Cybersecurity AI risks

There has been a massive debate this week over the safety of modern AI tools. Examples have been growing of the ability to use agents and models from the likes of Anthropic and others to target vulnerabilities for hacking.

This has been a boon to cybersecurity stocks like Rubrik. Rubrik is a defense layer that protects your back-up systems, ensuring your data remains secure in the event of an attack. As cyber risks grow, the theory is that more and more organizations will turn to Rubrik to secure their data.

Its business model is to sell subscriptions that grow in price the more data is protected, a great business model because the amount of data held by enterprises is growing every year. Last quarter, Rubrik's annual recurring revenue (ARR) grew 33% year-over-year to $1.66 billion, with gross margins of nearly 80%.

Is Rubrik stock a buy?

After going up this week and soaring close to 200% in the last five years, Rubrik stock now looks expensive with a price-to-sales ratio (P/S) of 13.7. However, this booming demand for cybersecurity services may lead to durable revenue growth over the next decade, which could bring down Rubrik's valuation rather quickly.

If you are looking for a cyber stock to bet on, Rubrik could be a good pick for your portfolio.
