Key takeaway
Asset discovery is only the start; confirm ownership, prioritize risk and verify remediation again.
Find known and unknown assets
The attack surface is the set of entry points that could expose systems, data or services. Inventory websites, APIs, cloud storage, email systems, IoT, remote endpoints and third-party connections. Compare external reconnaissance and OSINT with internal cloud records to find forgotten domains, test environments and legacy services.
Prioritize findings by business risk
Record each asset’s owner, purpose, internet exposure, data and dependencies. An open port or vulnerability scan is a risk signal, not proof of compromise. Weigh exposure, evidence of exploitation, asset importance and remediation effort together, and examine short paths to critical systems.
Find and manage shadow IT
Shadow IT means services, software and devices used without the IT department’s approval. When approvals are slow or existing tools do not fit the work, employees may use personal SaaS accounts, cloud storage and devices. Data location, access and backup status may then be unclear. Review network inventory, cloud accounts, spending and access records; ask employees what they need and provide a suitable approved option.
Repeat the cycle and verify fixes
Cloud migration, new partners, hiring and software releases change the asset map. Repeat discovery, assign an owner to each new finding, track remediation and verify closure with another scan or configuration check. Before automatically blocking unapproved software, assess the impact, data risk and work need.
