The avm ken 4 mail server was once a popular solution for small and medium-sized companies looking for a simple way to combine email, internet access and user administration in one system. However, like many IT systems from the early 2000s, KEN 4 is now technologically outdated - and now poses a security and efficiency risk.

The GRAEF Group supports companies in making the transition from outdated mail servers such as avm ken 4 to modern, GDPR-compliant communication solutions smoothly.

Why AVM KEN 4 is no longer up to date today

AVM KEN 4 once offered functions such as e-mail management, Internet gateway and simple user rights management - ideal for local networks of small companies. However, this software has not been actively developed or supported for years.

The result:

❌ No more security updates or support
⚠️ Outdated encryption standards (e.g. SSL instead of TLS 1.3)
📧 Limited compatibility with modern operating systems
🧩 No integration into current cloud or Exchange environments

Companies that still rely on avm ken 4 not only risk downtime and data loss, but also violations of the General Data Protection Regulation (GDPR).

Switching to modern mail servers - secure, efficient and future-proof

The GRAEF Group advises companies comprehensively on migrating from old mail servers such as AVM KEN 4 to new, secure and scalable systems.
Our IT experts develop individual migration concepts and rely on proven solutions such as:

Microsoft 365 Exchange Online - ideal for companies with a cloud focus
On-premise mail server with security layers - for industries with special data protection requirements
Hybrid systems - local control combined with cloud flexibility

We ensure:
✅ Secure data migration without loss
✅ Set up modern encryption and backup mechanisms
✅ Integration of existing users and authorizations
✅ Minimal downtime during the changeover

The advantages of modern mail servers

An up-to-date e-mail system not only replaces old software, but also increases productivity:

💡 Greater security
Active updates, modern authentication (MFA) and spam filters provide reliable protection against cyber attacks.

📈 Better performance
Cloud-based systems enable fast access, even on the move and across different locations.

🔗 Integration into existing IT systems
Seamless connection with CRM, ERP and document management systems.

🌍 S ustainability & energy efficiency

How the GRAEF Group helps companies make the switch

Our team of experts first analyzes the current status of the IT infrastructure and checks which data and systems are still linked to avm ken 4. We then plan a customized migration that securely transfers all emails, contacts and calendar data to a new system.

We not only take care of the technical implementation, but also provide training for employees and ongoing support after the changeover.
