What does a cyber investigator do?
A cyber investigator identifies who is behind online harassment, defamation, fraud and scams. We combine open-source research, technical analysis and support for legal process, then deliver a report you can use with your attorney, your bank or law enforcement. We can identify anonymous attackers even when they hide behind a VPN, as long as there is a suspect.
Speed matters. The earlier we start, the more evidence we can preserve.

Case study
Proven on a very public case: BrewDog co-founder James Watt
James Watt was the target of an online smear campaign, and the person behind it hid behind VPN cloaking services. Rexxfield identified them anyway. Mr. Watt chose to go public with the case, and it was covered by the press.

Common questions
Hire a cyber investigator: common questions
What does a cyber investigator do?
A cyber investigator identifies who is behind online harassment, defamation, fraud and scams. We combine open-source research, technical analysis of emails, accounts, domains and transactions, and support for legal process, then deliver a report you can use with your attorney, your bank or law enforcement.
How much does it cost to hire a cyber investigator?
The fee depends on the type of case. Digital investigations start at a minimum of USD 5,000 and corporate investigations at a minimum of USD 10,000. We send a clear scope and quote before work begins, after a free, confidential consultation. See our fees page.
Can a cyber investigator recover stolen money?
We trace where the funds went and prepare evidence for banks, exchanges and law enforcement. We cannot promise recovery. Speed matters, so contact us as soon as you notice the loss.
Can you identify an anonymous person online?
Often, yes. We can identify anonymous attackers even when they hide behind a VPN, as long as there is a suspect. We state how confident each finding is, and we tell you plainly when the evidence cannot get to a name.
Do cyber investigators hack accounts?
No. We use lawful methods only. Evidence gained by hacking would harm your case, and anyone who offers to hack an account or device puts you at risk.
Is the first conversation confidential?
