DORA Art. 30: The ICT Due Diligence Gap
Critical gap analysis between operational resilience requirements (DORA) and cloud-native email infrastructure.
/// Executive Summary
Regulation (EU) 2022/2554 (DORA), fully applicable since January 17, 2025, mandates absolute ICT risk control for financial entities. Article 30, in particular, redefines institutional liability regarding third-party providers.
Yet recent audits reveal a systemic vulnerability across most European fintechs: outbound email communications. Routed through cloud infrastructure (Microsoft 365, Google Workspace), these flows bypass granular compliance controls, making them the number one unmonitored risk vector.
This report demonstrates the obsolescence of regex-based DLP (Data Loss Prevention) mechanisms against ACPR requirements. It establishes the need to transition toward a 'Compliance-by-Design' architecture based on SMTP interception and vector semantic analysis to ensure data integrity in transit.

Legal Analysis: The Article 30 Deadlock
DORA regulation doesn't just require security; it requires proof of control.
Contrary to common belief, outsourcing email to a cloud giant (Microsoft/Google) does not transfer regulatory liability. As stated in DORA Recital 76: 'In the event of a third-party provider's failure, the financial entity retains full responsibility for compliance with its obligations under this regulation.'
Contractual agreements must guarantee accessibility, availability, integrity, and data security. However, an email accidentally sent to an external recipient through standard infrastructure violates confidentiality the moment it leaves the server. This is the failure of 'Double Blindness': the system doesn't see what it lets out.
Sanction Scale
The stakes are significant: notification failure within 24 hours constitutes a DORA Article 19 violation. Personal data breaches can result in fines up to 4% of global revenue under GDPR. Additionally, ACPR can issue a formal warning or even revoke authorization for internal control failures.
These aren't theoretical risks—they represent active regulatory enforcement that has increased dramatically since DORA's full implementation.
The Failure of Legacy DLP Systems
The financial industry still relies predominantly on static DLP (Data Loss Prevention) systems. Our technical analysis demonstrates their structural inability to stop modern data leaks.
Traditional DLPs scan for patterns (e.g., a 16-digit sequence for credit cards). The problem: if an employee sends a 'cleaned' client file (no credit card numbers) but containing strategic data or sensitive KYC information, the DLP remains silent.
A rule-based engine doesn't understand intent. It cannot distinguish between a legitimate error and a maliciously reformulated exfiltration. This is 'Contextual Blindness'—the fundamental failure of regex-based detection.
Alert Fatigue: The Hidden Cost
Our research shows 400 hours per year lost per team to DLP false positives. With 85% false positive rates and 0% semantic intent analysis, security teams become desensitized, leading to real threats being overlooked.
The cognitive load on compliance officers creates a dangerous paradox: more alerts lead to less effective monitoring.
Case Study: Fintech 'X'
Anonymized case study of a French payment scale-up (Series B funding stage).
The scenario: Friday at 5:45 PM, the Compliance Officer wants to send an export of the 'High Risk Clients' database (KYC) to their deputy. Due to Outlook autocomplete error, they select an external homonym (a journalist).
The DLP failure: The Excel file contained no credit card numbers. Microsoft 365's DLP detected nothing. The email was sent instantly. The incident was only discovered 4 days later, following a response from the recipient.
Regulatory consequences: DORA notification deadline exceeded (24h), GDPR confidentiality violation, emergency audit triggered by ACPR. Diagnosis: This isn't human error—it's an architecture error. The system authorized sending critical data to an unauthorized domain without prior semantic analysis.
The Architectural Solution: Compliance-by-Design
To comply with state-of-the-art requirements and RTS (Regulatory Technical Standards), email architecture must evolve toward an Active Interception model.
The Deep-Link (In-Line) Model requires a Secure SMTP Gateway where all outgoing emails transit through a dedicated analysis instance before reaching the public Internet. Forced encryption with TLS 1.3 guarantees channel integrity.
Semantic Intelligence means analysis must no longer search for keywords, but understand intentions. Vector detection enables the system to understand that 'Here is the client list' sent to a @gmail.com address is a critical anomaly, regardless of the attached file's content.
WORM Auditability ensures every blocking or sending decision is logged in WORM (Write Once, Read Many) format, guaranteeing evidence immutability for investigations.
Conclusion
Outbound SMTP risk is no longer a technical hypothesis—it's a legal liability. In the post-DORA era, ignorance of this channel no longer constitutes an acceptable defense.
Financial institutions must migrate from post-facto detection to sovereign ex-ante interception to protect their license.
