Qualys

Qualys is a cybersecurity company founded in 1999 that delivers a cloud-based, unified platform for managing cyber risk. Its Enterprise TruRisk Platform combines asset management, vulnerability detection, compliance and threat protection, continuously monitoring on-premises infrastructure, cloud environments, containers and mobile devices to produce real-time risk insight and prioritisation. The company pioneered the security-as-a-service delivery model before the term SaaS was in common use.

For engineers, the work sits at the intersection of large-scale data collection, real-time analytics and risk quantification. The technical scope spans vulnerability management and detection, cloud, container and mobile device security, on-premises security monitoring, and cyber risk prioritisation. The platform is designed to surface what actually matters rather than to present raw findings: it is reported to deliver insights with more than 99.99966% accuracy, a figure the company treats as central to its approach to data quality.

Qualys reports that more than 10,000 organisations across upwards of 130 countries use the platform, with a majority of the Forbes Global 100 among its customers, alongside small and mid-sized businesses. Its stated philosophy favours a single unified platform over a set of disconnected point solutions, and it frames its purpose as helping security teams move from reactive response toward advising the business in business terms.
