Palo Alto Networks is stepping deeper into industrial security, teaming up with Siemens to debut a new cybersecurity suite targeting private 5G factory networks. Shares of Palo Alto climbed $4.68 during Thursday afternoon trading in the U.S.
Private 5G is catching on fast in factories loaded with sensors, robots, and autonomous gear — all tied into networks running entirely on-site, not through traditional carriers. Siemens flagged that a breach in these environments can bring production to a halt or even put workers at risk. On top of that, the EU’s NIS2 directive is clamping down on cybersecurity requirements in 18 key industries.
Siemens is packaging its private 5G hardware and SINEC Security Monitor—its site-level monitoring tool—together with Palo Alto’s next-gen firewall. That firewall looks at network traffic and industrial command flows. In a statement, Siemens said the combined system’s been tested in a range of factory scenarios and satisfies the IEC 62443 industrial cybersecurity standard. Crucially, Siemens claims there’s no impact on the low-latency connections that real-time production lines rely on.
“Manufacturers get secure 5G connectivity tailored to their operations without performance trade-offs,” said Michael Metzler, vice president for cybersecurity at Siemens Digital Industries, in the release. Dharminder Debisarun, who leads smart industries cybersecurity at Palo Alto, put it this way: the partnership aims to build the “central nervous system for the future of industry.” Siemens Press
The Siemens partnership builds on a string of announcements Palo Alto made earlier this week at Mobile World Congress. The company said it’s bringing Nokia, U Mobile, Aeris, and Celerway into its ecosystem to help secure so-called AI factories—the underlying data center and network infrastructure where AI models are trained and deployed. Anand Oswal, a Palo Alto executive, described the mission as safeguarding both the physical and digital layers.
Palo Alto is pushing for larger bundled contracts, responding to customers gravitating toward integrated platforms. On Tuesday, CrowdStrike projected fiscal 2027 revenue ahead of Wall Street’s expectations, citing strong demand for its AI-driven security offerings. Shares of both CrowdStrike and Zscaler climbed on Thursday.
Acquisitions have played a big part in the company’s expansion push. Last month, Palo Alto wrapped up its biggest buy ever—the $25 billion CyberArk deal. Back in February, it picked up Israeli startup Koi, and in November, it struck a deal for Chronosphere, part of a push to build out an identity, cloud monitoring, and AI platform.
The growth isn’t coming free. Last month, Palo Alto trimmed its fiscal 2026 adjusted profit forecast, blaming higher acquisition-related costs—though revenue expectations actually went up. Malik Ahmed Khan, an analyst at Morningstar, called the softer profit outlook “mostly due” to those deals, which Palo Alto now faces the challenge of folding in and pitching to its existing customer base.

Cybersecurity stocks saw gains, with CrowdStrike and Zscaler both rising during U.S. afternoon hours. Investors seemed to stick with bigger security names, undeterred by concerns over integration risks and stiffer competition.
