Company intelligence
As of September 3, 2026, Guardio was last valued at $1.1B (September 2026 Series B).
Guardio sells consumer cybersecurity; it announced a $1.1B valuation in September 2026 after a $40M round and says it has $150M ARR.
Guardio sells consumer cybersecurity subscriptions. It started as a browser extension that monitors malicious sites and alerts users to data leaks. It has since added phishing protection and built mobile apps that offer identity management, spam filtering and scam protection.[1]
Guardio says it protects the person rather than the device, monitoring messages, email, calls and web activity to stop a scam before the victim opens the link. The homepage offers personal and business plans.[2],[3]
Guardio reports these usage figures on its own about page. It says 1.5M people are protected across logins, devices and everyday online activity. It says its research team intercepts 825K threats daily and that 320K malicious sites are blocked each day. These are company claims and are not independently verified.[4]
Guardio said in November 2025 that it is building a tool for code and websites made with vibe-coding tools. TechCrunch reported that the company is using its experience with extensions and apps that scan for malicious and phishing sites to look for artifacts of malicious code written with those tools. It also added features that show users which documents they have shared publicly and which accounts lack multi-factor authentication.[1]
Guardio was founded in 2018 in Tel Aviv and was bootstrapped until its first outside round in December 2021. The founders are Amos Peled, Michael Vainshtein and Daniel Sirota.[5],[1]
Guardio was the three founders' second startup together. TechCrunch reported in 2021 that their first company, Arpeely, specializes in real-time media auctions using machine and deep learning.[5]
In December 2021 Guardio had 1 million users of its freemium browser extension, and Peled said about 100,000 were paying. Those paying users were a mix of consumers and very small businesses, and the company planned to keep the U.S. as its main market.[5]
By November 2025 Guardio said it had 500,000 paying users and claimed it reached $100 million in annual recurring revenue that year.[1]
Guardio announced its first outside funding in December 2021: $47M led by Tiger Global. Emerge, Vintage, Cerca Partners, Union and Samsung Next also participated.[5]
In November 2025 Guardio raised $80M in a round led by ION Crossover Partners. Existing backers Union Tech Ventures, Vintage Investment Partners and Emerge also invested. Guardio did not disclose its valuation but said it had tripled since the $47M round led by Tiger Global in 2021, and it said it did not consider itself a unicorn.[1]
On September 3, 2026, Guardio said it had reached a valuation of $1.1 billion. The release ties the valuation to a $40M round that included Wiz co-founder and CEO Assaf Rappaport, along with existing investors ION Crossover Partners, Union Tech Ventures, Vintage Investment Partners, Cerca Partners and Emerge Ventures, and puts Guardio's total funding at $167M. The release does not name a lead investor or label the round a Series B or any other series.[2]
The same release says Guardio has grown revenue more than 100% year over year for four consecutive years, reaching one million paying customers and $150M in ARR. These are company-reported figures. Guardio is private and has published no audited revenue.[2]
Guardio sells mainly to consumers. Its homepage says over 1.5M people stay safe online with Guardio, while the September 2026 release counts one million paying customers. The two figures measure different things.[3],[2]
Guardio announced a partnership with Lovable in November 2025 to scan websites made on Lovable's platform for threats to users. TechCrunch reported that the deal came after a report highlighted that several sites built on Lovable had serious security holes. Michael Vainshtein said few AI tools partner with a security company to secure content generated on their platforms.[1]
