DDoS attacks on S3-hosted sites lead to unexpected costs

Severity: SevereOpportunity: 4/5SecuritySaaS

The Problem

Many users hosting static websites on S3 are concerned about the risk of DDoS attacks that could result in exorbitant billing. Unlike traditional hosting services, S3 lacks robust built-in protections against such attacks, leaving users vulnerable when they cannot monitor their accounts actively. This fear of financial loss is compounded by the unpredictability of attack timing, especially during off-hours or vacations.

Market Context

This pain point aligns with the growing trend of cloud security concerns as more businesses migrate to cloud services like AWS. With the increasing sophistication of cyber threats, users are seeking better protective measures for their cloud-hosted assets, making this a timely issue.
