Is Synthesia safe?
Yes, Synthesia is safe to use. It holds SOC 2 and ISO 42001 certifications and is GDPR-compliant, encrypts data, requires live consent to create any avatar, and moderates content. In an October 2024 NIST-aligned red-team test, it blocked all 40+ attempts to make non-consensual avatars and rejected 74 of 75 harmful scripts.
Why — the first-principles explanation
'Safe' for an AI video tool splits into two questions: is my data safe, and can the tool be used to harm others (deepfakes)? Synthesia addresses both by design.
For data safety, the relevant proof is third-party audits. SOC 2 checks that security controls (access, encryption, monitoring) actually work; ISO 42001 covers responsible AI management; and GDPR compliance governs how personal data is handled. These aren't self-declared, an outside auditor verifies them, which is why enterprises trust the platform with employee footage and internal content.
For misuse safety, the key mechanism is consent plus moderation. You can't clone a face without a live consent video reading an on-screen passcode, and pre-recorded consent is rejected, so a bad actor can't upload a stranger's or celebrity's footage. On top of that, submitted scripts pass through automated and human content moderation across policy areas like fraud, hate, and medical misinformation.
The strongest evidence is an independent stress test. In October 2024, security experts ran a NIST-aligned red team against Synthesia. It blocked 100% of the 40+ non-consensual avatar attempts and rejected 74 of 75 harmful scripts, one medical-misinformation video slipped through, prompting an internal fix. No system is perfect, but a near-miss rate that low under expert attack is a meaningful safety signal, not marketing.
The residual risk is ordinary: like any cloud tool, don't upload data you're not allowed to, and follow your organization's policies. The platform is safe; how you use it still matters.
An example that makes it click
Think of a bank vault with two kinds of safety. First, the building itself is secure, cameras, alarms, and an inspector who signs off that the locks work (that's SOC 2, ISO 42001, GDPR). Your valuables inside are protected.
Second, the bank won't let just anyone open a safe-deposit box in your name, you have to show up in person with ID (the live consent video). And they hired testers to try breaking in: those testers made 40-plus attempts to open boxes they shouldn't, and every single one was stopped. That combination, a secure building plus a strict ID desk that passed a break-in test, is why Synthesia counts as safe.

Is Synthesia safe? Yes, and 'safe' really means two things: is your data protected, and can the tool be abused to make deepfakes? On data, Synthesia holds SOC 2 and ISO 42001 certifications and is GDPR-compliant, and those are verified by outside auditors, not self-declared, which is why big companies trust it with internal footage. On misuse, the key safeguard is consent plus moderation. You can't clone a face without recording a live consent video reading a passcode on screen, so nobody can upload a stranger's or a celebrity's video. And every script passes automated and human content review. The strongest proof is an independent test. In October 2024, security experts ran a NIST-aligned red team against Synthesia. It blocked every one of the forty-plus attempts to make non-consensual avatars, and rejected 74 of 75 harmful scripts. One slipped through and was fixed. No tool is perfect, but that's a strong safety record. Just follow your own organization's data rules when you use it.

People also ask
Is my data safe with Synthesia?
Yes. Synthesia is SOC 2 and ISO 42001 certified and GDPR-compliant, with encryption and access controls audited by third parties. Still follow your own organization's rules on what you upload.
Can someone make a fake video of me on Synthesia?
Not easily. Creating an avatar requires a live consent video reading an on-screen passcode, and pre-recorded consent is rejected, which blocks cloning someone's face without permission.
Has Synthesia been independently tested for safety?
Yes. An October 2024 NIST-aligned red team blocked all 40+ non-consensual avatar attempts and rejected 74 of 75 harmful scripts, with the one miss prompting an internal fix.
What content does Synthesia block?
It moderates categories such as fraud and scams, hate speech, graphic violence, illegal activity, and medical misinformation, using both automated systems and human reviewers.
