Top IT Companies in Belgium
Approximately 198,427 real businesses classified under Information and Communication in Belgium, with officer, shareholder and beneficial ownership records sourced directly from official government registries.
Approximately 198,427 real businesses operate in the Information and Communication sector across Belgium. Software and telecom companies are the sector most likely to have four holding-company layers before you reach a real person — and it is rarely for tax reasons alone. Staged venture-capital and private-equity investment rounds, plus standard tax-efficient group structuring, both push ownership chains further here than in almost any other sector. The sector covers software publishing, IT services, telecom network operation, broadcasting, and publishing, and beneficial-ownership resolution is disproportionately relevant precisely because of that depth.
111 companies in this sector are indexed on Zavia so far, part of a continually growing dataset.
Beneficial-ownership and registration rules for Information and Communication companies in Belgium follow the same national framework as every other sector there.

Analysis
What this data actually tells you
Information and Communication in Belgium operates under NIS2 as transposed by the Law of 26 April 2024, with its substantive cybersecurity risk-management and incident-reporting obligations applicable from 18 October 2024. The Centre for Cybersecurity Belgium (CCB) serves as the national cybersecurity authority and national CSIRT, alongside relevant sectoral authorities, and recognises CyberFundamentals (CyFun) and ISO/IEC 27001 as reference frameworks for demonstrating compliance. By late November 2025, Belgium had already registered 1,500 essential entities and 2,500 important entities under the law.
18 April 2026 is a specific, critical compliance milestone: essential entities must by then be able to demonstrate they’re effectively implementing cybersecurity risk-management measures via a recognised pathway. Scope itself depends on two criteria together — operating in one of the 18 sectors listed in NIS2’s annexes, and meeting a size threshold of at least 50 employees or €10 million in annual turnover or balance sheet. For verification, a Belgian IT or digital-infrastructure counterparty’s NIS2 status depends on checking both criteria, and its registration and compliance-pathway status with the CCB is a distinct, checkable fact from general company registration.

Who uses Belgium information and communication ownership data
The three checks this sector's data is most often run for.
NIS2 essential/important-entity screening
Belgium transposed NIS2 via the Law of 26 April 2024, applicable from 18 October 2024, with CCB (Centre for Cybersecurity Belgium) as the national authority. By late November 2025, Belgium had already registered 1,500 essential entities and 2,500 important entities — a real, checkable scale of compliance already underway.
18 April 2026 essential-entity deadline
18 April 2026 is a critical milestone: essential entities must be able to demonstrate they’re effectively implementing cybersecurity risk-management measures following a recognised compliance pathway — CyberFundamentals (CyFun) or ISO/IEC 27001 are the recognised reference frameworks.
Size-and-sector scope check
NIS2 scope in Belgium depends on two criteria together: operating in one of 18 listed sectors, and meeting a size threshold of at least 50 employees or €10 million in turnover/balance sheet — a company can be in a covered sector and still fall below the size threshold, or vice versa.
