Anti-Phishing and Web Surfing Security Tools Deployed Across More Than 200 Countries

London, June 6, 2018 – The Global Cyber Alliance (GCA) announced today several key milestones in its continuing mission to eradicate cyber risk through concrete actions.

The successful Quad9 DNS security service, which protects users from accessing known malicious websites, has grown more than 35-fold since its launch in November 2017, now reaching more than 120 countries and blocking up to 360 million connections to malicious and compromised websites in the past six months.

In addition, more than 22,000 organizations in 166 countries have used the GCA Domain-based Message Authentication, Reporting & Conformance (DMARC) Setup Guide to check their email domain’s phishing security and spoofing security. Nearly 5,000 organizations have deployed DMARC to protect their employees, partners and customers from being tricked by scammers trying to hijack their web domain to steal personal or financial information.

The announcements came following a meeting of GCA’s Strategic Advisory Committee, which comprises executives from more than 40 organizations spanning the finance, health, telecommunications, education, insurance, cybersecurity, technology, and media sectors, as well as government and law enforcement officials from Canada, France, the United Kingdom, and the United States.

“GCA was formed to take collective action to reduce and eradicate cyber risks, and we do this by uniting global communities, implementing concrete solutions, and measuring the effects,” said GCA president and CEO, Phil Reitinger. “We are passionate about helping users access affordable and automatic security solutions, and our progress over the past six months, in collaboration with many dedicated individuals and organizations, inspires us to keep moving forward and tackling new challenges.”

6 months of Quad9

The Quad9 DNS security service, which GCA conceptualized and built with IBM and Packet Clearing House, has scaled quickly since its launch six months ago. The service incorporates multiple threat intelligence feeds and blocks up to two million domain lookups each day, preventing users from connecting to a malicious website. More than a dozen cities were recently added to the service’s network of servers, including Bangkok, Thailand; Vilnius, Lithuania; Columbo, Sri Lanka; Siegerland, Germany; Posadas, Argentina; Luanda, Angola; Kiev, Ukraine; Kuala Lumpur, Malaysia; Enfidha, Tunisia; Harare, Zimbabwe; Lyon, France; and Tallinn, Estonia.

“We selected these regions because our deployment model is specifically designed to push our DNS services out to the very edges of the world in places where most other systems will not or cannot deliver excellent service,” said John Todd, Quad9 executive director. “Everyone should be able to enjoy a base level of security, privacy, and performance on the Internet regardless of location or economic circumstances. The focus as we grow our network footprint is to be in every country and every city in which we can deploy our service, regardless of economic weight, population density, or pre-existing network infrastructure.”

DMARC and Email Security

DMARC (Domain-based Message Authentication, Reporting & Compliance) was developed as a collaborative effort to combat fraudulent email by authenticating the sender of an email. GCA created a Setup Guide that enables world-wide adoption of DMARC, an email authentication standard that helps users protect their email domains from spoofers, spammers and phishing attacks.

The guide has been translated into 17 languages and has been used by more than 13,500 organizations in the past six months. In 2016, the U.K. government mandated that all U.K. government domains enable DMARC. The U.S. government followed suit in late 2017 with the issuance of Binding Operational Directive 18-01, requiring all U.S. federal civilian domains to enable DMARC.

New York, NY, March 29, 2018 – Mayor De Blasio launched NYC Secure, a cybersecurity initiative to protect New Yorkers from malicious cyber activity including when they access the NYC public WiFi. Part of the NYC Secure effort is the adoption of the Quad9 cybersecurity platform across all New York City guest and public WiFi access locations. Quad9 provides an automated security solution by leveraging the domain name system, known as the DNS, to block known malicious and bad websites through the use of more than 18 threat intelligence feeds. Not only does Quad9 provide a robust layer of security, it is highly privacy-preserving as no personally identifiable information is collected or stored. Quad9 is a free, easy to use service available to any organization, corporation, or individual.

By using Quad9 the city is also leveraging an investment made by NYC. Quad9 was created, in part, by the Global Cyber Alliance (GCA), a non-profit that was founded by Manhattan District Attorney Cy Vance, Jr., the City of London Police, and the Center for Internet Security, with a seed investment of asset forfeiture funds provided by the Manhattan District Attorney.

“This is a tremendous step in protecting citizens against all manner of cyber risk,” said Mary Kavaney, Chief Operating Officer of the Global Cyber Alliance (GCA). “The city in delivering free WiFi as a public service is taking a significant step to ensure that the service is provided with security built in while at the same time protecting New Yorkers’ privacy. While it’s impossible to protect against every threat, using Quad9 to protect against known malicious sites is a huge benefit to users of the service. On behalf of GCA, we commend New York City for taking this step.”

“Quad9 was built with the public in mind. It is a free service that provides security and protects the privacy of its users,” said John Todd, Executive Director of Quad9. “We’re very encouraged to see New York City embracing Quad9 and using it for public good, and we hope New York’s leadership in implementing this free service is a model for other cities to use to protect their citizens and networks.”

“NYC Secure delivers a world-class cybersecurity upgrade to New Yorkers and all who use our City’s expanding public WiFi network,” said Manhattan District Attorney Cyrus R. Vance, Jr. “In 2015, I joined with the City of London Police and Center for Internet Security to found the non-profit Global Cyber Alliance (GCA), which co-developed the Quad9 technology being adopted today. We are delighted to see the work of GCA and its partners integrated into groundbreaking programs like NYC Secure, which will expand the reach of safe-browsing technology and protect millions of residents and visitors alike. I commend Mayor de Blasio and his administration for its proactive and collaborative approach to combat the rising tide of cybercrime.”

“I applaud Mayor De Blasio for including Quad9 in his NYC Secure initiative which establishes New York City as a leader in helping to protect its citizens from malicious websites,” said John Gilligan, Executive Chairman, Center for Internet Security.

“The strength of the Global Cyber Alliance and the tools it has developed, such as Quad9, lie in the global partnerships that support it.  By harnessing talent and commitment from the within industry and the public sector, we take a step closer to tackling cyber crime,” said Ian Dyson, Commissioner, City of London Police.

Quad9 was conceived of by GCA and built in collaboration with IBM and Packet Clearing House (PCH). Since its launch in November of 2017, Quad9 usage has increased more than 27-fold and is used in more than 150 countries around the world, resolving billions of queries every day. Each day, approximately 2 million domain lookups are blocked, protecting the end user from connecting to a malicious destination. These blocked lookups represent attempts to reach phishing, ransomware, botnet command and control servers, and other forms of harmful or fraudulent systems.
