The U.S. federal government requires all agencies to adopt “Zero Trust” architecture. Naturally, some of our federal government readers may wonder: How does TDXchange, bTrade’s enterprise managed file transfer solution, fit into this environment? This blog will answer that question and demonstrate how TDXchange not only aligns with the Zero Trust mandate, but enhances it. Before diving into that, we’ll start with a quick overview of what Zero Trust means.
What is Zero Trust?
Zero Trust is a cybersecurity framework based on the principle of “never trust, always verify.” Unlike traditional security models that assume everything inside an organization’s network is trustworthy ("trust, but verify”), Zero Trust treats every user, device, and application as a potential threat. No access is granted without strict identity verification and continuous authentication, whether the entity is inside or outside the network perimeter. We’d like to walk through a hypothetical scenario to show how TDXchange aligns with these Zero Trust principles.
How TDXchange Enhances Zero Trust in Managed File Transfers
Use Case: Secure Exchange of Confidential Tax Records
This is the hypothetical scenario: A federal government agency analyst needs to securely exchange confidential tax records with outside counsel.
1. Granular Access Control
In a Zero Trust framework, access must be tightly controlled to ensure that users and systems can access only the data they need. TDXchange employs the following layered approach to access control:
IP Filtering
TDXchange lets administrators set up IP filtering for each user so that only authorized users from specific IP addresses can access each account.
Key or Certificate Validation
TDXchange uses key or certificate validation to authenticate users and systems to ensure that only trusted entities can initiate or complete file transfers.
User Relationships
TDXchange requires an explicit relationship between users for any file exchange, thereby ensuring that users exchange files only with pre-approved partners.
Multi-Factor Authentication
TDXchange adds an additional layer of access control by requiring users to verify their identity through multiple authentication factors before gaining access.
This layered approach supports Zero Trust principles of access control by ensuring that only a trusted entity, the agency analyst can initiate or complete the file transfers.
2. Secure File Transfers to Authorized Recipients
TDXchange ensures that file transfers are only made to pre-configured, authorized recipients through several mechanisms:
Organizational Hierarchy Enforcement
TDXchange ensures that users from one business unit (e.g., taxation) have no access or visibility to the configurations or transfers of users from other departments (e.g., legal). This separation maintains confidentiality and reduces the risk of cross-departmental data exposure.
Established Relationships
TDXchange ensures that file transfers can only occur between users with an explicitly established relationship. This means the analyst can only send files to authorized parties that have been pre-approved within the system, limiting exposure to unauthorized recipients.
Optional File Name-Based Delivery
TDXchange offers the option to route files based on specific file names, allowing files to be delivered only to intended recipients based on naming conventions, further securing the transfer process.
PGP or Post-Quantum Encryption with Digital Signatures
To protect transferred data, TDXchange encrypts files using either PGP encryption or NIST-approved post-quantum cryptographic (PQC) encryption algorithms, based on policy and deployment requirements. Files are encrypted both while in transit and while stored in the TDXchange datastore, ensuring confidentiality throughout their lifecycle.
PGP encryption with digital signatures provides secure, recipient-only decryption and verifies file authenticity and integrity. When PQC encryption is used, TDXchange protects sensitive data against future quantum-based attacks, supporting long-term cryptographic resilience for regulated and high-retention environments. In both cases, digital signatures ensure that files have not been altered and originate from a trusted source.
Encryption of Data at Rest
TDXchange protects data at rest using strong encryption, including NIST-approved post-quantum cryptographic (PQC) encryption where required. This ensures that stored files remain secure and unreadable even if unauthorized access to the underlying storage or datastore occurs, providing long-term protection against both current and future cryptographic threats.
By leveraging these features, TDXchange supports Zero Trust principles by guaranteeing secure, encrypted file transfers to authorized recipients only.
3. Continuous Monitoring, Alerting, and Analytics
Zero Trust requires constant vigilance. TDXchange gives you the means to achieve constant vigilance with the following features:
Real-time Tracking
TDXchange offers real-time visibility into file transfers so your IT team can see who is accessing and sharing sensitive data. This allows them to detect and address any unauthorized transfers before they become a serious threat.
Configurable Alerting
TDXchange offers highly customizable alerting capabilities. For example, if a user connection fails or an individual attempts to send files outside of an established relationship, TDXchange can immediately alert administrators of such activity. This allows for quick corrective actions, helping prevent potential security breaches or misconfigurations that could jeopardize sensitive data.
Audit Logs and Analytics
Detailed audit logs provide a comprehensive record of every action within the system, from access requests to file transfers. These logs are crucial for forensic analysis in case of a breach or policy violation. Additionally, activity reports offer insights into trends and patterns over time so IT teams can detect anomalies, optimize workflows, and improve security protocols.
Together, these features empower agencies to maintain full situational awareness, respond to threats promptly, and ensure compliance with security policies. In a Zero Trust environment, these capabilities play a crucial role in maintaining continuous oversight and accountability.
4. Adaptive Security Measures
As threats evolve, so must your security. TDXchange’s customizable security settings allow you to adapt your defenses based on emerging risks and compliance requirements. Whether it’s tightening access controls, updating encryption protocols, or refining monitoring rules, TDXchange provides the flexibility needed to stay ahead of new challenges in the Zero Trust model.
5. Integration with Zero Trust Principles
TDXchange seamlessly integrates with your Zero Trust strategy by enforcing policies that align with the model’s principles. From verifying user identities to controlling access to specific data, our solution ensures that every file transfer is subject to rigorous security checks. This integration helps reinforce your overall security posture and ensures that every aspect of your file transfer operation supports the Zero Trust philosophy.
6. Zero Trust Architecture at the Core
TDXchange is not just aligned with Zero Trust principles, it’s actually built around them. Each part of the application is designed to interact only with the entities or systems it absolutely needs to, and this access is tightly controlled, validated, and secured. By limiting access between internal components, TDXchange significantly reduces risk of unauthorized access within the system. Even if one part of the application is compromised, it can’t be used to gain entry into other areas. In short, TDXchange embodies the core principles of Zero Trust.
