Your external attack surface is every digital asset an attacker can find, probe, or exploit without ever touching your internal network. It includes domains, email infrastructure, exposed credentials, unsanctioned applications, and the organizations connected to yours. Leverage Cyber maps all five categories automatically using passive reconnaissance — no scanning, no agents, no disruption to your operations — giving you a complete picture of what attackers see before they act.

Attack Surface Modules

Domains & Subdomains

Discover every domain, subdomain, cloud-hosted property, and acquired asset tied to your organization, including orphaned and forgotten entries.

Email Security

Identify SPF, DKIM, and DMARC misconfigurations that let attackers send email as your brand and bypass spam filters.

Breach Exposure

Surface employee credentials leaked in data breaches, paste sites, and dark web forums before attackers use them against you.

Shadow IT & SaaS

Uncover unauthorized SaaS applications, forgotten cloud instances, and employee-created assets that exist outside your security controls.

Third-Party Risk

Map subsidiaries, acquired entities, key vendors, and technology partners whose exposure extends directly to your attack surface.

Why External Visibility Matters

Attackers do not distinguish between your primary domain and a forgotten subdomain from an acquisition five years ago. They enumerate everything. They correlate leaked credentials from a breach in 2019 with a VPN login page that appeared in a certificate transparency log last month. They find the staging environment a developer spun up in a personal AWS account and left public. Most organizations have no idea these assets exist until something goes wrong. The reality is that most organizations significantly underestimate the size of their external footprint. A typical Leverage Cyber initial assessment uncovers multiple unknown or unmanaged assets — domains that no longer resolve to anything meaningful but still carry live DNS records, SaaS applications authenticated with corporate email addresses, and credentials circulating on forums years after the original breach was disclosed. Each one is a potential entry point. Each one is something an attacker already knows about. External visibility is not optional for organizations that operate at any meaningful scale. Your security posture is only as strong as the weakest asset bearing your name or connected to your identity infrastructure.

How Modules Work Together

The five attack surface modules are not independent checklists — they are interconnected intelligence layers. Leverage Cyber correlates findings across modules to surface chained attack paths that individual checks would miss entirely. Consider a common scenario: a breach exposure finding reveals that a developer’s corporate email address appeared in a credential dump, with a plaintext password. A separate domain discovery finding shows an internal Jenkins CI/CD server exposed on a subdomain. A shadow IT finding identifies that the same developer authenticated a personal GitHub account to your organization’s repositories. Individually, each finding has moderate severity. Together, they form a complete, realistic attack path from public internet to your source code — and Leverage Cyber surfaces that chain explicitly. Other examples of correlated findings include:
  • A leaked credential matched against an exposed partner portal login page
  • A misconfigured SPF record on a subsidiary domain enabling brand impersonation targeting your customers
  • An acquired company’s expired SSL certificate triggering a trust warning that attackers can exploit for phishing
Every high-severity finding in your report is evaluated for cross-module correlation. The findings that appear at the top of your risk prioritization list are there because they represent realistic, multi-step attack scenarios — not just isolated misconfigurations.
Your initial 48-hour assessment covers all five modules simultaneously. You receive a complete cross-correlated picture of your external attack surface from day one, with every finding mapped to an Annual Loss Expectancy (ALE) value in dollars.
