Zero Trust Fatigue: When "Never Trust" Becomes "Always Slow"

SHILPI MONDAL| DATE: FEBRUARY 06, 2026

You know the drill, right? You're in the zone, just really getting into finalizing a critical report or ironing out a tricky problem when, ping! Another multi-factor authentication request shows up in your phone. You approve it and get back to work. Then, ten minutes later? You get kicked out of the system and have to log in again.

It's maddening. But here's what's worse: it's actually creating security risks. Look, the industry made the right call moving away from those old "castle-and-moat" defenses toward Zero Trust Architecture. No question about it. But somewhere along the way, we hit a problem. That whole "never trust, always verify" philosophy? It's accidentally created something new to worry about: Zero Trust Fatigue.

Here's what that looks like in practice. All those mechanisms we put in place to protect ourselves-the constant re-authentication, the restrictive permissions, the granular access controls-they're starting to work against us. They're killing productivity. And when security becomes this big frustrating barrier, employees don't just sit there and complain about it. They find ways around it.

The Architecture of Frustration

To understand the fatigue, we have to look at how we got here. Historically, we relied on perimeter defenses firewalls that acted like a moat around the corporate castle. Once you were inside, you were trusted. But as NIST's Zero Trust Architecture guidelines highlight, this model crumbled under the weight of cloud computing, remote work, and mobile devices. The perimeter is gone. Zero Trust stepped in to fill the void, assuming that threats exist both inside and outside the network. It’s a necessary evolution. However, implementing this often introduces "friction"-technical challenges that prevent employees from doing their jobs efficiently.

Take Multi-Factor Authentication (MFA). It's vital for stopping credential theft, but it has a breaking point. Attackers are now exploiting our psychological exhaustion through "MFA fatigue" or "push bombing." In these scenarios, a threat actor with stolen credentials spams a user with push notifications. As noted by Fortra's analysis on MFA risks, frustrated users often approve the request just to make the notifications stop, inadvertently handing the keys to the kingdom to the attacker. It’s a strategic paradox: the more often we ask for verification, the less attention users pay to it.

The High Cost of "Computer Says No"

The impact of this friction isn't just a few grumbles at the water cooler; it’s a measurable drain on the bottom line. When security protocols interrupt workflows, the costs compound quickly.

According to TeamViewer’s report on the impact of digital friction, the average global employee loses 1.3 workdays every month due to technical dysfunction and security interruptions. In high-pressure environments like India and the US, that number climbs even higher.

But lost time is just the tip of the iceberg. The same report found that 42% of organizations cited direct revenue loss due to technical dysfunction, while 37% reported losing customers. When your best people are fighting to get to the login screen, rather than having the freedom to innovate, the competitive edge blunts. The window for creativity is limited, and for every minute spent fighting to get past a complex access policy, a valuable minute is lost.

Shadow IT: The Path of Least Resistance

When the “front door” is shut through too many deadbolts, employees just go in through the windows. This, in a nutshell, is the rise of Shadow IT. Well-meaning employees just doing their job are creating unauthorized applications and workflows.

It’s not done out of malice, it’s done out of pragmatism. If the formal means of secure file transfer is inconvenient, a group may decide to use members' Google Drives/Dropbox as a means of fulfilling the assignment. As Wiz's research on Cloud Security points out, these unmanaged assets create massive blind spots for IT teams.

The risks here are severe. Regulators have fined financial firms-including broker-dealers, investment advisers, and credit-rating agencies. According to off-channel communications hundreds of millions to billions of dollars for failing to properly retain and supervise employee communications conducted on unauthorized messaging apps such as WhatsApp, Telegram, and Signal, a common form of Shadow IT that arises when secure but restrictive systems frustrate workers.

Eroding the Psychological Contract

There is a softer, human side to this technology shift that often goes ignored. Every employment relationship is built on a "psychological contract"-the unwritten expectations of mutual trust.

When an organization aggressively adopts a "never trust" stance without proper context, it sends a signal: We don't trust you. Research published in the ISACA Journal on the consequences of Zero Trust warns that this can dismantle the "Ability, Benevolence, and Integrity" (ABI) trust model. If employees feel viewed primarily as potential threats, they become less committed to the organization’s security goals. It creates a "virus" of oversight where the workplace feels impersonal and isolated.

Good security isn't just about locking things down it's about trust. If you treat employees like they're the threat, don't be surprised when they stop caring about protecting the company. People who feel respected act like partners. People who feel suspected check out.

The Solution: Adaptive, Intelligent Verification

So, do we abandon Zero Trust? Absolutely not. The threat landscape is too hostile for that. Instead, we need to evolve from static Zero Trust to Adaptive Zero Trust.

The future is looked at as being in the category of Risk-Based Authentication (RBA). In this category, rather than every attempt to log in being considered suspicious, decisions are being made in the background. The premise is explained in the guide put up by Entrust on the process of RBA, in which the process analyzes the device, location, and reputation of the network.

Scenario A: 

An employee logs in from their corporate laptop, at the main office, during normal hours. Result: Zero friction (seamless access).

Scenario B: 

Now, the same employee attempts to log in from an unfamiliar device in a different country at 3 a.m. Result: High friction (biometric challenge or one-time code).Your computer can actually tell it's you just by watching how you type and move your mouse around. Everyone has their own style maybe you type fast but pause between certain words, or you have a particular way of scrolling. These little patterns add up to something totally unique to you.

The cool part? It happens automatically. You don't have to stop and punch in a password or wait for a text with a code. You're just doing your thing, and your computer's quietly going "yep, that's them" in the background. It's authentication that doesn't get in your way.

According to Cyber Defense Magazine, AI-driven controls can reduce policy misconfigurations by 32% and cut false positives by 41%. What does that actually mean? Regular users hit fewer frustrating roadblocks, and security teams don't have to waste their time chasing down alerts that turn out to be nothing.

Making Security a "Team Sport"

Technology alone won't solve fatigue. We need a cultural reset. CISA's Zero Trust Maturity Model suggests that moving to an "Optimized" stage requires full leadership buy-in and a shift in how we talk about security.

Leaders need to communicate the why behind the what. Instead of just mandating a new MFA tool, explain how phishing-resistant protocols protect the company's reputation—and by extension, everyone's jobs. As noted by The Grossman Group's strategy on internal comms, linking security objectives to business outcomes is crucial for alignment.

We can even use "intentional friction" strategically. As discussed in Medium's analysis of security UX, sometimes a brief pause or animation during a high-stakes transaction can actually reassure users that their data is being protected, provided it doesn't happen every five minutes.

The Way Forward

While the model for Zero Trust is here to stay, growing to a market potential of over $84 billion by 2030 according to Grand View Research, it won’t be the organizations with the most stringent policies that succeed in the field it will be those who finally figure out how to make security invisible within the enterprise.

By using AI, improving the user experience, and treating employees like partners instead of potential threats, we can change the whole dynamic. Security doesn't have to be the thing that slows everyone down-it can actually help people do their jobs better. It's time to stop making our own teams jump through hoops and start focusing on the actual bad guys.Ready to move beyond Zero Trust fatigue?
