Cyllium

What Cyllium does

Cyllium is a Slovak cybersecurity and IT services group headquartered in Bratislava, organized across three wholly-owned entities — auditori.it (audit), Cyllium SK (market-facing operations), and Cyllium IT (technology delivery). Its portfolio is built around five service pillars: Audit Services (cybersecurity audits, ISO 27001, NIS2, DORA, GAP analysis), Expert Services (ISMS implementation, risk management, AI governance and AI Act compliance), Technology Services (implementation and management of EDR/XDR, SIEM, IAM, PAM, MFA and the proprietary Cyllinder Program), the external Manažér KB service (a tiered subscription providing certified cybersecurity manager coverage under Slovak law 69/2018, deployable within 14 days), and Strategic Management (C-level IT and security leadership, including full outsourcing).

The company serves regulated organizations in Slovakia — operators of essential services (PZS), digital service providers, public administration bodies, and entities in financial services, healthcare, and energy — that must comply with Slovak cybersecurity law 69/2018, the NIS2 transposition (Law 366/2024), and Decrees 226/2025 and 227/2025. Revenue is generated through three streams: recurring Manažér KB subscriptions (monthly Minimal/Standard/Optimal tiers), per-engagement audit and compliance professional services, and project-based security technology implementation. Pricing is quote-based and not publicly disclosed; a free initial consultation serves as the primary customer acquisition entry point. Distribution is entirely direct B2B — there are no self-service, marketplace, or reseller channels.

The technical team is small (1–10 employees) but credentialed: six certified cybersecurity managers (MKB) and two certified KB auditors hold 15+ international certifications (CISA, CISM, CISSP, CEH, CDPSE, GICSP, CIA, PCI QSA). Cyllium has completed 200+ projects across 8 industries over 22+ years of operation. Marketing is content-driven, anchored by a Slovak-language weekly blog, a GDPR-compliant newsletter, and threat intelligence content sourced under an editorial partnership with Check Point Research. The company is privately held with no disclosed external investors, parent, or public listing.

Others

• Check Point Software: Global cybersecurity vendor and Cyllium's threat intelligence partner; provides the underlying security platforms (firewalls, EDR/XDR) that Cyllium's Technology Services pillar implements and manages.

Broad incumbents

• ESET: Slovak-headquartered global cybersecurity vendor with a much broader product portfolio and scale. Comparable as a Slovak-rooted cybersecurity brand but operates as a software vendor rather than a managed services firm.
• Asseco Central Europe: Large Central European IT services group with cybersecurity, audit, and compliance offerings serving regulated clients across Slovakia and the wider CEE region — broader portfolio and significantly larger scale than Cyllium.
• KPMG Slovakia: Big 4 advisory firm with a cybersecurity practice in Slovakia covering NIS2, ISO 27001, and risk advisory — competes for the same regulated-entity audit and compliance engagements as Cyllium at the higher end of the market.
• Deloitte Slovakia: Big 4 firm with a cybersecurity and risk advisory practice in Slovakia, providing audit, compliance, and managed security services to large regulated enterprises — a broader incumbent competitor to Cyllium's advisory and managed offerings.
• PwC Slovakia: Big 4 firm with cybersecurity, risk, and compliance capabilities serving Slovak regulated entities — overlaps with Cyllium's audit and advisory services for the largest enterprise and public-sector clients.

Emerging players

• Safetica: Czech/Slovak-headquartered data protection and insider threat software vendor with overlapping customer base in CEE regulated markets — adjacent rather than directly competing in managed services.

Direct peers

• Binary Confidence: Slovak cybersecurity services firm providing penetration testing, security audits, and compliance consulting to regulated entities in Slovakia, comparable in scale and service mix to Cyllium.
• Aliter Technologies: Slovak IT and cybersecurity firm offering security solutions, consulting, and managed services to government and enterprise clients across Slovakia, overlapping directly with Cyllium's audit and managed security offerings.
• Soitron: Slovak-headquartered IT services and solutions provider with a security practice covering managed services, infrastructure, and consulting. Competes directly with Cyllium in the Slovak enterprise IT and cybersecurity services market.
