The companies said they had been dealing with the incident since Sunday afternoon and had taken immediate measures to protect their IT environments. These included temporarily shutting down some systems as a precaution.
As a result, the websites, apps and customer service channels of Albert Heijn, Etos and Gall & Gall were temporarily unavailable. Albert Heijn's logistics systems were also affected, preventing the supermarket from delivering groceries ordered online until further notice.
Despite the incident, the companies' physical stores remain open. Albert Heijn said its checkout systems were functioning and the national Bonus offers advertised in the current week's flyer remained available.
However, electronic shelf labels were still displaying promotional prices from the previous week. This meant customers could see a lower price on the shelf than the amount charged at checkout for some expired promotions.
The incident has also affected Albert Heijn's loyalty and savings schemes. Services linked to the Mijn AH app and personal Bonus Card, including Mijn Bonus Box discounts, Koopzegels savings stamps and Air Miles, were temporarily unavailable.
The supermarket said customers who missed out on personal discounts because of the disruption would be compensated as soon as possible. Customers were advised to keep their receipts to help with the process.
Ahold Delhaize, the parent company of Albert Heijn, confirmed that it was experiencing a security issue within its network. The company said its teams were working to assess and mitigate the problem, including taking some systems offline to protect them.
Ahold Delhaize said its stores remained open and continued serving customers. It identified the protection of its infrastructure, customers, employees and business partners as a priority.
The companies have not yet provided a timeline for restoring the affected services. Albert Heijn said it was investigating the incident and would issue further updates when more information became available.
The disruption has created uncertainty for customers who rely on online grocery orders and digital loyalty benefits. The companies apologized for the inconvenience and said customer data protection remained a key priority.
