About Us

ThreatSTOP is About Taking Action

ThreatSTOP’s founder, Tom Byrnes, created the company in 2009 with a distinct mission and vision…why can’t smaller companies get the same cybersecurity solutions that Fortune 1000 companies can have? Was there a way to deliver security to customers that automated tedious processes and augmented the capabilities of companies with limited IT and Security staffing and resources?

A Threat Intelligence Platform That Delivers

ThreatSTOP evolved into what is it today, a cloud-based automated threat intelligence platform that converts the latest threat data into enforcement policies, and automatically updates your firewalls, routers, DNS servers and endpoints to stop attacks before they become breaches.

Powerful Threat Intelligence DNA

ThreatSTOP leverages the company’s comprehensive and authoritative database of IP addresses, domains and the network infrastructure used in cyberattacks to develop best-in-class threat intelligence. Our world-class security team curates the latest threat information from more than 50 public and proprietary sources including trust groups and law enforcement, and dynamically updates your policy as the threat landscape changes.

What we do

ThreatSTOP was started in 2009 with a mission: Give organizations of any size the same cybersecurity protection that Fortune 1000 companies have.

Few companies have the resources to curate threat intelligence feeds into machine readable enforcement policies. Fewer still have the resources to update their network devices with those policies.

ThreatSTOP addresses protection gaps for both inbound and outbound network traffic with cloud-based automated threat intelligence and Protective DNS, converting the latest threat data into enforcement policies, updating devices to stop attacks before they become breaches.

The team has more than 120 years’ combined experience in security research.

Tomás Byrnes

Founder & CEO

Tom Byrnes is a long-standing member of the global cybersecurity community, serving in the U.S. Army for 13 years and ultimately joining the seminal tactical networking group.  In the private sector Toms work started with designing large-scale global networks, and providing technical advice and leadership for a number of successful startups that all resulted in successful acquisitions. Tom holds four patents in network security using DNS, and is credited as the inventor on two additional patent applications. An active member of the IEEE, ISSA and Infragard, Byrnes speaks regularly at conferences on the topic of security.

Ever the adventurer, Tom dives, surfs and hikes around ThreatSTOP's HQ in beautiful North County San Diego, and takes advantage of down time on business travel to learn about the local culture and make friends, which he is blessed with all over the world.

Paul Mockapetris

Chief Scientist

Mockapetris is the inventor of the Domain Name System (DNS). His mission is to help guide DNS and IP addressing to the next stage. His earliest work at UC Irvine on distributed systems and LAN technology preceded the commercial Ethernet and Token Ring designs. At ISI, after working on the design and initial implementation of the SMTP protocol for email as part of the birth of the Internet in 1983, he took on the challenge of designing DNS, and then operated the original “root servers” for all Internet names.

When not inventing new ways for the internet to communicate, Paul enjoys tennis and wine, sometimes both together.
