Organizations may expose more assets to the internet than they realize. Domains, subdomains, VPN gateways, cloud services, old portals, test systems, certificates, APIs, and third-party hosted systems can remain visible after projects change or teams move on.

Cryptika performs external attack surface assessment to help organizations understand what is visible from outside, which assets appear unmanaged or risky, and which exposures should be corrected before attackers or auditors find them.

Why Organizations Need It

Attackers often begin with external discovery. If the organization does not maintain a clear view of its internet-facing assets, it may miss vulnerable services, forgotten portals, weak DNS records, exposed management interfaces, or third-party systems representing the brand.

An external attack surface assessment supports asset governance, vulnerability management, cloud security, third-party oversight, and executive visibility over internet exposure.

Methodology Basis

The assessment may use external reconnaissance practices, CIS Controls, NIST CSF 2.0, MITRE ATT&CK awareness, vulnerability-management requirements, cloud governance references, regulatory expectations, and client-approved asset-management rules. These are common examples and do not restrict service scope.

What the Assessment Covers

• Domains, subdomains, public IP ranges, and internet-facing services.
• Cloud-hosted resources and externally reachable systems, where discoverable and in scope.
• Exposed management interfaces, remote access portals, and outdated services.
• Certificate, DNS, email security, and web exposure observations.
• Abandoned, duplicate, test, or unknown systems.
• High-risk exposures that may require vulnerability assessment or penetration testing.

How Cryptika Delivers the Work

• Confirm approved domains, brands, IP ranges, cloud scopes, and excluded areas.
• Perform passive and authorized external discovery using agreed methods.
• Identify visible assets, services, certificates, DNS records, and exposure patterns.
• Flag unmanaged, unknown, risky, or business-critical exposures.
• Prioritize findings based on exposure, exploitability indicators, brand impact, and business context.
• Recommend remediation, ownership assignment, and ongoing monitoring improvements.

Expected Deliverables

• External attack surface assessment report.
• Inventory of identified external assets.
• Risk-rated exposure findings.
• Unknown or unmanaged asset observations.
• Recommended remediation and ownership actions.
• Escalation list for items requiring penetration testing, vulnerability validation, or urgent closure.
