Attack Surface Monitoring

What Is Hanging Outside Your Digital Front Door?

Modern infrastructure changes constantly. New services are deployed, test environments appear, integrations are added, and temporary solutions are created to move projects forward. Over time, this leads to shadow IT — systems, domains, and services that exist outside normal visibility.

A subdomain created for a short-lived project. A development environment that was never removed. An API endpoint still reachable from the internet. A server with a port exposed during troubleshooting that was never closed again.

Individually these seem minor, but together they form an expanding external footprint that is easy to overlook.

For attackers, these forgotten or unmanaged assets are often the easiest entry points — not because they are critical systems, but because nobody is actively watching them.

Attack Surface Monitoring continuously maps your external digital presence. Not as a one-time inventory, but as an ongoing process — because your attack surface evolves every time something new is deployed, changed, or left behind.

What Does It Actually Do?

We continuously look at what is publicly visible and reachable on behalf of your organisation: domains, subdomains, IP addresses, accessible services, and their configuration. That produces two kinds of insight.

First: what you already knew about, but that needs attention. Known systems running outdated software, misconfigured security settings, or unnecessary services that would be better closed off.

Second: what you did not know was there. Assets that have grown outside your managed environment, exposed environments sitting in a cloud account somewhere, or leaks via repositories and external sources that contain your organisation’s name or domains.

How Does This Differ from an OSINT Investigation?

An OSINT investigation is a one-time, manual analysis — we actively go looking for everything findable about your organisation, from technical details to employee information and dark web mentions.

Attack Surface Monitoring is not an investigation but a service. It runs in the background, flags changes, and gives you a current picture without requiring a new assignment each time. The two work well together: an OSINT investigation as a starting point, monitoring to keep the picture up to date.

What Does It Deliver?

You receive periodic overviews of your external attack surface, including new findings, changed situations, and a prioritisation by risk level. Not a collection of standalone reports, but an ongoing view of what your external profile looks like right now — and how it develops over time.
