Frequently Asked Questions

Category & Capability Definition

What is subsidiary risk in cybersecurity, and why does it matter?

Subsidiary risk refers to the cyber risk inherited or introduced by an organization's subsidiaries, acquired companies, or business units. These entities often have diverse IT stacks, varying security maturity, and fragmented digital footprints, making it difficult for the parent company to maintain visibility and enforce consistent security standards. Managing subsidiary risk is critical because attackers often target the weakest link in a corporate structure, exploiting overlooked assets or misconfigurations in subsidiaries to gain access to the broader organization.

What is External Exposure Management, and how does it relate to subsidiary risk?

External Exposure Management (EEM) is a cybersecurity discipline focused on discovering, validating, and remediating exploitable exposures across an organization's entire external attack surface—including subsidiaries, digital supply chain partners, and unknown assets. For subsidiary risk, EEM ensures that exposures in any business unit or acquired entity are identified and addressed, preventing attackers from exploiting gaps created by organizational complexity or rapid business changes.

How does External Attack Surface Management (EASM) differ from traditional vulnerability management?

External Attack Surface Management (EASM) focuses on discovering and validating exposures from the attacker's perspective, starting from the internet and mapping assets that may not be in internal inventories. Traditional vulnerability management typically scans known assets within the perimeter. EASM is essential for identifying risks in subsidiaries, shadow IT, and digital supply chains that internal tools may miss.

What is digital supply chain risk, and how does it impact subsidiaries?

Digital supply chain risk refers to the vulnerabilities and exposures introduced by third-party vendors, partners, and inherited IT assets that connect to or support a subsidiary's operations. These dependencies can extend the attack surface and create exposure by association, where a compromise in one entity can impact the entire organization. Ionix maps these relationships to help organizations manage and mitigate digital supply chain risk across all subsidiaries.

What is exposure validation, and why is it important for subsidiary risk management?

Exposure validation is the process of actively testing whether a discovered exposure is exploitable in the real world, rather than passively flagging potential vulnerabilities. For subsidiary risk management, validation ensures that security teams focus on exposures that matter, reducing noise and enabling faster, more effective remediation across diverse business units.

How does Ionix support CTEM (Continuous Threat Exposure Management) for subsidiaries?

Ionix operationalizes the discovery and validation stages of CTEM by continuously mapping the external attack surface of each subsidiary, validating exposures for real-world exploitability, and prioritizing remediation. This enables organizations to maintain continuous oversight and rapid response across all business units, aligning with Gartner's CTEM framework.

What is organizational entity mapping, and how does Ionix use it for subsidiaries?

Organizational entity mapping is the process of attributing discovered assets and exposures to the correct subsidiary, business unit, or owner. Ionix automates this process, ensuring that each exposure is assigned to the right team for remediation, even in complex environments with multiple subsidiaries and third-party dependencies.

Features & Capabilities

How does Ionix discover the real attack surface of subsidiaries?

Ionix uses its Connective Intelligence engine to recursively map all internet-facing assets, including shadow IT, unauthorized projects, and third-party dependencies.

These integrations embed exposure management into existing workflows and automate assignment of findings to the right teams.

Does Ionix require agents or sensors to discover subsidiary exposures?

No, Ionix is agentless. It discovers assets and exposures from the internet, requiring no deployment of agents or sensors in subsidiary environments. This enables rapid onboarding and comprehensive coverage, even for subsidiaries with limited technical resources.

How does Ionix handle digital supply chain risk for subsidiaries?

Ionix automatically maps digital supply chain dependencies for each subsidiary, identifying exposures inherited through third-party vendors, partners, and service providers. The platform provides visibility into nth-party risk, ensuring that exposures by association are discovered and remediated before they can be exploited.
