Aggressive marketing, including fake countdown timers and paid YouTube sponsorships, has also been criticized for pressuring users into quick decisions.

Sneaky Billing & Subscription Issues: Many users report being charged unexpectedly after signing up for a “free trial.” Guardio requires a credit card upfront, and some users claim they were unaware of automatic billing. Some users have even reported unauthorized charges flagged as fraud by their banks.

4. Privacy Concerns & Data Collection: Guardio’s data practices have raised eyebrows.

While there’s no concrete evidence of wrongdoing, these concerns have not been adequately addressed by the company.
5. Poor User Experience & Reputation: Constant pop-ups and fear-driven messaging have frustrated many users. Some feel that Guardio creates stress rather than offering real protection. Guardio’s reliance on paid YouTube sponsorships has also damaged its reputation, with many users doubting the sincerity of influencer endorsements.

7. Performance Impact: While Guardio is designed to be lightweight, some users note a slight performance impact, especially when multiple tabs or extensions are running.
8. Lack of Mobile App: Some users express a desire for a mobile app to extend Guardio’s protection to their phones.
9. Customer Support Responsiveness: A few users feel that customer support is unresponsive or unhelpful, particularly when dealing with subscription issues.

Final Verdict: Is Guardio a Scam or a Trusted Security Tool?

Guardio is not a scam; It is a legitimate browser-based security tool that provides real-time protection against phishing, malware, and data breaches, backed by $47 million in funding and 1.5 million users.

It complies with GDPR and Google API policies, but users have reported aggressive marketing tactics, false security alerts, and billing issues, including unexpected charges and difficult cancellations. 

Guardio only protects Chrome, Edge, and Opera browsers, lacks full-device security, and has privacy concerns due to its ties to Meta (Facebook). 

While it offers identity theft insurance and email protection (Gmail only), alternatives like Bitdefender, Norton, or Malwarebytes provide more comprehensive security. 

Guardio is not a scam. But you should review its features and billing practices carefully before subscribing
