One contact – one platform – full digital sovereignty
What is email groupware?
A groupware combines everything teams need day to day – email, calendars, contacts, tasks and notes – in one seamless solution. Instead of maintaining several programs, everyone accesses the same shared data. Changes to appointments, addresses or tasks are immediately synchronised across all devices and users.
The real added value lies in sharing: shared calendars for easy planning, shared contacts for the whole company and public folders in which knowledge is stored centrally. A good groupware synchronises reliably between server, browser and mobile device so that your team is always working with the latest information.
Kerio groupware turns individual mailboxes into a central hub for corporate communication.
Kerio Connect is the modern, central email platform for everyday collaboration.
What makes Kerio Connect better?
Kerio Connect excels where large platforms often become too complex: with clarity, stability and fair value for money. The solution runs lean and reliably without time-consuming administration – ideal for small and medium-sized businesses that want modern groupware without the complexity and error-proneness of Microsoft Exchange.
Kerio Connect is cross-platform and therefore compatible with macOS, Windows and Linux as well as with common mail clients such as Apple Mail, Outlook or Thunderbird. Thanks to ActiveSync, smartphones and tablets are connected directly, so your emails, appointments and contacts stay up to date everywhere.
The result: a powerful yet easy-to-maintain solution that makes everyday work noticeably easier.
Simple and stable – the alternative to Exchange
Why should we use Kerio Connect?
Where your emails are stored determines who may access them.
With local hosting on your own on-premises servers, all data remains entirely within your company – protected from access by foreign authorities, for example under the US CLOUD Act.
For businesses, law firms, fiduciaries, medical practices and organisations handling sensitive information in particular, this control is a decisive factor for security and trust.
We not only help you acquire the right Kerio Connect licence, but also support you in setting up your server environment and in day-to-day operation. On request, we integrate your solution into walkingtoweb's backup infrastructure or complement it with powerful mail gateways for additional protection against spam, malware and phishing.
The result is a secure, stable and professionally supported email infrastructure – entirely under your control.
As a secure, high-performance alternative to Exchange and other email servers, Kerio Connect has been the best email groupware solution for businesses for many years.
What can the mail server do?
Kerio Connect is far more than a mail server. It combines email, calendars, contacts, tasks, notes and shared folders in one integrated environment, synchronised centrally across all devices.
Kerio Connect groupware uses open standards (IMAP, SMTP, POP3, CalDAV, CardDAV) and synchronises mobile devices via ActiveSync. This lets you connect Apple Mail, Outlook, Thunderbird or native apps on iOS and Android without any problems. Alternatively, Kerio Webmail is available in the browser, with no installation required.
Security is ensured by TLS encryption, spam and virus protection, filters, archiving, automatic backups and central, intuitive administration.
Kerio Connect is a mature and dependable email groupware that serves as a complete communication centre for email, calendars and tasks.
Why is digital sovereignty so important?
Email is the memory of a business – contracts, quotations, internal arrangements and customer data flow through it every day. Anyone who gives up control over this communication loses a piece of entrepreneurial freedom. Digital sovereignty means that you decide where your data is stored, who may access it and under which rules it is processed.
Many international providers store data outside Europe, under foreign laws and with potential use for algorithms or advertising. This makes it impossible for you to meet your compliance obligations and applicable laws.
Sovereignty means: open standards instead of dependency, clear locations instead of a black box, data protection instead of data exploitation. Especially with email, this independence is not a luxury but a prerequisite for trust and responsibility towards your customers.
Independence starts with your email.
