AI can build the burglar's toolkit and sell the security guard a better alarm. The real question is: who gets paid?

Imagine paying a security guard to protect your house, only to discover that the company building increasingly intelligent burglars wants to buy a firm specialising in finding weaknesses in locks. Then your guard teams up with a rival burglar to improve security. 😅

Welcome to AI cybersecurity, where competitors collaborate, partners compete, and investors wonder whether they should buy the dip or duck for cover.

1. The plot twist: Friends today, rivals tomorrow

On October 13, 2026, The Information reported that OpenAI was in early talks to acquire Trail of Bits, a respected cybersecurity firm specialising in finding and fixing software vulnerabilities. No price was disclosed, and the discussions could collapse. This is a reported possibility, not a completed deal.

The companies had already collaborated on Patch the Planet, using OpenAI's coding capabilities and Trail of Bits engineers to identify vulnerabilities in open-source software.

Meanwhile, Anthropic launched its Cyber Mission on October 8, with CrowdStrike (CRWD) and Palo Alto Networks (PANW) among the founding partners of its Critical Infrastructure Defense Program.

Earlier, Anthropic's Project Glasswing brought together CrowdStrike, Palo Alto, Microsoft, Google, NVIDIA and other major organisations to use advanced AI for defensive security work. Anthropic reported that its Claude Mythos Preview model had identified thousands of high-severity vulnerabilities.

So, is AI replacing cybersecurity companies or helping them?

Both. And that is precisely where the investment opportunity—and the trap—lies.

2. AI's double-edged sword: The burglar gets smarter, too

AI can help defenders detect suspicious behaviour, investigate threats, identify vulnerabilities and accelerate software fixes.

Unfortunately, human attackers can use similar capabilities to automate reconnaissance, generate convincing phishing messages and discover weaknesses faster.

Advanced AI systems also create new security challenges when they can access files, applications, networks and external tools. That does not mean every AI system has malicious intent; it means poorly controlled systems can create real risks.

The result is a cybersecurity arms race.

More AI agents, software, application programming interfaces (APIs) and cloud workloads mean more potential entry points to protect. Yet AI can also make basic security tasks cheaper, putting pressure on vendors that sell little more than individual features.

The winning investment thesis is therefore not simply “more attacks equal more profits.”

It is more demand for security, combined with durable pricing power and improving cash flow.

3. The real game: Who controls the customer?

These are research candidates, not verified bargains. Without comparable current valuations and forward cash-flow estimates, a ranking by expected return would be false precision.

Why might established security platforms survive?

They offer more than a clever model. They can provide customer integration, historical threat data, access controls, incident-response workflows and tools to remediate problems.

But these advantages are not invincible. A partnership is not a moat, and proprietary data is not automatically valuable if competitors can obtain equivalent results.

The crucial question is whether customers continue paying for the platform when AI makes individual security tasks cheaper.

4. Frenemies are everywhere

This behaviour is not unique to cybersecurity.

• Microsoft and OpenAI: Microsoft has invested in OpenAI and distributed its models through Azure while developing its own AI capabilities. Cooperation does not eliminate competition.
• NVIDIA and cloud providers: AWS, Microsoft Azure and Google Cloud buy NVIDIA accelerators while developing their own chips. NVIDIA benefits from AI expansion even as customers seek alternatives.
• Microsoft Defender and CrowdStrike: Both compete in endpoint security, yet enterprises can use different products across identity, cloud and device protection.

The lesson is simple: companies can be suppliers, customers, partners and competitors simultaneously.

Investors should follow who controls distribution, customer relationships, data and pricing—not merely who appears in a partnership announcement.

5. Why the sell-off may—or may not—be an opportunity

Cybersecurity stocks fell after the Trail of Bits report renewed fears that AI developers could enter the security market more aggressively.

But another development complicates the story: on October 16, reports linked Palo Alto Networks' sharp decline to a vulnerability in its firewall platform that had been added to the US Cybersecurity and Infrastructure Security Agency's Known Exploited Vulnerabilities catalogue.

Do not attribute every decline to AI disruption. Company-specific security issues and broader technology-sector selling can also affect prices.

A falling stock is not necessarily a bargain. If its expected future cash flows decline faster than its share price, it may actually be more expensive relative to its prospects.

The bear case

Frontier AI providers could bundle vulnerability detection, automate investigations and undercut specialist vendors. Security companies might face lower prices, higher computing costs and greater research spending.

The industry could grow while some shareholders lose money.

The bull case

AI increases attack complexity and the need for protection. Established vendors integrate advanced models, automate more work and sell additional services. If revenue grows faster than delivery costs, their margins could improve.

The strongest businesses will demonstrate this through customer retention, paid adoption, pricing power and genuine free cash flow—not merely by putting “AI-powered” on every slide.

6. Your five-question investor checklist

Before buying a cybersecurity stock after a sharp decline, ask:

1. Who owns the workflow? Can the company detect, investigate, respond and remediate across multiple systems?
2. Is AI generating revenue? Look for paying customers and measurable adoption, not marketing language.
3. Who could replace it? Assess competition from OpenAI, Anthropic, Microsoft, Google and cloud providers.
4. Are fundamentals improving? Check recurring revenue growth, retention, operating margins and free cash flow after stock-based compensation.
5. What would invalidate the thesis? Identify evidence of customer losses, weaker pricing, deteriorating margins or excessive valuation.

For traders, wait for the initial emotional reaction to settle and identify the next meaningful catalyst. A bull put spread can define maximum contractual loss, but rising implied volatility, overnight gaps and unexpected disclosures still matter. Never sell options simply because the premium looks juicy. 🍖

For long-term investors, staged purchases may help manage timing risk, but they cannot rescue a broken thesis. A diversified basket may reduce company-specific exposure; it does not eliminate sector-wide risk.
