DUE DILIGENCE · BOCA RATON, FL
Background Checks and Documented Due Diligence
A background check answers one question: is this person or company who they say they are?
Enetsec runs documented background checks on people and companies using lawful public records and licensed data sources. Every finding is tied to the source it came from, so the file can be reviewed later. The Boca Raton lab has analysed more than 6,000 cases since 1999, including corporate counterparty diligence.
The value is not in the search. Anyone can run a name through a database. The value is in the documentation, because a finding you cannot trace back to a source is not usable in a decision anyone will later have to defend.
Every item in our reports carries its origin: which record, which registry, which date. If someone challenges the conclusion later, the file shows where it came from.
How we work, and what we will not do
We work from lawful sources only. Public records, corporate registries, court filings, property and lien records, licensed commercial databases, sanctions and watch lists, and publicly available online information.
THE BOUNDARY
We do not access private accounts, private devices or private communications without lawful authority. We do not pretext, and we do not obtain records we are not entitled to obtain. That boundary is not a marketing position. Wanderson Castilho testifies as an expert witness, and an examiner who cuts corners on sourcing is an examiner whose entire body of work becomes attackable.
If a question can only be answered by unlawful access, the honest answer is that we cannot answer it, and we will tell you that on the first call.
For companies and counsel
Corporate due diligence usually starts because something in a deal does not sit right.
We map corporate structure and ownership across entities, including where control sits behind holding companies, nominee officers or layered registrations in more than one jurisdiction. We check registration status, officers and directors, registered agents, filing history and dissolution records. We review litigation and judgment history, liens, and regulatory or sanctions exposure.
We also check whether the operating business matches the paperwork. A company with a registered address that is a mailbox, a website registered three weeks ago, and no filing history is telling you something before anyone reads a single court record.
THE SIGNAL THAT MATTERS
In our experience, the strongest signal in counterparty diligence is not a single bad record. It is the same three names surfacing across four entities that are supposed to be unrelated.
For individuals
Most people who call us privately are checking someone they met online.
Before you send money, travel to meet someone, or bring a person into your home or your family, it is reasonable to confirm that they exist as described. We verify identity against public records, check whether photographs have been used elsewhere under different names, look at how long the online presence has existed and whether it matches the biography, and review public court and property records.
This is the same work a company does before signing a contract. There is nothing embarrassing about doing it for your own life, and we have run these checks since 1999 for people who felt awkward asking.
BEFORE THE MONEY LEAVES
The result is a plain report, and often it is reassuring. When it is not, you find out before the money leaves.

Frequently Asked Questions
NO. 1 Do you handle business and corporate investigations?
Yes. Corporate work includes counterparty and vendor diligence, ownership and control mapping across linked entities, pre-acquisition checks, litigation and lien history, and verification that an operating business matches its filings. We also examine internal matters such as data taken by a departing employee or invoice fraud. Reports are written so a board, a lender or opposing counsel can follow how each conclusion was reached and from which source.
NO. 2 Do you work with legal teams and organizational leadership?
Yes, routinely. We work under attorney direction on diligence supporting litigation, transactions and internal investigations, and we brief executives and boards directly when the matter is theirs. Where counsel is engaged, we take instruction from counsel and structure the report accordingly. Wanderson Castilho served on the electronic law commission of the São Paulo bar association, and works comfortably with legal teams on both scope and documentation standards.
NO. 3 Are your digital forensic experts certified and court qualified?
Yes. Wanderson Castilho holds Cellebrite and AccessData certifications and the Certified Computer Examiner (CCE) credential, holds a BSc in Physics from the Federal University of Paraná, and is a member of the Association of Certified Fraud Examiners (Source: SEAK Expert Witness Directory, 2026). He has 21 years in practice. Certification alone does not make an examiner credible, so we also document method and sourcing on every report to make the work reproducible.
NO. 4 Has your firm been doing this since 1999?
Yes. Enetsec was founded in 1999 in Curitiba, Brazil by Wanderson Castilho, and US operations were established in 2019 with the office in Boca Raton, Florida. Across that period the practice has analysed more than 6,000 cases. That length of record matters in diligence work, because recognising a shell structure or a fabricated identity is largely a function of how many of them you have already seen.
NO. 5 How do you work with attorneys and law firms?
We take instruction directly from counsel and scope the work to the legal question, not to a generic checklist. Deliverables are built for filing: sourced findings, documented method, and a report a court can follow. We can provide declarations and affidavits, and Castilho is available for deposition and testimony. Where our findings weaken your position, we say so early and privately, because a surprise on the stand is worse than a difficult conversation.
NO. 6 Have your experts actually testified in state and federal courts?
Wanderson Castilho works as a testifying expert witness and has given 40 depositions in the past four years (Source: SEAK Expert Witness Directory, 2026). He is listed in the SEAK expert witness directory, which is one of the directories attorneys use to retain experts. We do not claim outcomes in any matter, because the outcome belongs to the court. What we can tell you is that the work has been examined under cross-examination repeatedly.
