Financial services & banking.
Strong customer authentication, fraud signals at every step, and a compliance posture that survives a regulator's audit.
How this vertical uses CIAM
Customer identity in financial services lives at the intersection of regulation and fraud loss. Regulators care about who authenticated, how, and whether the bank can prove it months later. Fraud teams care about whether the session, device, and behavior match the customer 30 seconds after auth. CIAM has to serve both, which is a different job from the developer-friendly login flows that suffice for most consumer apps.
Two architectural patterns dominate. Tier-1 banks operate hybrid stacks: a legacy enterprise IAM (often ForgeRock, Ping, or Oracle) handles the system of record, while a modern orchestration layer (Transmit Security, Authsignal, Beyond Identity) sits in front for adaptive authentication, behavioral signals, and step-up. Challenger banks and fintechs default to a single managed CIAM (Auth0 enterprise, Stytch, Descope) plus a dedicated fraud vendor (Sift, Forter) wired in via webhook.
The regulatory bar around Strong Customer Authentication and dynamic linking under PSD2 means push-OTP-and-pray is dying. Push-with-context, transaction signing, FIDO2 / passkeys, and device-bound credentials are now the realistic baseline. Audit logs need to capture the signed authentication context, not just 'user X logged in at time T'.
Key use cases
Strong customer authentication (SCA)
Two-of-three factor authentication for payment initiation and account access, with dynamic linking between the auth event and the transaction amount and payee. CIAM vendor must support FIDO2 / passkeys, device-bound credentials, and signed authorization payloads.
Transaction signing and step-up
Risk-tiered flows where low-risk operations stay frictionless and high-risk operations (wire transfers, beneficiary adds, profile changes) require a fresh authentication bound to the specific transaction. Requires push notifications, biometric step-up, and policy-driven orchestration.
Continuous authentication and ITDR
Behavioral biometrics, device fingerprinting, and session risk scoring that runs after login. Anomaly triggers session re-auth, transaction hold, or fraud-team review. Bank tolerance for false positives is low, which favors vendors with mature risk models.
Account opening (eKYC) and identity verification
Onboarding flow with document capture, liveness, sanctions screening, and address verification. Often a third-party IDV vendor (Onfido, Persona, Jumio, Trulioo) called from the CIAM orchestrator, with the verified attributes attached to the customer profile.
Joint accounts, legal guardians, fiduciaries
Identity models that go beyond one-user-one-account: joint owners, powers of attorney, trustees, beneficiaries with limited access. Requires entitlement and delegation modeling that most consumer CIAM is too thin to express.
Regulator-grade audit and consent
Tamper-evident audit logs capturing the full authentication context (factors used, device, signals, policy version) and a consent ledger covering marketing, data-sharing, and Open Banking authorization. Both must be queryable months later under regulator request.
Regulatory floor
A practitioner read of the rules that shape vendor selection here. Not legal advice, see disclaimer.
- PSD2 / PSD3 (EU)
- Strong Customer Authentication with two of three factors plus dynamic linking for payments. PSD3 (proposed) extends to broader account-information services and tightens fraud reporting.
- FFIEC authentication guidance (US)
- Risk-based authentication for online banking. Periodic re-validation of controls, especially around high-risk transactions.
- NY DFS Part 500 / state DFS rules
- MFA on all privileged access and customer access where 'nonpublic information' is involved. Annual CISO certification.
- SOC 2 Type II + ISO 27001
- Table stakes for the CIAM vendor itself. Banks will request the report under NDA before contracting.
- DORA (EU)
- Operational resilience for ICT third parties including identity providers. Concentration risk and exit testing now a contracting concern.
- PCI DSS 4.0
- If the CIAM stack ever touches card data context (even auth around a card-on-file change), PCI scoping applies.
- GLBA + state privacy laws (US)
- Customer information safeguards plus state-level consent and data-subject rights (CCPA/CPRA, plus the wave of 2024-2026 state laws).
What tilts the decision
- Demonstrated FIDO2 / passkey orchestration including device-bound enrollment and recovery flows.
- Built-in or first-class integration for behavioral biometrics and device risk (own product or close partner).
- Audit log export to the bank's SIEM in a format that survives a regulator subpoena (immutable, timestamp-signed).
- DPA, sub-processor list, EU/US data residency options. SOC 2 Type II, ISO 27001 evidence available pre-contract.
- Concentration-risk story: clear runbook for vendor exit, data export, and continuity (DORA-driven).
- Predictable pricing at large MAU bands. Per-MAU plus per-MFA-event pricing can blow up at retail-bank scale.
Vendors that excel here
Our editorial pick of CIAM platforms that consistently fit this vertical's constraints. Vendors named here win deals or run production for the reasons listed; they are not the only viable choices. See the full vendor index for breadth.
Transmit Security
Purpose-built for financial services: orchestration, passkeys, behavioral biometrics, and account-protection in one stack. The deepest fraud-aware identity offering in the category. Trade-off is enterprise-grade pricing and complexity.
Ping Identity
Established footprint in tier-1 banks. Strong on enterprise SSO, federation, risk-based auth, and DaVinci orchestration. Pairs well with a dedicated fraud vendor.
ForgeRock
Now part of Ping (post-acquisition) but the customer-identity stack still ships independently. Strong intelligent-access scripting, deep customization for joint-account and fiduciary models.
Authsignal
Drop-in challenge orchestration that layers on top of an existing IAM. Passkeys, push-with-context, transaction signing, and risk policies without ripping out the system of record. Common pattern in fintechs and digital-only banks.
Beyond Identity
Device-bound, phishing-resistant authentication with no shared secrets. Strong fit for high-value customer accounts and internal banker access where SCA quality matters more than UX freshness.
Honorable mentions
Auth0 (Okta CIC)
Common at fintechs and challenger banks. Adaptive MFA, attack protection, enterprise SSO. Works if you pair it with a dedicated fraud vendor and accept that some bank-specific identity modeling sits in your app.
IBM Security Verify
Long-tail tier-1 bank deployments, especially where IBM is already the platform partner.
Curity
Strong OAuth / OIDC / FAPI compliance, common in European Open Banking and PSD2 deployments where a financial-grade API profile is non-negotiable.
What 2027-2030 looks like
Trends our editorial team is tracking for this vertical, with the horizon when we expect mainstream adoption. Reviewed each quarter.
FIDO2 / passkeys become the default SCA factor
2026-2027Push-OTP and SMS-OTP keep declining as regulators flag SIM-swap fraud. By 2027, expect passkey-based SCA to be the default in new product launches and a stated migration goal at major retail banks.
Behavioral biometrics moves from add-on to baseline
2026-2027CIAM and fraud are converging. Either the CIAM vendor ships behavioral biometrics natively (Transmit, Ping, Authsignal direction) or it standardizes a webhook contract with a fraud vendor (Sift, Forter, BioCatch) deep enough to drive step-up.
Verifiable credentials for KYC reuse
2027-2028eIDAS 2.0 wallets in Europe and equivalent state-level digital ID pilots in the US make verifiable credentials a realistic input to account opening. CIAM platforms will accept signed VCs as evidence and skip parts of eKYC for returning customers.
Agentic banking and signed delegation
2027-2028Customers will start authorizing AI agents to act on their accounts (bill pay, account aggregation, advisory). Banks need an identity model that issues scoped, time-boxed, revocable credentials to non-human principals, and an audit trail that distinguishes 'customer did X' from 'customer's agent did X under this scope at this confidence'.
Post-quantum migration of customer-facing crypto
2028-2030Bank security teams begin migrating TLS, signing keys, and HSM-backed customer crypto to post-quantum algorithms. CIAM vendors that ship hybrid-PQ flows early will have a moat at the regulated end of the market.
Continuous identity and risk-based session lifetime
2028-2030Static session lifetimes give way to continuous evaluation. Sessions live as long as the device, behavior, and network signals stay coherent; they die or step up the moment they don't. Becomes the operational default for high-value banking sessions.
