Mailfence allows you to organize your life through powerful productivity tools such as Mailfence Calendar, Mailfence Documents, Mailfence Contacts, Mailfence Groups, Mailfence Chat and Mailfence Polls.

Beeble

We have created a secure Email and Cloud storage, putting privacy at the forefront. From the very beginning, Beeble platform has been created in such a way that only the user has the access to his personal information. The information in our servers is not stored, sent or processed in an open form. We do not have access to the users’ passwords and encryption keys. All data is encrypted on the client’s device and then transferred to us. This means that neither we, nor any third party can decrypt the information we store and access the contents of letters or files without the user’s knowledge.

Mailock

Mailock is a secure email (outbound email security) and delivery-evidence solution that helps organisations send encrypted messages and files via standard email while recording key delivery and access events for governance and compliance use cases. Mailock sits in the secure communications category, supporting teams that need to exchange sensitive or regulated information with customers, clients, patients, or partners without moving them into a separate portal-first workflow. Typical users include compliance, risk, customer communications, IT, and service teams in regulated and privacy-sensitive sectors such as financial services, insurance, legal, healthcare, and utilities. Organisations use Mailock to protect information in transit and to control access to message content and attachments after sending. It supports use cases such as sending statements and disclosures, claims and policy documents, client instructions and identifiers, invoices and contracts, case files, and other communications where confidentiality, recipient assurance, and evidence of delivery or access may be required for oversight. Mailock is also used to improve auditability of email-based delivery by capturing records across the message lifecycle (for example, dispatch, delivery to inbox, and access to secured content), which can be referenced when delivery is later queried. Key capabilities and value propositions include: Encryption and access control: Encrypts email content and attachments, with configurable access policies (such as time limits or withdrawal of access) to manage post-send exposure. Recipient verification options: Provides configurable identity or recipient-assurance steps (for example, knowledge-based challenges) when higher assurance is needed. Delivery and access records: Creates a tracked record of delivery lifecycle events and recipient interaction to support internal controls, audit, and dispute handling. Workflow and deployment options: Supports sending from common email environments (including Microsoft Outlook via add-in) and web-based sending for users who do not use Outlook. Administration and governance: Offers organisational management features such as policy controls, user administration, and reporting to help standardise secure delivery practices across teams.
