Chairman, CEO and Cofounder
Dr. Paul Vixie is an internet pioneer. Currently, he is the Chairman, CEO and cofounder of award-winning Farsight Security, Inc. Dr. Vixie was inducted into the internet Hall of Fame in 2014 for work related to DNS and anti-spam technologies. He is the author of open source internet software including BIND 8, and of many internet standards documents concerning DNS and DNSSEC. In addition, he founded the first commercial anti-spam company (MAPS, 1996), the first non-profit internet infrastructure software company (ISC, 1994), and the first neutral and commercial internet exchange (PAIX, 1991). In 2018, he cofounded SIE Europe UG, a breakthrough European data sharing collective to fight cybercrime. Dr. Vixie earned his Ph.D. from Keio University for work related to DNS and DNSSEC in 2010.
Dr. Vixie is frequently invited to deliver keynotes at technology and business events around the world. He has presented at such events as Copenhagen Cybercrime Conference, FIRST, Palo Alto Networks IGNITE, RSA, Black Hat, DNS-OARC, SANS, Swiss Cyber Storm, and VirusBulletin.

Improving Internet Security Through Cooperation: The SIE Approach
In this article, Dr. Vixie provides his take on a recent study on web traffic, which showed that only a small percentage of the traffic is benign. "On the internet, nothing that can be abused will not be," he says.
In this interview, Dr. Vixie explains why public DNS servers run by Google and other vendors provide few benefits and are costing users both privacy and time. Here, he advocates organizations run their own local DNS servers.
In this piece, Dr. Vixie discusses the future of Whois and the possible success of advocacy groups working to pass legislation to enable security practitioners to have access to this data for years to come.
Explaining his decision to offer real-time and historical passive DNS solutions, Dr. Vixie said, “We decided to invest and make a long, multi-year strategic investment in trying to create a system that would put back pressure on the real source of trouble, which is that these things [domains] are too cheap.”
In this interview, Dr. Vixie explains why he cofounded Farsight Security. “All war is a matter of economics. It continues until one side lacks the resources to continue. That’s the approach we take to cyber security — to make what online criminals are trying to do both difficult and expensive for them.”
Dr. Vixie urges people to take control in shaping an internet that is safer and more true to the original community-based mission a couple of decades ago. “We must not let it just be the big tech companies that decide humanity’s future. There are enough people with good intentions out there.”
In this interview, Dr. Vixie discusses why he believes social media giants are engaged in "surveillance capitalism" and are "merely paying lip service" to combating the rise of disinformation, data misuse, and online abuse. “They are merely paying lip service to it, delaying and deceiving and misdirecting as a way to continue growing revenue and their share price.”
The DNS inventor talks about the past, present and future of security.
Looking back 30 years when The Morris Worm hit, Dr. Vixie reflects, "[The Morris Worm] was a seminal event. It was the first time we realized a global, connected infrastructure was going to be globally vulnerable."
In this interview, Dr. Vixie discusses why he cofounded SIE Europe: “We founded SIE Europe to build a European-based community of Internet defenders who want to make the Internet safer for all users.
Dr. Vixie explains how global Internationalized Domain Names, or global IDNs, sparked the emergence of confusingly similar website addresses with nefarious goals -- and how organizations can combat them.
An interview with Dr. Vixie about the Farsight research report, "The Modality of Mortality in Domain Names: “Yes, we're seeing more blacklisting today. And I saw this coming -- again, I'm a bit of cynic. In 2010 at my previous company, a nonprofit DNS research and operations company, we invented a language for DNS blacklisting (DNSBL).”
An interview with Dr. Vixie about the Farsight research report, "The Modality of Mortality in Domain Names." “Most of them die young, and most of them die after living short, brutal lives," he says of newly created domains.”
Dr. Vixie explains how IDN homographs are being used in phishing attacks against major airliners. “It is the perfect crime because once you have gathered someone’s real username and password, you can impersonate them on the airline’s website.”
Dr. Vixie discusses the uncertain fate of WHOIS in the age of GDPR, the risks of domain name homographs, and other underpinnings of the Internet that are hard to trust and harder to fix.
An interview with Dr. Vixie about his work on the Conficker Working Group and why Conficker is still around 10 years after its’ first discovery. "We got it from 11 million down to one million," said Dr Vixie. "That sounds like progress but one million is still a pretty big number."
In this piece Dr. Vixie discusses the increase sale of U.S. Senator domain names using the .forsale domain extension and possible risks to the U.S. midterm election. “It’s no different from dot-sucks,” said Paul Vixie, a highly regarded computer scientist who helped design the system of Internet addresses current in use. “Social commentary has always thrived on the Internet, due to reach and cost issues.”
In this interview, Dr. Vixie discusses the Farsight research report on IDNs and the security risks these homographs pose to organizations. "Any lower-case letter can be represented by as many as 40 different variations."
In this interview, Dr. Vixie explains why he doubts ICANN will remove .ru from the Internet. “That would be the biggest shockwave in the history of the Internet,” he says. “It would cause not just Russia but other countries to say, ‘We can’t trust ICANN.’”
In this interview, Dr. Vixie reflects on the early days of the Internet and his contributions to the Domain Name System (DNS). “You're always going to get something you weren't expecting as one of the results of a rebellion and I don't like seeing the DNS used for crime, that's true.”
Discussing why security was not top of mind when the Internet was first created, Dr. Vixie said, “No one ever thought someone would want to lie in the 'from' field of an email, or send email the recipient wouldn't want. And that made sense for a network of academics and military contractors, before anyone who could pay an internet service provider could get online.”
In this interview, Dr. Vixie discusses why the cybersecurity M&A market is hot right now: “The M&A market is extraordinarily frothy,” says Paul Vixie. “[This market] is like bitcoin. If you think everyone else is excited about it, you invest in it.”
Dr. Vixie shares Farsight research about the security risks posed by IDNs. “This problem got worse than we thought it could, faster than we thought it could,” said Paul Vixie, Chairman and CEO of Farsight Security and one of the developers of the Domain Name System that configures IP addresses into readable domain names.
