OSINT 101
In today’s compliance landscape, Enhanced Due Diligence (EDD) is no longer reserved for edge cases — it’s a frontline defence against financial crime. For MLROs in law and accounting firms, the ability to conduct robust EDD hinges on more than just internal data and client declarations. It requires strategic use of Open Source Intelligence (OSINT).
What Is OSINT?
OSINT refers to the collection and analysis of publicly available information to support investigative decision-making. In the context of AML, it means leveraging online sources — from corporate registries and news archives to social media and sanctions databases — to build a fuller picture of a client’s risk profile.
Unlike traditional data sources, OSINT is dynamic, decentralised, and often unstructured. But when used correctly, it can reveal hidden connections, reputational red flags, and jurisdictional exposure that standard onboarding processes may miss.
How OSINT Supports EDD
EDD is triggered when a client presents elevated risk — for example, being a Politically Exposed Person (PEP), operating in a high-risk jurisdiction, or using opaque legal structures. OSINT complements formal checks by:
- Validating declarations: Cross-checking client-provided information against public records
- Identifying adverse media: Surfacing reputational risks not captured by standard screening tools
- Mapping networks: Revealing links to sanctioned entities, shell companies, or high-risk sectors
- Assessing behavioural context: Analysing transaction patterns, public statements, or litigation history
Skills Required for Effective OSINT
OSINT is not just about Googling. It requires a structured approach and specific competencies:
- Source evaluation: Distinguishing credible data from noise or misinformation
- Search logic: Using advanced operators, multilingual queries, and domain-specific platforms
- Data synthesis: Connecting disparate pieces of information into a coherent risk narrative
- Tool fluency: Navigating platforms like OpenCorporates, Sayari, World-Check, and social media aggregators
MLROs don’t need to be cyber sleuths — but they do need to know what to look for, where to look, and how to interpret what they find.
When OSINT Is Unlikely to Be Necessary
For low-risk clients — such as domestic individuals with transparent income sources and simple needs — OSINT may not be required. In these cases, simplified due diligence (SDD) is often sufficient, provided the initial risk assessment is well-documented and proportionate. The goal is to apply investigative effort where it adds value, not where it creates unnecessary friction.
Practical Example: EDD on a PEP from a High-Risk Country
Let’s say your firm is onboarding a client who is a senior official in a high-risk jurisdiction, with declared interests in a Dubai-based holding company.
Using OSINT, your EDD process might include:
- Corporate registry checks: Verifying directorships and shareholder structures via OpenCorporates or national registries
- Adverse media screening: Running multilingual searches across news archives and aggregators like Nexis or Google Advanced Search
- Sanctions and watchlists: Checking against OFAC, EU, UN, and regional lists using tools like World-Check or Sanctions Scanner
- Social media mapping: Identifying affiliations, public statements, or reputational concerns via LinkedIn, Twitter, or local platforms
- Crypto exposure: Searching blockchain analytics platforms for wallet addresses linked to the client or their entities
This layered approach helps build a defensible risk profile — one that goes beyond tick-box compliance and demonstrates proactive risk management.
Why OSINT Matters
In an era of increasing regulatory scrutiny and geopolitical complexity, OSINT is no longer optional. It’s a strategic capability that enhances your firm’s AML posture, protects reputation, and supports defensible decision-making.
Firms that invest in OSINT skills and workflows are better equipped to:
- Spot hidden risks before they become liabilities
- Justify onboarding decisions with documented intelligence
- Respond confidently to regulator queries and audits
- Embed proportionality into their AML framework
Final Thought
An effective OSINT strategy is not just about tools — it’s about mindset. It empowers MLROs to think critically, act proportionately, and document defensibly. In the context of EDD, OSINT is the difference between surface-level checks and meaningful risk insight.
For law and accounting firms navigating complex client relationships, OSINT skills offer a powerful addition to your AML toolkit.
