Cybersecurity Risks from Legacy and Third-Party Hotel Systems

Legacy hotel systems, particularly property management systems (PMS), pose significant cybersecurity risks due to their outdated technology and lack of support. As hotels increasingly rely on interconnected systems, the exposure to third-party vulnerabilities has also risen, with 30% of breaches involving third parties according to Verizon's 2025 report. The National Institute of Standards and Technology (NIST) emphasizes the importance of securing PMS as it connects to various other systems, including payment platforms and access controls. The challenge for hotel operators lies in managing these risks while maintaining operational efficiency. Many hotels continue to use legacy systems due to the high costs and disruptions associated with upgrading. This interconnectedness can lead to severe impacts if a third-party vendor is compromised, affecting guest data and operational capabilities. The current status indicates that hotels must reassess their cybersecurity strategies to address these vulnerabilities effectively.

Key Points: • Legacy hotel systems are increasingly vulnerable due to outdated technology and lack of support. • 30% of data breaches involve third-party technology, highlighting significant cybersecurity risks. • Hotels must balance operational efficiency with the need to upgrade legacy systems to enhance security.
