ThousandEyes, the company that empowers businesses with Network Intelligence, has found that 50% of the financial firms listed on the Financial Times Stock Exchange (FTSE) 100 companies are not adequately prepared for the next major attack on the domain name system (DNS), according to the results of the 2018 ThousandEyes Global DNS Performance Report.

Key findings of the 2018 ThousandEyes DNS Infrastructure Performance Report include:

  • Overall, 72% of the FTSE 100 companies are not prepared for a major attack on the DNS
  • The report found similar vulnerability among 68% of the top 50 companies on the Fortune 500 rankings and 44% of the top 25 SaaS providers
  • Leading financial organisations remain needlessly vulnerable: DNS best practices are not widespread, exposing them to severe risk and potentially making them vulnerable to the next attack such as Dyn experienced nearly two years ago

Cloudflare, Google and OpenDNS are Top Public DNS Performers

In addition, the report also measured public DNS providers. Out of fifteen of these providers, it found that newcomer Cloudflare had the overall fastest performance, followed by Google and OpenDNS, both of which improved over their performance in the 2017 ThousandEyes analysis. Top providers varied by region and country. Performance highlights of the 2018 report include:

  • In the United States, Google was the top performer, followed by Cloudflare and OpenDNS.
  • In the UK, Level 3 had the best performance, followed by Google and OpenDNS.
  • In Japan, Cloudflare was the fastest performer, with Google in second and Neustar in third place.

“Without DNS, there is no Internet. It’s how users find a bank or financial company’s apps, sites and services on the Internet. A DNS performance issue or attack can have a critical impact on customer experience, revenue, and a financial organisation’s reputation,” said Angelique Medina, senior product marketing manager at ThousandEyes. “The ThousandEyes report highlights vital insights that can help banks and financial companies design a more effective DNS infrastructure — because even the most basic DNS decisions can determine how their application or service, and ultimately how their overall brand, is perceived.”

Report Scope and Methodology Fifteen public DNS providers were extensively measured and ranked for the report, including CleanBrowsing, Google, OpenDNS Quad9, and Verisign. Managed DNS Providers and DNS Root servers were also measured. ThousandEyes collected data over the course of 30 days—between August 19 and September 19, 2018—which resulted in more than 15M data points. The state of DNS resilience amongst major enterprises and SaaS providers was also collected.
