Fortinet's valuation leaves it vulnerable to a sharp drop: it trades above 53x next-twelve-month earnings despite EPS growth below 20%. Its post-earnings tumble illustrates that risk. x.comÂ
Fortinet's recurring service growth is slowing while its firewall product refresh does the heavy lifting. Service revenue grew 13% versus 37% for products, and the full-year service guide was cut to $5.15-$5.17 billion. A cut to the recurring guide rarely gets bought back in a week; this looks like the start of a rerating lower. x.comÂ
Fortinet has a possible catalyst in Pace the Frontier, which could lift cybersecurity broadly. On the chart, the stock has reclaimed its pivot while still in a boring consolidation. x.comÂ
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.comÂ
Fortinet looks expensive at 48x cash earnings and 40x next year's, versus about 30x for software companies. Fair value is $116-$148, roughly 30x next year's cash earnings give or take 12%, so the stock trades 19% above the top of fair and turns expensive above $196. This is a valuation screen based on reported earnings and revenue estimates, with no deeper fundamental work. x.comÂ
Fortinet is a beautiful business because recurring security subscriptions make it highly stable and cash-generative. It is the clear leader in firewalls, protecting over 800,000 clients with fast, energy-efficient tools built on its own custom chips. x.comÂ
Tenable looks cheap among cybersecurity software names, trading at a lower P/E than Palo Alto Networks and CrowdStrike, a lower forward P/E than Fortinet, and one of the group's lowest PEG ratios. Its chart shows a double breakout from a triangle and range highs, with low cycles and confirming on-balance volume. x.comÂ
Palo Alto Networks is the most overvalued cybersecurity stock by a mile, at about 25x forward revenue while growing only 15% organically. Anything above 10x revenue is hard to justify, let alone 20x. Worse, the "Mythos moment" that sent cyber valuations vertical has not yet shown up in its results. x.com x.comÂ
Fortinet's strength should beget strength after a blowout Q2 and raised guidance. Revenue rose 26% to $2.05B versus $1.89B expected, EPS rose 41% and product revenue 52%, with billings up 33%. Q3 and full-year 2026 guidance both topped estimates, with full-year revenue at $8.02-8.18B. Management credits demand for its integrated SASE firewall on a single operating system and custom ASIC. IBM's profit warning flagged clients distracted by cybersecurity concerns, a sector catalyst. x.comÂ
Palo Alto Networks wants every AI agent's credentials routed through it, and whoever brokers the keys sits inline on every action a CISO wants to control. It is the only firewall vendor that also owns a top privileged-access stack. Last quarter revenue grew 34% at a 70% gross margin, with $4.11 billion of free cash flow and net cash. The price is steep at 81.2x forward earnings and 28.2x sales, leaving no cushion if cloud platforms credential agents natively. x.comÂ
