Are your OSINT & SOCMINT skills good enough for a due diligence investigation?

February 10, 20203 min read

Due diligence investigations examine the backgrounds of corporate entities and the principals who manage them. They are applicable to all professionals involved in investigations, insurance and risk managers, attorneys, investigative reporters, security practitioners, and every-day consumers. Business intelligence, open source research (OSINT), and social media research (SOCMINT) are key tools that assist in researching and conducting due diligence.

Hg conducts online backgrounds on businesses, persons, and entities—foreign and domestic. In employing OSINT and SOCMINT skills, we are able to expose fraudulent business enterprises, locate assets, and gather undercover intelligence. In this 4-part series, we discuss how to use public record resources, social media resources and open source monitoring, the difference between fee and free resources, and offer two case studies. This week we tackle critical definitions and share a useful list of documents to consider obtaining for your investigation.


Knowing the difference between public records and public information will help you understand some of the differences between online sites and how they gather their data.

Public Records

Public records are records of incidents or actions filed or recorded with a government agency for the purpose of notifying others—the public—about the matter. Deeds are recorded in order to keep track of property owners. Mortgages are recorded to indicate liens on the property. Prospective buyers and lenders search these records to verify ownership and determine if the property is subject to liens or easements. These records are public; anyone requiring details about your property may review or copy these documents.

Public Information

Public information is data that you freely provide to facilitate the flow of commercial and private communications. In today’s tech era, a person’s information becomes public more often than one is even aware. It’s not just your landline number in a phonebook anymore. Information placed on social network sites such as Facebook or LinkedIn becomes public. And when you sign up for a discount card at the local grocery store, you have made information about yourself publicly available to entities purchasing marketing lists.

Investigator’s Approach

Resources gathered during the investigative process are a combination of public records and public information. Combined, they can be social media accounts, statements, recordings, documents, witness interviews, news and media articles, and other published materials.

Documents can also include:

Once you identify the documents you need to begin to fill out your analysis, you need to determine where you will access this information. Next week, we launch into public record resources.
