Security, Funded by Return on Security, is a weekly analysis of the public and private economic activity in the cybersecurity market. This week’s issue is brought to you by Anvilogic, Nagomi Security, and Mate Security.

Hey -

I hope you had a great weekend!

Another week and another sigh of relief mixed with a side of grief. Last week, NVIDIA held its quarterly earnings call and beat the “AI Bubble” charges against it for at least another quarter. While NVIDIA isn’t directly in the cybersecurity world, the current fate of all private and public money is at the whims of the world’s largest benefactor of the AI wave. NVIDIA's continued success means that every industry that has seen its boats rise (a rising tide lifts all boats), including cyber, can continue to march on strongly.

It wasn’t all rosy, though. All of that positive news was offset by continued high inflation and low job market data in the US, leading the U.S. Federal Reserve and my boy JPow to be split on an interest rate cut in December.

It’s always the “expectations” that drive our markets, and about what people and investors anticipate. When you’ve been living in a “stocks only go up and to the right” environment for so long, any apparent cracks in the foundation make every freakout, and that’s exactly what we saw last week.

Cyber, though, just like Wu-Tang, is here forever (and is for the children). Bubble or no bubble, strong economy or not, someone still has to secure the proverbial bag.

It was also great to meet up with some friends, old and new, in London, stylishly wearing our AI-generated black-tie attire.

If you’re celebrating Thanksgiving this year, I hope you tack on some real mass and enjoy some time off with your friends and family! 🦃

Last issue’s vibe check:
Anthropic published a report on catching threat actors using AI for 'mostly autonomous' attacks. How do you feel about it?
🟩🟩🟩🟩🟩🟩 Attackers do a lot of automation already
🟨⬜️⬜️⬜️⬜️⬜️ Valuable threat intelligence
🟨⬜️⬜️⬜️⬜️⬜️ Interested but want third-party validation
🟨🟨🟨🟨🟨⬜️ Can't tell where the research ends and the sales pitch begins
🟨🟨🟨⬜️⬜️⬜️ Skeptical until I see technical evidence

If you looked anywhere on social media last week, you would have seen person after person sharing the Anthropic report and their take on what happened. You’d see typical responses from people trying to talk their own books, saying things like, “This is why the world needs our AI-driven autonomous whiz-bang platform at Vendor X.

But it seems like a lot of the security community kind of scratched their heads over the report. It was both interesting and I’m really glad they shared it, but it left us with many more questions than answers. It was billed as a threat intel report, but it left far too much to the imagination.

My friend Matt Johansen breaks it down really well here.

Some of the top comments from last week’s vibe check:

💬 “Given that previous claim by MIT business school that 80% of ransomware actors used generative AI used data from before 2022, I'm gonna need strong sources. Also a definition of ‘autonomous’”

💬 “Automation is cool and so is Claude, but Anthropic strayed over the line, overselling the amount that AI did here.”

📸 YoY Snapshot

Rolling 13-week charts that compare funding and acquisitions weekly in a year-over-year (YoY) view between 2024 and 2025.

Funding continues to surge, with over 190 deals in the last 13 weeks totaling $3.7B and averaging $24.1M per deal.

M&A activity continued with 85 acquisitions over the past 12 weeks, up 10% from 77 last year. There’s also an interesting trend emerging of cybersecurity companies acquiring non-cybersecurity companies. We saw that last week with Palo Alto, but it’s happening on the smaller end of the scale as well.

☎️ Earnings Reports

This analysis is personal research and opinions only. This is not financial or investing advice. Do your own due diligence before making investment decisions.

Earnings reports from last week: $PANW ( ▲ 1.29% )

A huge earnings call for Palo Alto last week! ARR was up nearly 30% to $5.85 billion, and total revenue was up 16% to $2.47 billion. There was also strong product traction, with over 450 XSIAM (Palo’s visibility and automation platform) customers at $1 million ARR (!!) and SASE ARR growing 34%.

The biggest news of the call was the announcement of an acquisition into a new market segment by acquiring an observability company, Chronosphere, to the tune of $3.35 billion. With a reported ARR of $160 million, this marks the second acquisition in a row of buying mature players with clear market dominance in their space.

Nikesh (probably)

While this wasn’t a cyber acquisition, it takes direct aim at what Splunk and Cisco have going on and is a clear run at the enterprise data fabric layer. To me, this acquisition makes a lot of sense, as security monitoring and observability have been slowly converging over the last five years.

Palo Alto raised its forward-looking guidance for the full year and approved an extension of the current common stock repurchase authorization of $1 billion. Analysts were rightfully cautious yet optimistic, given the many moving parts for Palo Alto to deliver on. The only thing left to do now is to sit back and let Nikesh cook.
