Smart offices with IoT devices make work more efficient, but at the same time open new doors for cybercriminals. From smart lighting to access control systems: every connected device forms a potential entry point to company networks and sensitive data. With average data breach costs in the Benelux running up to 6 million euros, companies cannot afford to treat cybersecurity as a side issue when choosing office space.

New risks in modern office environments

The modern office has changed into an ecosystem of connected equipment. Lighting adjusts automatically, sensors measure occupancy and meeting systems run entirely in the cloud. These smart systems continuously collect data about presence, movement patterns and meeting activity. For companies, this means that facilities are no longer just about the pantry and meeting rooms, but also about the digital infrastructure and security behind them.

IoT devices are often designed with ease of use in mind, not security. Many devices ship with default passwords and limited update options. Even seemingly innocent components such as smart lightbulbs can be exploited to penetrate the company network. IP cameras, printers and wireless access points are among the most vulnerable links in office environments.

Hybrid working adds an extra layer of complexity. Employees switch between office, home and flex locations, each of which has its own security profile. Home networks often run on default settings, and public wifi on trains or in cafés carries risks such as eavesdropping and session hijacking. Neither way of working is automatically safer; actual safety depends on the measures that have been taken.

Office types and their security implications

A dedicated office or floor offers maximum control over the IT environment. Organizations can set up their own network cabling, firewalls and access control according to their own security standards. However, this autonomy also means full responsibility. Configuration errors or negligence are entirely the responsibility of the tenant, including all obligations under the GDPR and possibly the Cyber Security Act.

Serviced offices take a lot of digital provisions off your hands. This is attractive for SMEs: no investments in complex network equipment and benefiting from professional management. Because multiple companies share the same infrastructure, strict separation between networks is crucial. An incident at one tenant can pose a risk to others without good isolation. Access system logs and camera footage are managed centrally, meaning tenants must rely heavily on clear agreements about data processing.

From a cybersecurity perspective, coworking spaces are among the most challenging office concepts. The high dynamics, shared wifi and limited control over who sits where increase the chance of incidents, such as unauthorized network access or device theft. Companies that process privacy-sensitive data must therefore carefully determine which activities they carry out in a coworking environment and take additional measures, such as using a VPN and privacy screens.

Concrete security measures for smart offices

Network segmentation forms the basis of a secure office environment. By splitting the company network into zones with limited mutual traffic, a breach stays contained to one segment. IoT devices belong on a separate network, isolated from critical business applications. Guest users get access to a separate guest network without connection to internal systems. In a zero-trust approach, every access request is considered potentially untrustworthy, regardless of location.

Effective IoT security starts with insight. Organizations must maintain an up-to-date inventory of all connected devices, including building systems and own equipment. Default settings must be adjusted: change factory passwords, disable unused functions and set strong encryption. Regular firmware updates are essential to fix known vulnerabilities.

  • Implement strict network segmentation between IoT devices, guest networks and business-critical systems
  • Change all default passwords and disable unnecessary functions on IoT devices
  • Maintain an up-to-date inventory of all connected devices and their vulnerabilities
  • Install updates and patches consistently according to a fixed schedule
  • Actively monitor network traffic for abnormal behavior or unauthorized access attempts

The human factor remains crucial. Successful attacks often exploit weak passwords, phishing links or deception. A positive security culture, in which employees dare to report mistakes, is more important than a culture of blame and shame. Training should focus on practical skills: locking computers, securely destroying documents and recognizing suspicious people in open office spaces.

The GDPR defines personal data broadly. In smart offices, this includes access badge logs, camera footage, wifi login data and sensor data if these are traceable to individuals. The complexity increases because a lot of data is technically managed by landlords or external suppliers, while the tenant remains co-responsible for lawfulness and security. This requires clear data processing agreements and transparent arrangements about roles, access, retention periods and incident reporting.

The Cyber Security Act, the Dutch implementation of NIS2, introduces new obligations for essential and important organizations. Although the law is not yet in force, organizations must prepare for a registration requirement, an incident reporting obligation and a duty of care for appropriate measures. For companies falling under NIS2, office IT must also be included in risk analyses, especially when outages could disrupt service delivery.

The Digital Trust Center formulates five basic principles: take stock of vulnerabilities, choose secure settings, perform updates, restrict access and prevent malware. These principles align with the measures described earlier and form a practical starting point for organizations without an extensive security department.

The business case for office security

With data breach costs averaging 6 million euros in the Benelux, investments in preventive measures pale in comparison to the potential damage. Yet security investments are often postponed because the return is not immediately visible. For SMEs, realistic cybersecurity costs are usually between 50 and 300 euros per employee per month, with initial investments of several thousand to tens of thousands of euros, depending on the size and complexity of the organization.

The business case for office security is about limiting risks and preventing damage. An investment in network segmentation can prevent a compromised IoT device from leading to millions in losses. In addition, there are less tangible benefits: more customer trust, better compliance with laws and regulations, and a stronger position in sectors where security certificates are required.

Cyber insurance offers a financial safety net, but does not replace preventive measures. Insurers are setting increasingly strict requirements for security, such as timely updates, multi-factor authentication and network segmentation. Reputation damage and disruption of business operations are also difficult to insure, which is why prevention must be central.

Practical approach when choosing office space

When selecting office space, it is important to ask concrete questions about the digital infrastructure. Ask about the network setup, separation between tenants, the update policy for building systems, monitoring and the approach to incidents. Also ask what personal data is collected, how long it is retained, who has access and how it is secured.

Security should be seen as a fixed part of the quality of an office, not as an extra. An office with good network isolation, a careful update policy and transparent data processing can justify a higher rental price through lower risks of incidents. Be critical: a label such as "smart office" does not guarantee good security. Some environments with many smart applications are designed for convenience, while security receives little attention.

For organizations choosing a smart office environment today, it is essential not to see security as a brake on innovation, but as a condition for sustainable growth, continuity and trust.

Many companies find it difficult to include security in office decisions. The subject is quickly seen as too technical, or people fear that it complicates negotiations. A step-by-step approach helps: map out the biggest risks and address them in a targeted way. Bring in external experts where necessary for an objective assessment and concrete points for improvement.

The transition to smart offices offers opportunities for efficiency and flexibility. By including cybersecurity from the start in decision-making, organizations can benefit from these advantages without underestimating the risks. The difference between a smart and secure work environment and a costly pitfall lies in well-considered choices, thoughtful measures and a mature security culture. At a time when a single data breach can cost millions, investing in office security is not a luxury, but a necessity.
