The Challenge: Timing Out with Traditional Protocols
The bank approached us in 2011 with a pressing issue: their existing eDiscovery process was inefficient, costly and prone to many failures. The nature of eDiscovery often involves the collection, processing, and distribution of large volumes of sensitive data, emails, documents, transaction records, and more. The bank needed to transfer these vast data collections to external legal firms, auditors, and various government regulators across the globe quickly, securely, and without interruption.
However, they were experiencing significant delays and even failures when sending large data sets via traditional Secure File Transfer Protocol (SFTP) or HTTPS. These protocols were timing out, leading to frustrating delays in the eDiscovery process, which not only impacted the bank's operational efficiency but also put them at risk of non-compliance with strict regulatory timelines.
Why eDiscovery File Transfers Often Fail
Many organizations assume eDiscovery challenges are primarily legal.
In reality, they are often infrastructure challenges.
Common issues include:
- Large datasets exceeding traditional transfer capabilities
- Transfer timeouts
- Network latency
- Failed deliveries
- Manual packaging and distribution
- Limited auditability
- Inconsistent chain-of-custody tracking
As data volumes continue to grow, these issues become increasingly difficult to manage using traditional transfer methods.
Why Chain of Custody Matters in eDiscovery
One of the most overlooked aspects of eDiscovery is proving the integrity of the evidence.
Organizations must demonstrate:
- Who accessed the data
- When transfers occurred
- Where data was sent
- How data was protected
- Whether files were altered
- What security controls were applied
TDXchange helps maintain defensibility through:
- Detailed audit trails
- Transfer traceability
- Authentication controls
- Role-based access management
- Encryption
- Centralized reporting
This provides organizations with evidence required during audits, litigation, and regulatory reviews.
Why Financial Institutions Need Accelerated File Transfer
Banks and financial institutions often face unique challenges:
- Regulatory deadlines
- Large investigation datasets
- Cross-border data movement
- Multiple external parties
- High sensitivity information
- Strict audit requirements
Accelerated transfer technology allows organizations to meet these requirements while reducing operational risk and improving response times.
