People in an organization may first hear the phrase “Zero Trust” in a slide deck about security. It certainly sounds clean, logical, and relatively straightforward. However, when those same people try to apply Zero Trust in a real-world environment, the complexity quickly becomes apparent.
“The reason Zero Trust can trip up some organizations is that, in practice, Zero Trust isn’t a product to deploy or a switch to be turned on,” noted John Tkaczewski, Senior Solutions Architect, Fortra MFT. “Instead, it is a series of deliberate decisions about what should no longer be trusted by default, and how much friction an organization is willing to introduce to reduce risk to the data entrusted to them.”
The Perimeter is No More
Zero Trust file transfer emerged because traditional security models still assume there’s a clear “inside” and “outside” — with the thinking that if the edge is protected, firewalls are locked down, and VPNs are monitored, you’re covered.
Unfortunately, that line of thought hasn’t matched reality for years. The touchpoints for often-sensitive data have changed and expanded.
Today, people work from coffee shops, vacation homes, or in the home office. Systems now live within in-house and peripheral data centers as well as on cloud platforms. In addition, vendors and partners may now plug directly into internal workflows.
And with automation running nonstop, all that data often moves behind the scenes with credentials that no actual person ever sees.
When everything is interconnected like this, assuming anything is “safe” just because it’s internal is how problems start. Zero Trust is an acknowledgement that this reality exists and seeks to minimize that risk in practice.

Zero Trust Isn’t Elegant. It’s Restrictive by Design.
On paper, the refrain “never trust, always verify” sounds simple. In real environments however, it can be inconvenient. Zero Trust forces organizations to consider uncomfortable questions, such as:
- Does this user actually need this level of access?
- Should this workflow really be able to touch that system?
- What happens if this credential gets exposed?
“The answers to these questions usually result in organizations taking the necessary steps to lock down processes and workflows that may have been free-floating for years because of responses like, ‘it’s always worked’ or ‘we don’t want to break anything,’” said Tkaczewski. “Attackers are counting on that comfort and convenience that’s been in place, and that’s a risk that Zero Trust conversations address.”
Zero Trust usually means that the standard way of doing things will now look different. Users might be required to use an authenticator app, or file transfers may take longer because they are scanned for malware and viruses, or because additional user verification is required before opening sensitive files.
These may be small “inconveniences” to the end users, but they are well worth it to prevent the wrong data falling into the hands of bad actors.
“IT departments need to do a better job communicating with their end users as to ‘Why we are changing and evolving.’ Too often, they do not take enough time to explain the solid security reasons behind the changes and why Zero Trust is being implemented,” added Tkaczewski.
User Logins Aren’t the Risk; It’s Automation Without Intention
Zero Trust conversations tend to fixate on users: identity providers, MFA, device trust. Of course, those all matter. But they’re only half of the story.
A huge amount of sensitive data moves without a person clicking on anything: automated file transfers. scheduled jobs, APIs, and service accounts that never expire because everyone’s afraid to rotate them.
Those systems are trusted precisely because they are quiet and sit in the background. And when something goes wrong with them, it’s often not noticeable in a timely fashion.
Automation itself isn’t the enemy of Zero Trust, but uncontrolled or undisciplined automation certainly can be. Many organizations depend on automation to operate at scale, and eliminating it isn’t realistic. Zero Trust instead forces organizations to be explicit about how exactly automation is allowed to operate, such as establishing clear limits around what automated processes can access, where data is allowed to move, and how that activity is verified.
Managed File Transfer (MFT) helps bring that discipline to automated data movement. Rather than letting scripts and scheduled jobs operate wherever credentials happen to work, MFT centralizes file transfers behind explicit, centrally managed policies. Automated workflows run with least privilege access, restricted destinations, and full audit trails, so that the needed automation is controlled without being fragile or error‑prone.
Verification Shouldn’t Stop at Login
One of the most common Zero Trust failures is assuming the job is done once access is granted — because that’s not how systems behave.
After all, credentials can get reused, and jobs can be repurposed. And over time, data flows change incrementally until someone notices something and it’s too late. Continuous monitoring needs to be about understanding what normal actually looks like in your environment so that abnormal behavior doesn’t get lost in all the noise.
“It’s important to remember that if you can’t actually see what’s happening, you’re essentially trusting that nothing bad is occurring, whether you mean to extend this level of trust or not,” added Tkaczewski.
That same principle applies to automated file transfers. When MFT is used to control file movement, organizations gain consistent visibility into how data is flowing and which systems are responsible. Changes in endpoints, timing, transfer volume, or access patterns become observable signals instead of hidden assumptions.
In more mature environments, this visibility can be strengthened with contextual threat intelligence. For example, integrating real-time IP reputation data at the MFT connection layer allows organizations to continuously reassess the trustworthiness of incoming connections. What does this mean? It means that “allowed” once does not permanently mean “safe always.”
This reinforces Zero Trust by introducing verification not just at login, but throughout the life of an automated process. Solutions, such as GoAnywhere’s Threat Brain, automatically and continuously check the IP reputation of connections and block any coming from suspicious IP addresses to add an additional layer of security.
Zero Trust Doesn’t Get Implemented All at Once
If an organization brags that they rolled out Zero Trust across the enterprise, be skeptical. They may have indeed had a very small environment, or their definition of success needs to be looked at more closely.
Rolling out Zero Trust is instead a matter of narrowing the scope:
- Start with high‑risk access.
- Lock down sensitive data paths.
- Reduce privileges where incidents would hurt the most.
For many organizations, automated data movement is an ideal starting point. File transfers often touch sensitive systems and external partners but operate with broad, inherited trust. Centralizing those flows through MFT allows teams to reduce implicit trust quickly and without unnecessarily disrupting end users or redesigning entire identity systems.
Each change chips away at implicit trust and limits how far damage can spread when something eventually breaks.

What Does Zero Trust Mean in MFT?
Zero Trust in a Managed File Transfer context means extending the same skepticism applied to user logins to every stage of file movement (who is accessing data, how is it handled, and what happens after it’s been shared?).
It starts with strong user verification. Multi‑factor authentication combined with single sign‑on ensures that access to file transfer systems is tied to verified identities, not standalone credentials or shared accounts. But Zero Trust does not stop once a user is authenticated.
Every file must also be treated as untrusted by default. That means scanning all files for malware or other threats, regardless of whether they originate from internal systems or external partners. Trusting a file simply because it came from a familiar source is a common—and costly—assumption that Zero Trust explicitly challenges.
And even when a file is sent to the correct recipient, Zero Trust asks another critical question: What happens next?
Highly sensitive data often doesn’t become exposed at the moment of transfer, but later, when it’s forwarded, copied, or shared beyond its intended audience.
This is where digital rights management (DRM) and secure collaboration controls supports Zero Trust principles by maintaining control over data after delivery. By ensuring only authorized users can view or edit a file and prevent unauthorized redistribution, organizations can reduce the risk that sensitive information spreads simply because access was granted once.
In practice, Zero Trust in MFT is about enforcing intent:
- Verifying identities before access
- Inspecting files before they move
- Controlling how data can be used after it arrives
Zero Trust Means Ongoing Work
Zero Trust should also follow your environment as it changes. As business pressure pushes for faster access and fewer checks, every environmental change can be a decision point: Do you allow convenience to win, or do you tighten control and accept there may be some friction as a result?
A resilient security posture is built by consistently refusing to assume trust where it hasn’t been earned, and by revisiting those assumptions when the environment shifts.
Putting Zero Trust into practice may not be easy or fast. But embracing it can make it much harder to exploit your environment.
Zero Trust succeeds when organizations stop treating automation as an exception to security rules and start governing it with the same rigor as user access. When automated data movement is intentional, observable, and continuously verified, it no longer represents hidden risk—it becomes part of a resilient security posture that can adapt as environments change.
MFT plays a key role in that shift by providing more clarity around: what data moves, why it moves, where it’s allowed to go, and under what conditions trust is reevaluated. Combined with visibility and contextual signals that help teams detect when behavior changes, automation can support Zero Trust goals instead of undermining them.
Explore how a modern MFT platform can supports Zero Trust by centralizing automated file transfers, enforcing least-privilege access, and improving visibility into data movement—all without breaking the workflows your business depends on.
