Summary:
  • Israeli cybersecurity startup Guardio said Thursday it brought in $40 million, putting its valuation at $1.1 billion.
  • Investors included Assaf Rappaport, founder of cloud security firm Wiz, alongside ION Crossover Partners, Union Tech Ventures, Vintage Investment Partners, and others.
  • Founded in 2018, Guardio has raised $167 million to date and serves one million customers; its subscription offering that protects email and social media accounts generates annual recurring revenue of $150 million.

The raise and who backed it

Guardio said it secured $40 million to combat AI-fueled internet scams, a round that pegs the company at a $1.1 billion valuation. Assaf Rappaport, the Wiz founder, participated, joined by returning investors ION Crossover Partners, Union Tech Ventures, Vintage Investment Partners, and others.

The business in numbers

Since launching in 2018, the company has amassed $167 million across all funding. Guardio says its consumer security subscription protects digital accounts such as email and social profiles, now serving one million customers and producing annual recurring revenue of $150 million, which startups often use as a proxy for sales.

AI and the scam threat

CEO Amos Peled said scammers are leaning into AI tools to run smarter, larger campaigns. "The cost of attacking someone has collapsed while the quality and scale of the attacks have exploded," Peled said in an interview. "With 20 bucks and a Claude membership, you can create an amazing phishing flow, you can clone voices of your loved ones to implement the scams with unlimited scale."

What else investors are doing

Capital is flowing into AI-flavored security more broadly. In August, Alice - partnering with Anthropic PBC and with Alphabet Inc.'s Google and Nvidia Corp. - secured $140 million. Bloomberg reported this week that Upwind Security is raising $300 million at a $3.8 billion valuation. On Wednesday, HiddenLayer, based in Texas, finalized a $100 million financing round.

What this means for your portfolio

The takeaway is simple: attackers are getting cheaper AI tools, and defenders are getting fresh capital. Guardio sits at that intersection with scale, revenue, and a consumer focus. If you watch cybersecurity exposure in your holdings, note how fast money and momentum are gathering around AI-driven protection for everyday accounts.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • The most common mistake is treating the letter as an instruction. An A tells you a stock scores well for one goal, not that you should buy today.
  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

  • An asset puts money in your pocket and a liability takes money out, and the wealthy buy assets first, then let the assets pay for the fun stuff.
  • Before you buy anything, ask one question: does this put money in my pocket, or take money out of my pocket? Then you need a plan for the money you keep.

How to Build Your First $2,000 Emergency Fund and Wipe Out Every Debt Over 10%
  • Your first money goal isn't investing, it's $2,000 in its own account named Do Not Touch, built by moving 10% of every paycheck into it automatically.
