Risks of inadequate cloud infrastructure security.
Inadequate cloud infrastructure can pose various brand risks, including cyber-attacks, data breaches, reputation damage, and legal and financial liabilities. Consider the following statistics:
Cyber attacks and data breaches:
- According to a 2021 report by IBM, the average data breach cost is $4.24 million.
- The same report found that the average time to identify and contain a data breach is 287 days, which can significantly damage a brand’s reputation and customer trust.
- A 2020 report by McAfee revealed that the number of external attacks on cloud accounts increased by 630% from January to April of that year.
Reputation damage:
- According to a 2021 survey by Edelman, 90% of consumers said they would stop doing business with a brand if they learned it mishandled their data.
- In the same survey, 86% of respondents said they would recommend competitors over a brand that experienced a data breach.
Legal and financial liabilities:
- Under the EU’s General Data Protection Regulation (GDPR), fines for non-compliance with data protection regulations can reach up to €20 million or 4% of a company’s global annual revenue, whichever is greater.
- In 2019, due to its inadequate cloud security measures, The US Office of the Comptroller of the Currency fined Capital One $80 million
