Cybersecurity resilience depends on having the right technologies, processes and expertise in place to detect threats, reduce risk and respond quickly to incidents across complex environments. Chris Tayler, Head of Information and Cloud Services, ODEON Cinemas Group, tells us how the cinema operator used Microsoft Sentinel, Microsoft Defender XDR, BlueVoyant’ s Managed Detection and Response( MDR), Digital Forensics and Incident Response( DFIR) services and third-party risk management capabilities to unify security operations across eight countries, reduce alert volumes by 98 % and strengthen its overall cyber-resilience.

lueVoyant has partnered with ODEON

Cinemas Group( OCG), Europe’ s largest cinema operator, to unify and modernise its security operations across eight countries.

The collaboration delivers 24 / 7 protection, rapid incident response and enhanced visibility into third party risk, significantly reducing operational noise and strengthening OCG’ s overall cyber-resilience.

OCG welcomes millions of guests each year to more than 280 cinemas across Europe. As the cinema exhibition industry faces a growing wave of cyber-attacks, from disruptions to ticketing and concessions systems to breaches involving customer data, OCG requires an increasingly proactive and integrated approach to its cybersecurity.

With nearly 50 different log sources and a diverse technology landscape, OCG needed a partner capable of centralising operations, improving visibility and reducing the burden on regional InfoSec teams.

OCG’ s previous security provider operated largely as an alert forwarding service, offering limited proactive tuning and no on-going use case development. This left internal teams overwhelmed by unnecessary alerts and without the strategic support required to stay ahead of evolving threats.

To gain clarity on its security posture, OCG commissioned a BlueVoyant Security Diagnostic, which confirmed gaps in alert logic, configuration weaknesses in Microsoft Defender XDR and a legacy SIEM that were adding costs without delivering proportional value. The diagnostic provided the evidence and roadmap OCG needed to modernise its approach and consolidate services under a single trusted partner.

Following the diagnostic, BlueVoyant migrated OCG from its legacy SIEM to Microsoft Sentinel, enabling
