"Cybersecurity now sits at the heart of how successful digital products are built, delivered and consumed. The failures in this space are hard to forget and even harder for digital businesses to recover from. In late 2025, Coupang, South Korea's leading e-commerce and fintech platform, disclosed a major data breach. Reportedly, a former employee was able to keep using an old internal key, gaining unauthorized access that went undetected for months."
"It was that failure in access control, key management and threat detection that contributed to missed revenue expectations and a decline in active customers. The shares fell sharply when the incident became public, and the discussion of potential penalties for this breach is still ongoing. Critically, failure in cybersecurity delivery doesn't only come from gaps in protection. It can also result from controls that are too rigid or poorly calibrated to real-world conditions."
"Overly aggressive security mechanisms can disrupt the very services they are meant to protect, turning defense into a source of failure. Around the same time as the Coupang incident, Cloudflare experienced an event that triggered a widespread outage affecting platforms such as X and ChatGPT. The root cause was not an external attack, but an internal configuration issue: a file used to manage threat traffic grew unexpectedly large and ultimately overwhelmed the system responsible for handling it."
"The result was downtime, disruption and loss of trust, which was caused by the security layer itself. Both incidents point to the same important conclusion: cybersecurity can no longer be treated as something separate from product delive"
Cybersecurity is among the fastest-growing skills through 2030, reflecting a shift from basic threat prevention toward defending against hacks, fraud, and DDoS attacks shaped by geopolitical risk. Cybersecurity failures directly affect how digital products are built, delivered, and consumed, and recovery can be difficult for digital businesses. A Coupang data breach involved a former employee using an old internal key to gain unauthorized access that went undetected for months, contributing to missed revenue expectations and fewer active customers. Cloudflare later experienced an outage caused by an internal configuration issue where a threat-management file grew too large and overwhelmed the handling system. These cases show that cybersecurity failures can stem from both weak protection and overly rigid controls that disrupt services, so cybersecurity cannot be treated as separate from product delivery.
