Today's Deep-Dive: schleuder
In this episode, we take a deep dive into Schleuder, an open-source encrypted mailing list manager designed for organizations that need secure group communication without surrendering control to proprietary platforms. Starting with the basic problem of who really holds the keys to your organization’s most sensitive communications, we explore how Schleuder uses OpenPGP encryption to make secure mailing lists manageable, even in environments where legal, regulatory, and compliance requirements make privacy and auditability non-negotiable.
Along the way, we unpack how Schleuder works under the hood, from public and private key encryption to its role as a secure gateway that can translate between encrypted internal conversations and unencrypted external contacts. The episode also looks at the practical realities of deploying and maintaining open-source security tools, including entropy, server dependencies, command-line and web-based administration, and the open-source community effort required to keep projects like this alive. More than just a technical walkthrough, this is a conversation about digital sovereignty, infrastructure ownership, and what it means to truly control the keys to your own communication systems.
Gain digital sovereignty now and save costs
Let’s have a look at your digital challenges together. What tools are you currently using? Are your processes optimal? How is the state of backups and security updates?
Digital Souvereignty is easily achived with Open Source software (which usually cost way less, too). Our division Safeserver offers hosting, operation and maintenance for countless Free and Open Source tools.
