Case Study: Otto Group achieves 100% uptime and blocks DNS attacks with Akamai Technologies' Fast DNS Security Solution

The Otto Group protects its DNS servers and thousands of euros in revenues each minute with Akamai's DNS Security Solution

Otto Group, a global retail leader and the world’s second-largest online retailer with eCommerce accounting for about 60% of its revenue, faced a 2013 flood of malicious DNS requests that overwhelmed its domain name servers. Despite some mitigation by its IPS, DNS resolution hiccups left shoppers unable to reach major revenue-generating sites, risking significant losses and prompting the need for a fast, long-term cloud security solution.

Otto deployed Akamai’s Fast DNS solution after a two-day test and had protection in place within hours; Akamai’s global infrastructure blocked the attacks, restored full availability (up from 70–80% during the incidents) and improved DNS response times. The service ensured continuous site access, protected thousands of euros in revenue per minute, and freed Otto’s internal security team to focus on strategic projects.
