Your Plan B Justice Solution, When Law Enforcement Can’t Help.
Rexxfield investigates complex cybercrime cases. We are here to help you get justice.
We identify anonymous offenders, trace stolen digital assets, and support law enforcement and civil law teams with evidence that holds up in court.
Since 2008, we’ve worked with victims, corporations, law firms, and law enforcement worldwide to deliver fast, discreet, and proven outcomes in complex online cases.
From harassment and impersonation to defamation, we identify those responsible and gather evidence for legal or law enforcement action. We trace trolls through anonymous phone numbers, email addresses, social media, websites, etc.
We investigate and trace online scams involving financial fraud, romance deception, and stolen digital assets. We trace assets, identify scammers, and work with exchanges and law enforcement agencies around the world to support recovery and prosecution.
We undertake each romance scam investigation case-by-case, listening carefully to your story to develop a plan using scammer engagement, investigative tools and intelligence partners to trace, unmask and recovery your assets.
Our cyber investigators gather evidence to stop anonymous social media accounts from harassing you. In most cases we identify the IP address and personal information of the profile owner, and rule in / out suspects. Additionally, we provide actionable intelligence for police or legal action.
Online defamation is often part of a broader smear campaign against individuals or businesses. We help clients find all mentions of defamation, build a case of proving online defamation and identify who is responsible for the smear campaign to sue for damages in court.
We combine the latest in digital forensic techniques with deep legal knowledge to uncover, prove, and assist with the recovery of hidden cryptocurrency and other digital assets in divorce cases.
We trace stolen assets across borders, freeze funds where possible, and counter-engages to locate the perpetrators. We work directly with banks, crypto exchanges, and international law enforcement to bypass bureaucratic delays and accelerate case progress.

Within only a couple of days, Rexxfield discovered the identity of the cowardly “anonymous” owner of a website, which he created to discredit and defame me. I was then able to file a lawsuit against him.

The police did not know what to do about my stalker. For 7-months I had no help, or hope of a rescue. Michael from Rexxfield ID’d the stalker within 2 days. He wrote a report and step by step instructions for the police to follow for prosecution. I now have a restraining order..

Michael is reliable, trustworthy, and delivers what he promises. I’m very glad to have Michael on my side.

Rexxfield is the most qualified company for any business or individual in need for reputation management services, search engine optimization or forensic investigation services. The people in Rexxfield’s team are not just the best, in terms of talent, but they also genuinely care about their clients. Most people (and businesses) who’ve been defamed, harassed and/or stalked online, or are a victim of online identity theft, feel victimized and alone. The professionals at Rexxfield provide victims with a sense of empowerment. They are available 24-hours a day. There is NO other firm that I’d recommend or use myself for SEO or reputation management, other than Rexxfield.

I have worked with Rexxfield on multiple occasions regarding a variety of cyber-investigative matters. Rexxfield has always proved to be extremely knowledgeable, resourceful, innovative, quick-acting, and results-driven. I continue to turn to Rexxfield first for my cyber-investigative needs, and I have referred Rexxfield to many others.

I hired Rexxfield after receiving hundreds of harassing and cruel anonymous text messages for 18 months. The police were unable to help me; I felt afraid and desperate for help. Rexxfield identified who my harasser/cyber-stalker was: it was my husband. Along with Rexxfield’s investigation evidence, they assisted me with gathering additional legal evidence pertaining to their investigation, during my 18-month long divorce litigation, to create an even stronger case. During my litigation I fought for primary custody of my children, and was granted primary custody, of which Rexxfield’s evidence of my husband being the anonymous texter was a huge factor in the judge’s custody decision.
I searched through several private investigators before deciding on Rexxfield, as I have learned that very few PIs can actually do this type of investigation. Considering all Rexxfield provides, their prices are extremely reasonable and they genuinely care about your case. Along with their ability to obtain conclusive evidence, Michael, owner of Rexxfield, is an excellent testifier and has top-notch credentials. My attorney was pleased.
I don’t know what my children and I would have done without Rexxfield’s help.

I asked for help from Rexxfield after local law enforcement and prosecutors refused to investigate the social media used by an individual who had been threatening my family and me . Rexxfield completed their investigation swiftly and discreetly. They maintained regular contact with us and were always available and interested in helping us. Frankly, they gave a d*mn, and my wife and I needed that. Rexfield’s findings made me realize that we were in more danger of firearms violence from this individual than I had even imagined. The information they compiled is now an important part of the criminal and civil suits soon to take place. I will always be grateful for the assistance Rexxfiled provided.

Rexxfield is there for you in your time of need. You are much more than just a “client” to Rexxfield, they take a personal interest in your story and work with you to resolve the problem. I have tried other “reputation management” companies and was not impressed. It seemed as if they were only out to take my money and could really care less if my reputation management problem was solved or not. I would highly recommend Rexxfield to anyone who has a reputation management problem.
