What Caleum does
Caleum a.s. is a Prague-headquartered IT and cybersecurity services company founded in 2009 that serves Czech public administration and mid-to-large private enterprises. Its service portfolio is organized into two core offerings — Kybernetická bezpečnost 360 (comprehensive cybersecurity analysis, strategy, and management) and IT Infrastruktura (enterprise infrastructure design, monitoring, and management) — supported by five service modules covering security consulting, applications, infrastructure, cloud, and maintenance, plus an educational seminars program. The company does not operate a proprietary technology platform; instead, it assembles and operates integrated multi-vendor stacks drawing on partnerships with Cisco, Microsoft, VMware, IBM, Dell EMC, Fortinet, CyberArk, Sophos, Bitdefender, Veeam, Flowmon, LogManager, and other tier-1 OEMs.
Caleum's go-to-market is consultative and sales-led, anchored by a free IT audit offering as the demand-generation entry point. Pricing is not publicly disclosed and contracts are negotiated per engagement. The customer base spans Czech central-government ministries (Finance, Agriculture, Education), state-owned enterprises (Czech Railways, CD Cargo, CD Telematika), large hospitals and clinical institutes (FN Olomouc, FN Hradec, Thomayerova, Nemocnice na Homolce, IKEM), environmental agencies (KRNAP, Nature Protection Agency, Environmental Fund), and private firms (Akcenta, Mountfield). All operations are run from a single Prague 3 office with a 14-person team, and the company operates exclusively in the Czech market with no disclosed cross-border presence.
Revenue is generated entirely through professional services — cybersecurity analysis, IT infrastructure implementation and management, monitoring, and maintenance — with no disclosed product, subscription, or licensing line. The firm maintains ISO 27001, ISO 14001, and ISO 9001 certifications, which function as procurement prerequisites for regulated Czech public-sector and healthcare buyers. Ownership is private and not disclosed; there are no recorded funding rounds, acquisitions, or leadership changes in the source data.
