Kestralis Group conducts workplace investigations through a licensed private detective agency. Every investigation is designed from the outset with the assumption that it may need to withstand scrutiny — from HR, from Legal, or from a courtroom. We also conduct pre-hire, pre-transaction, and ongoing due diligence for organizations that need to know more than a background check tells them.
— The difference
Most internal HR investigations are conducted by people trained to manage people, not to conduct investigations. We are trained investigators, licensed to do the work, operating with methodologies that hold up when someone's attorney reviews the file.

— Overview
There are two categories of workplace investigation failure. The first is reaching the wrong conclusion — missing evidence, failing to interview the right people, or misinterpreting what the evidence means. The second is reaching the right conclusion in a way that cannot be defended — an investigation that was poorly documented, methodologically unsound, or conducted by someone without the standing to conduct it. Both failures carry serious organizational and legal risk.
Kestralis Group investigates through a licensed private detective agency, which means our investigators have the legal standing to conduct background research, surveillance, and records review that would be procedurally problematic for an unlicensed internal team. Every investigation is structured from the intake call with legal defensibility in mind — interview methodology, evidence documentation, chain of custody, and report format are all designed for the possibility that the file will be reviewed by opposing counsel.
Our due diligence capability extends beyond workplace investigations. For organizations considering a significant hire, a business partnership, or a transaction involving individuals whose background matters, we conduct structured due diligence that goes well beyond a consumer background check — public records research, source-based inquiries, OSINT analysis, and corporate record review. We tell clients what they actually need to know, not just what is easy to find.
Licensure & practice standards. Investigative services are conducted through Asymmetric Applications Group, Inc. — a Wisconsin-licensed Private Detective Agency (License No. 17196-62) under common ownership with Kestralis Group. Cross-jurisdictional engagements are conducted in compliance with the licensure requirements of each work-state — directly where AAG holds licensure, and through licensed correspondent relationships in jurisdictions requiring in-state PI licensing.
— How we work
Four phases · scoped individually to the client
We structure the engagement with privilege protection, conflict of interest, and evidentiary considerations in mind from the first call. For matters with litigation potential, we are frequently engaged through outside counsel to preserve work product protections. We define scope, timeline, and deliverables in writing before the investigation begins.
Structured witness interviews using established methodology — not conversational — are the foundation of most workplace investigations. We supplement with document review, electronic records, public records, and where warranted, licensed PI capabilities including background research and surveillance. Every step is documented to support the final report.
We evaluate the gathered evidence against the relevant standard — policy violation, legal standard, or threat risk level — and document the findings with the care that reflects the likely audience. For investigations involving behavioral risk, we apply the KTI-W as a structured annex to the factual investigation.
We produce a formal investigative report and executive summary. We brief the responsible parties — typically GC, outside counsel, or HR leadership — directly, and remain available for questions as the organization decides how to act on the findings. For matters that proceed to litigation, we are available for continued engagement.

— Common questions
A licensed private detective agency has legal standing to conduct certain forms of investigation — background research, surveillance, records access — that an unlicensed internal HR team does not. More importantly, investigations conducted through a licensed agency carry professional accountability and methodological standards that protect the organization when the results are reviewed by outside counsel or used in a legal proceeding. The license is evidence of standards, not just a regulatory formality.
Depending on what has been done and how, sometimes yes. We frequently assess the current state of an investigation and determine whether and how a corrective investigation can address the gaps without further damaging the organization's position. The sooner we are engaged after a problem is identified, the more options exist.
A standard background check queries databases — criminal records, credit, employment verification. Our due diligence conducts source-based inquiries, OSINT research, corporate records review, and where appropriate, direct field investigation. We find things that don't appear in databases — civil litigation history, reputational information, undisclosed affiliations, and behavioral patterns that a database search would never surface.
If there is any likelihood that the matter will result in litigation — termination of a senior employee, a complaint involving protected class allegations, a hostile workplace matter, or any situation involving a formal legal threat — engage outside counsel first, then have them retain us. That structure preserves privilege protections that cannot be retroactively created.
Yes, where legally and factually appropriate. Surveillance is conducted in accordance with applicable state law through our licensed PI agency. We advise on the legal parameters before any surveillance is conducted and document the engagement in a manner appropriate for the intended use of the results.
