Guardio said on Sept. 3, 2026, that it raised $40 million at a $1.1 billion valuation after crossing 1 million paying customers and more than $150 million in annual recurring revenue. The company announced the financing in a post on X and a statement.
The paying-customer count was about half as large a year earlier, CEO and co-founder Amos Peled wrote in a company blog post. Guardio also said its revenue grew more than 100% year over year for four consecutive years. The valuation puts its consumer scam-protection business above $1 billion.
Existing investors ION Crossover Partners, Union Tech Ventures, Vintage Investment Partners, Cerca Partners and Emerge Ventures led the round, according to CTech. Wiz co-founder and CEO Assaf Rappaport also invested. The financing brought Guardio’s total funding to $167 million since its founding in 2018, Bloomberg reported.
Guardio said its software monitors messages, email, calls and web activity to stop scams before users open a link. It is intended to detect attacks that move between devices, including a scam that starts with a phone call and leads to a later computer download.
Peled said attackers increasingly target people rather than computers and that artificial intelligence has made scam operations cheaper to run. He said consumer security should focus on the individual instead of a single device.
Peled founded Guardio with Michael Vainshtein, its chief technology officer, and Daniel Sirota, its chief architect. The three had worked together for a decade before starting the company, Peled wrote. Guardio took no outside money during its first three years, then raised $47 million in its first outside financing in December 2021.
The company said it will use the new capital to expand its consumer-protection products. Peled described the round as a step toward reaching tens of millions of people who still rely on older security software.
