FAQ Cybersecurity
-
-
A strong cybersecurity strategy prevents data breaches, business disruption, and reputational damage. As threats grow more sophisticated, businesses are also legally obligated to protect sensitive data under GDPR and NIS2.
-
Phishing is a form of fraud via email, SMS, or phone where attackers pretend to be trustworthy parties to steal your personal or business data. Watch out for suspicious links, unusual senders, spelling errors, and urgent messages. Never click on links without verifying and report suspicious messages.
-
Prevent ransomware with regular updates, endpoint protection, backups, and cybersecurity awareness training for staff. A good access policy and network segmentation also greatly reduce risks.
-
Cybersecurity (the technical approach) focuses on protecting systems using tools like firewalls and antivirus. Cyber safety is broader — it includes human behaviour, processes, and policies that keep the entire organisation digitally safe.
-
NIS2 is a European directive that imposes stricter cybersecurity obligations on essential and important entities, such as telecom, energy, and healthcare providers. It includes riskmanagement, incident reporting, and cross-sector collaboration. Proximus NXT helps you stay compliant.
