System exposure addresses critical risks when servers, applications, and infrastructure are exposed to the internet. This category covers directly connected internal systems, remote sites, gateway devices, cloud platforms, and vendor-managed infrastructure that may lack proper security controls or oversight, creating significant attack surface expansion.
Systems accessible from the internet that are directly connected to the internal network, often in a DMZ, such as websites, email servers, or remote access gateways.
Lateral movement risk, data breach potential, service disruption, increased attack surface, internal network compromise
Systems at remote sites, branch offices, or satellite locations that are suspected but not confirmed to be connected to the internal corporate network.
Potential lateral movement, data exposure risk, service disruption, limited oversight vulnerabilities
Internet gateway devices such as routers, firewalls, or VPN concentrators that are publicly exposed and provide critical network infrastructure services.
Network infrastructure compromise, complete network access, business continuity disruption, regulatory compliance violations
Business applications and systems hosted in cloud environments that are exposed to the internet, including SaaS platforms and cloud-hosted services.
Data exposure in cloud environments, service availability risks, compliance violations, multi-tenant security issues
Systems that appear to belong to or support the organization based on branding or naming conventions, but without clear ownership or explicit connection verification.
Brand reputation risk, unclear security responsibility, potential shadow IT exposure, compliance uncertainty
Systems managed by external contractors or vendors that support organizational operations but are not under direct internal control or oversight.
Third-party security risks, vendor compliance issues, limited security visibility, supply chain vulnerabilities
Global manufacturer discovered their internet-facing production planning system in the DMZ was compromised, allowing attackers to access internal manufacturing schedules, supplier information, and production line control systems across 12 facilities.
Regional bank found their VPN concentrator exposed with default credentials, leading to complete network access and the theft of customer account information, transaction records, and internal financial data for 200,000+ customers.
Hospital network discovered a vendor-managed patient portal exposed sensitive medical records, insurance information, and treatment data for 150,000 patients due to misconfigured cloud security settings and inadequate vendor oversight.
Don't let exposed systems become entry points for attackers. Our CTEM-EXP monitoring identifies internet-facing infrastructure vulnerabilities across your entire ecosystem before they become incidents.
