When conducting corporate investigations, we implement and manage strict physical and logical security controls to ensure that all sensitive information remains completely secure. While our lawyers and corporate private investigators can work within our clients’ systems and parameters as and when necessary, we can also supply the technological and other resources required to conduct a secure, controlled, and efficient investigation.

We Provide Effective Corporate Investigation Services with Actionable Results

In order for a corporate investigation to serve its intended purpose, it needs to produce actionable intelligence, and it cannot leave questions unanswered. With our lawyers’ and former FBI agents’ extensive experience, we are able to focus our investigative efforts on gathering information our clients can use to make informed decisions, and we are able to help our clients make informed and strategic decisions based upon the information we uncover.

In broad terms, a corporate investigation can have three primary outcomes: (i) it can affirm adequate compliance and corporate security, (ii) it can expose areas where additional compliance or security measures are necessary, or (iii) it can serve as the basis for an offensive or defensive litigation strategy. As a federal compliance and defense law firm, not only do we assist our clients with corporate investigations, but we provide representation for corporate compliance, commercial litigation, and federal law enforcement matters as well.

FAQs: What Do Company Executives and In-House Lawyers Need to Know about Hiring a Corporate Private Investigator?

Q: Do I need to engage an outside law firm to conduct a corporate investigation?


Yes, regardless of your company’s size, and regardless of the nature of the investigation it needs to conduct, it is imperative to engage an outside law firm to manage and oversee the process. Not only does conducting a corporate investigation require a particular skillset and subject-matter knowledge, but engaging an outside law firm also ensures that the investigation will be subject to the protections of the attorney-client privilege.

Q: What is the process for conducting an internal or external corporate investigation?


Whether targeting information that is available internally or externally, conducting a corporate investigation involves a series of steps that need to be taken sequentially—and that need to be tailored to the specific circumstances involved. The major steps in a corporate investigation include: (i) determining the scope of the investigation, (ii) establishing necessary security protocols and procedures, (iii) assembling the investigation team, (iv) gathering all available intelligence, (v) evaluating the intelligence gathered, (vi) assessing necessary and appropriate next steps, and (vii) executing a post-investigation corporate compliance or litigation strategy.

Q: Why is it important to choose a firm that has corporate private investigators who are former FBI agents?


Former FBI agents who have decades of experience working for the agency can offer a wealth of investigative insights that can only be gained from this type of experience. Not only can former FBI agents efficiently assess the requirements of an investigation and deploy appropriate investigative strategies, but they can also examine the issues involved in the investigation from the federal government’s perspective. For issues that have potential federal law enforcement implications, this is essential.

Q: What experience and insights can a former FBI agent bring to the table during a corporate investigation?


The FBI is the nation’s top domestic investigative agency, and it pours billions of dollars into recruiting, training, and investigations each year. As a result, senior FBI agents have a wealth of knowledge and experience that they are able to utilize in helping companies conduct targeted, strategic, and effective internal and external investigations.

Q: When is it time to consult with a law firm regarding an internal or external corporate investigation?


For corporate executives and in-house lawyers who are contemplating an internal or external investigation, it is important to engage outside counsel at the outset of the investigative process. This will ensure that the entire process is as cohesive and efficient as possible, and it will allow you to rely on the firm’s advice and insights every step of the way.
