Evaluating the strength of a bank is not just about comparing fees or the quality of a mobile app. The real issue in 2025 revolves around deposit protection, the legal status of the institution, and its ability to withstand technical incidents. Several criteria allow for sorting offers on this basis, provided you know where to look.
Deposit Guarantee and Legal Status: The First Filter for Banking Security
Not all brands offering an account protect funds in the same way. A deposit bank approved by the ACPR is part of the Deposit Guarantee and Resolution Fund (FGDR), which covers assets up to the regulatory limit per depositor and per institution.

Neobanks and certain payment institutions operate under a different regime. Their client funds are segregated into separate accounts, but this segregation does not equate to bank deposit guarantees. This distinction is rarely highlighted in general comparisons, which treat traditional banks, online banks, and neobanks as a homogeneous block.
To quickly identify the level of protection, simply check the register of financial agents (REGAFI) and see if the entity holds a credit institution license or just a payment institution status. This point radically changes the safety net in case of failure. A detailed analysis of these distinctions is provided by the safest bank according to Propatrimonia, which ranks institutions based on their financial strength.

IT Resilience and DORA Regulation: What 2025 Changes for Banking Security
The European DORA (Digital Operational Resilience Act), which came into effect in 2025, imposes enhanced requirements on financial players regarding incident management, resilience testing, and control of technology providers. Before DORA, a bank’s IT robustness mainly depended on its internal commitments.
This regulation requires each institution to document its IT subcontracting chains, conduct regular business continuity tests, and notify major incidents to supervisory authorities. For a customer, this means that a bank’s security is also measured by its digital resilience, not just by its equity.
Mobile access outages or prolonged unavailability of online services are concrete signals. A bank that experiences frequent interruptions without transparent communication poses a reliability issue, regardless of the strength of its balance sheet.
Operational Criteria to Check
- Frequency and duration of outages reported by users over the past twelve months, available through specialized forums and customer reviews
- Presence of systematic strong authentication (biometrics, two-factor validation) for account access and sensitive operations
- Quality of the emergency blocking service: availability of real-time card freezing from the app, without going through a call center
- Proactive communication from the institution in case of an incident (push notification, public status page)
Fraud and Strong Authentication: Assessing Daily Protection
A safe bank does not just protect deposits in case of bankruptcy. It must also prevent unauthorized access and detect fraudulent payments before they are completed. The quality of fraud detection varies significantly from one institution to another, even among licensed banks.
Some brands integrate real-time scoring algorithms that automatically block unusual transactions. Others rely on SMS validation, a channel increasingly targeted by SIM swap attacks. The robustness of strong authentication (biometrics, physical security key, push notification with contextual validation) is a reliable marker of an institution’s investment in customer security.
What Distinguishes the Best-Protected Banks
Institutions that publish their fraud rates or average reimbursement times after a disputed transaction offer a rare level of transparency. In contrast, those that make the dispute process opaque or slow reveal a bias against the customer.
The reimbursement time after reporting fraud is a concrete indicator often overlooked. A bank that reimburses within a few business days demonstrates mature risk management, while a process that stretches over several weeks indicates either a lack of resources or a restrictive policy.
Solvency Ratio and Financial Strength: Reading the Right Indicators
The CET1 (Common Equity Tier 1) ratio measures a bank’s ability to absorb losses with its highest quality equity. The higher this ratio, the more the institution has a safety cushion against an economic shock.
Large European banks publish this ratio in their quarterly financial reports. A CET1 ratio significantly above the regulatory minimum indicates a comfortable margin of maneuver. Online banks backed by a banking group generally inherit the ratio of their parent company, giving them a solidity comparable to physical networks.
- Check the latest Pillar 3 report of the institution, available on its institutional website
- Compare the displayed CET1 ratio with the minimum threshold required by the ECB for that specific institution
- Verify if the bank has recently been subject to recommendations or sanctions from the ACPR
The legal status, deposit guarantee, post-DORA IT resilience, and fraud management form a set of criteria that far exceeds the usual price comparison. Cross-referencing these four dimensions allows for identifying truly solid institutions, beyond marketing rankings.
