Description

Aster Mail is a complimentary, open-source email service that offers end-to-end encryption for users seeking genuine privacy without cumbersome technical requirements. The encryption process occurs directly on your device, ensuring that our servers never have access to your messages or any associated metadata. Utilizing the widely accepted OpenPGP standard with RSA-4096 keys, Aster ensures that you are not bound to a single provider; your keys can be used seamlessly with GPG, Thunderbird, or any compatible PGP client, and they are easily discoverable via WKD and public key servers. For communications between Aster users, the service employs a Signal-inspired X3DH and Double Ratchet protocol, providing enhanced forward secrecy. Each subscription tier comes with encrypted email capabilities, support for custom domains, free aliases, protection against trackers, and unrestricted access across both web and desktop platforms. The complete codebase is available under the AGPL v3 license on GitHub, allowing for thorough audits, and it features a public warrant canary along with a clear vulnerability disclosure policy. The free tier provides 10 GB of encrypted storage, along with 5 aliases and 1 custom domain. Paid subscriptions begin at just $2.99 per month, and all servers are conveniently located in Germany, ensuring compliance with stringent data protection regulations. Users can feel secure knowing their communications are protected by top-notch encryption standards.

Description

OpenText Core Email Message Privacy provides organizations with a secure method to send emails and attachments, allowing for files up to 100 GB per message, using a web browser or Outlook, all without the need for insecure cloud-sharing solutions. This service employs AES-256 encryption for data at rest, ensuring that messages are uploaded to a highly secure portal; as the sender, you have the ability to establish and manage permissions for actions such as viewing, replying, and forwarding, with the option to revoke access even after the message has been delivered. Recipients receive a secure link, granting them access to the messages through web or mobile platforms without the necessity of installing additional software. Additionally, it supports built-in e-signature capabilities, enabling recipients to insert legally binding signatures within the secure message exchange. Every action—including delivery, opening, downloading, and signing—is tracked in real time and recorded for complete audit purposes. This solution accommodates large file transfers while simplifying infrastructure needs, as it is SaaS-based, requires no additional servers, and seamlessly integrates with single sign-on (SSO) systems. Furthermore, its user-friendly interface ensures that both senders and recipients can navigate the process with ease, enhancing productivity across the organization.
