In a public post announcing the move, he warned that attackers can run open-weight AI models at near-zero cost while defenders must pay retail prices for frontier models, a gap he calls the coming economic core of cybersecurity — coining the phrase 'Patch Tuesday will lead to Ransom Wednesday.' Cognition plans products that automate secure software development, including tools to modernize legacy enterprise code and its SWE-1/SWE-2 models plus a Devin Security Swarm tool. Cognition's valuation recently doubled to $48bn, and SpaceX reportedly attempted to acquire it in August. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Who is Cognition's new chief information security officer? Alex Stamos, former security chief at Yahoo, Facebook, and SentinelOne, joined Cognition (maker of the Devin AI coding agent) as CISO. He will help defend Cognition against cyberattacks and help ship new security products, including tools that automate secure software development and modernize legacy enterprise code. _Developers tracking who's shaping AI coding tool security can follow moves like this on daily.dev._ ### Why does Alex Stamos think AI will worsen ransomware attacks? He argues attackers can run open-weight AI models on cheap hardware at almost no cost, while defenders must pay retail prices for frontier models and still fix decades of legacy code. He summarized this economic imbalance as 'Patch Tuesday will lead to Ransom Wednesday,' predicting ransomware groups will automate every step of their attacks. _Teams weighing AI's security risks and costs can keep up with this debate through daily.dev._ ### What security products is Cognition building for Devin? Cognition is developing tools that automate secure software development, including systems that rewrite legacy enterprise code into modern, containerized architectures. It is also building cheaper in-house models, SWE-1 and SWE-2, alongside a tool called Devin Security Swarm, positioned as more affordable alternatives to frontier AI models for security work. _Engineers evaluating AI coding agents for security work can track Cognition's roadmap via daily.dev._ ## Similar posts on daily.dev - [AI coding startup Cognition raises $1B at $25B pre-money valuation](https://daily.dev/posts/ai-coding-startup-cognition-raises-1b-at-25b-pre-money-valuation-fktfezgji) · TechCrunch · 0 upvotes · 0 comments - [Cognition raises $1B at $26B valuation for AI coding agent](https://daily.dev/posts/cognition-raises-1b-at-26b-valuation-for-ai-coding-agent-sutswmzkz) · The Next Web · 0 upvotes · 0 comments - [AI coding startup Cognition reportedly already in talks to raise at $40B valuation](https://daily.dev/posts/ai-coding-startup-cognition-reportedly-already-in-talks-to-raise-at-40b-valuation-cxpouh2yw) · TechCrunch · 2 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#ai-security](https://daily.dev/tags/ai-security), [#devin](https://daily.dev/tags/devin) [View this post on daily.dev](https://daily.dev/posts/alex-stamos-joins-cognition-to-make-ai-security-affordable-bahwydmah) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Alex Stamos joins Cognition to make AI security affordable","url":"https://daily.dev/posts/alex-stamos-joins-cognition-to-make-ai-security-affordable-bahwydmah","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/alex-stamos-joins-cognition-to-make-ai-security-affordable-bahwydmah"},"datePublished":"2026-09-30T16:55:28.317Z","dateModified":"2026-09-30T16:56:19.055Z","description":"Alex Stamos, former security chief at Yahoo, Facebook and SentinelOne, has joined Cognition (maker of the Devin AI coding agent) as CISO.
