Not every customer requires the same level of scrutiny. That’s the core principle behind Simplified Due Diligence (SDD)—a regulatory approach that adapts compliance to the actual risk level of a customer or transaction.
In this article, you’ll learn what SDD really means in the context of AML compliance, how it compares to CDD and EDD, and when it can be safely applied. You’ll also understand the operational and regulatory differences between customer verification levels and how Veridas supports these processes through scalable identity solutions.
What does SDD mean in compliance?
SDD stands for Simplified Due Diligence. It refers to a lighter version of the customer verification process used in low-risk situations. Regulatory frameworks such as the EU’s AMLD and guidelines from the Financial Action Task Force (FATF) allow for this adjusted approach, provided the risk of money laundering or terrorist financing is demonstrably low.
In practice, SDD allows institutions to reduce the intensity or scope of identity verification. For example, a government benefit disbursement system or a low-limit prepaid card might not require full document checks or transaction monitoring. However, institutions are still responsible for ensuring that their SDD process complies with regulatory expectations.
SDD is not the absence of due diligence—it’s a tailored version of it. The risk profile must justify the lighter checks, and there should always be mechanisms in place to escalate to standard or enhanced due diligence if needed.
What is Consumer Due Diligence (CDD)?
Consumer Due Diligence (CDD) is the default level of identity verification applied to most customers in regulated sectors. It ensures that institutions can accurately identify and assess the individuals or entities they’re doing business with. CDD is the foundation of all AML and KYC programs.
CDD requires institutions to collect key data, verify identity through reliable sources, and understand the nature and purpose of the customer relationship. It applies to banks, fintechs, insurers, payment providers, and any other entity dealing with financial transactions or customer onboarding.
This process helps detect irregularities, flag suspicious activity, and meet reporting obligations. Without it, financial institutions face legal, operational, and reputational risks.
The primary purpose of CDD
The core objective of CDD is to create a risk-based identity profile of the customer. By identifying and verifying customers reliably, institutions can establish a baseline for behavior and detect anomalies early.
It’s also about accountability. CDD supports audits, regulatory reviews, and investigations by providing documented evidence of customer checks. It ensures traceability, transparency, and trust within financial systems.
Moreover, CDD allows for risk segmentation. Institutions can assign higher scrutiny to complex cases and streamline low-risk interactions accordingly, improving both security and user experience.
The 4 pillars of CDD
While implementations vary, CDD typically includes four main components:
- Customer identification: Collecting key data such as name, date of birth, nationality, address, and unique identifiers.
- Customer verification: Validating that information through government-issued documents, digital identity systems, or third-party databases.
- Understanding the relationship: Knowing why the customer is opening the account, expected activity levels, and whether the product fits their profile.
- Ongoing monitoring: Continuously assessing transactions, behavior, and potential red flags through automated or manual reviews.
These four pillars form a loop, not a linear process. Effective CDD requires periodic reassessment and responsive risk management over the entire customer lifecycle.
Difference between CDD, EDD, and SDD
CDD, EDD, and SDD are all part of a risk-based identity verification framework. The differences lie in the depth and scope of checks applied based on the perceived customer risk.
CDD vs EDD
CDD is the default standard for identity verification. Enhanced Due Diligence (EDD), however, is required when the risk profile exceeds the norm—such as in cases involving politically exposed persons (PEPs), offshore companies, or unusually large transactions.
EDD includes additional layers: verifying source of funds, deeper document authentication, cross-border checks, and tighter transaction monitoring. While CDD focuses on confirming who the customer is, EDD focuses on why their risk is higher and how to mitigate it.
CDD vs KYC
Know Your Customer (KYC) is the overarching obligation, and CDD is one of its core components. KYC covers the full lifecycle—from onboarding to offboarding—and includes CDD, EDD, and other processes such as sanctions screening and beneficial ownership checks.
In short, CDD is how KYC gets operationalized. It’s the mechanism through which identity is validated and customer risk is categorized.
CIP vs CDD
Customer Identification Program (CIP) refers to the act of collecting and verifying basic identity information at the time of account opening. It’s usually the first step in the KYC journey.
CDD expands on CIP by including additional steps like relationship profiling and ongoing monitoring. Think of CIP as the entry point and CDD as the full gatekeeping process.
When to apply Simplified Due Diligence (SDD)
Simplified Due Diligence is only permitted when there is a legitimate, documented reason to classify a customer or transaction as low risk. Regulatory bodies require financial institutions to justify SDD through a risk-based assessment process.
Typical scenarios where SDD may be used include:
- Basic savings accounts with low transaction limits
- Government-funded benefit programs
- Services offered by regulated public authorities
- Accounts where no cash withdrawals or deposits are allowed
In each case, the institution must document why standard or enhanced due diligence is not necessary. The presence of external supervision, verified public funding, or low financial exposure are some of the common justifications.
Even under SDD, systems must include real-time risk monitoring and escalation mechanisms. If the customer’s behavior changes or new risks are identified, institutions must shift to CDD or EDD accordingly.
Key takeaways on SDD and CDD
Simplified Due Diligence and Customer Due Diligence are both part of a layered compliance strategy. Knowing when to use each depends on risk assessment, regulatory guidance, and internal policy.
Here are the essentials:
- SDD applies only in well-justified low-risk cases and allows lighter verification.
- CDD is the standard level required for most customers, combining ID verification with risk monitoring.
- EDD is mandatory for high-risk clients, requiring extra scrutiny.
- CIP is the basic first step, often integrated into CDD.
- Veridas offers a scalable platform to automate and secure due diligence across all levels using biometrics, document analysis, and behavioral intelligence.
No matter the level of diligence applied, institutions are ultimately accountable for ensuring that every onboarding process is defensible, secure, and aligned with global AML standards.
