ProtonMail offers state-of-the-art DDoS protection for your personal or business email. Our team has strong expertise in DDoS protection, having previously successfully mitigated one of the largest DDoS attacks to hit Europe. To provide comprehensive DDoS protection, we have partnered with Neustar. ProtonMail’s DDoS protection is not theoretical, since being implemented, it has withstood attacks exceeding 50 Gbps with no downtime.
As a result ProtonMail can offer uptime and stability which can even exceed that of the world’s largest email providers. We do this while simultaneously providing the highest levels of privacy and security. ProtonMail is one of the only email providers which owns and manages all of our servers and network components such as routers and switches. We are our own internet service provider and are a member of RIPE (Réseaux IP Européens). In addition to that, we also own and control a dedicated line linking our datacenter to the main Swiss Internet point of presence in Zurich so service interruptions on shared lines don’t impact us.
By hosting your business or personal email at ProtonMail, you can ensure that you are protected against DDoS attacks. If your business or website ever comes under DDoS attack (or if another business hosted at the same location as you comes under attack), with ProtonMail you can ensure that email, your most important way of communicating with customers, will stay online and available.
