Cybersecurity stocks have a powerful long-term tailwind because more AI means more complexity, more attack surface and more need for security. CrowdStrike, SentinelOne, Palo Alto Networks, Zscaler, Fortinet, Okta and Rubrik moved up strongly premarket after Anthropic CEO Dario Amodei published an essay arguing the AI industry should slow down, with Anthropic committing to give third-party evaluators permanent access to verify its safety measures. The market may be connecting those dots. x.com 

AI-powered attacks are spreading so fast that companies are unlikely to cut security budgets, even if they slow broader AI spending. The latest wave hit governments, banks, hospitals, grocery chains and businesses, while AI finds vulnerabilities and breaks in around the clock. That is why Cloudflare, Zscaler, CrowdStrike and Palo Alto Networks rose as broader AI concerns hit tech shares. x.com  x.com 

Cybersecurity stocks' large run-up is at risk from a cheaper, open Chinese AI model. ValsAI reports that DeepSeek V4.1 Flash 1017 beat GPT 6 Sol on its offensive cybersecurity task; DeepSeek is far cheaper to run than a closed US model. x.com 

Fortinet could benefit if AI worms spread across unmanaged connected devices, increasing demand for agentless discovery and network segmentation. Endpoint agents cannot cover every camera or TV box, and perimeter firewalls miss traffic that stays inside the network; Fortinet's controls fit distributed sites. Anthropic's test on 15 Android TV boxes was slow and could not reliably complete replication, so this remains early. x.com 

Cybersecurity looks set to boom over the next few years as AI capabilities like Mythos keep advancing. Investors have moved from treating all software as bad to favoring companies that help, work with or combat AI agents. By their charts over the past month, Fortinet, CrowdStrike and Palo Alto Networks look like the group's big three, and Fortinet held up regardless of CrowdStrike's and Palo Alto's results. x.com 

Fortinet has topped because large language models will impair its business. x.com  x.com 

AI agents expand the enterprise attack surface, creating demand for cybersecurity and agent-aware defenses. The PHP2Shell vulnerability discovery underscored AI's role in finding and exploiting flaws; prompt injection, machine identities, model supply chains and data exfiltration add risks. Morgan Stanley called cybersecurity a major structural winner as model supply explodes. x.com 

Palo Alto Networks, CrowdStrike and Fortinet, the cybersecurity leaders, are long-term winners in AI and won't be displaced by it. Palo Alto is up 23% this year, CrowdStrike 20% and Fortinet 48%, and it is no coincidence that their CEOs have been buying stock. x.com 

CrowdStrike may distinguish itself from an expensive cybersecurity group by showing more breakneck growth at earnings next month. Fortinet's slowing product revenue exposed how much relentless execution investors had priced into the group's extreme multiples, pulling CrowdStrike down in sympathy. CrowdStrike remains in a higher tier than Fortinet, which itself ranks above SentinelOne. x.com  x.com 

Cybersecurity is the one software subsector where AI strengthens the story, because every AI gain arms both attackers and defenders, so spending only ratchets up. The market is forecast to grow from $189 billion in 2024 to $402 billion by 2034. Palo Alto sells consolidation: revenue grew 31% last quarter, and once customers platformize, switching costs become a fortress. Fortinet and Palo Alto rank first and second among software names in an 811-stock screen driven by institutional buying. x.com  … Show more
