On Saturday, October 10, Satya Nadella published a post on his personal blog titled “Models as Insider Risks in the Super Intelligence Era,” then shared it with his LinkedIn followers in one line. Microsoft’s chairman and CEO told enterprises to treat frontier models, closed and open-weight alike, the way they already treat a powerful insider. That means an established identity, limited privileges, logged activity and containment boundaries, plus a tamper-proof record of everything consequential a model does, written so a person can read it. Someone with authority has to be able to stop a model mid-task. He called that an emergency brake.
The sentence worth framing is shorter. “We simply can’t outsource responsibility for what intelligence does on our behalf.” Microsoft sells intelligence. Its CEO just told the people buying it that the responsibility stays with them.
He has reason to know. In June 2025 Microsoft fixed CVE-2025-32711, a flaw researchers named EchoLeak, in which an email nobody had to open could steer Microsoft 365 Copilot into leaking data from a user’s context the next time that user asked it a routine question. Microsoft scored it 9.3 out of 10. There’s no evidence anyone exploited it before the fix. Sixteen months later, the company’s CEO is telling customers to assume the model is already compromised and to build the containment in from day one.
I made the same argument here in July:
I Asked an Uncensored Model Three Questions. What It Said Convinced Me We Need a Kill Switch.
I ran a small experiment last week. Not a jailbreak, not a red-team exercise, nothing clever. I asked an “uncensored” fine-tune three questions and watched what it did with them. The model was one of those community builds that advertises itself as unshackled, unfiltered, free of the corporate hand-wringing that supposedly ruins the commercial models. T…
Down to the decade the controls come from. An audit trail the agent can edit isn’t an audit trail. It’s a narrative. The difference between my post and his is reach. When a practitioner writes that agents need a brake the model can’t touch, it’s an opinion. When Microsoft’s CEO writes it, it’s notice.
Notice is the word lawyers care about. After Saturday, an executive who signs a cybersecurity certification can’t tell a regulator, a jury or a Delaware judge that nobody warned them an AI agent could behave like a compromised employee. The warning came from the vendor. That would matter less if executives weren’t personally on the hook for cyber failures. They are, and the hook is getting sharper.
The SolarWinds Dismissal Was Not a Pardon
On November 20, 2025, the SEC dismissed, with prejudice, its fraud case against SolarWinds and its chief information security officer, Timothy Brown. Filed in October 2023, it was the first time the Commission had named a security executive as an individual defendant. Judge Paul Engelmayer had already thrown out most of it in July 2024. In April of this year, the major banking trade groups wrote to the SEC asking it to rescind its cyber disclosure rules.
Boardrooms read that sequence the convenient way. The government blinked, personal cyber liability was a 2023 scare, and whoever signs the security paperwork can relax. It’s a comfortable reading. It’s also wrong.
On June 29, 2026, the Supreme Court declined to hear Joe Sullivan’s appeal. Sullivan was Uber’s chief security officer in 2016, when attackers stole data on 57 million Uber users, including license numbers for about 600,000 drivers, while the FTC was already investigating Uber over an earlier breach. He paid the attackers $100,000, called it a bug bounty, and had them sign nondisclosure agreements. A federal jury convicted him in October 2022 of obstruction and misprision of a felony. Prosecutors asked for fifteen months in prison. He got three years of probation and a $50,000 fine, the Ninth Circuit affirmed in March 2025, and with certiorari denied the conviction is final. Sullivan wasn’t convicted for being breached. He was convicted for what he told the government afterward, and what he didn’t.
The FTC took a different route with Drizly. In 2020 attackers got into Drizly’s GitHub through an executive whose access had been granted for a one-day coding event and never revoked. The executive had reused a password that leaked in an unrelated breach. The repositories held AWS credentials, and the attackers left with records on about 2.5 million customers. The order the FTC finalized in January 2023 follows CEO James Cory Rellas personally for ten years. Any company he joins as majority owner, CEO or senior officer responsible for security that collects data on 25,000 or more people has to have an information security program, and he has to implement it. A one-day coding event. Ten years.
Those are the cases people cite. The bigger change is quieter. Liability has moved off the prosecutor’s desk and onto the signature line, where nobody has to blink.
New York’s Department of Financial Services has required an annual Part 500 compliance certification since the rule took effect in 2017. Since the 2023 amendments, the company’s highest-ranking executive and its CISO both sign it by April 15, stating that the company materially complied in the prior year or admitting in writing where it didn’t. DFS has shown what it does with a signature it doesn’t believe. In 2022 it fined EyeMed $4.5 million after a phished mailbox exposed six years of customer data. Nine employees shared that mailbox’s password. It had no multifactor authentication. Because EyeMed’s risk assessment never addressed the mailbox, DFS treated the assessment as inadequate and deemed four years of certifications, 2017 through 2020, improper. EyeMed argued good faith. DFS wasn’t interested.
California added its own signature line this year. CCPA regulations in effect since January 1 require independent cybersecurity audits for businesses whose processing presents significant risk, and a member of executive management certifies each one to the California Privacy Protection Agency under penalty of perjury. The auditor can’t lean mainly on what management says. Businesses over $100 million in revenue certify first, by April 1, 2028, for calendar 2027. That year starts in less than three months.
Defense contractors got theirs on November 10, 2025, when CMMC went live. A senior executive, the affirming official, attests in the government’s SPRS system that the company has implemented every applicable CMMC requirement and will keep it that way, and repeats the affirmation every year. A false one is a False Claims Act problem, which means treble damages, per-claim penalties and whistleblowers who collect 15 to 25 percent of the recovery. The Justice Department didn’t wait for CMMC. In 2025 it settled allegations against a contractor that had reported a positive SPRS score when the real number was negative 142, and against Georgia Tech’s research corporation over a false score and a lab handling controlled defense information without anti-malware tools.
Europe put it in the directive. NIS2 requires management bodies to approve and oversee cybersecurity risk measures and to take training, and it lets them be held liable for infringements. For essential entities, regulators can seek a temporary ban on a person exercising managerial functions at CEO level. Germany’s implementing law took effect on December 6, 2025, with personal liability for management written in.
Even Microsoft moved the money. A month after the federal Cyber Safety Review Board called its security culture inadequate in April 2024, it tied part of its senior leadership’s compensation to security, and Nadella’s memo to employees settled every tradeoff in two words. “Do security.”
None of these regimes needs an enforcement director with an appetite. They need a signature, and somebody in your company has already given one.
The New Insider Takes Instructions From Strangers
AI makes all of this worse. Not mainly because attackers got faster, though they did.
In November 2025 Anthropic disclosed that a group it assessed as Chinese state-sponsored had used Claude Code to run an espionage campaign against roughly 30 organizations, with the model doing an estimated 80 to 90 percent of the tactical work at request rates no human team could sustain. In April, Anthropic said its restricted Mythos Preview model had found thousands of high-severity zero-days across every major operating system and browser, including a bug that had sat in OpenBSD for 27 years. In July, Hugging Face disclosed that an autonomous agent framework had come in through a poisoned dataset, stolen cloud credentials and moved laterally across internal clusters. IBM’s 2026 breach study put a price on it. One in four malicious breaches was AI-enabled, and those averaged $6 million against $4.99 million for breaches overall. In a follow-up, 85 percent of those breached organizations said they planned to spend more on security after learning what frontier models can do. After the breach itself, 64 percent had. The breach was less persuasive than the headlines.
The bigger problem sits on your side of the firewall, and you paid for it. An AI agent is an insider by construction. It holds credentials, reads your data, takes actions, and accepts instructions from any text that reaches its context window, including text written by people who want what it can reach. That was EchoLeak. It was also Salesloft. In August 2025 attackers used OAuth tokens stolen from the Drift AI chat agent’s Salesforce integration to export records from customers’ Salesforce instances. Google’s threat intelligence group counted more than 700 potentially affected organizations and found the attackers combing the stolen data for AWS keys, passwords and Snowflake tokens. A month later, researchers found an npm package called postmark-mcp, an MCP server impersonating the email company Postmark. Version 1.0.16 added one line that blind-copied every email it sent to an address the attacker controlled. It had been downloaded 1,643 times.
The attacker can also wear an executive’s face. In early 2024 an Arup employee in Hong Kong transferred HK$200 million, about US$25 million, after a video call on which the CFO and the other colleagues were all deepfakes. IBM found that more than one in five organizations reported a breach aimed at their AI models or applications, with compromised APIs, apps and plug-ins and misconfigured cloud AI workloads each behind 27 percent of them.
New York wants notice within 72 hours of determining that a cybersecurity incident occurred. A public company has four business days from deciding an incident is material to file its 8-K. NIS2 wants an early warning inside 24 hours. Every one of those clocks assumes somebody can say what happened. When a human insider goes bad, there are badge records, VPN logs and an HR file. When an agent goes bad, there’s whatever its builders chose to record, and if the tool calls weren’t logged somewhere the agent can’t write, the 72 hours get spent reconstructing events from the model’s own account of itself.
DFS saw this coming. Its October 2024 industry letter told regulated companies that AI belongs in the Part 500 risk assessment, including the company’s own AI, its vendors’ AI, and deepfake-driven social engineering. The letter says it adds no new requirements. It didn’t need to. EyeMed lost four years of certifications over one mailbox its risk assessment skipped. A risk assessment that skips the agent holding your CRM token is the same mailbox with a language model attached.
Nadella’s principles read differently to anyone who signs things. He wants evidence of every meaningful action that the model can’t alter, access controls the company sets independently of the model, validation that doesn’t come from the thing being validated, and a brake a human can pull mid-task. A regulator would call that list an audit scope.
What a Brake Looks Like When It Ships
I build these systems, mostly on the Microsoft stack Nadella runs. The agent I built for a Las Vegas wedding chapel takes deposits, which puts it inside PCI scope. The model never sees a card number. It can trigger a tokenized payment step, and that’s the whole of its authority over money. Human planners watch conversations live in a supervision portal and can take over mid-thread. Nobody on the project called it an emergency brake. It was the condition the business set before it would let the agent talk to a customer.
Every tool an MCP server exposes is a permission, and every tool description is an instruction the model will follow, written by whoever controls the server. That’s why postmark-mcp worked. Nothing in the agent was broken. It did exactly what its tools told it to do, and one of its tools belonged to someone else.
The rest is unglamorous. Each agent gets its own identity instead of a borrowed service account. Read access is scoped to the job. Writes are few, and every one has a name. Every tool call, parameter and result lands in a store the agent can’t write to, and tokens get revoked from outside the model, so when the control plane can’t reach an agent, the agent stops. Failing open keeps the demo alive. It keeps the attacker alive too.
I’ve spent most of my career building payment systems inside PCI scope, from a tokenized card vault for Lenovo to ShopSnap, where compliance gets validated every year whether anyone’s in the mood or not. Agents are walking into that kind of regime now. Almost everything they need was worked out decades before anyone had heard of a transformer.
The Audit Is the Record the Court Reads
In October 2021 the Delaware Court of Chancery dismissed a Caremark claim against Marriott’s directors over the Starwood breach, which exposed data on up to 500 million guests. The directors won with paperwork. The board and its audit committee had received regular cybersecurity updates and annual cyber-risk reports, and had hired outside consultants to audit the company’s practices. Caremark doesn’t ask whether the security was good. It asks whether the people in charge oversaw it in good faith, and Marriott’s record answered the question.
The honest objection is that Caremark claims almost never succeed. When Delaware dismissed the SolarWinds derivative suit in 2022, the court called cybersecurity mission-critical but said it was still an open question whether oversight liability reaches business risk when no law is being broken. Every certification regime above turns cybersecurity into law, and none of them waits for bad faith. A New York certification is accurate or it isn’t. California’s is sworn under penalty of perjury, and the False Claims Act reaches reckless disregard, a lower bar than bad faith by some distance. The bar that protected Marriott’s directors isn’t there on April 15.
The second objection is that an audit creates evidence, and evidence cuts both ways. It does. Since the McDonald’s decision in January 2023, officers as well as directors owe a duty of oversight in Delaware, a CEO’s area of responsibility is the whole company, and a red flag consciously ignored is the claim. An audit that finds problems nobody fixes is a red flag with a date on it. So the audit has to end in a remediation plan with owners and deadlines, and any risk the company decides to live with should be accepted in writing by the person who owns it. A documented decision is defensible. An ignored finding isn’t.
There’s also a way to do this that keeps counsel comfortable. In 2020 a federal court ordered Capital One to produce Mandiant’s forensic report on its 2019 breach, largely because the work looked like business as usual. It ran under a pre-existing statement of work, came out of a business budget and went to about 50 employees, the board, four regulators and the outside accountants. When the point of an assessment is legal advice, counsel should engage the assessor and control where the report goes.
Those three cases are the design spec for how I run security audits at Inverted Software, and the first thing they rule out is doing it once. Marriott’s directors had regular updates and annual reports, not a binder from three years earlier. Agents change faster than binders. A new model version, a new MCP server or a new integration changes what an agent can be talked into, which is why Nadella’s own list calls for testing that continues through every system change. An audit that’s a year old describes a system that no longer exists.
The work starts with a baseline. Every model, agent, MCP server, plug-in, OAuth grant and service account gets an owner and a written answer to two questions, what it can read and what it can do, because the agent nobody listed is the one that ends up in the incident report. Then I test your agents against the techniques behind EchoLeak, Drift and postmark-mcp, using instructions planted in the documents and email they actually retrieve, poisoned tool descriptions, and stolen-token scenarios run against your real integrations. I pick an agent action from last week and ask your team to reconstruct it, including the prompt that caused it, from logs the agent couldn’t have edited. If that takes longer than New York’s 72 hours, it’s a finding. So is a brake nobody has tested, or an agent that keeps running after the control plane goes quiet. The baseline ends in dated findings mapped to the regimes your company certifies under, whether that’s Part 500, the CCPA audit rules, CMMC or NIS2, along with the remediation plan and signed risk acceptances that keep a finding from becoming a red flag, and a board summary in plain English.
After that, the audit runs for as long as the system does. Any new model version, tool, MCP server, integration or permission change gets retested before it ships. Every quarter brings an evidence drill on a randomly chosen agent action, a pull of the brake, a sweep for agents nobody registered, and a short report to the board, the kind of regular reporting the Marriott court credited. Once a year the whole system is re-baselined and the evidence is packaged on the calendar your certifications run on, whether that’s April 15 in New York, April 1 in California or your annual CMMC affirmation, with a tabletop for the executives who’d sign the incident notice, run against the real clocks. If an incident does happen, the people reconstructing what your agents did inside the notification window already know the system.
There’s no rate card. The work is scoped to the size of the system, meaning how many agents you run, what they’re connected to and what data they can reach. If your counsel wants the work privileged, I’ll work under their engagement letter.
No audit can promise you won’t be breached. What it can do is make sure that when you are, the record shows a company that knew what its agents could touch, tested them, logged them, could stop them and fixed what it found, for the whole life of the system. Marriott’s directors had that kind of record.

Satya Nadella says to assume the model is compromised. He won’t be signing your certification either.
