Every time a Mastercard gets tapped, the network has less than a tenth of a second to judge how likely the purchase is to be fraudulent. It made that call across 175 billion transactions last year. Now the buyer on the other side of that judgment is starting to change, and Greg Ulrich, the company's chief AI and data officer, spelled out the consequence for the VB Transform 2026 audience in Menlo Park on July 14. "We've built a bunch of risk rules over time that were intended to stop a bot from transacting," Ulrich said. "Now we need to enable the bot to transact, so that requires a change to our risk framework and our risk rules." Ulrich joined Mastercard eleven years ago when an analytics company he worked at was acquired, and said trust struck him from day one on the job. "It's what enables a merchant that's never met you to accept payment and ensure that they're going to get paid. It's what enables you as a consumer to transact and ensure that things are going to work out in a trusted, secure way. And if something goes wrong, there's a safe and secure path for a dispute and to resolve this," he said. 175 billion transactions, scored in under 100 milliseconds He took the audience inside each of those calls. "When you tap your Mastercard to pay for a product or service, we're providing a score to that transaction," he said. "We have under 100 milliseconds to look at that and give a score from zero to 999 about how likely is that to be fraudulent or real. And we pass that on to the issuing bank." Generative AI widened what that score can see. "Because we have new technology, we can bring in more data, we can bring in more context, and now we're finding that we can identify 300, 400% more fraudulent transactions at those high-risk bands," Ulrich said, without adding friction or false positives for consumers. The company's Safety Net system has stopped more than 70 billion fraudulent transactions, he told the audience, and Mastercard is building its own transformer model on its transaction data as a foundation for new safety, security, and personalization solutions. VentureBeat's Beyond the Pilot podcast took that production fraud stack apart in detail earlier this year. A third of the services business already runs on AI The business stakes reach past fraud. About 40% of Mastercard's company is now based on services, Ulrich said, including marketing services; fraud, safety and security; and business intelligence. "A third of those are predicated on AI, and those are growing at a much faster clip than everything else," he said. One line he returned to all session went further. "What's going to enable AI to continue to scale is not the capabilities of the agents, it's how much we trust those agents to do on our behalf as a consumer, as a business, as a financial institution, or otherwise," he said. Five layers stand between agents and the network Agentic commerce changes the object being secured. "Instead of a single atomic transaction where I say go buy something, I'm effectively delegating authority, or a consumer's delegating authority, a business is delegating authority," Ulrich said. "And when that happens, it's a much more complicated transaction." Trust, in turn, has a precondition. "The only way it's going to work with trust is if we can identify what was the intent, what are the behaviors, what are the constraints that were intended in that transaction." Ulrich walked through five layers Mastercard has built against that problem. Identity comes first. "I want to make sure I can understand not just who the consumer is, but who the agent is, that I combine them together and that I have KYA or know your agent, that I'm validating that it's legitimate technology, that it's a legitimate agent," he said. "We can register it into our system." Verifiable intent settles the "wrong-Nikes" problem Verifiable intent is second, a tamper-proof cryptographic record of the original instructions that travels with the transaction. "If you've asked for Nike black Nikes in size 12, but you got them on a final sale and they're not returnable and that wasn't in your instruction, there's a way to look at that in an objective and clear way on the back end," he explained. Controls form the third layer, defining which merchants an agent can buy from, at what limit, and under what constraints. Execution runs through Mastercard Agent Pay , which carries "the tokenization, authentication, the acceptance framework embedded within it" and has launched with Microsoft, OpenAI, Google, and others, Ulrich said. Intelligence is the fifth layer, spanning risk rules, insight tokens that grant "consented or permissioned access to insights" for personalized recommendations, and monitoring through Recorded Future to identify threat actors in the system. The bigger prize is a procurement agent with a budget Consumer purchases are where agentic commerce started. Ulrich pointed the room past them, to business-to-business procurement as the larger opportunity. His example was a manufacturer that wants an always-on assembly line, with an agent that manages inventory levels, tracks when stock runs low, replenishes automatically, and understands the budget and the approved suppliers. "When you can start enabling that, you require those same five layers for that type of transaction," he said. Making it work across companies multiplies the parties that have to trust each other. "You need clear standards for identity, you need clear standards for intent, you need these to work across. You're gonna have a procurement agent, a supplier agent, a banking agent. They're all gonna need to communicate to enable this to happen in an autonomous way, and that's gonna require really scaled trust infrastructure." Powerful new models, same security motion Mastercard sat in the early wave of Project Glasswing with Anthropic's Mythos model, and worked with OpenAI's GPT-5.5-Cyber , he said. "What we've seen from both of those is incredibly powerful models finding new vulnerabilities in the ecosystem that were difficult to detect previously, but it's really a new tool as opposed to a new motion," Ulrich said. Inside the company, the chief security officer leads that work. A dedicated team has prioritized the most critical assets, runs them through the models routinely, tracks findings by high, medium, and low severity, and uses the same technology to handle patches. Ulrich said the approach has already been extended out, and that Mastercard is working to make the same architecture and patching available to others as well. What Mastercard would build differently after 14 months "The guardrails, the security, all this stuff has to be embedded at the front end. These can't be things that we're adding on at the back end. That's lesson one. Lesson two is you have to be operating for scale, and the other one is around observability and accountability matter as much as the intelligence," Ulrich said, counting off what building inside Mastercard taught the team. The company built what he described as an agentic factory, an operating system with the compliance, the observability, and the guardrails built in rather than bolted on per agent. Model drift, once tracked manually by dedicated teams, is now automated into that factory. Asked by an audience member about the gotchas, Ulrich did not soften the pilot-to-production trap. "If you're trying to extend that and then add guardrails in as you're extending it, once you've already built it, I think you're doomed to fail," he said. Mastercard built a series of agents last year for its 4,000 consultants, covering deep research, text to SQL, Excel, and PowerPoint, tools that by his account did not exist at the level Mastercard needed. Were the company starting today, Ulrich said, it would build them fundamentally differently. "I don't know that we anticipated when we built things fourteen months ago that we would be rethinking the fundamental architecture and the approach already." Agentic identity joins KYB and KYC The identity layer is where Ulrich expects the market to move next. Inside Agent Pay, Mastercard authenticates the consumer the way it does in traditional e-commerce and binds the agent to that person. "Outside of that framework, I think there will be open standards to identify who an agent is and bind the agent with the consumer," he said. "And then we can tie that with verifiable intent." VentureBeat's June 2026 Pulse research points at the same gap. Only 32% of the 107 qualified enterprise respondents give every agent its own scoped, managed identity , and just 12% include an agent-identity product in their consideration set. He called identity "one of the faster-growing ecosystems," noting Mastercard has been expanding there organically and inorganically for about six or seven years, with the work now spanning "agentic identity as well as the traditional KYB and KYC identity." The risk rules that keep bots off the network came out of more than two decades of applying AI to those transactions. The rewrite, for the agents Mastercard now wants to let in, is already underway on the same network that scored 175 billion of them last year.

A lot of security still comes down to trusting the wrong screen. This week, that screen might be a login page, an install guide, a recruiter call, or a familiar service behaving slightly wrong. Behind it: reused credentials, exposed systems, quiet loaders, abused trust, and exploit paths that should have been harder. Some defenses improved. The loose parts still got found first. Anyway,

A security team approving an open-source model for production today starts with a repository page. The page lists the model name, the license, and a tag identifying the base model it descended from. That tag is a string the uploader typed. Hugging Face does not require uploaders to substantiate the claim through weight-level analysis. The ATOM Report , published by Nathan Lambert and Florian Brand at Interconnects AI in April 2026, tracked roughly 1,500 mainline open models. ATOM identifies derivatives through the Hugging Face base_model tag, a field the uploader populates, filtering to models whose base model appears in the tracked list and that have more than five lifetime downloads and excluding GGUF and MLX re-uploads. By that measure, Alibaba’s Qwen family is the declared parent of 69% of new open-model derivatives as of February 2026, up from 1% in January 2024. Chinese labs overall account for 70%. Europe sits at 4%. Cumulative tracked downloads across the three regions reached 2.04 billion through March 2026. The verification gap extends to scan coverage. Cisco Foundation AI scans every public file uploaded to Hugging Face through an updated ClamAV engine, and the platform surfaces a file-level badge per file. Hugging Face’s own malware scanning documentation notes a file with neither an ok nor an infected badge may be queued, still scanning, or errored. At a given review point, a repository may contain files without completed scan results. Coverage has been an assumption, not an attribute anyone could read before approving a model. From command line to public lookup Cisco on Thursday published the AI Supply Chain Provenance Explorer , a free public database covering almost 900 open models. Each entry can carry provider headquarters, a fingerprinted lineage graph, license restrictions, and a files-scanned count. The tool extends Cisco’s Model Provenance Kit , an open-source Python toolkit released in April that fingerprinted roughly 150 base models across 45+ families and 20+ publishers. Coverage grew roughly sixfold in a quarter. The April release was a command-line tool. Running it meant a local Python environment, downloading model weights that run into tens of gigabytes, and dedicating engineer hours per model. The Explorer queries results Cisco already computed. On Thursday, verifying parentage starts with a search bar, and cost is why enterprises run open weights in the first place. Amy Chang, head of AI Threat Intelligence and Security Research at Cisco, has been building the case for why verification gaps matter. During a VB Transform 2026 agentic security panel , Chang presented findings from 6,986 multi-turn attacks against 15 flagship models, with success rates reaching 88.3%. "If you don’t understand how models are susceptible to different types of attacks, then you are unable to account for how that model that is powering your agent, that is powering your application, to understand where those failure points are," Chang told the audience. Understanding failure points starts with knowing which model you are running. The Explorer also surfaces data Cisco already uses operationally. The company’s Cerberus system inspects models entering Hugging Face and feeds Secure Access policies that block by risky license or region of origin. The Explorer makes that class of information free and searchable without a Cisco product. How fingerprinting replaces the tag The Explorer grounds model relationships in similarity scores rather than self-reported metadata. Cisco’s Model Provenance Kit works in two scored stages. Stage one compares architecture metadata before loading any weights. When metadata is ambiguous, stage two extracts five weight-level signals. Embedding Anchor Similarity captures geometric relationships that survive fine-tuning. Embedding Norm Distribution encodes word frequency patterns. Norm Layer Fingerprint reads layers stable across fine-tuning. Layer Energy Profile compares distributions across network depth. Weight-Value Cosine directly compares weight values, and independently trained models show essentially zero correlation on this signal. Cisco reported 96.4% accuracy on its own 111-pair benchmark at a 0.70 threshold, with an F1 of 0.963. Four pairs were misclassified, all involving extreme architectural transformation that Cisco calls a fundamental limit of pairwise weight comparison. Tokenizer signals are computed for diagnostics but deliberately excluded from the provenance score. StableLM and Pythia both use the GPT-NeoX tokenizer and would score as related despite sharing no weight lineage. Excluding tokenizer data prevents false positives. Behavioral fingerprinting adds a second approach. Jonah Leshin, Manish Shah, and Ian Timmis at Project VAIL, working with Daniel Kang at UIUC, published work on behavioral endpoint stability showing that a model endpoint can stay healthy while its effective identity changes through weight updates, quantization, or routing. Cisco’s launch blog states the Explorer integrates both static fingerprinting and behavioral-similarity analysis to ground the lineage graph. Static analysis supplies weight-level evidence of training-time derivation. Behavioral analysis catches runtime identity drift. Where existing tools fall short The Explorer carries real limits. Almost 900 models is a meaningful start, but Hugging Face hosts more than 2 million as of spring 2026. Models outside the boundary still depend on the self-reported tag. Cisco has not said whether the Explorer exposes an API, and without one, a team can look models up by hand but cannot wire the check into a CI gate. That is the line between a governance artifact and a control. Traditional SCA tools face a structural mismatch because they were built for dependency manifests and container images. Sakshi Grover, senior research manager for cybersecurity at IDC, said in CSO Online that traditional SCA "was designed to inspect dependency manifests, libraries, and container images" and "is far less effective at identifying" the risks tied to AI workflows. Gartner director analyst Jaishiv Prakash told the same outlet that enterprises need "dedicated controls for model sources, approved versions, access, and runtime validation at the registry layer." Both were commenting on broader supply chain risks, but the gap they describe is the one the Explorer targets. Cisco’s Model Provenance Constitution defines where one model counts as a derivative of another. The constitution defaults to labeling ambiguous pairs as independent, because a false positive triggers a licensing accusation while a false negative gets caught during manual review. That deliberate conservatism supports the 96.4% accuracy figure. Derivation is not binary, and fingerprinting is one form of evidence alongside documentation and checkpoint verification. What goes in the approval record On August 2, the European Commission gains its AI Act enforcement powers over GPAI model providers, with fines up to 15 million euros or 3% of global turnover, whichever is higher. Organizations that substantially modify and place an open model on the EU market can acquire provider status, with Commission guidance treating modification compute exceeding one-third of the original’s. The Act’s open-source exemption under Article 53(2) requires a genuinely free and open-source license permitting access, use, modification, and redistribution, with weights, architecture, and usage information all public. Public weights alone do not qualify. Llama’s community license carries a monthly-active-user threshold and a disqualifier the Commission guidance names explicitly. Llama and Gemma together account for roughly a fifth of new derivatives in the ATOM counts, and both carry licenses the Commission criteria would likely disqualify. License classification becomes part of the provenance review, and that is exactly what the Explorer surfaces. The board question that arrives first after a base-model vulnerability disclosure is straightforward: "Which of our production models inherits this weakness, and how do we know?" The answer today requires a manual hunt through repository pages, tracing self-reported tags that no weight-level analysis has confirmed. The Explorer converts that hunt into a lookup for the models it covers. Four fields belong in the approval record that most organizations do not carry today. Fingerprint-supported derivation grounded in weight analysis rather than a self-reported tag. A files-scanned count replacing the assumption of coverage with a measurable scan count. Provider headquarters as a filterable field, recognizing that headquarters alone does not resolve export-control exposure, since ownership and deployment location also govern the screening. And license lineage surfaced so legal teams can identify potential upstream terms before a model reaches production. Cisco released the Supply Chain Provenance Explorer today, and it is available at provenance.aidefense.cisco.com . The database is free, public, and does not require a Cisco product or account. What changes for a security team on July 30 What the team has today What the Explorer publishes Recommended action Blast radius after a base-model vulnerability. The model name and the base_model tag. Scoping which models inherit a disclosed weakness is a manual hunt through repository pages. Lineage grounded in similarity scores using two scored stages of fingerprinting on architecture metadata and five weight-level signals. The kit scored 96.4% accuracy at the 0.70 threshold. Attach fingerprint-supported derivation to each model in the asset inventory so a disclosure triggers a scoped review instead of a hunt. Malware scan coverage. A file-level badge per file. At a given review point, a repository may contain files without completed scan results. Coverage has been an assumption. Files-scanned counts and reported malware or unsafe-file findings per model, from ClamAV-based scanning. Scan coverage becomes readable before approval rather than inferred from a badge. Replace the assumption that a model was scanned with the recorded count. Where coverage is partial, document whether the gap is acceptable and why. Provider jurisdiction. An organization name on a repository page. A derivative several steps from its origin displays the uploader, not the ancestor. Provider headquarters, website, and associated HF organizations as a filterable field. Headquarters alone does not resolve export-control exposure. Add jurisdiction to the approval record. Any team that substantially modifies and places an open model on the EU market faces potential provider obligations under the EU AI Act. License obligations. A license tag describing what the uploader believes applies. Terms from a base model upstream may not appear on the page the engineer reads. Common limitations per model, including attribution, non-commercial terms, geographic restrictions, and prohibited use cases. Fingerprinted lineage helps legal teams identify potential upstream terms. Route license lineage to legal before production, not after a contract references it. Document the position at approval rather than reconstructing it during a dispute.
