Tomer Weingarten shared thisOur goal was always an autonomous platform that gives human defenders a decisive advantage against machine speed attacks. It matters even more in the AI moment. Customers are demanding platforms that create visibility into AI activity and deliver runtime security outcomes across endpoints, cloud, data and identities. That’s what we make possible in any environment, open or regulated, sovereign, or public cloud. This is technology leadership in securing the AI era. Q2 FY2027 highlights: $1.218B Total ARR (+22% YoY) $292M Revenue (+21% YoY) 22% Net New ARR in H1; record second-quarter growth 10% Operating Margin (non-GAAP); ~820 bps improvement YoY $0.08 EPS, non-GAAP (+100% YoY) Triple-digit AI Security ARR growth To our customers, partners, and Sentinels, thank you. You are defining the security platform of the future. Read the press release: https://s1.ai/paga2

Tomer Weingarten shared thisThe frontier is changing. A powerful model escapes controls- autonomously. Open-source models match frontier performance in coding, and regardless of distillation (a fact of life, here to stay, and not unique to any one lab or model), they introduce impressive new architectures for more expressive residuals (AttnRes), attention (Delta Attention, hybrid linear), and scaling (Stable LatentMoE, 16 of 896 experts active). Not just sheer size. They even claim to show that with these architectures, efficiency improves as more parameters become computable (~2.5x prior-generation scaling efficiency at 2.8T parameters). That said, hallucinations are still there. Accuracy far from perfect. Our SentinelLABS team just put out incredible research that directly evaluates reasoning quality, not just autonomous task completion, on long-horizon malware analysis, across the models we have access to. The results point at where the frontier is focused right now. As AI moves into security operations, the key question is: can a model be trusted to carry an investigation forward without losing track? And does that autonomy stay inside the boundaries we set for it? Read about it all on Bloomberg- the escape, the open models, and our research, in one piece: https://lnkd.in/dt_78xA2 The full research: https://lnkd.in/dKGKb5is

Tomer Weingarten shared thisAutonomous agentic investigations. Running in your existing platform. Using your existing workflows. Zero configuration. Complete transparency and control. Frontier-AI-level reasoning. This is the agentic SOC. And it’s here today, in production. 🟣 Meet Purple AI Agentic Investigations. With Agentic Investigations, once a critical alert crosses the threshold, Purple AI acts: zero-click, autonomous. A verdict with a complete evidence chain, before your analyst opens the console. You choose the level of agentic and automated response. You choose where to put human-in-the-loop gates. Adversarial use of AI is about to make the investigation gap exponentially worse. Stretched capacity. The queue grows. Triage waits. Coverage drops exactly when adversaries know to move. A complimentary trial is available to all customers now. Test drive it. Turn it on. Turn it off. You are in control. Frontier AI has entered the SOC. The agentic SOC is GA today. s1.ai/agentic

Tomer Weingarten shared thisSecuring AI means securing the endpoint. Seeing SentinelOne named a leader in the 2026 Gartner® Magic Quadrant™ for Endpoint Protection Platforms - for the sixth consecutive year, is a real proud moment. When we founded SentinelOne, we made a foundational decision: that the future of cybersecurity needed to be fought on the machine, at machine speed. That decision is even more true today. Autonomous protection. AI defense. Built for the threats defining this era, not the last one. Thank you to our incredible team, our partners, and our customers who trust us every day to protect their most critical assets. Read the full report: https://s1.ai/GrtnrMQ26

Tomer Weingarten shared this~50% of SentinelOne's ARR now comes from emerging solutions. That's what platform expansion looks like. When we set out to build SentinelOne, we had one focus – an autonomous platform capable of stopping novel threats, responding to adversaries moving at machine speed, and protecting an expanding attack surface. This quarter, AI, Data, and Cloud reached half of our total ARR. The thesis has become the business. Q1 FY2027 highlights: $1.163B ARR (+23% YoY) $277M Revenue (+21% YoY) Record net new ARR growth 4% Operating Margin (non-GAAP), ~550 bps YoY 22% Adjusted FCF Margin, ~230 bps YoY $0.04 EPS, +83% YoY We also launched Purple AI Auto-Investigations — moving SecOps from AI-assisted to AI-autonomous. Machine-speed defense at the scale and intelligence required for today’s AI powered world. It’s the promise of autonomous security and the Agentic SOC realized today. To our customers, partners, and Sentinels — thank you. We're just getting started. Read the press release: https://s1.ai/Q1-27-PR Listen to the call: https://s1.ai/Q1-27-Ern

Tomer Weingarten shared thisAnthropic + SentinelOne. Frontier model. Frontier operators. Real threats, stopped before they become attacks. Assess instantly and reduce risk in days, not months. In the era of frontier AI models, what matters is speed, and actionability. Identify the real risk - mitigate it instantly. Put defenses to work at machine speed. This is the true power of technology. Today, we are unveiling that loop. I’m incredibly proud to announce Wayfinder Frontier AI Services. This is a significant leap forward in our partnership with Anthropic. We’re fusing Claude Security with SentinelOne’s elite offensive and defensive experts to create a continuous loop of discovery and defense. Continuous discovery using the world’s most advanced models to find real exploitability, not paper risk. Active mitigation that breaks attack chains before adversaries can exploit them. https://s1.ai/Claude-WF

Tomer Weingarten shared thisThe name "fast16" appeared in the 2017 ShadowBrokers leak with one instruction to operators: "Nothing to see here — carry on." For twelve years, nobody knew what it was. Until now. "...the most subtle form of sabotage ever seen in an in-the-wild malware tool: By automatically spreading across networks and then silently manipulating computation processes in certain software applications that perform high-precision mathematical calculations and simulate physical phenomena, Fast16 can alter the results of those programs to cause failures that range from faulty research results to catastrophic damage to real-world equipment..." Tremendous work by Vitaly Kamluk and Juan Andres Guerrero-Saade (JAGS) to uncover fast16 — a cyber sabotage framework whose core components date to 2005. Five years before Stuxnet. The first of its kind. Read on WIRED: https://lnkd.in/geVNkZk9 Read the blog: https://lnkd.in/gaFGG_WB SentinelOne

Omer Perchik and all, I hear you as a fellow Israeli, and I understand your concerns. Knocking down bridges is easy, building them is hard. Disengagement doesn't advance the values we hold. Influence does. You can't shape what you refuse to touch. Partnerships are commitments to shared customers, not political statements. Our responsibility is security. And keep in mind- strategy is not defined by a single action. I'm happy to set some time to chat with you all and hear what's on your mind. Send me a message and we'll set it up.

Tomer Weingarten reacted on thisTomer Weingarten reacted on thisToday is a big day. Alice has raised $140 million, led by Apax Digital. What you can see in this number is nearly a decade of work on problems most people preferred not to look at. Fraud, abuse, manipulation and cyberattacks, hunted across the biggest platforms on earth. We took the worst things online and turned them into something good: Rabbit Hole, the largest collection of real-world adversarial behavior ever assembled, repurposed for protection. Today that work protects 8 of the 10 leading AI labs and almost half of the world online. None of it happened by itself. Alice team, this is yours. You did the unglamorous work for years before AI security was a category, and you did it because it mattered. To our customers: you trusted us with your hardest problems early, and that trust built this company, and more. AI is the greatest expansion of human capability in our lifetime. Everything is possible, and that is exactly why anything can go wrong. And here is what I believe about what comes next. The companies that will win with AI are the ones that can trust their systems to do exactly what they are supposed to do. My years in this new and exciting field taught me that security is not what slows AI down. Security is what lets AI move faster into the real world. That is our job: testing models before they launch, securing agents as they act, and growing Rabbit Hole so defenses evolve as fast as attacks do. Help the world advance, unafraid. A last thank you to our investors, new and longstanding, for your trust, partnership and friendship: Apax Digital, Samsung Research, SentinelOne + Tomer Weingarten, Maj Invest, MoreTech Ventures, Phoenix Financial, alongside CRV, Grove Ventures, Norwest, Highland Europe, Vintage Investment Partners, Resolute Ventures, Claltech and NFX. We're just getting started. AI is shaping the future. We're proud to make it safer.

Tomer Weingarten liked thisTomer Weingarten liked thisLong-running AI agents have a memory problem. Every turn produces useful information, but the weight of that additional context creates noise and increases costs. The frontier labs answered with compaction. A summarization pass over prior agent actions that carries state forward without losing the key learnings. To test this important capability SentinelLABS applied OpenAI's compaction to our reverse engineering harness. The results were impressive: - Input tokens fell 86%. - Output tokens fell 31%. - Reasoning tokens fell 33%. Each run needed fewer model calls, but the aggregate evaluation scores stayed the same. This blog digs into what those numbers mean architecturally. Compaction pushes every developer toward the same decision: what lives in the context window, and what lives in retrievable storage? We land in a clear place. Working memory belongs in context. Evidence belongs in durable storage. Long-running agents were expensive and noisy to evaluate at scale. Compaction changes both, and it moves context engineering from a nice-to-have into the core of how these systems get built. https://s1.ai/CE-Compact
