Most people assume that when they send an email, message, or file, it remains under their control. In practice, that depends entirely on who operates the underlying system.
Today, most business communications rely on third-party platforms—email providers, messaging apps, cloud storage and collaboration tools. These services are convenient and widely adopted, but they introduce a critical dependency that is often overlooked: control sits with the provider and their providers, not the organisation as a client of those systems.
The key issue is control, not intent
A single communication may pass through multiple systems operated by different vendors. Data may be stored, replicated, analysed and monitored across several environments. Additional services may inspect content for security, compliance, or operational purposes. In effect, modern communication exists within a complex ecosystem of third-party dependencies that is largely opaque to the end user.
Even where providers offer encryption or privacy assurances, the underlying reality remains unchanged: the organisation does not control the system.
This matters because the provider determines:
- how the platform operates
- what data is collected and retained
- how information is processed, monitored, or shared
- which third parties are involved
- how the service evolves over time
Users are operating within an environment they do not govern.
What ownership changes
Organisations that operate their own communication systems gain direct control over:
- where data is stored
- who can access it
- retention and deletion policies
- security controls and monitoring
- external dependencies and integrations
This does not eliminate risk. Poorly managed systems can still fail. However, it shifts the organisation from dependency to control.
Why this matters at board level
For organisations handling sensitive or regulated information—commercial negotiations, intellectual property, financial data and customer records—this distinction is material. Once data is placed into a third-party system, trust becomes implicit and dependent on external governance, contractual assurances and the provider’s own supply chain.
Many organisations invest heavily in securing their internal environments while simultaneously placing critical communications into externally controlled systems.
The systemic risk: dependency at scale
Recent large-scale outages across major cloud providers highlight the impact of this dependency:
- Microsoft 365 outage (July 2025): Approximately 19 hours of disruption affecting email, authentication and collaboration services globally, few businesses were able to operate, only those running non-microsoft dependant digital workplaces were unaffected.
- AWS outage (October 2025): Regional failure cascading across multiple dependent services, impacting global applications and consumer platforms; Millions of IoT devices rendered unusable (fridges, beds, blenders, heating systems, TVs, security systems, home automations).
- Google Cloud outage (June 2025): API and identity failures causing widespread service disruption across multiple industries, multiple automations in GCP/GCS & google cloud data environment dependant services rendered completely unusable.
In each case, organisations experienced loss of access to core communication and operational systems—not due to internal failure, but due to external platform dependencies.
These events illustrate a simple reality: availability and control are ultimately constrained by the systems you do not own.
The main question for leadership is straightforward:
Who controls the systems carrying your communications?
If the answer is a third-party provider, then confidentiality, availability and integrity are ultimately dependent on external decisions, infrastructure and supply chains.
Ownership does not guarantee security—but it does establish control, accountability and the ability to govern risk directly.
For organisations where communication is mission-critical, this distinction is strategic, not technical.
