Critical Security Service

External Attack Surface Testing

Comprehensive assessment of your internet-facing assets to identify vulnerabilities and reduce external attack vectors before attackers find them.

About This Service

Our external attack surface testing provides comprehensive assessment of all internet-facing assets that could be targeted by external attackers. We discover unknown assets, identify vulnerabilities in external services, and help you reduce your attack surface before malicious actors can exploit it. This proactive approach is essential in today's threat landscape where external attacks are the primary vector for most security breaches.

Our Testing Process

A systematic approach to discover, assess, and prioritize external security risks for maximum impact.

1

Asset Discovery & Enumeration

Comprehensive discovery of all internet-facing assets including domains, subdomains, IP ranges, and cloud resources using automated tools and manual techniques.

2

Service & Technology Identification

Identify and fingerprint all external services, applications, and technologies to understand the complete external attack surface and potential entry points.

3

Vulnerability Assessment

Systematic assessment of identified assets for known vulnerabilities, misconfigurations, and security weaknesses using industry-standard scanning tools.

4

Manual Security Testing

Expert manual testing of critical services and applications to identify complex vulnerabilities that automated tools might miss.

5

Risk Analysis & Prioritization

Analyze findings based on exploitability, business impact, and exposure level to prioritize remediation efforts effectively.

6

Reporting & Remediation Guidance

Provide comprehensive documentation with risk ratings, remediation recommendations, and ongoing monitoring suggestions.
