Slovak IT integrator JKC has been a long-standing supplier of Kerio technologies. With growing pressure on cybersecurity, it sought a top-tier solution that would enable it to offer managed services (MSP) to its customers, primarily in the public sector, which is being forced to improve its protection by increasingly sophisticated attacks and tightening regulations.

JKC built its offering on the N-able portfolio from ZEBRA SYSTEMS: N-sight for IT infrastructure monitoring, Cove Data Protection for backup as a service, N-able EDR (SentinelOne) and MDR (Adlumin) for cybersecurity. For a public administration customer, it combines these with GFI KerioConnect, KerioControl, the AST SIEM tool, and Impossible Cloud storage.

The N-able portfolio became the foundation of JKC's transition to a certified managed services model, and Cove now backs up data for a number of Slovak organizations. For its system integration capabilities, JKC received the “Best Integrator” award for 2024 from ZEBRA SYSTEMS and the international Customer Success Champion 2025 award from GFI.

D.A.S. legal expenses insurer needs to find exact wording in email communications even 10 years back, typically due to ongoing court proceedings. More than 300,000 emails with approximately 90 GB of data pass through the company every quarter. Previous storage in backed-up PST files did not guarantee recovery of all emails.

The company deployed GFI Archiver, which uses journaling to store original emails and files in a central repository resistant to unauthorized tampering, separate from the mail server.

3 TB of email is archived exactly as it was received or sent from the company, serving as verifiable evidence of communication. Full-text search finds an email by date, insurance policy number, or claim number almost instantly, and accidentally deleted messages can be restored to users.

The license was provided to the school by GFI Software.

Thanks to the intuitive interface, students quickly understand how to work with a firewall and gain knowledge of modern security practices such as two-factor authentication. They can then quickly find their way around in an organization that uses Kerio Control.

Slovakia’s largest food wholesaler operated an older mail system without shared calendars or mobile access, while processing 6,400 emails totaling nearly 2 GB every day. It was looking for stable on-premise email with full control over its data—it did not want a cloud solution.

Based on the recommendation of its IT partner RD-System Slovakia, it deployed GFI KerioConnect integrated with Microsoft Outlook, providing email and calendars on mobile devices, antivirus and antispam protection, and email archiving.

The solution is relied on by 320 users. The company gained secure on-premise email which, at the time of deployment, offered functionality comparable to Microsoft Exchange at significantly lower costs, more convenient email management thanks to calendars, and better security.
