Football stadiums are becoming dense digital environments, not just sporting venues.
As the Premier League season begins, fans expect instant connectivity. They use phones for tickets, payments, messaging, clips, and social media. At the same time, stadium teams run surveillance, access control, retail, and operations over connected systems.
That growing dependence makes secure Wi-Fi a match-day priority.
The threat gaining attention is the “evil twin” attack. In this attack, criminals create a fake wireless network. It looks like the official stadium network. Fans may connect and then reach a fake login page. There, attackers can harvest credentials or personal details.
Markus Nispel, Head of AI Engineering and EMEA CTO at Extreme Networks, says the risk needs perspective.
“Every aggregation of people is a potential target,” Nispel tells Mobile Europe, but he warns that the amount of data that can be extracted today is “very limited”.
Modern apps now use stronger encryption by default. That makes simple traffic snooping less useful than before. However, fake portals remain dangerous. They can trick users into sharing information voluntarily.
Public wireless access has also changed significantly.
A decade ago, many venue portals asked for email addresses and phone numbers. Some also collected other personal details for marketing. That created more value for criminals building fake sign-in pages.
“Around a decade ago, every venue operator wanted your identity, your credentials for marketing purposes, asking for your personal details,” he says.
Today, many venues reduce these barriers. They want fans online quickly. Security matters, but convenience also drives the shift. If access takes too long, users choose cellular instead.
“The main driver for that was more of a frictionless onboarding experience,” he says.
This creates a better fan experience. It also reduces stolen data opportunities. Yet it does not remove the need for strong network monitoring.
Responsibility remains shared when something goes wrong. Fans should verify secure websites and valid certificates. They should avoid entering sensitive data into suspicious portals.
“As a user, you should always also use encrypted protocols for any of your activity, whether it’s connecting to websites; we should make sure that certificates are valid,” he notes.
Stadium owners must also play their part. They need tools that detect rogue access points. Wireless intrusion detection can spot suspicious networks near the venue. Prevention tools can also steer users back to trusted infrastructure.
Network segmentation adds another layer. It separates systems such as payments, ticketing, operations, and surveillance. If one area faces attack, others stay protected. This limits damage and supports safer shared infrastructure.
AI now supports threat detection across many networks. It can spot unusual wireless behavior faster than manual teams. Still, attackers can use similar tools.
“I would call it an arms race, like it is with traditional technologies,” he says.
For stadium operators, the lesson is clear. AI helps, but it cannot replace basics. Encryption, segmentation, authentication, and intrusion detection remain essential. Fans want seamless access, but venues must build trust into every connection.
