A real customer logs in with the right credentials and sends money. Every identity check can be satisfied. The money can still be going to a fraudster. For Alisdair Faulkner, this is where a familiar problem becomes interesting again: knowing who someone is leaves considerable room for misunderstanding what is happening to them.
Faulkner helped build ThreatMetrix, the digital identity business acquired by LexisNexis Risk Solutions in 2018 for a reported $830 million. He now leads Darwinium, another company occupied with trust online. The continuity is obvious. The change lies in the object of attention, from identifying a visitor to following a visitor’s behavior through a sequence of decisions.
It is an engineer’s problem with an unusually human center. A system can recognize the account holder perfectly while failing to recognize the predicament. The person at the keyboard may be acting freely, following instructions, or being deceived. The machine has accepted the password. The difficult part of the story has barely begun.
A company named after a place, with an argument attached
Darwinium begins, quite literally, in Darwin. Faulkner was born in the Australian city and credits his remote upbringing with encouraging his entrepreneurial spirit and interest in technology. The name also borrows from Charles Darwin. A company concerned with adapting to changing threats could have left the reference there and ordered the stationery.
Faulkner adds a twist. Darwinium has used the motto “Survival of the Unfittest,” expressing a wish to protect people least able to protect themselves. That phrase puts a social ambition inside the technical brief. An internet that rewards only the vigilant, experienced and suspicious would leave plenty of ordinary people outside its protections.

The phrase is also a useful test of the product argument. Better defenses should give legitimate people a clearer path through a service. If every visit becomes an examination, with the customer repeatedly summoned to prove innocence, the cost of security falls partly on the people it is supposed to help. His stated ambition includes keeping the digital world accessible.

The fingerprints before the footsteps
His route into that argument runs through engineering and product development. Faulkner holds a master’s degree from the University of Adelaide, focused on information technology and telecommunications. His earlier work included Accenture’s e-commerce practice and NetPriva, where he was a founder involved in products and business development. Network performance came before digital identity.
NetPriva was acquired by Expand Networks in 2008. ThreatMetrix, co-founded in 2005, became the larger public chapter. As chief product officer, Faulkner worked on a business that assembled signals from devices, locations and behavior to assess the risk of online activity. His patent listings reflect that interest in recognizing computers through combinations of identifying characteristics.
By January 2018, the network had substantial reach. When RELX announced its agreement to buy ThreatMetrix for £580 million, it described technology spanning 1.4 billion online identities and 4.5 billion devices across 185 countries. More than 100 million transactions a day passed through its analysis. These were the dimensions of the business, rather than a measure of any individual’s fortune.
The acquisition brought digital signals into a business already working with physical identity attributes. It also gave Faulkner a different vantage point: he went on to lead global fraud and identity markets and strategy at LexisNexis Risk Solutions. Building a product and taking responsibility across markets are related jobs, but they expose different parts of the same customer problem.
The space between a login and a payment
Darwinium’s premise begins with the parts of an interaction that separate tools can miss. A business may inspect account creation, login and payment using different systems. Each can perform its assigned task while the sequence connecting them remains poorly understood. The paperwork is in order at every desk. Nobody has read the whole file.
Faulkner’s proposed response is to connect those moments. Activity during browsing can inform a later decision at checkout. A change of account details can matter when a payment follows. The useful unit becomes the journey, allowing an earlier signal to retain its meaning when the customer reaches a different part of the service.
His explanation of scams makes the distinction concrete. Sometimes the customer initiates the payment and passes authentication because the customer is exactly who they claim to be. The deception concerns what the payment is for. Under those conditions, another successful identity check contributes less than an understanding of the behavior surrounding the decision.

There is an infrastructure choice behind this. Darwinium runs at the network perimeter through content delivery networks, including Cloudflare and AWS CloudFront. Its 2023 financing announcement described a deployment model intended to let businesses observe activity and change the response as interactions unfold, with third-party intelligence available to enrich decisions.
Faulkner has also argued that organizational divisions make the technical problem harder. Fraud and cybersecurity teams can hold different fragments of the customer’s activity. Connecting their view matters when attackers move across those boundaries. In his 2024 discussion of edge security, he stressed both visibility and the ability to respond quickly. A complete picture arriving too late has limited practical charm.
Old colleagues, another beginning
The new venture brought familiar experience into the room. Darwinium’s leadership includes Ben Davey, Caleb Moore and Colin Goldie, whose previous roles were at ThreatMetrix. Reed Taussig, formerly ThreatMetrix’s CEO, became Darwinium’s board chairman. Faulkner’s second fraud business has therefore drawn on people who had already worked on the first.
The investor story adds another set of connections. Darwinium announced an initial $10 million funding round in November 2022, led by Blackbird alongside Airtree, with angel support including Naval Ravikant and Jeff Fagnan. In October 2023, it announced an $18 million Series A led by U.S. Venture Partners, with existing investors participating.
Alongside the financing came a less conventional presentation detail. The Darwinium team won the Merchant Risk Council’s 2023 Ignite Award. Faulkner described the pitch as showing edge-based security and fraud prevention through a David Attenborough dystopia. Corporate software occasionally allows itself a wildlife documentary. In a business named partly for evolution, the costume at least fits.
His advice to entrepreneurs is more everyday. Put the company’s purpose at the center, include people in the conversation, and absorb advice before deciding which parts to act on. He has argued that ideas can come from anyone. Listening, in this account, requires neither automatic obedience nor the performance of already knowing everything.
That connects neatly with the business he is building. A useful observation needs a route to someone who can act on it. Inside a team, that means making room for contributions. Inside a fraud system, it means letting evidence from one interaction inform another. Both arrangements become less effective when their parts refuse to talk.
When the customer sends software
By July 2025, Darwinium was making the AI contest explicit. It introduced Beagle, designed to simulate adversarial behavior across customer journeys, and Copilot, an assistant for working with fraud signals and decisions. The company described Beagle as testing defenses against activities such as synthetic identities, credential attacks and behavioral imitation.
These are company-described capabilities, and their purpose is straightforward: give defenders a way to rehearse against automated opposition. Faulkner’s wider point is that automation has acquired several motives. A useful agent shopping for a customer and an attacker’s software may both arrive without a human operating each click. Their treatment needs to depend on more than the fact of automation.
In March 2026, he discussed that problem with Alan Shimel on Techstrong TV. Agentic commerce adds a legitimate participant to a category businesses once had stronger reasons to reject. A service that simply closes the door to automated visitors risks excluding people who have chosen to delegate some of their online activity.
The next question becomes whether an agent’s behavior remains consistent with its authorized task. Searching, accessing an account and initiating a payment carry different consequences. Faulkner’s longstanding interest in the surrounding journey finds another application here: recognizing the visitor starts the assessment, while the visitor’s subsequent choices keep changing it.
Darwinium’s October 2026 network update gives that argument a contemporary backdrop. The company reported analyzing 5.4 billion events since May 2025 and identifying more than 30,000 logins associated with agentic activity. It cautioned that the observations reflect its customers’ traffic and integration choices. The figures describe that network, rather than the whole internet.
For Faulkner, the through-line remains a person trying to use a service without becoming somebody else’s opportunity. The technology around that person has changed, and sometimes the person now sends an agent ahead. His work keeps returning to the sequence: what happened before, what is happening now, and whether the next step deserves trust. A familiar face opens the account. The story continues after the door.
