Overview

We map what your organization exposes to the internet, domains, subdomains, services, and forgotten systems, and analyze the exposure, shadow IT, and leaked data attackers use as a way in, then give you clear steps to reduce it.

Who it's for

Organizations that want to reduce external exposure before it's exploited.

Our perspective

Understanding Attack Surface Assessments

Your attack surface is everything an outsider can reach and probe without any inside access: domains, subdomains, exposed services, cloud endpoints, forgotten hosts, and the data about your organization that lives on the public internet. Attackers begin every campaign here, quietly mapping what you expose before they ever send an exploit. An attack surface assessment does the same reconnaissance from the outside in, so you see your organization exactly as an adversary sees it: as a set of entry points, not an org chart.

The dangerous exposures are usually the ones nobody remembers. A staging server left running, a subdomain pointing at a decommissioned service, an old marketing microsite, a cloud bucket spun up for a one-off project. These forgotten and shadow IT assets sit outside patching and monitoring, and they are frequently how attackers get in. We enumerate them systematically, correlate them to your organization, and flag the ones that represent real risk rather than harmless noise.

Good assessment goes beyond listing assets. We analyze each exposure for weak configuration and known vulnerabilities, and we search public and criminal sources for leaked credentials and sensitive data tied to your domains and people. You receive a prioritized reduction plan: what to decommission, what to reconfigure, and what to monitor, ordered by exploitability and impact so remediation effort goes where it actually lowers risk.

What we test

What we map and analyze

Domains & Subdomains

Discover all domains, subdomains, and DNS records tied to your organization.

Exposed Services & Ports

Identify internet-facing services, ports, and technologies in use.

Shadow IT & Forgotten Assets

Surface unmanaged systems, dev/staging, and abandoned infrastructure.

Cloud & SaaS Exposure

Find exposed cloud storage, apps, and misconfigurations.

Certificate & DNS Hygiene

Review TLS certificates, expiries, and DNS misconfigurations.

Credential & Data Leakage

Detect exposed credentials and data tied to your brand.

Third-Party & Supply-Chain Exposure

Map exposure introduced by vendors and integrations.

Change & Drift Monitoring

Track how your attack surface changes over time.

Our approach

How we deliver Attack Surface Assessments

01

Footprint mapping

02

Exposure analysis

Identify shadow IT, leaked credentials, and misconfigurations.

03

Risk prioritization

Rank exposures by exploitability and business impact.

04

Reduction guidance

Clear steps to shrink and monitor the attack surface.

Where this fits

Common situations we are called in for

01

Unknown or sprawling estate

An organization that has grown through projects, teams, and acquisitions no longer has a reliable inventory of what it exposes to the internet.

02

Post-acquisition integration

A company needs to understand the full external footprint of an acquired business before connecting it to the corporate network.

03

Recurring external exposure baseline

Security leadership wants a periodic outside-in view to catch new exposures and shadow IT before attackers find them first.

04

After a near miss or scare

Following an alert, a leaked credential, or an industry breach, an organization wants to know what else it is exposing that it has forgotten about.

FAQ

Common questions

What's in scope?

Your internet-facing assets, domains, subdomains, services, and forgotten or shadow IT systems.

Do you exploit findings?

This is discovery and exposure analysis; exploitation is covered under VAPT or red teaming.

How often should we run it?

Attack surfaces change constantly, so periodic or continuous monitoring is recommended.

Will you find leaked credentials?

Yes, we analyze exposure and leaked data attackers could use as a way in.

Let's scope your attack surface assessments engagement.

Practitioner-led delivery, platform-backed evidence, and retest validation included at no added cost.
