Deepfakes Are Coming for Your Company: A Founder's Briefing
Published · By Thiago Vieira · 3 min read · Cybersecurity
Deepfakes are already a business risk, not a future one. Cloned voices, synthetic video and forged documents are used to authorize payments, pass identity checks and fabricate evidence. Founders do not need to become experts, but they do need verification rules and a plan.
How deepfakes hit companies
- Executive impersonation. A "CEO" voice message or video call asks finance to make an urgent transfer.
- Synthetic identities. Fake documents and faces used to open accounts or pass onboarding.
- Fabricated evidence. Manipulated screenshots, audio or video submitted in disputes.
- Reputational attacks. A fake video of a founder saying something damaging, released at the worst moment.
How forensic experts examine suspicious media
From my work as a court-appointed digital forensic expert, one lesson stands out: no single tool decides. An examination combines several layers:
- Provenance and metadata: where the file came from, how it was created and whether that story is consistent.
- File structure: container, codec and compression traces that reveal editing or generation.
- Visual and audio artifacts: inconsistencies in lighting, lip movement, breathing, background noise and spectral patterns.
- Context: does the content match what is known about the people, place and time?
Courts increasingly expect this kind of documented methodology, not just a detection score.
What founders should put in place now
- A payment verification rule. Any unusual or urgent request is confirmed through a separate, known channel. No exceptions for "the CEO".
- Code words or call-back procedures for high-risk approvals.
- Training that uses real examples, so people recognize pressure tactics.
- Permission to pause. Employees must feel safe saying "let me verify".
- Evidence preservation. If you suspect a deepfake, keep the original files and messages; do not just forward screenshots.
- A response plan for reputational fakes: who speaks, how you prove it is fake, which experts you call.
Digital immunity
In my TEDx talk I describe this as building digital immunity: the human habit of pausing, checking and sharing before acting. Technology helps, but culture is the first line of defense.

I cover these cases in two keynotes: Forensic Challenges in Real-World Cases of Digital Manipulation and How to Create Digital Immunity Against Scams. Both work for executive teams, founder events and security conferences. Book a keynote.
Frequently asked questions
How are deepfakes used against companies?
Common uses include impersonating executives on calls or voice messages to authorize payments, fake identity documents in onboarding, manipulated evidence in disputes and reputational attacks with fabricated videos.
Can deepfakes be detected?
Often, but not with a single tool. Forensic examiners combine metadata and provenance analysis, file structure and compression artifacts, audio analysis and context checks. Detection tools alone are not enough.
What is the best protection against deepfake payment fraud?
Process, not technology: a verification rule that any unusual payment request is confirmed through a separate, known channel, plus a culture where employees are allowed to pause and check.
Does Thiago Vieira cover deepfakes in his talks?
Yes. His keynote on forensic challenges in real-world digital manipulation and his TEDx talk on digital immunity both address deepfakes and social engineering.
