Czech cybersecurity firm Logmanager sold to Danish Guardsix

The Brno-based company Logmanager, a developer of a cybersecurity analytics platform, is joining Denmark's Guardsix. The deal's value, estimated by CzechCrunch, could reach the low hundreds of millions of crowns, and for Logmanager's director Jiří Tobola it's far from his first successful business exit.

Logmanager was founded in 2014 and today has around 30 employees in Brno and Prague, serving 400 clients across the region. The company develops its own platform for managing and analyzing so-called logs — digital records generated by servers, applications, networks and security systems. This helps businesses respond faster to cyber threats, fix outages and meet regulatory requirements.

Logmanager representatives declined to disclose the exact deal value, but the company has grown rapidly in recent years — by its own figures, revenue has nearly quadrupled over three years, and this year the firm expects turnover to exceed 130 million crowns.

“Logmanager is strong in Central Europe, Guardsix is strong in Western Europe. So it makes sense to join forces and build something bigger,” says Tobola. According to him, the company's current leadership is reinvesting a significant part of its stake into Guardsix and will keep actively taking part in developing the merged business.

Before the deal, Logmanager was owned by Petr Skořepa, Filip Weber, Jiří Tobola himself, and Japan's Orizon Systems, which joined as a shareholder in 2024 after previously acting as a sales partner.

Guardsix CEO Mikkel Drucker noted that Logmanager “solved a real problem for a customer segment that has historically received little attention.” After the integration, the Logmanager brand and its team will remain in place, and all client contracts will stay unchanged.

This isn't Tobola's first high-profile business exit. In 2007, together with partners, he launched the university spin-off Flowmon Networks, which 14 years later went through a double exit in the US: first bought by Kemp, then by the much larger Progress Software. Part of Logmanager's current team — Luboš Lunter, Artur Kane and Jan Kalabus — also came from Flowmon. In addition, in 2020 Tobola took part in selling another Flowmon spin-off, Netscope Technologies, which came under the control of America's Intel.

According to Tobola, what matters isn't just the size of the deal but also who the company is sold to: “It's great that we're selling Logmanager not to America, but to a European company. Our shared goal is to build a European leader in cybersecurity — this is an area where the old continent has some catching up to do compared to the US, Israel or China.”
