Below is our recent interview with Brian Hajost, Principal at VeraSec Technologies:
Q: Could you provide our readers with a brief introduction to VeraSec Technologies and VeraFile?
A: VeraSec Technologies is a cybersecurity company focused on a problem that has been largely overlooked: how do you preserve trust in a file after it leaves the infrastructure that originally protected it?
Cybersecurity has become very good at protecting users, devices, networks, applications, and repositories. But files constantly move beyond those boundaries—through email, cloud platforms, partners, archives, removable media, and increasingly AI-driven workflows. When that happens, much of the security context surrounding the file can disappear.
We created VeraFile to give the file itself a persistent, portable identity. VeraFile uses a compact Validation Integrity Key, or VIK, to cryptographically bind a file’s contents, filename, selected metadata, and validation policy into a verifiable identity that travels with the file.
Our objective is simple: every file should be able to prove what it is, wherever it goes.
Q: What makes VeraFile different from existing file-integrity technologies?
A: VeraFile is not intended to replace cryptographic hashing or PKI digital signatures. It adds something those technologies generally do not provide on their own: a persistent, portable identity for the file itself.
A cryptographic hash is very effective at answering one question: Have these bytes changed? But the hash is separate from the file, so an organization must securely maintain both the hash and the trusted relationship that proves which hash belongs to which file. In higher-assurance workflows, the file and its hash may also be transmitted or verified through separate trusted channels, creating additional operational complexity. Even after delivery, that association must remain intact as the file is copied, moved, archived, or retained for years.
PKI digital signatures solve a different problem. They can establish that signed content has a valid cryptographic signature, but the external filename is generally not part of that signature. A file can be renamed without invalidating the signature, and one properly signed file can potentially be substituted for another if the surrounding workflow does not verify that it is the specific file expected.
VeraFile adds another layer: Portable File Identity. It cryptographically binds the file’s contents to its filename and other selected attributes, creating a validation identity that travels with the file itself. Instead of relying entirely on external infrastructure to maintain the relationship between a file and its integrity information, VeraFile makes that relationship portable and independently verifiable wherever the file goes.
Hashing protects content. PKI validates signatures. VeraFile adds persistent identity to the file itself.
Q: You recently received a U.S. patent. Why is that significant?
A: On September 29, 2026, the USPTO issued VeraSec U.S. Patent No. 12,750,232, “Immutable Document Sealing and Authentication.”
The patent protects foundational concepts around cryptographically linking file integrity with filename identity and later authenticating that relationship.
For us, the patent is important validation of the underlying invention, but I believe the larger opportunity is what can be built on top of it. We have already filed a continuation patent application seeking additional protection for expanded implementations of the VeraFile architecture.
The broader idea is that the filename has historically been treated as little more than a label. We believe it can become part of the security control framework itself.
Q: Why is Portable File Identity especially important now?
A: The volume of digital information being created is exploding, and AI is accelerating that dramatically.
Increasingly, files are not created by a person sitting at a keyboard. They are created automatically by AI systems, applications, security platforms, sensors, business systems, and other machines.
Traditional integrity technologies tend to be applied selectively because signing files or maintaining external hash infrastructures creates significant operational friction.
VeraFile is being engineered around a very different goal: make integrity protection frictionless and scalable enough that organizations can protect virtually every file, not simply a small percentage of particularly sensitive ones.
As machines increasingly create information that humans and other machines rely upon, knowing whether a file is still exactly what it claims to be becomes increasingly important.
Q: Who can benefit from VeraFile?
A: The potential applications are extremely broad because virtually every person or organization relies on files.
Enterprise use cases include financial records, contracts, compliance evidence, software, security logs, transaction records, AI-generated information, images, video, and intellectual property.
There are particularly compelling applications in government and defense, healthcare, law enforcement, legal evidence, financial services, critical infrastructure, software supply chains, and scientific research, where decisions may depend on proving the integrity of 3rd-party information long after it was created.
Publishers and consumers of digital information can also benefit. We increasingly live in a world where seeing a document, photograph, video, or data file does not necessarily tell us whether it is authentic or whether it has been altered.
Ultimately, anyone who must make a decision based on a digital file benefits from the greater confidence in that file provided by VeraFile.
Q: What is your vision for VeraFile over the next several years?
A: We want Portable File Identity to become a standard component of cybersecurity infrastructure.
Zero Trust changed the industry’s thinking by establishing that users, devices, applications, and networks should not automatically be trusted simply because of where they are located. We believe that principle should extend to files.
VeraFile is being designed for integration into operating systems, enterprise software, cloud platforms, productivity tools, cybersecurity products, AI environments, and high-assurance government systems.
Our business model is primarily technology licensing. We are interested in working with infrastructure providers, software companies, cybersecurity vendors, AI companies, government organizations, and strategic partners that manage large populations of digital files.
The long-term opportunity is much larger than a standalone cybersecurity product. We believe Portable File Identity can become a new security layer for digital information.
Q: What is something about VeraFile that people may not immediately appreciate?
A: One of the most interesting aspects is long-term integrity.
Think about an important file 10 or 20 years from now. The file may still exist, but will the original application exist? Will the signing certificate still be valid? Will anyone know where its hash manifest is stored? Will the infrastructure that originally established its integrity even exist?
Important files often outlive the systems that created them and the infrastructures that stored them. That is why we believe integrity should travel with the file itself.
The goal of VeraFile is not simply to determine whether a file is trustworthy today. It is to help preserve the ability to answer a much more fundamental question years or decades into the future:
“Is this still the file it claims to be?”
