Zero Trust – Smart IT security for SMEs.

Cyber attacks on Dutch SMEs are increasing at double-digit rates every year. According to CBS, nearly 1 in 3 companies faced a digital break-in attempt in 2024. Yet many organizations still rely on classic security models where employees and systems are automatically granted access once they are “inside.

Zero Trust fundamentally changes this. The principle is simple but powerful: trust no one, always verify. No default access for everyone, but smart controls that determine: who is allowed what and when?

At ALTA-ICT, we help Dutch SMEs to seamlessly implement Zero Trust in their Microsoft environment. Thanks to our ISO27001 and NEN7510 certifications, you can be sure that your organization is not only technically highly secured, but also complies with all relevant Dutch laws and regulations (AVG, BIO, sector standards).
