"You can stay true to yourself and still succeed." For Andrea Mesen, Manager, FP&A at SentinelOne, her Costa Rican heritage has shaped one of the qualities she values most in her career: building genuine relationships. Andrea brings a people-first mindset to every partnership. She makes time to know the colleagues behind the work, build trust, and create the kind of relationships where teams can collaborate openly. In a role centered on budgets and business decisions, that human connection has made her a stronger partner to teams across SentinelOne. That approach reflects the culture she grew up in, where community means genuinely caring for the people around you. Those values have shaped how she leads and grows, turning what might look like a soft skill into one of her greatest professional strengths. This Hispanic Heritage Month, we're proud to celebrate Andrea and the perspective she brings to SentinelOne: staying true to who you are can strengthen the way you connect, collaborate, and lead. 👉 Read Andrea's story: https://s1.ai/HHM-2026

The hacker. The FBI agent who caught him. Same keynote stage. Hector Monsegur and Chris Tarbell spent years on opposite sides of the most consequential cybercrime cases of the past decade. Now they co-host Hacker and the Fed, and in October, they bring that conversation to OneCon 2026. The full speaker lineup is live. See who else is taking the stage: https://lnkd.in/gCB5ibaf

Security was an afterthought during the AI buildout. The September edition of Code Purple covers what it takes to contain what's been unleashed. Part 1 of the September edition of Code Purple is live. Inside this newsletter: 🎙️ The AI Reckoning: Tomer Weingarten went on CNBC as the AI slowdown debate peaked. His take: we're now facing what he called "a huge oil spill that we now need to contain." Model companies and the enterprises deploying AI at scale both need to own the consequences. 🔬 SentinelLABS in Reuters - Inside the Hugging Face Agent Accounts: SentinelLABS identified two Hugging Face accounts tied to OpenAI's May 2026 agent activity: 0Time and Nyx9. Their commit histories reveal relay code predating OpenAI's reported timeline, document-based infrastructure probes, and a tool built to automate illicit ChatGPT account provisioning. ✈️ Customer Spotlight: Yahoo: 400,000 endpoints secured in four months, forensic investigations cut from days to minutes.

🚨 This week, cybercrime hit global DDoS infrastructure, frontier AI development, and autonomous agent sandboxes. 🚦 The Good: Law enforcement extradited Black Axe cybercrime leaders and the FBI seized NightmareStresser, a massive DDoS booter platform responsible for hundreds of thousands of attacks. The Bad: Rising AI risks and fears over recursive self-improvement and models bypassing human safety guardrails are spurring Frontier AI leaders to call for pacing controls. The Ugly: SentinelLABS revealed that autonomous OpenAI agents on Hugging Face operated two weeks earlier than disclosed, building proxy relays and account-provisioning tools. This was the week in cyber.

"I want my kids to know the sacrifices that made their lives possible." For Alex Cruz, Senior Director of Global Sales Enablement at SentinelOne, Hispanic Heritage Month is an opportunity to reflect on the generations that came before him and the values they carried forward. Alex's grandparents left Cuba and Puerto Rico in search of a better future, arriving in the United States with hope, resilience, and a willingness to start over. Their determination created opportunities for the generations that followed, and it's a legacy Alex is committed to carrying forward. Today, those same values shape how he leads. Helping teams around the world succeed, mentoring the next generation of talent, creating opportunities for people from all backgrounds. For Alex, hard work, resourcefulness, and resilience are the values that open doors, and the ones worth passing on. This Hispanic Heritage Month, we're proud to celebrate Alex and the reminder that every opportunity we have today is built on the sacrifices of those who came before us. 👉 Read Alex's story: https://s1.ai/HHM-2026

"These models don't have any judgment, they don't know how to discern, and we're now seeing time and time again that they kind of go on their own path. They veer, they do what they want to do, and it's incredibly hard to keep them on track," — Tomer Weingarten, CEO of SentinelOne, on CNBC. Tomer joined Kelly Evans on CNBC to talk about the wave of "model misalignment" disclosures coming out of the frontier labs this week, and why chasing capability without building security in from day one is starting to look like a cleanup job nobody planned for.

Featured in Reuters, SentinelLABS identified two Hugging Face accounts associated with OpenAI’s May 2026 agent activity: 0Time and Nyx9. Their public histories reveal previously unreported communication relay code, document-based infrastructure exploitation probes, and a Chinese ChatGPT illicit account-provisioning tool, with commits matching OpenAI’s timeline down to the minute. The research expands the public record while separating staged capability from proven execution and the May activity from the later July compromise. Read the investigation: https://s1.ai/mrrfu

We're proud to be named an AI Security Platform Leader in Latio's 2026 AI Security Market Report. AI security is moving from the browser to the endpoint, as tools like Claude Code and Codex become the new front line. Latio's 2026 AI Security Market Report named SentinelOne a Platform Leader for staying ahead of that shift, governing MCP permissions and agent activity down to the tool call. One platform. Browser, endpoint, and first-party AI, together. Read the full report: https://lnkd.in/gMMMSdaB

🚨 This week, the DOJ disrupted the Xinbi scam marketplace and seized $52 million in laundered crypto in one day, multiple APT groups chained three patch-gap zero-days in Windows and Chrome through a new exploit kit called “BlueMoon”, and the NSA, CISA, and FBI accused at least six China-based AI firms of extracting billions of tokens from U.S. frontier AI models at industrial scale. 🚦 The Good: The DOJ's Scam Center Strike Force seized Xinbi Guarantee, a Telegram-based marketplace selling custom scam websites, money laundering services, and trafficking victims to Southeast Asian fraud compounds restraining $52 million in crypto in a single day and bringing its total to $938 million, while a deployed team in Madagascar assisted in the takedown of 13 Chinese-run scam compounds and the processing of 3,200+ seized electronic devices. The Bad: Researchers disclosed BlueMoon, a shared modular exploit kit used by at least four threat actor clusters, including APT31 that chains three zero-days in Chrome's V8 engine and Windows ALPC to achieve browser-to-kernel code execution and deliver credential stealers, the ShadowPad backdoor, and in-memory implants against NGOs, aerospace, defense, and manufacturing targets. The Ugly: The NSA, CISA, and FBI jointly accused at least six Chinese AI firms including DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI of extracting billions of tokens from U.S. frontier models including Claude, GPT, Gemini, and Grok at industrial scale, using chain-of-thought extraction, VPN obfuscation, and automated failover to replicate restricted capabilities and compress AI development timelines without the legal and regulatory constraints binding U.S. companies. This was the week in cyber.
