Hotel cybersecurity: protecting guests beyond the room door

By Ander Pérez Achústegui – Echate, Business Development Manager, FAGOR Multimedia Perspectives

For decades, hotel security has mainly been associated with physical elements: a sturdy door, a reliable lock, a safe, security cameras or staff trained to handle any incident. These elements remain essential, because they are part of the basic trust a guest places in the establishment when choosing to stay there. Today, however, guest security no longer ends in the physical world. In an increasingly digital environment, cybersecurity has become an essential part of the hotel experience.

This concern is not theoretical. According to recent industry data, tourism companies suffer more than 2,200 cyberattacks a week, and this figure has doubled in just three years. As hotels, campsites and other establishments add new digital services to improve the customer experience, the need to protect those environments from potential threats grows too. At the recent ITH Innovation Summit, the need to protect the digital environments used by guests also came up repeatedly in conversations between industry professionals.

When guests arrive at a hotel, they find themselves in an unfamiliar environment. They do not know which WiFi networks are legitimate, which QR codes really belong to the establishment or what happens to their data when they use digital services from their room. Nor do they always know the hotel's official channels for checking information, accessing services, making a booking, asking for help or connecting to the internet. That lack of context makes them particularly vulnerable to digital scams, impersonation or unauthorised access to personal information.

In addition, guests often have no clear tools to detect fraud, report it or ask for help straight away. They may scan a fake QR code, connect to a fraudulent WiFi network or leave a personal session open on a multimedia platform without realising the risk until hours or even days later. This creates a situation of exposure in which the hotel plays a key role: reducing digital vulnerabilities within its own establishment as far as possible and offering a clear, controlled and secure environment.

Although cybersecurity is often associated with complex attacks on IT systems, a significant share of the risks arises from everyday elements that guests interact with every day.

QR codes, an invisible threat in trusted spaces

One of the most visible examples is the widespread use of QR codes. Today we find QR stickers on restaurant tables, walls, rooms, lifts, reception desks and common areas. They are convenient, fast and useful, especially for accessing menus, tourist information, hotel services, promotions or digital menus. But that same ease of use can become a threat if they are not properly managed. A simple sticker can be replaced with a fake one without staff or guests noticing straight away.

The guest believes they are accessing the hotel's official website, the restaurant menu or an internal service, but may in fact be going through a fraudulent gateway designed to capture their personal data, credentials or banking information. In some cases, the attack may be designed so that, after capturing the data, the user is redirected to the hotel's real website. From the guest's point of view, everything seems to have worked normally, which makes the fraud even harder to spot.

This threat is particularly delicate because it relies on a gesture that has become completely normal. Guests scan a QR code because the environment itself has taught them that this is the usual way to access many services. They do not suspect a sticker placed on a table, a wall or next to reception, because they assume it belongs to the establishment. That is why, when a hotel relies solely on physical QR codes without central control, it leaves open an attack route that is simple, cheap and hard to monitor constantly.

WiFi and connectivity, the other gateway

Something similar happens with WiFi connectivity. A hotel has multiple networks side by side: internal networks, guest networks, service networks, external devices or nearby access points. In some cases, networks from other establishments, nearby shops or private devices may even appear. It is not always obvious to the guest which network is the right one. An attacker can take advantage of that confusion by creating a network with an apparently legitimate name, tricking the guest into connecting to a fake WiFi.

On top of this, the use of open or poorly identified networks can allow third parties to carry out illicit activities under the umbrella of an infrastructure that neither the guest nor the hotel properly controls. Internet access can no longer be seen simply as an extra service or a convenience for the guest. In a modern hotel, connectivity is part of the critical infrastructure of the guest experience and must therefore be managed with criteria of security, identification and traceability.

Multimedia platforms and guest privacy

The third threat relates to the use of multimedia platforms in the room. Guests expect to access services such as Netflix, HBO, Prime Video or other entertainment platforms as easily as at home. This demand is increasingly common, especially in hotels seeking to offer a personalised, modern, high-end experience. However, if the technology ecosystem is not well designed, a feature intended to add convenience can become a privacy risk.

When a guest enters their credentials on a TV, in an app or in a system that is not properly isolated, their data may be exposed. The session may also remain active after check-out, or the next occupant of the room may be able to access profiles, viewing history, recommendations or even change account details. The problem is not offering digital entertainment, but doing so without the necessary safeguards to keep guest information protected before, during and after their stay.

The conclusion is clear: guests are an easy target when the hotel's digital infrastructure is not protected, controlled and designed with security in mind. Not because guests act carelessly, but because they are moving through an unfamiliar environment that they trust. That trust is one of the hotel sector's main assets, and it must also be protected in the digital sphere.

How to reduce risks without complicating the experience

The good news is that there are now technology solutions that can reduce these risks very significantly. The first step is to replace vulnerable elements, such as physical QR stickers, with digital access points integrated into secure IT systems. A QR code embedded in a screen, in the hotel's information system or in a centrally managed platform cannot be physically replaced by a third party. It also allows remote updates, control over the content displayed and much more agile management by the establishment.

This type of solution offers a double advantage. On the one hand, it improves security, as it eliminates the possibility of physical tampering with the QR code. On the other, it improves hotel operations, because menus, opening hours, promotions, services or relevant information can be updated without depending on new prints, manual replacements or constant checks of stickers spread throughout the building. In this case, security also means efficiency and control.

For WiFi, good practice is to display the access details directly on the room TV or on an official hotel interface. This way, guests can clearly identify the correct network and avoid falling for fake or spoofed networks. If access is also through a captive portal, the establishment can guarantee a more controlled, secure and traceable connection, where users are properly identified and network use is better managed.

There are also Cast platforms designed specifically for hotel environments. These solutions let guests enjoy their personal content on the room TV without unnecessarily exposing their credentials. To do so, the system must work with isolation by room or zone, with minimal user information and with automatic deletion of data at the end of the stay. The aim is to offer convenience without compromising privacy.

This point is especially important because personalising the hotel experience should not be at odds with data protection. Guests want to feel at home, connect easily and access their content without friction. But they also expect their information to disappear with them when they leave the room. A good technology ecosystem must guarantee exactly that: ease of use during the stay and secure deletion of any data linked to the guest once it ends.

Hotel cybersecurity should not be seen as an invisible technical layer, but as one more part of the guest experience. Just as a room has a door to protect the belongings a guest leaves inside, the hotel must also protect the digital environment in which that guest moves during their stay. Security is no longer just in the lock, but also in the network, the screens, the digital access points, the QR codes and the platforms the guest uses.

In a context where the tourism sector has become one of the usual targets of cybercrime, protecting digital environments is no longer purely a technological issue, but a fundamental part of the trust the establishment conveys to its customers.

Reducing cyber vulnerabilities within the establishment is no longer an option but a responsibility. The hotel must ensure that its digital services are secure, clear and reliable. Guests, for their part, should be able to focus on what matters: enjoying their stay, their holiday or their business trip with peace of mind.

Because protecting guests today means protecting both their luggage and their data.
