Unveiling the Overlooked Bottleneck in Zero Trust: Secure Data Movement
In the realm of cybersecurity, a prevalent assumption is that once systems are interconnected, data transfer issues are resolved. This belief is not only flawed but also a significant impediment to the advancement of Zero Trust initiatives.
Recent findings from the Cyber360: Defending the Digital Battlespace report, which surveyed 500 security leaders across government, defense, and critical services in the U.S. and UK, reveal that 84% of government IT security leaders acknowledge that sharing sensitive data across networks amplifies cyber risks. Alarmingly, over half (53%) still depend on manual processes to transfer this data between systems, even as artificial intelligence accelerates operations on both sides.
This highlights a critical gap in Zero Trust frameworks: the movement of data itself.
Escalating Threats Outpacing Defensive Measures
The Cyber360 report documented an average of 137 attempted or successful cyberattacks per week against national security organizations in 2025, up from 127 the previous year. U.S. agencies experienced a 25% surge in weekly attack rates. Similarly, Verizon’s 2025 Data Breach Investigations Report noted that third-party involvement in breaches doubled year over year, accounting for 30% of all incidents. IBM’s 2025 Cost of a Data Breach Report estimated the average cost of a breach spanning multiple environments at $5.05 million, approximately $1 million more than breaches confined to on-premises incidents.
These statistics underscore that the interfaces between IT and operational technology (OT), between tenants, and between partner and internal environments are prime targets for cyber adversaries.
Connectivity vs. Secure Data Movement
When data traverses boundaries—be it between an OT network and the enterprise Security Operations Center (SOC), between a partner tenant and your cloud, or between classified and unclassified domains—it transitions from a routing issue to a trust issue. Data must be validated, filtered, and governed by policy before downstream systems can act upon it. This is where contemporary architectures encounter bottlenecks.
The Cyber360 data highlights specific areas of concern:
– 78% of respondents identified outdated infrastructure as a primary cyber vulnerability, citing analog systems and manual processes as weak points.
– 49% cited ensuring data integrity and preventing tampering during transit as their most significant challenge when transferring information across classified or coalition networks.
– 45% pointed to managing identity and authentication across multiple domains as their primary access challenge.
The persistence of manual processes, identity management issues across domains, and concerns about data integrity during transit collectively define an attack surface that adversaries have been exploiting for years.
Enterprise data reflects a similar narrative. Dragos’ 2025 OT Cybersecurity Report found that 75% of OT attacks now originate as IT breaches, with approximately 70% of OT systems expected to connect to IT networks within the next year. The traditional IT/OT air gap has effectively disappeared. Incidents involving managed file transfer systems further illustrate this point. The Cl0p group’s exploitation of MOVEit compromised over 2,700 organizations and exposed the personal data of roughly 93 million individuals. Similar tactics were employed against GoAnywhere and Cleo. Each of these incidents fundamentally targeted the channels that facilitate data movement between trust boundaries.
Debunking the Speed-vs-Security Dilemma
A common misconception is that organizations must choose between rapid data movement and secure data movement. In practice, many teams prioritize security, accepting delays as a trade-off. This approach may suffice when decision cycles are measured in minutes but becomes untenable when decisions are required in seconds or milliseconds.
With AI accelerating operations on both sides, detection and response pipelines are moving toward autonomous action, not waiting for gateways to complete file inspections. When 53% of national security organizations still rely on manual data transfers, the gap between AI-speed demand and analog-speed supply becomes a critical vulnerability. An AI model—whether used for fraud detection, threat triage, or targeting analysis—is only as effective as the data it processes. If data cannot move freely or cannot be trusted upon arrival, the model operates on outdated or incomplete information. The bottleneck lies not in the intelligence layer but in the underlying data movement infrastructure.
The Role of Cross-Domain Technologies
Cross-domain technologies play a pivotal role in addressing these challenges, not merely as compliance checkboxes but as essential components of a robust security architecture. When implemented correctly, they eliminate the need to choose between speed and security. They enforce trust at the boundary, enabling systems to function as a cohesive whole rather than as isolated entities connected by point-to-point integrations vulnerable to large-scale attacks.
The Cyber360 research advocates for a layered model that combines Zero Trust, Data-Centric Security, and Cross-Domain Solutions. No single framework can bridge the gap alone. Zero Trust governs who and what can access data. Data-centric security focuses on protecting the data itself, regardless of its location. Cross-domain solutions manage the movement of data between environments. Together, these frameworks facilitate secure data sharing at near-real-time speeds across classified, coalition, and operational boundaries.
This principle extends beyond defense sectors to enterprise programs where SOC data crosses OT, IT, and cloud boundaries; critical infrastructure where operational data must reach decision-makers without compromising integrity; and multi-party investigations where partner data must flow bidirectionally under strict policies.
Conclusion
The assumption that data becomes trustworthy the moment it crosses a boundary is a misconception that attackers are currently exploiting. The boundary itself is an attack surface, and data movement is where policies often fail. With over half of national security organizations still relying on manual processes for sensitive data transfers, the gap between mission speed and control speed is not just a bottleneck—it is a significant vulnerability.
