Introduction
Large corporate groups face a persistent challenge in cybersecurity: maintaining complete visibility over digital assets distributed across multiple legal entities, geographic locations and operational divisions. The webinar “Управление внешним периметром холдинга: активы, риски, ответственность” (Managing the External Perimeter of a Holding: Assets, Risks, Responsibility) examines how holding companies can establish centralised oversight of their external attack surface while navigating the complexities of distributed organisational responsibility.
This virtual session targets cybersecurity leaders and IT executives responsible for protecting multi-entity organisations, addressing the operational and strategic difficulties that arise when digital perimeter management is fragmented across subsidiaries. The timing reflects growing industry recognition that traditional approaches to asset inventory and vulnerability management often fail to account for the structural realities of modern corporate groups.
About This Event
Organised by BI.ZONE, this webinar combines educational content with a practical demonstration of the company’s External Attack Surface Management platform. The session format includes structured presentations on perimeter management methodology followed by an interactive question-and-answer segment, allowing participants to explore specific implementation challenges relevant to their organisations.
The programme centres on establishing unified processes for asset discovery, risk assessment and reporting across corporate group structures. Rather than treating external attack surface management as a purely technical exercise, the session frames it within the broader context of organisational governance and operational efficiency.
The Challenge of Distributed Digital Perimeters
Holding companies and corporate groups typically operate with decentralised IT functions, where individual subsidiaries maintain varying degrees of autonomy over their digital infrastructure. This structural reality creates significant blind spots for group-level security teams attempting to understand the organisation’s complete external exposure. Assets may be provisioned, modified or decommissioned at the subsidiary level without consistent reporting to central security functions.
The webinar addresses how this fragmentation manifests in practice: incomplete asset inventories, inconsistent vulnerability data, and difficulty establishing which exposures represent genuine business risk versus theoretical concerns. When responsibility for digital assets is distributed across multiple entities without unified oversight mechanisms, the resulting gaps can persist undetected until they become security incidents.
Compounding these visibility challenges is the reporting burden placed on security teams. Consolidating perimeter data from multiple subsidiaries into coherent group-level reporting typically requires substantial manual effort, particularly when different entities use varying tools, taxonomies and assessment methodologies. The session explores approaches to reducing this operational overhead while improving data quality and consistency.
From Vulnerability Data to Risk Management
A central theme of the webinar is the distinction between identifying vulnerabilities and understanding actual risk levels. External attack surface management tools can generate substantial volumes of data about potential exposures, but translating this information into prioritised remediation decisions requires additional context about asset criticality, threat relevance and business impact.
The session examines how cyber intelligence data can inform this translation process, helping security teams distinguish between vulnerabilities that represent immediate concerns and those that pose lower practical risk given the organisation’s specific threat landscape. This intelligence-driven approach aims to focus remediation resources where they will have the greatest impact on reducing actual exposure.
For holding companies, this prioritisation challenge is amplified by the need to make consistent risk assessments across subsidiaries with different operational profiles, regulatory environments and threat exposures. Establishing common frameworks for risk evaluation enables more meaningful comparison and resource allocation across the corporate group.
External Attack Surface Management in Enterprise Contexts
External Attack Surface Management has emerged as a distinct discipline within enterprise cybersecurity, focusing specifically on assets and exposures visible from outside the organisation’s network perimeter. This includes internet-facing infrastructure, cloud resources, web applications and any other digital assets that could be discovered and potentially exploited by external threat actors.
The webinar’s practical demonstration of BI.ZONE EASM illustrates how dedicated platforms approach the challenges of continuous asset discovery, exposure monitoring and risk assessment at enterprise scale. For organisations with complex corporate structures, such tools must accommodate the reality that the external perimeter is not a single boundary but rather a collection of interconnected surfaces spanning multiple legal entities and operational domains.
Effective EASM implementation in holding company environments requires balancing centralised visibility with appropriate delegation of operational responsibility. Group security functions need comprehensive awareness of the overall attack surface, while subsidiary teams require actionable information relevant to assets under their direct control.
Building Unified Perimeter Management Processes
Beyond technology platforms, the webinar addresses the process and governance dimensions of centralised perimeter management. Achieving consistent visibility across a corporate group requires establishing common standards for asset classification, risk assessment and reporting that can be applied uniformly regardless of which subsidiary owns a particular resource.
This standardisation effort involves defining clear responsibilities between group-level security functions and subsidiary teams, establishing escalation pathways for significant exposures, and creating reporting mechanisms that provide appropriate detail for different stakeholder audiences. The goal is a management framework that scales with organisational complexity while maintaining operational efficiency.
Consolidated reporting capabilities feature prominently in the session’s discussion, reflecting the practical reality that security leaders in holding companies must communicate risk posture to executive leadership and boards in terms that aggregate subsidiary-level detail into meaningful group-wide assessments.
Who Should Attend
The webinar is designed for security and technology leaders responsible for protecting organisations with complex corporate structures. This includes Chief Information Security Officers and cybersecurity department heads at holding companies, corporate groups and organisations with extensive branch networks. Chief Information Officers with security oversight responsibilities and specialists focused on vulnerability management or external perimeter control will also find the content relevant.
The session assumes familiarity with enterprise security concepts and is oriented toward practitioners dealing with the specific challenges of multi-entity environments rather than those seeking introductory material on attack surface management principles.
Conclusion
As corporate structures grow more complex and digital footprints expand across cloud services, acquired entities and distributed operations, the challenge of maintaining unified visibility over external exposures becomes increasingly critical. This webinar offers holding company security leaders an opportunity to examine both the strategic frameworks and practical tools available for addressing these challenges, with particular attention to the organisational dynamics that distinguish multi-entity environments from simpler corporate structures.
