Trust is the hottest currency in the digital world—and it’s in short supply.
$10 million lost to a phishing scam. $250 million drained in fraud. $23 billion in identity theft losses.
Headlines like these have become the daily norm.
Trust, once an unspoken assumption, has now become a commodity, scarce and increasingly dangerous to give away. And blind trust has become a liability no organization can afford.
Why Zero Trust is No Longer Optional
Most transactions today happen remotely. Deals close across borders. Signatures are exchanged between people who’ve never met—and may never meet.
In this new landscape, trust is the currency that can make or break a business.
But with cybercriminals evolving faster than ever and a new victim every 22 seconds, that trust is in critically short supply.
This tension between necessary digital interactions and growing security threats has catalyzed the need for a fundamental shift in how organizations ensure the integrity of their digital workflows.
2025 will see synthetic identity fraud break out and become a substantial – and growing – challenge. The tools and technologies that fraudsters can leverage to create hyper-realistic synthetic identities are becoming cheaper and more readily available. At the same time, bad actors are becoming increasingly skilled. - Daniel Flowe Head of Digital Identity, LSEG Risk Intelligence
The old approach of building stronger walls needs to give way to a more sophisticated strategy: "Never trust, always verify."
This is the mantra that sits at the heart of Zero Trust Architecture (ZTA), a framework that’s revolutionizing how organizations protect their most valuable digital processes.
Though often discussed primarily as a network security model, Zero Trust is a concept that can—and should—extend to all areas of digital interactions to enhance security.
E-signatures, for example, are a critical point where Zero Trust principles can significantly enhance security. But before we dive into that, let’s first understand what exactly Zero Trust is.
Understanding Zero Trust Architecture
Defined as “a security model based on the principle of maintaining strict access controls and not trusting anyone by default, even those already inside the network perimeter”, Zero Trust means you have to prove you belong before gaining access.
You don’t get a free pass, not even if you’re a regular.
To truly understand Zero Trust, you need to know these core principles that drive this approach:
Verify explicitly - Always authenticate and authorize based on all available data points – identity, location, device health, service or workload, data classification, and more. ✅ In short: Make sure you have ALL the facts before allowing access.
Use least privilege access - Grant users only the specific access they need, just when they need it, limiting exposure in case of compromise. ✅ In short: Give just enough access to prevent misuse.
Assume breach - Pretend as if a breach has already occurred. Verify end-to-end encryption, use analytics to improve threat detection, and split up access so the damage stays low. ✅ In short: Always assume things might go wrong and set up defenses to handle it.
As a result, Zero Trust is all about relentless, real-time verification at every turn and constant vigilance.
When it comes to e-signatures, this translates to validating every step of the signing process from user authentication to document access to ensure that only the intended signer can interact with the document.
How Secure are Standard E-Signatures Against Cyber Threats?
Traditional e-signatures fall dramatically short of Zero Trust standards, creating security vulnerabilities that attackers can easily exploit.
Most conventional e-signature solutions rely on "single-factor authentication".
Typically email access or a simple password entry is enough for the system to implicitly trust that whoever possesses these credentials must be the authorized signer.
This assumption directly contradicts Zero Trust's core principle of "never trust, always verify."
Once initial access is granted, traditional e-signature platforms rarely verify continuously.
Anyone with access to your email can potentially sign documents on your behalf. Phishing attacks can trick users into signing documents without full awareness of what they're authorizing. And proving who actually clicked "sign" after the fact can be challenging.
Conventional e-signatures like typed names, uploaded images, or even basic drawn signatures can also be reused, copied, or created without the actual signer's knowledge, offering little protection against account takeovers or session hijacking.
Yet transactions must continue. Contracts must be signed. Authorizations must be granted. The wheels of business cannot stop turning simply because traditional signing models have failed us.
Video-based e-signatures represent the next evolutionary step.
How Do Video E-Signatures Work?
By recording live video of signers during the signature process, video-based signature systems capture multiple authentication factors simultaneously:
Visual confirmation of the signer's identity
Tacit acknowledgment of understanding and intent
Contextual metadata (timestamp, location, device information)
Behavioral biometrics through natural interactions
This creates a multi-layered evidence package that's significantly harder to forge or dispute than traditional e-signatures.
It's not just about capturing a signature. It's about documenting the entire signing event with irrefutable proof of who, when, where, and why.
How Video E-Signatures Embody Zero Trust Principles
1. Verify Explicitly
In a Zero Trust environment, implicit trust is eliminated.
Video-based e-signatures excel at explicit verification by combining multiple authentication factors in a single process. The signer's face, voice, intentions, and digital footprint create a comprehensive verification package.
Beyond basic identity validation, video signatures also capture nuanced elements like body language, environment, and verbal statements. These are contextual clues that can indicate duress or confusion that might invalidate consent.
This holistic approach to verification aligns perfectly with Zero Trust's emphasis on making security decisions with maximum available data points and context.
2. Assume Breach
Zero Trust operates on the assumption that breaches will happen. The question becomes: what safeguards remain when e-signature credentials are compromised?
This is where video e-signatures stand out. Even if a user's account credentials are stolen, producing a convincing video forgery remains exponentially more difficult than simply entering stolen password information.
Advanced systems can incorporate liveness detection to prevent the use of pre-recorded videos or deepfakes too.
Furthermore, the video records themselves serve as powerful forensic evidence after suspected breach events.
If fraud is alleged, investigators have rich contextual information to analyze rather than just server logs showing that "someone" authenticated successfully.
3. Continuous Authentication
One of Zero Trust's most transformative principles is the shift from one-time authentication to continuous verification. Video e-signatures support this by creating distinct verification events at each critical transaction point.
Unlike a traditional signature that might be copied from one document to another, each video signature is a unique event tied to a specific transaction at a specific moment.
This means every action requires fresh proof of identity and intent – exactly the kind of continuous verification that Zero Trust demands.
4. Least Privilege Enforcement
Modern video signature platforms like SelfieSign provide granular controls around who can initiate or complete video signatures for different types of transactions.
Role hierarchies and permission structures allow organizations to establish multi-tiered access systems, where signing rights match job duties and risk levels.
Admins can define custom roles with specific permissions, determining who can create documents, request signatures, or approve specific document types or transaction values.
For high-value contracts, you can enforce workflows requiring sequential video signatures from multiple organizational levels.
Likewise, you can also control who can access signed documents, verify signature authenticity, and audit the process.
The whole system adapts to your company's structure, making sure everyone has exactly the access they need without creating security gaps. This is Zero Trust's "least privilege" concept in action.
Which Industries are Benefitting the Most from Video E-Signatures?
Today, video e-signatures have already started to transform security practices across industries:
Financial services institutions are using video signatures to prevent wire transfer fraud and authenticate high-value transactions, creating an audit trail that dramatically reduces dispute resolution time.
Legal firms are employing video signing for sensitive agreements, ensuring clients fully understand terms and providing courts with comprehensive evidence of proper execution.
Healthcare providers are meeting strict compliance requirements for patient consent with video documentation that proves both identity and comprehension of medical procedures.
Human resources departments are securely onboarding remote employees by creating verified digital identity packages, reducing impersonation risks in distributed workforces.
Why Should Businesses Implement Video-Based E-Signatures?
Much like upgrading from a flimsy lock to a smart security system, video-based e-signatures offer other compelling benefits that go well beyond just keeping the bad guys out.
Here are some of their other advantages:
Regulatory compliance becomes more straightforward when you can demonstrate comprehensive verification procedures with video evidence.
Many regulations already require stronger authentication for sensitive transactions, and video signatures provide robust evidence of compliance.
Customer trust improves when people see organizations taking visible steps to protect their transactions.
The psychological impact of knowing a video record exists tends to increase accountability while reducing both fraudulent attempts and false claims.
Dispute resolution accelerates dramatically when video evidence exists.
What might have previously required extensive investigation or even litigation can often be settled immediately by reviewing the signature video.
Perhaps most importantly, video e-signatures future-proof your security infrastructure against evolving threats.
As authentication standards continue to tighten, organizations with video verification already in place will find themselves ahead of both regulatory requirements and criminal techniques.
