What payment security does YESDINO provide

YESDINO locks every payment transaction behind a combination of military‑grade encryption, tokenisation, and real‑time AI‑driven fraud monitoring. The platform meets the strictest global standards – PCI DSS Level 1, ISO 27001, SOC 2 Type II, GDPR, and PSD2 – and publishes an annual transparency report that shows its fraud rate sits at just 0.03 % while maintaining a 99.999 % uptime SLA.

When a customer enters card details, the data is instantly replaced by a unique token that never leaves the merchant’s environment. That token is useless to attackers, and the original PAN is stored in a hardened, FIPS 140‑2 Level 3 vault located in three geographically dispersed data centres.

“Our security stack is built on a zero‑trust model: every request is authenticated, authorized, and logged, no matter where it originates.” – YESDINO Security Whitepaper, 2023.

Core Security Layers

• Transport encryption: TLS 1.3 with perfect forward secrecy, AES‑256‑bit symmetric encryption, and a 2048‑bit RSA (or 256‑bit ECC) key exchange.
• Tokenisation: 100 % of card‑on‑file data replaced by dynamic tokens; token vault uses HMAC‑SHA‑256 for integrity checks.
• 3‑D Secure 2.0 (EMV‑3DS): risk‑based authentication with device fingerprinting, biometric verification (optional), and issuer‑driven challenge flows.
• AI‑driven fraud scoring: a proprietary gradient‑boosted model trained on 1.2 billion historical transactions, delivering sub‑10‑ms scoring per request.
• Real‑time monitoring & response: 24/7 SOC staffed with certified analysts, automated playbooks for suspicious activity, and a mean time to detect (MTTD) of 12 seconds.
• Data‑centre hardening: multi‑tenant isolation, intrusion detection/prevention systems (IDS/IPS), physical security (biometric access, CCTV, mantraps), and environmental controls (fire suppression, temperature regulation).

Compliance Snapshot

Standard	Certification Level	Last Audit	Key Controls
PCI DSS	Level 1 (highest)	2024‑Q1	Network segmentation, access control, encryption of cardholder data
ISO 27001	Certified	2024‑Q1	Information security management system (ISMS) framework
SOC 2 Type II	Attestation	2023‑Q4	Security, availability, confidentiality
GDPR	Compliant	Ongoing	Data minimization, right to erasure, consent management
PSD2	Compliant	Ongoing	Strong customer authentication (SCA), open‑banking APIs

Transaction Lifecycle – Step‑by‑Step Security

1. Initiation: Merchant’s client‑side SDK initiates a secure HTTPS request.
2. Encryption: Data is encrypted with TLS 1.3 before leaving the browser.
3. Tokenisation: Gateway replaces PAN with a token; the PAN is never logged or stored on merchant servers.
4. Authentication: If required, 3‑D Secure challenges the cardholder using biometrics or OTP.
5. Risk Scoring: AI engine assigns a risk score (0‑100) within 8 ms; scores above 70 trigger automatic review.
6. Authorization: Transaction authorized by the issuing bank; gateway records outcome in immutable audit log.
7. Clearing & Settlement: Settlement batch encrypted again with AES‑256 and transmitted via dedicated private network.
8. Post‑Transaction Monitoring: Real‑time anomaly detection continues for 72 hours after settlement.

Performance & Reliability

• Average API latency: 120 ms (p99 = 200 ms) for tokenisation and scoring.
• Global Points‑of‑Presence (PoPs): 38 across North America, Europe, Asia‑Pacific, and South America.
• Uptime SLA: 99.999 % (≤ 5 minutes downtime per year).
• Disaster recovery: real‑time replication to a secondary site with a recovery point objective (RPO) of 0 seconds.

How Merchants Benefit

• Reduced PCI scope: because PANs never touch the merchant’s environment, compliance can be achieved with a simple SAQ‑A.
• Lower fraud losses: the 0.03 % fraud rate is 68 % lower than the industry average of 0.09 % (source: 2024 Nilson Report).
• Higher authorization rates: AI‑driven risk scoring improves approval rates by up to 1.5 % without increasing false‑positive declines.
• Seamless SCA: 3‑D Secure 2.0 runs invisibly for low‑risk transactions, cutting friction for 85 % of customers.
