DNS Filtering Netherlands – Complete Guide

 

Did you know that the majority of cyber attacks begin because employees unknowingly visit an insecure Web site? A single click can lead to viruses, ransomware or data breaches. SMEs in the Netherlands are especially vulnerable to this.

With DNS filtering, you can block these threats even before they reach your network. This reduces the chances of employees accidentally opening malicious websites. At ALTA-ICT, we provide secure, unobtrusive DNS filtering, so your team can continue working undisturbed – without the risk of viruses or downtime.

In this guide, you will learn what DNS filtering is, how to implement it, what mistakes to avoid and how ALTA-ICT can support your business in doing so.

What is DNS filtering and why is it crucial for Dutch companies?

DNS filtering blocks dangerous websites at the network or device level. This prevents employees from accidentally visiting harmful content. The benefits are:

  • Preventing malware and phishing attacks.
  • Protection against data breaches and downtime.
  • Enhanced network security without complicated settings.

For Dutch companies, this is especially important because of AVG compliance and the increase in cybercrime targeting SMEs.

 

Implementing DNS filtering in the Netherlands – Step-by-Step

  1. Conduct risk analysis – Identify current threats.
  2. Choice of DNS filter solution – Depending on company size and industry.
  3. Installation and configuration – According to Dutch privacy legislation (AVG).
  4. Employee training – Raise awareness about safe Internet use.
  5. Monitoring and maintenance – Regular updates and reports.

At ALTA-ICT, we take this entire process off your hands, with fully AVG-proof solutions and 24/7 monitoring.
