Jamie Dimon has steered the world's largest investment bank, JPMorgan Chase, through several major economic shocks over the last 20 years.
However, he believes cyber threats powered by artificial intelligence (AI) are one of the biggest risks to his bank today.
Cybersecurity stocks like SentinelOne could be big winners over the long term if other chief executives have the same concerns as Dimon.
With a market capitalization of almost $900 billion, JPMorgan Chase (NYSE: JPM) is the world's largest investment bank by a wide margin. Chief executive officer Jamie Dimon has been at the helm for over 20 years, successfully steering the bank through the global financial crisis, the European debt crisis, the COVID-19 pandemic, and many other economic shocks.
In a letter to shareholders released in April, Dimon named cyber risk as one of the biggest threats to JPMorgan, primarily because artificial intelligence (AI) is laying the foundation for increasingly sophisticated attacks. He reiterated his stance in an interview with Bloomberg last Tuesday but said cyber risk has increased tenfold since his letter, following the release of Anthropic's Mythos AI models, which can autonomously uncover vulnerabilities in any corporate network.

Cybersecurity stocks are soaring this year as investors price in much higher demand. SentinelOne (NYSE: S) developed a holistic AI-powered platform called Singularity, which protects enterprises from top to bottom. Its stock is still one of the cheapest in the industry.
Here's why it could be a great buy as the cybersecurity industry tackles the AI threat.

AI can be a powerful tool for enterprises, helping improve productivity, but it also creates new attack surfaces. Every time businesses deploy chatbots, agents, or other applications, they leave their sensitive internal data and valuable digital assets exposed to cyber threats, underscoring the importance of modern cybersecurity.
SentinelOne's Singularity platform protects cloud networks, employee identities, endpoints (computers and devices), and everything in between. Its priority is to prevent breaches, but it also includes several remediation tools to help enterprises restore their digital infrastructure in the event of a successful attack, thereby minimizing downtime. Singularity also features a built-in AI assistant called Purple AI, which uses advanced reasoning to autonomously investigate threats and take action when necessary.
SentinelOne has developed a portfolio of new tools specifically designed to protect enterprises during AI deployments. Prompt Security, for example, defends against a new technique called prompt injection, where hackers try to trick chatbots and agents into handing over sensitive data by disguising their malicious requests as legitimate commands. Prompt Security also logs every AI application used internally, so it immediately knows if an unauthorized app is circulating on the corporate network.
SentinelOne saw $1.2 billion in annual recurring revenue (ARR) at the end of its fiscal 2027 second quarter (which concluded on July 31), a 22% increase from the year-ago period. However, the ARR attributed to its AI products, such as Prompt Security and Purple AI, almost tripled, indicating that customers are clearly investing heavily in next-generation protection.
A notable portion of that growth appears to have been organic, because SentinelOne actually decreased its sales and marketing spending during the second quarter. In other words, it seems customers were actively seeking AI-related protection, which bodes well for demand going forward.
Although SentinelOne trimmed its marketing costs in the second quarter, it ramped up its research and development spending by 27% to fund its innovation pipeline. As a result, its operating costs increased overall, leading to a generally accepted accounting principles (GAAP) net loss of $93.4 million.
Shareholders might be willing to endure SentinelOne's losses as long as they are paying off in the form of blistering fast AI-related revenue growth. But profits will have to follow in the future, or the company might have to raise more money through debt or equity financing, which could be a headwind for investors' returns.
SentinelOne stock is trading at a price-to-sales (P/S) ratio of 7.7 as I write this (Oct. 7), making it significantly cheaper than its rivals Palo Alto Networks and CrowdStrike, which have P/S ratios of 26.8 and 50.5, respectively.

Both Palo Alto and CrowdStrike generate significantly more revenue than SentinelOne, so they have a much bigger market share. And CrowdStrike specifically is growing faster; its ARR jumped 25% to $5.8 billion in its most recent quarter. As a result, these vendors deserve to trade at premium valuations.
However, I would argue that the valuation gap is currently too wide, given the momentum in SentinelOne's AI product portfolio. I'm not suggesting it will ever match the valuations of Palo Alto or CrowdStrike, but there is certainly some room for upside.
After all, Jamie Dimon is definitely not the only CEO of a major company making cybersecurity a top priority right now. AI-related threats could force every public and private organization to spend more on protection in the coming years, making this the biggest opportunity in SentinelOne's history.
