Cyber threats rise as flexible offices gain traction

More than two-fifths (43%) of UK businesses – around 612,000 companies – experienced a cybersecurity breach or attack in the past year, according to new analysis by office infrastructure specialists Co-space. The research highlights that information, technology, and professional service sectors are most at risk as flexible and shared office spaces grow in popularity.

The findings come amid a wider warning to UK computer users, with Microsoft ending support for Windows 10 last week – a move that could leave around 21 million Britons and 400 million users globally exposed to cyber threats.

Co-space analysed government data to identify which sectors faced the highest risks and how shared workspaces could be better protected.

“Workplace scams have become more sophisticated, and shared workspaces can unintentionally provide an attractive entry point if businesses are not properly protected,” said William Stokes, CEO of Co-space. “Whether through free Wi-Fi, communal devices, or the diversity of tenants, open environments demand a greater focus on cyber hygiene. Awareness and prevention are key.”

The information and communications sector was the most targeted, with 69% of businesses reporting attacks, followed by professional, scientific and technical services (55%), and finance, insurance, utilities and real estate (48%). By comparison, hospitality, retail, and food sectors faced fewer incidents but remain vulnerable to payment and data scams.

As co-working models expand across administrative, real estate, and service industries, workspace providers are responding with enterprise-grade security, including managed Wi-Fi, access controls, and real-time monitoring – features often beyond the reach of smaller firms.

Phishing remains the UK’s most common form of cyberattack, though reports have dipped slightly from 42% in 2024 to 37% in 2025. Other leading threats include ransomware, spyware, and identity theft, affecting businesses across remote, hybrid, and traditional work environments.
