Wat is een cybersecurity audit?
Een cybersecurity audit is een uitgebreide beoordeling van alle digitale beveiligingsmaatregelen van uw organisatie. De audit omvat netwerk-, endpoint-, applicatie- en databeveiliging, alsook beleid, processen en bewustwording.
In tegenstelling tot een penetratietest die zich richt op het vinden van specifieke kwetsbaarheden, beoordeelt een cybersecurity audit het volledige beveiligingslandschap vanuit een holistisch perspectief.
Waarom is een cybersecurity audit belangrijk?
Cyberdreigingen worden steeds geavanceerder en de potentiële schade van een succesvolle aanval groeit. Een cybersecurity audit identificeert zwakke punten in uw verdediging voordat aanvallers dit doen.
Regelgeving zoals NIS2, DORA en de AVG vereisen adequate cyberbeveiligingsmaatregelen. Een cybersecurity audit geeft inzicht in uw compliance-status en prioriteert verbeteracties.
Voor wie is een cybersecurity audit?
Middelgrote bedrijven
Organisaties die groeien en hun beveiliging willen professionaliseren.
Kritieke infrastructuur
Organisaties in sectoren zoals energie, water en telecom die essentiële diensten leveren.
Na een incident
Organisaties die na een beveiligingsincident hun beveiliging willen verbeteren.
Bestuurlijk niveau
Directies die inzicht willen in de cybersecurity-status en risico's van hun organisatie.
Hoe verloopt een cybersecurity audit?
Scope en kader
Bepaal de scope en het toetsingskader (bijv. NIST CSF, CIS Controls, ISO 27001).

Vulnerability scan
Geautomatiseerde scan van netwerk en systemen om bekende kwetsbaarheden te identificeren.

Frequently asked questions about Cybersecurity Audits
Wat is het verschil tussen een cybersecurity audit en een pentest?

Hoe lang duurt een cybersecurity audit?
Gemiddeld 2-6 weken afhankelijk van de omvang van de organisatie en de diepgang van de audit.
Welk framework wordt gebruikt?
Veelgebruikte frameworks zijn NIST Cybersecurity Framework, CIS Controls, ISO 27001 en het NCSC-cybersecurityframework.
