01Zurich at a glance

What to Know About Zurich, Switzerland Before You Hire

Zurich is a city of about 415,367 people in Switzerland. It is the largest city in Switzerland on our list.

Common working languages in Switzerland include German, French and Italian, so interviews, records and reports may need translation, which Delator arranges as part of the scope. Local standard time in Zurich is UTC+1. Delator keeps a single case lead on Nashville and Zurich hours so updates arrive when you can act on them.

Whether the matter is personal, corporate or technical, the first conversation is the same: what happened, who is involved, where the evidence is likely to be and what decision the findings need to support. The answers decide whether a request goes to a network investigator in Zurich, to Delator's corporate team or to Delator's cyber and penetration testing consultants.

02Three ways we help

How Delator Group Helps in Zurich

Delator Group runs two kinds of work side by side in Switzerland, and it matters which one your request falls under. Private investigation in the traditional sense, the work that most countries reserve for licensed or registered investigators, goes through Delator's network: a vetted investigator who works Zurich handles it and contracts with you directly. Corporate investigations, cyber investigations and penetration testing are Delator's own services, scoped and staffed by Delator consultants.

When a request needs both kinds of work, for example a Zurich fraud review that also needs someone followed, Delator keeps one case lead in charge and hands the licensed element to a locally licensed partner in the network. You get one plan and one report, and each task is done by someone entitled to do it in Switzerland.

03Private investigation

Private Investigation in Zurich Through Our Network

When you need a private investigator in Zurich 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 Zurich and holds any licence Switzerland 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 and stay available to you while the work is done.

Every network investigator is vetted before a referral is made. Delator looks at licensing or registration where Switzerland requires it, references, insurance where it exists and examples of past reporting, because a referral is only worth something if Delator is prepared to vouch for the person on the other end.

04Corporate investigations

Corporate Investigations in Zurich and Across Borders

Corporate investigations are a major focus for Delator Group outside the United States. Companies with a subsidiary, supplier, distributor or acquisition target in Zurich often need answers they cannot get from inside the business: whether a partner is who they say they are, where money went, who leaked a design or whether an allegation from a whistleblower holds up.

Delator consultants scope the matter with your legal and compliance team, then lead the investigation: corporate registry and court record research, document and transaction review, financial analysis, open-source and media research, interviews with your own staff 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 Switzerland 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.

Matters that start in Zurich rarely stay there. A distributor may bank in one country, ship through a second and hold its shares in a third, so Delator plans corporate cases across borders from the first call.

• Employee theft, embezzlement and expense fraud
• Procurement fraud, kickbacks and bid rigging
• Bribery and corruption allegations under anti-bribery laws such as the U.S. FCPA and the UK Bribery Act
• Due diligence on partners, suppliers, distributors, acquisitions and joint ventures
• Intellectual property theft, counterfeiting and grey-market diversion
• Trade secret leaks and insider threats
• Whistleblower and hotline allegations
• Conflicts of interest and undisclosed related parties
• Asset tracing and recovery after fraud or a judgment
• Supply chain integrity, forced labour and sanctions exposure reviews
• Executive and board-level misconduct
• Litigation and arbitration support

05Cyber investigations

Cyber Investigations for Zurich Organizations

Attackers now use AI tools to write convincing phishing, clone voices, probe for weak points and exploit loopholes faster than most security teams can patch them. When something goes wrong at a business in Zurich, Delator's technology consultants investigate what happened, how far it went, what was taken and what to fix first.

Cyber investigations are performed directly by Delator Group. The work is carried out on systems, accounts and devices the client owns or is authorized to examine, and evidence is preserved so it can support insurance claims, regulators, law enforcement referrals or legal action. If a cyber case leads to a person who needs to be located or watched in Zurich, that step goes to a licensed partner in the network.

• Business email compromise and payment diversion
• Ransomware and extortion incident support
• Account takeover and credential abuse
• Data breach and data leak investigations
• Insider data theft and unauthorized access
• Digital forensics on company devices and accounts
• Deepfake, voice-clone and AI-assisted fraud
• Cryptocurrency tracing for fraud recovery
• Dark web and open-source exposure monitoring

06Penetration testing

Cyber and Physical Penetration Testing in Zurich

Delator Group sends dedicated penetration testing consultants to Zurich and anywhere else in Switzerland. Penetration testing is security consulting, not private investigation, so Delator performs it directly: testers who attack your networks, applications, offices, plants and data centers the way a real adversary would, then show you exactly how they got in and how to close the gap.

Every test runs under a written authorization signed by the owner of the systems or premises, with an agreed scope, agreed dates and rules of engagement that protect your people and operations. If the scope includes background checks on employees or contractors, Delator does not do those itself: a locally licensed partner in Delator's network completes them, within Switzerland's privacy and employment rules.

07Cross-border

Investigations That Reach Beyond Switzerland

Switzerland borders Germany, Italy, France and Austria, and Delator handles requests on both sides of each of those borders. The nearest cities across a border with their own pages are Freiburg, Germany (about 87 km), Strasbourg, France (about 148 km), Stuttgart, Germany (about 164 km).

Delator Group is built for cases that cross borders. One case lead owns the matter from the first call to the final report, coordinates network investigators and licensed partners in each country involved, and keeps evidence handling, reporting format and deadlines consistent from one jurisdiction to the next. Time zones, translation and the rules on moving personal data between countries are planned into the scope rather than discovered halfway through.

Common examples: a family matter where one parent has moved from Zurich to another country, a distributor in Switzerland that is secretly owned by a competitor abroad, payments diverted to accounts in several countries, and stolen data offered for sale far from where it was taken.

• One case lead and one written plan for every country involved
• Licensed or registered partners for private investigation work in each country
• Consistent evidence handling and report format
• Translation, time zones and data transfer rules planned in advance
• Delator consultants for the corporate, cyber and testing elements in every country

08Credentials

Who Works on Your Zurich Matter

Delator Group's consultants come from the places where investigations are hardest. The team includes people with U.S. military intelligence backgrounds, people who served with the U.S. Department of Homeland Security, former law enforcement officers of every kind, former bounty hunters and technology experts across every discipline that cyber and physical security work demands.

Behind the core team sits a network that reaches across Switzerland and well beyond it, with investigators and specialists holding just about every credential a case can call for. For a client in Zurich, that means the person on your matter is chosen for the skill it needs, not for being the only option available.
