What Guardio does
Guardio is an Israel-headquartered cybersecurity company founded in 2018 that builds AI-driven protection products primarily for consumers and small businesses, with a growing footprint serving AI platform operators. The company is best known for its browser extension and mobile applications, which are distributed through the Chrome Web Store (600,000+ users, 4.5-star rating), Microsoft Edge Add-ons, Google Play, and the Apple App Store. Underlying the product is a cloud-centric architecture that combines machine learning, behavioral heuristics, and proprietary client-side deep learning models to deliver real-time verdict latencies of 10-30ms, while a dedicated Guardio Research Team maps the Chrome Extension ecosystem and continuously probes the visible internet to surface criminal infrastructure.
The commercial offering spans tiered personal subscription plans (Individual, Duo, Family) priced $4.67-$9.99 per member per month on annual billing, a per-seat Business/Teams plan with admin dashboard and breach monitoring, a VIP support add-on, and identity theft insurance and restoration services. The company's go-to-market is primarily product-led growth via the freemium browser extension, supplemented by app marketplace listings, an enterprise field sales motion for teams, and an OEM/API motion through Guardio Safe Browsing for AI, which delivers real-time threat detection to AI browsers, agents, and generative platforms. A documented integration with Lovable (November 2025) demonstrates this OEM route into AI-era web infrastructure.
Guardio is venture-backed with approximately $127 million raised across a $47 million Series A led by Tiger Global (December 2021) and an $80 million Series B led by ION Crossover Partners (November 2025). The company reports 500,000 paying users and $100 million in annual recurring revenue as of 2025, with over 1.5 million people protected across devices, and operations primarily based in Tel Aviv with a US-skewed customer base and announced US expansion plans.

Guardio competitors and assessment
Company assessmentDirect peers
- Malwarebytes: Malwarebytes provides consumer and small business cybersecurity with a strong focus on browser-based and endpoint protection against phishing, scams, and malicious sites. Its product breadth and target customer closely mirror Guardio's browser extension + mobile + per-seat business model.
- Aura: Aura is a fast-growing consumer digital security and identity protection platform combining VPN, antivirus, password manager, and identity theft protection in a subscription bundle. It targets the same individual and family buyer as Guardio and has scaled aggressively via direct-to-consumer marketing.
- TotalAV: TotalAV is a consumer cybersecurity suite focused on antivirus, web shield, and phishing protection marketed aggressively through affiliate and direct-to-consumer channels. Its freemium-led acquisition and web threat focus parallel Guardio's PLG motion and core browser protection capabilities.
- Surfshark (Nord Security): Surfshark, part of Nord Security, has expanded from VPN into a broader consumer security suite including antivirus, data breach alerts, and identity protection. Its bundling of privacy and security at consumer subscription price points puts it in direct competition with Guardio's individual/family plans.
Broad incumbents
- Norton (Gen Digital): Norton/Gen Digital is a leading incumbent in consumer cybersecurity and identity protection, offering bundled antivirus, phishing protection, VPN, and identity theft services. It competes directly with Guardio in the consumer subscription tier but operates across a much broader portfolio including LifeLock identity services.
- McAfee: McAfee is a long-standing consumer cybersecurity incumbent offering antivirus, web protection, identity monitoring, and VPN. Its consumer subscription model and web/email phishing protection features overlap directly with Guardio's Individual/Family plans and browsing protection capabilities.
- Avast (Gen Digital): Avast is a major freemium consumer antivirus and online security provider now under Gen Digital. Its free-tier-led acquisition motion, browser protection, and phishing/scam blocking features are directly comparable to Guardio's PLG-driven distribution and core functionality.
- Bitdefender: Bitdefender offers consumer and SMB cybersecurity including antivirus, anti-phishing, and web protection, with strong independent lab scores. Its consumer Digital Identity Protection and Fraud Detection offerings overlap with Guardio's identity and data leak alert features.
Emerging players
- SlashNext: SlashNext specializes in AI-driven phishing and BEC detection across email, browsers, and messaging channels, with a strong enterprise/API go-to-market. Its AI-first approach to phishing and scam detection closely parallels Guardio's machine learning architecture, though it primarily serves enterprise rather than consumers.
- Bolster: Bolster provides AI-powered phishing, scam, and brand impersonation detection using computer vision and large language models. Its technology stack and threat focus are highly comparable to Guardio's deep learning-based visual detection, though Bolster is enterprise-focused rather than consumer-led.
