Vulnerability Assessment Providers

Vulnerability assessment is a systematic process of identifying, quantifying, and prioritising security vulnerabilities across an organisation's IT infrastructure, applications, and networks. Unlike penetration testing, which involves active exploitation, vulnerability assessments focus on identifying and cataloguing known vulnerabilities using automated scanning tools combined with manual verification to reduce false positives.

Assessments cover operating systems, network devices, web applications, databases, and cloud resources, producing a prioritised list of vulnerabilities rated by severity, exploitability, and business impact. Vulnerability assessments provide broad coverage across the attack surface and are an efficient way to identify low-hanging fruit and maintain ongoing visibility into security posture.

Many organisations use vulnerability assessments as a complement to penetration testing, running regular assessments (monthly or quarterly) between annual pen tests. Vulnerability assessments are required by compliance frameworks including PCI DSS (quarterly scans), ISO 27001, SOC 2, HIPAA, and Cyber Essentials. Managed vulnerability assessment services provide continuous monitoring and reporting, helping organisations maintain compliance and respond quickly to newly disclosed vulnerabilities.
