Miami and New York Hub Airports Top US Airport Website Security Rankings

128

A new study has found that Miami International Airport and the three large-hub airports serving the New York metro area rank among the most secure airport websites in the US.

The research, conducted by anti-detect browser company Gologin, assessed website security across America’s 30 large-hub airports by grading each site’s HTTP header security and Secure Sockets Layer (SSL) security. Each metric was graded from A+ to F, then converted into a score out of 100. The two scores were averaged to produce each airport’s overall security score.

8 airports tied for 1st place with scores of 97.5%

Seven of the eight airports, including Miami and the three New York area hubs, recorded an A+ in SSL security paired with an A in header security. Hartsfield–Jackson Atlanta International Airport was the only one of the eight to record the reverse combination, an A+ for header security and an A for SSL.

Fort Lauderdale–Hollywood International Airport placed 2nd with a score of 92.5, earning an A for header security and an A− for SSL security. Orlando International Airport, Dallas Fort Worth International Airport, and Charlotte Douglas International Airport tied for 3rd with scores of 90, each recording a B for header security and an A+ for SSL.

At the other end of the rankings, Daniel K. Inouye International Airport posted the lowest score of any large-hub airport, at just 50 out of 100. The airport received a B for SSL security but an F for header security, which pulled its overall score down sharply. Four airports tied for 2nd worst with scores of 57.5: San Diego International Airport, Austin–Bergstrom International Airport, Nashville International Airport, and Phoenix Sky Harbor International Airport, each of which received an F for header security alongside an A for SSL security.

Eugene Stepnov, Head of Marketing at Gologin, said: “Some of the country’s largest airports carry security vulnerabilities that other large-hub airports have already fixed.” He noted that it is concerning that five large-hub airports recorded F grades for header security, since this makes their websites more susceptible to attacks that insert malicious code into a site’s structure, allowing what look like harmless page elements to redirect users elsewhere or quietly transmit their information to hackers. He added that because airport websites handle sensitive traveller data, strong digital security matters even more at present, particularly with a major tournament like the World Cup underway.

Stepnov said: “Many of the lower-scoring airports could improve significantly through simple fixes such as updating their security headers, a straightforward change that would help guard against clickjacking and malicious redirects.” He advised travellers to protect themselves by using up-to-date web browsers when accessing airport websites and by blocking scripts from running when they are unsure what those scripts do, which he said would reduce the risks posed by sites that are more exposed to these kinds of attacks.

The findings add to broader concerns about airport website security. While not directly tied to mental health impacts, strong digital protections help support traveller confidence amid growing anxiety over data privacy in online travel bookings, with the research pointing to a link between website security standards and user trust at major transport hubs.
