Just as you would put your money in a safe, would you like to keep your files in a digital ‘Locker’ that’s safer than a bank’s vault? You can create ‘Locker(s)’ which are protected by AES 256-bit encryption. You need not encrypt or decrypt files when accessing; simply copy them to Locker and voila! They are encrypted on the fly. Folder Lock offers a 2-way encryption and backup method, letting you backup your encrypted ‘Lockers’ online.

RMail® is the e-security platform by RPost®, a global leader since 2000. RMail specializes in elegantly easy to use email encryption for privacy and compliance, e-signatures, legal e-delivery proof, secure file sharing, email impostor protection, document rights management, and AI-infused services to prevent data leaks and human e-security errors. RMail’s transmission e-security services are most often used by businesspeople or business systems that send important, sensitive, or consumer-regulated information. These RMail services are generally applied to those messages where the sender needs functionality beyond standard email in terms of (a) easier to use and more automated email encryption for privacy compliance, (b) returning a verifiable proof record of who said what to whom by email, (c) assurance and peace of mind related to delivery and open status of important and time-deadline email, (d) need a timestamped proof of content delivered, (f) need to share large files securely.

Secure, store and tightly control access to tokens, passwords, certificates, encryption keys for protecting secrets and other sensitive data using a UI, CLI, or HTTP API. Secure applications and systems with machine identity and automate credential issuance, rotation, and more. Enable attestation of application and workload identity, using Vault as the trusted authority. Many organizations have credentials hard coded in source code, littered throughout configuration files and configuration management tools, and stored in plaintext in version control, wikis, and shared volumes. Safeguarding and ensuring that a credentials isn’t leaked, or in the likelihood it is, that the organization can quickly revoke access and remediate, is a complex problem to solve.
