When we imagine hackers, the image is often the same: someone in a dark hoodie, lit only by the glow of a laptop screen. But according to security experts, cybercriminals increasingly exploit an overlooked vulnerability: physical access to corporate spaces.
Daniel Dilks, director of operations at Sentinel Intelligence, stated that if you’re wearing a uniform, people don’t really question you. While companies spend heavily on cybersecurity, few are fully prepared for threats that walk through the front door.

The Hidden Frontline of Cybersecurity
Global cybersecurity spending is projected to hit $213 billion (Rs. 18,65,415 Crores) in 2025, yet only 4% of organizations are fully prepared for modern threats, according to Cisco’s 2025 readiness index. Physical breaches can undermine even the strongest digital defences.
Sentinel Intelligence’s penetration tests have uncovered startling lapses:
- Tailgating into corporate headquarters — Operatives in business attire followed employees inside, planted rogue devices, and accessed guest networks without challenge.
- Out-of-hours lock picking — Testers entered via side doors, retrieving sensitive documents from unsecured filing cabinets.
- Social engineering — A fake contractor, dressed in high-visibility gear, was escorted into a server room, where they photographed exposed credentials and installed a USB “dropbox.”
Each method bypassed digital firewalls entirely, exposing systems from within.
Costs Beyond the Break-In
The World Security Report 2023 estimates that large corporations lost $1 trillion (€860bn) in 2022 due to physical security incidents. The damage ranges from immediate equipment sabotage to extended downtime, lost contracts, and reputational harm.
Some attacks are unconventional. In one U.S. case, hackers infiltrated a casino network through a smart aquarium’s water-regulating device. Elsewhere, researchers have demonstrated that smart kettles can be hacked to extract Wi-Fi credentials, which then open the door to broader network compromise. Experts stress that vigilance, not hostility, is key.
