating a master password, users add files to a Vault and can enable real-time automatic protection. Its on-device scanning can identify sensitive information such as SSNs, credit cards, and passwords. The official materials list support for formats including PDF, DOCX, XLSX, TXT, JSON, XML, CSV, MD, HTML, RTF, and ODT, while the FAQ notes that scanning is based on Apache Tika and can cover additional formats. However, media files such as images and videos are not currently a main focus for encryption. Management features include password changes, 2FA, license deactivation and migration, a risk map, and protection status visualization. Centralized auditing, SIEM, SSO, or policy deployment capabilities are not apparent.

Pricing and Deployment

Pricing is straightforward: a one-time purchase of $39.99 for a single-device license, including v1.x lifetime updates and priority email support, with no subscription or auto-renewal. It also comes with a 30-day money-back guarantee. Payments are processed by Paddle, with support for credit cards, debit cards, and PayPal. Additional purchases are required for multiple devices, and volume licensing requires contacting support.

Pros and Cons

Its strengths are that it is local-first, zero-knowledge, and built on mature cryptographic components, making it suitable as a file-level protection layer alongside BitLocker/FileVault. Encrypted files can also be backed up normally to cloud drives or external drives. The drawbacks are equally clear: the app itself is proprietary, with no disclosed third-party security audit or compliance certification; if the password and recovery phrase are lost, recovery is impossible; the Find feature depends on Java 11+ and Apache Tika; and enterprise-grade management and alerting capabilities are limited.

Who It’s For and Access from China

Sekura FileLock is better suited to individuals, freelancers, and small teams looking to protect text-based sensitive documents such as financial records, contracts, and identity materials. It is not ideal for enterprises that require unified control, compliance reporting, and security operations across all endpoints. The source material does not provide details on access from mainland China. Since payments rely on international credit cards/PayPal/Paddle, actual availability should be verified independently. Alternatives to consider include VeraCrypt, Cryptomator, BitLocker, and FileVault.
