Last week, more than 100 companies and organizations published an open letter calling for a rapid acceleration of cyber defense capabilities to combat the capabilities of AI. The list reads like a procurement catalog. Microsoft, Google, AWS, Cisco, IBM, CrowdStrike, Cloudflare, Anthropic, Okta and Fortinet are on it, alongside buyers like Mastercard, Visa and Capital One. The public signatory page has since passed 200 companies and organizations, with some such as 1Password, Sophos and Prophet Security, have already published posts of their own detailing their commitment to defenders.

The explanations are worth sitting with. Letters turn into marketing assets faster than they become company concrete action. The buyers decide which one becomes reality.

The diagnosis is correct

I want to be careful about how the skepticism below reads, because the letter has the substance right. It opens by arguing there is a limited window to strengthen defenses before AI-enabled attacks become widespread. There is data to back that up. CrowdStrike’s 2026 Threat Hunting Report, covering January through June 2026, found that 88 percent of the exploitation it observed against vulnerabilities with a public proof of concept occurred within 48 hours of that proof of concept being published. In the four days after the React2Shell disclosure, the same team logged more than 800 hunting leads across over 80 victim organizations.

Forty-eight hours is shorter than most change windows. Anyone who has sat through a Thursday patch approval meeting knows what that does to a quarterly remediation cycle.

The shrinking timeframe is real.

What the document does not contain

The letter lays out three principles and addresses four audiences: cybersecurity companies, governments, frontier AI companies, and every other organization. While it reads well, it carries no deadlines, dollar figures, measurable targets or expiration date. There is nothing to measure, therefore, there is no way to determine the initiative’s failure.

There is something else worth calling out. Several of the firms warning about AI-enabled attacks are selling AI-enabled defense into the same budget cycle. Both OpenAI and Anthropic have been touting their cybersecurity-focused models since the spring, and most of the large security companies on the signatory page sell their own AI defense product. Those are commercial products competing for the same security budget the letter is asking you to expand. The letter’s warning doesn’t suddenly become false, and I don’t think it was written in bad faith. However, both the warning and the pitch arrived in the same envelope, and a buyer who reads only one of those messages will overpay.

The one line worth extracting

Buried in the section addressed to cybersecurity companies is the only sentence that behaves like a standard. The letter asks those companies to “share threat intelligence and tested playbooks, and measure progress by how many organizations are protected, how quickly attacks are contained, and whether fixes work.”

That is three metrics. Coverage, containment speed, and verified remediation. Every security vendor on the signatory list endorsed them in public, under its own logo, in a document it chose to promote.

The section addressed to every organization gives buyers the matching instruction—raise the security bar for what you buy, build and deploy, including AI-generated code.

Put those together and the rubric was already in the room. It just came in through public affairs instead of procurement.

Five questions for your next renewal

Take the letter to the vendor that signed it. Ask for evidence against its own asks.

What share of your installed base is actually running the AI-enabled defenses described here? What does that capability cost above the current contract? Coverage claimed in a letter and coverage sold in a SKU are rarely the same number, and the gap between them is where the upsell lives.

What is your median and 95th percentile time to contain, measured your own telemetry, this year versus last? The letter says to measure containment speed, so any vendor that signed it has already agreed the question is fair.

What is your retest rate, and how many remediations failed verification on the first attempt? “Whether fixes work” is the third metric in that sentence, and the one almost nobody reports.

The letter commits signatories to making AI-powered defense deployable for critical infrastructure operators with hands-on help. What does that program cost a 200-bed rural hospital, and how many are enrolled today?

Finally, turn the buyer instruction back on the seller. What proportion of your own product is model-generated code, and who reviews it before it reaches my environment?

All of the signatories endorsed every idea across all five of these questions.

The honest read

None of this argues against the letter. Coordination documents do real work: they create a public position people can be held to eighteen months later, and the diagnosis in this one is more candid than most vendor marketing on the subject. Signing cost nothing as of Aug. 27, which is why more than a hundred organizations were willing to do it.

The cost shows up at renewal, and only if someone on the buying side treats the signature as a commitment. Otherwise, it is a logo on a webpage and a line in a blog post nobody reopens.

Two hundred companies agreed to measure progress. Put the question in your next renewal and one meeting will tell you which of them meant it.
