Private Investigator in Brazil Network Investigators, Corporate and Cyber Investigations Across Brazil

01Private investigation

Private Investigators in Brazil Through Our Network

When you need a private investigator in Brazil to follow someone, find someone or check someone's background, Delator Group refers the request to a vetted private investigator within our network who works the city involved and holds any licence Brazil requires. That investigator quotes the work, contracts with you directly and is responsible for carrying it out. Delator's role is to understand your situation, pick the right person for the city and the case, and stay available to you while the work is done.

Investigators in the network are vetted before they receive a referral: Delator checks identity, licensing or registration where Brazil has it, insurance where it is available, references and the quality of past reports. Rules for private investigators differ from country to country, and in some places parts of the work are restricted or reserved for licensed professionals, so the right investigator is always someone allowed to do that specific task in Brazil.

Most requests in Brazil start in São Paulo, the largest city, or in Brasilia, the capital, but the network covers every city listed on this page and the smaller places around them.

• Surveillance and activity checks
• Infidelity and family matters
• Child custody and welfare concerns
• Locating people, witnesses and heirs
• Background checks on individuals, within local privacy law
• Witness interviews and litigation support

02Three ways we help

How Delator Group Helps in Brazil

Delator Group runs two kinds of work side by side in Brazil. Private investigation in the traditional sense goes through Delator's network. Corporate investigations, cyber investigations and penetration testing are Delator's own services, scoped and staffed by Delator consultants with U.S. military intelligence, Department of Homeland Security, law enforcement, bail enforcement and technology backgrounds.

Many matters touch both sides. A corporate fraud case in Brazil may need records analysis from Delator and surveillance from a licensed local partner; a penetration test may include background checks on staff. Delator runs the engagement and the licensed part goes to a locally licensed partner in the network, so every task is done by someone allowed to do it.

03Every city

Private Investigator Pages for Every City in Brazil

Each city in Brazil with more than 200,000 people has its own private investigator page, 159 in all, grouped below by region and ordered by size. Each page covers the city's role, distances, local working conditions and how Delator Group routes requests there.

04Largest markets

Brazil's Largest Cities for Investigations

The largest cities generate most requests in Brazil: corporate offices, courts, regulators, ports and airports cluster there, and so do the people and assets that personal cases involve. Together the 159 listed cities are home to about 98,114,319 people.

Regional capitals among the listed cities include São Paulo, Rio de Janeiro, Belo Horizonte, Salvador, Fortaleza, Manaus and others. Regional capitals matter because regional courts, land and company registries and police headquarters are usually there, which is where records work and filings happen.

05Corporate investigations

Corporate Investigations in Brazil

Companies with a subsidiary, supplier, distributor or acquisition target in Brazil often need answers they cannot get from inside the business. Delator consultants scope the matter with your legal and compliance team, then lead it: corporate registry and court record research, document and transaction review, financial analysis, open-source and media research, interviews where you authorize them and local law allows, and a written report built for the board, the auditors or the courtroom.

Where part of the work is something Brazil reserves for licensed investigators, such as surveillance or background checks on individuals, that part is completed by a locally licensed partner in Delator's network.

• Employee theft, embezzlement and expense fraud
• Procurement fraud, kickbacks and bid rigging
• Bribery and corruption allegations under laws such as the U.S. FCPA and the UK Bribery Act
• Due diligence on partners, suppliers, acquisitions and joint ventures
• Intellectual property theft and counterfeiting
• Insider threats and trade secret leaks
• Asset tracing and recovery
• Supply chain and sanctions exposure reviews

06Cyber and penetration testing

Cyber Investigations and Penetration Testing in Brazil

Delator's technology consultants investigate business email compromise, ransomware and extortion, account takeovers, data leaks, insider data theft and AI-assisted fraud affecting operations in Brazil, and trace cryptocurrency where it is part of a fraud.

Delator also performs cyber and physical penetration testing in Brazil: network, cloud and application tests, social engineering, and entry tests at offices, headquarters, industrial sites and data centers. Every test runs under a written authorization signed by the owner of the systems or premises. If the scope includes background checks on employees, Delator leverages a locally licensed partner in its network to complete that work and does not do it itself.

• Breach and incident investigations
• Digital forensics on company devices and accounts
• Network, cloud and application penetration tests
• Office, industrial and data center entry tests
• Social engineering and red team exercises
• Security risk assessments and incident response planning

07Cross-border

Cases That Cross Brazil's Borders

Brazil borders Suriname, Peru, Bolivia, Uruguay, Guyana, Paraguay, Venezuela, Colombia and Argentina, and many matters cross those lines: assets moved abroad, a spouse or child taken across a border, a supplier with a parent company next door. The nearest large cities in other countries are Ciudad del Este, Paraguay (about 8 km from the nearest Brazil city on this site); Posadas, Argentina (about 244 km from the nearest Brazil city on this site); San Lorenzo, Paraguay (about 294 km from the nearest Brazil city on this site).

One Delator case lead coordinates every country involved, with network investigators and licensed partners in each, consistent evidence handling and a single report.

08Practical details

Working With an Investigator in Brazil

Common working languages in Brazil include Portuguese, Spanish and English. Delator arranges translation of interviews, records and reports when they are not in English, and builds that into the scope.

Brazil spans 3 time zones (UTC-3, UTC-4, UTC-5), so Delator schedules updates for each city involved as well as for you.

Fees for network investigators are quoted by the investigator in local terms and often in Real, while Delator's own corporate, cyber and penetration testing work is quoted in writing by Delator before anything starts.

Before the first call it helps to gather the details below. The more an investigator in Brazil knows at the start, the fewer hours are spent confirming basics.

• The city or cities involved, and any addresses
• Full names, including spellings in local script where you have them
• Recent photographs and descriptions
• Vehicles, workplaces and routines you know about
• Dates and places of the events that matter
• Court, police or case reference numbers
• Names of lawyers already involved, in any country
• What decision the findings need to support
