What Is a Vulnerability Assessment?
A Vulnerability Assessment is a systematic review of systems, applications, devices and networks to identify security weaknesses that could be exploited by cyber criminals.
The goal is to discover vulnerabilities before attackers do, allowing organisations to reduce cyber risk, improve security and strengthen their overall cyber resilience.

Vulnerability Assessment Explained
Every business system contains potential weaknesses. These weaknesses may result from missing security updates, weak configurations, exposed services, excessive permissions or outdated software.
A vulnerability assessment identifies these issues and prioritises them based on risk, helping organisations address the most serious threats first.
Think of a vulnerability assessment as a health check for your cyber security. It helps identify weaknesses before they become security incidents.
What Does a Vulnerability Assessment Look For?
Missing Security Updates
Outdated software and operating systems that contain known vulnerabilities.
Weak Configurations
Systems configured in ways that increase security risks.
Open Ports & Services
Exposed services that could be targeted by attackers.
Authentication Weaknesses
Poor password controls and missing Multi-Factor Authentication.
Privilege Risks
Excessive permissions and administrator account exposure.
Cloud Security Issues
Weaknesses affecting Microsoft 365 and cloud platforms.

Most organisations should perform vulnerability assessments at least annually and after significant infrastructure changes.
Does a vulnerability assessment include Microsoft 365?
Yes. Modern assessments frequently include Microsoft 365 security reviews and cloud configuration assessments.
What is the difference between a vulnerability assessment and a cyber security audit?
