Human-centric security: Why your employees are your best defence against AI Deepfake fraud

Written by Aarti Samani, CEO, Shreem Growth Partners

Cybercrime is booming. We all know it. But while attack vectors are evolving by the minute, our security budgets are barely inching forward. This disconnect is creating a dangerous vulnerability, particularly with the rise of human-manipulation fraud, like AI-enabled deepfake. It is no longer just something that happens to celebrities. It is now an everyday reality, and a boardroom problem. My work in biometric security working with the public and private sector, has given me an insider’s view of how devastating it can be. 

Cyber criminals are leveraging the power of AI to clone voices, create realistic video impersonations, and mimic suppliers. They are tricking employees into approving multi-million dollar transactions, and unfortunately, it’s working. Remember the deepfake CFO who orchestrated a $25 million transfer over a Zoom call? That’s just one example of how sophisticated these attacks have become. 

Let’s look at some numbers to contextualise the problem. Cybersecurity budgets are creeping upwards – around 8% in 2024. The talent shortage is crippling, with 500,000 unfilled cybersecuri jobs in the US. Meanwhile, cybercrime is projected to cost a staggering $12 trillion in 2025. The math simply doesn’t add up. 

A legitimate business can only allocate a percentage of its budget to cybersecurity. Cybercriminals, on the other hand, dedicate 100% of their resources to committing fraud. They’re playing with a full deck. 

Yet, many companies are stuck in a reactive cycle: buy more tools, hire more specialists, run “check-box” training. It’s an unsustainable arms race. We’re throwing money in a bottomless pit, without results. 

The harsh reality check: We are in the cyber criminal’s trap 

I want to highlight 3 points to support my thinking: 

  • Defensive technology is constantly being outpaced: For every dollar invested in detection, criminals are investing a fraction to bypass it. Offensive technology is cheaper and mo readily available on the dark web, giving them a distinct advantage. 
  • Security teams are drowning in false alarms: The quest for hyper-vigilance is leading to a deluge of false positives, burning out analysts and creating alert fatigue. Real threats are getting lost in the noise. 
  • Compliance costs are eating up budgets: A significant portion of security spending  dedicated to documenting risks, leaving less for actual preventative measures. 

Cybersecurity spending has become a black hole. No matter how much we invest, attacks are still getting through. Why? Because criminals aren’t always hacking systems; they are hacking people. A well-timed email, a cloned voice note, a convincing deepfake Zoom call – if an employee believes it, no amount of security technology can stop them from acting on it. 

The solution: Building a fraud-aware workforce

If budgets are flat, security teams are stretched thin, and technology alone is not enough, what’s t answer? 

Well, how about we tap into our latent pool of salaried employees? What if we build a fraud-aware workforce, and empower every employee to become the secure gateway?

Deepfake fraud exploits human trust. But humans also possess the solution: critical thinking and pattern recognition, qualities that AI cannot easily replicate. A trained employee might notice subtle inconsistencies in a deepfake video – a lack of the CEO’s usual sarcasm, perhaps – and decide to proceed with caution. 

Employees are also a highly scalable defense. Instead of relying on a few experts, organizations need to equip everyone with the skills to spot and stop deepfake threats. This amplifies our defensi capabilities exponentially. Very quickly, employees go from being “Attack Surfaces” to being “Defence Forces”. 

How do we build this scalable defence force?

I have seen fast and fantastic results with the following: 

  1. Show, Don’t Just Tell: Teach employees what deepfake fraud looks like by showing them real-world examples. Explain the attacker’s psychology, just as the attacker understands the victim’s. Use internal case studies (if you have them) to illustrate the real-world impact. c. Provide focused training for high-risk teams like finance, HR, and senior executive tailoring the content to the specific threats they fac 
  2. Simulate, Don’t Just Lecture: Theoretical training is useless if employees cannot identify a real attack. Run realistic deepfake vulnerability assessments that mirror real-world scenarios. Use cloned voice calls, impersonated executive videos, and AI-generated emails that bypass security gateways. 

If criminals are impersonating your executives, why aren’t you simulating those scams to train your employees? 

  1. Shift the Mindset: Deepfake fraud is not just a CISO problem; it’s a business risk. Foster a culture where employees feel empowered to question unusual requests, even from senior leaders. Encourage a “pause and verify” mentality, especially when money or sensitive data is involved. Move away from the “act fast” culture that often leaves us vulnerable. 
  2. Make fraud harder: Implement secondary verification steps for urgent, sensitive, or financial reque b. Reassess your executives’ online presence and ensure they’re not inadvertently making social engineering easier. Are they oversharing travel plans or personal details? 

 

Thinking differently about security

Yes, we need to invest in defensive technology and robust processes. But we also need to invest in our people. We need employees who: 

  • Understand the why behind the security protocols. 
  • Feel psychologically safe to question authority. 
  • Are empowered to act, not just escalate. 

Cybercriminals are using AI to scale their attacks. We need to be just as strategic in scaling our defences. This means testing our employees before the criminals do. The best security investment is not always another tool. It’s a workforce that knows when they’re being played. Because in a world

where AI can fake faces, voices, and messages, a curious, cautious, and well-trained employee is the most valuable line of defence we have.
