Service Overview

Know Your Real Attack Surface

Most organizations own more assets than they realize. Subsidiaries, acquisitions, forgotten cloud accounts, and shadow IT all expand the attack surface beyond what security teams actively monitor. CyberAlpha's External Attack Surface Assessment combines OSINT, DNS and certificate analytics, and continuous scanning to give you an attacker's view of your organization.

We correlate subdomains, IP ranges, cloud assets, mobile apps, code repositories, leaked credentials, and third-party exposures across the public internet — then rank each asset by exploitability and business impact.

Whether you need a one-time baseline or continuous monitoring, our service finds what you don't know you own and helps you shrink the attack surface before attackers get there first.

Schedule a Consultation

Shadow IT Growth

Business units spin up SaaS and cloud resources faster than security teams can track them.

Forgotten Assets

Legacy subdomains, dev environments, and acquired infrastructure linger on the internet.

Leaked Credentials

Corporate credentials regularly appear in breach dumps, paste sites, and GitHub repos.

Exposed Services

Databases, management consoles, and storage buckets frequently sit on the internet by mistake.

Why It Matters

You Can't Protect What You Don't Know You Own

Shadow IT Growth

Business units spin up SaaS and cloud resources faster than security teams can track them.

Forgotten Assets

Legacy subdomains, dev environments, and acquired infrastructure linger on the internet.

Leaked Credentials

Corporate credentials regularly appear in breach dumps, paste sites, and GitHub repos.

Exposed Services

Databases, management consoles, and storage buckets frequently sit on the internet by mistake.

Subsidiary Exposure

Acquired entities inherit the parent's brand risk without inheriting its security controls.

Third-Party Risk

Partners, suppliers, and contractors host services in your name that you don't directly control.

Our Solutions

Continuous External Surface Intelligence

Discovery, prioritization, and ongoing monitoring of everything an external attacker can see.

Asset Discovery

DNS, certificate transparency, WHOIS, ASN, and cloud correlation to map every public asset.

Subdomain Enumeration

Active and passive subdomain discovery including wildcard and CT-log mining.

Exposed Service Scanning

Fingerprint every open port and service — SSH, RDP, databases, consoles, storage, and more.

Credential Leak Monitoring

Continuous search for exposed credentials on paste sites, breach dumps, GitHub, and dark web.

Shadow IT Detection

Identify unsanctioned SaaS, cloud accounts, and third-party services using your brand.

Continuous Monitoring

Scheduled rediscovery with diff alerts when new assets appear or risky changes occur.

Key Benefits

Reduce Your Attack Surface

01

Complete Asset Inventory

A validated, continuously updated view of every internet-facing asset your organization owns.

02

Faster Exposure Response

Rapid alerting when a new service appears, a port opens, or a certificate exposes a host.

03

Subsidiary & M&A Clarity

Understand inherited exposure from acquisitions before they turn into incidents.

04

Credential Breach Visibility

Catch exposed credentials early so you can rotate before attackers weaponize them.

05

Board-Level Metrics

Clear trend lines showing attack surface growth, shrinkage, and risk over time.

06

Compliance Support

Evidence of continuous monitoring for ISO 27001, SOC 2, and emerging regulatory regimes.

Common Findings

What We Regularly Uncover

Exposed Databases

MongoDB, Elasticsearch, Redis, and PostgreSQL instances open to the internet without auth.

Leaked Credentials

Valid corporate credentials found in public breach compilations, paste sites, and GitHub gists.

Forgotten Subdomains

Dangling DNS records pointing to deprovisioned cloud resources, enabling takeover attacks.

Unmanaged Cloud

Departmental AWS, Azure, or GCP accounts with publicly exposed storage and compute.

Shadow SaaS

Unauthorized SaaS instances (Jira, Confluence, Trello) leaking internal data publicly.

Exposed Git Repos

Internal source code, CI/CD secrets, and infrastructure-as-code exposed on GitHub or GitLab.

Deliverables

Clear, Actionable Intelligence

Executive Summary

Board-level view of attack surface health, trends, and risk posture over time.

Asset Inventory

Structured, queryable inventory of every asset discovered, with owner and risk metadata.

Risk-Ranked Exposures

Findings prioritized by exploitability, business impact, and evidence of active exploitation.

Remediation Playbooks

Ownership-aligned remediation steps mapped to each asset's responsible team.

Continuous Dashboard

Live portal showing discovered assets, active alerts, and remediation progress.

Monthly Reviews

Scheduled reviews covering new exposures, remediation velocity, and strategic recommendations.

Our Approach

A Continuous Discovery Methodology

01

Seed Definition

Define known domains, brands, ASNs, and keywords that act as seeds for discovery.

02

Discovery & Enrichment

Expand seeds across DNS, certificates, WHOIS, cloud APIs, and third-party data sources.

03

Asset Validation

Confirm ownership through active probing, banner analysis, and behavioural correlation.

04

Exposure Analysis

Score each asset for exploitability, data sensitivity, and active exploitation indicators.

05

Continuous Monitoring

Scheduled rediscovery with alerting on new assets, new services, and risky changes.

06

Remediation Support

Work with internal teams to retire, harden, or segment exposed assets and validate fixes.
