Berú A/S

Berú A/S, also known by its alias, is a hosting provider headquartered in Denmark. The organisation delivers hosting services to a range of clients, including governmental entities. It operates within the Danish information technology sector. Public sources refer to the company by both its legal name and the alias Berú A/S. Its core activity is the provision of hosting solutions to customers.

On 11 September 2023, Berú A/S experienced a distributed denial-of-service (DDoS) attack that targeted one of its governmental customers. The attack triggered critical alarms in the company's monitoring systems and prompted the activation of emergency response protocols. Traffic analysis showed that the malicious traffic originated predominantly from foreign internet service providers. In contrast, the provider's normal traffic pattern typically sees approximately ninety‑eight percent of packets sourced from domestic networks. The DDoS event occurred alongside concurrent hardware failures that exacerbated service disruptions.

The combined effect of the DDoS attack and hardware failures impacted multiple clients' services hosted by the provider. The incident highlighted vulnerabilities in the organisation's infrastructure under extreme load conditions. Following the event, discussions emerged regarding potential IP allocation strategies to isolate critical domestic traffic from foreign‑sourced attacks. The specific size of the company, such as employee count or annual revenue, is not disclosed in the available sources. Similarly, details concerning its ownership structure or any parent‑subsidiary relationships are not provided in the public information.
