Hackers are putting AI to work, and security budgets are following. Companies need defenses built for faster, harder-to-spot attacks, pushing cybersecurity spending beyond routine upgrades. That puts the biggest vendors in position to turn the AI threat into years of new spending.

Machine-speed pressure: Palo Alto Networks is becoming the clearest public-market test of that shift. The company expects fiscal 2027 revenue to grow 23% to 24% as customers replace fragmented security tools with platforms that can respond faster to AI-driven threats. CEO Nikesh Arora warned that “if your fragmented products don’t talk to each other, then AI is going to get the better of you” because cyber infrastructure must respond at “AI-level or machine-level speed” as customers modernize.

  • Palo Alto reported fourth-quarter revenue of $3.41B, beating FactSet’s estimate as demand for its security platforms remained strong.
  • Next-generation security annual recurring revenue surged 63% year over year to $9.1B, showing customers are shifting spending toward newer products.

Cybersecurity’s AI Boom Spreads Out

AI is creating opportunities across more of the cybersecurity market, from endpoint security and data recovery to vulnerability management and identity. Vendors are also using the technology to build faster defenses of their own. Nvidia and CrowdStrike recently introduced SafeMind, a family of agentic AI models that can find attack paths and help close them inside CrowdStrike’s Falcon platform.

  • CrowdStrike said AI-enabled adversaries jumped 89% in 2025, helping drive cybersecurity spending toward a projected $300B by 2029.
  • That demand is spreading across the sector, pushing Rubrik’s annual recurring subscription revenue 32% higher and helping Commvault Systems lift revenue 19%.

The investment case: As Nvidia's CEO Jensen Huang put it, “Instead of what everybody talks about, which is using AI to exploit companies, we’re going to use AI to defend companies.” Arora sees plenty of work ahead, estimating that companies have roughly $1T of “global cybersecurity debt” tied to aging systems. With those upgrades likely to happen over several years, investors should focus on vendors already showing stronger revenue, platform adoption, and cash generation.
