Types of Scams We Help You Avoid
IsThisSpam protects you from the most common online threats. Learn what to watch out for.
Phishing Scams
Deceptive emails or texts pretending to be from trusted institutions like banks or government agencies. They trick you into sharing passwords, credentials, or multi-factor authentication (MFA) codes. Look for urgent language like "account suspended," generic greetings, and mismatched domain names in the sender's address or links.
Online Shopping
Fake e-commerce storefronts offering highly discounted popular items, electronics, or designer brands that never arrive. These sites often use brand names with slight variations or extra words (e.g., "discount-brand.com") and have no verified physical contact information. Check for missing HTTPS certificates, domain age less than 3 months, and payment terms that demand crypto, gift cards, or bank transfers.
Investment Scams
High-yield investment schemes, cryptocurrency giveaways, and "get-rich-quick" opportunities promoted on social media or direct messages. They promise high guaranteed returns with little to no risk, which is a key mathematical red flag. Scammers often pressure you to act immediately, request payment via untraceable digital assets, and show fabricated earnings dashboards.
Romance Scams
Scammers create fake online profiles on dating apps or social media, building deep emotional trust over weeks or months. Once trust is established, they fabricate urgent emergencies (e.g., medical crises, frozen bank accounts, or travel costs) to request wire transfers or gift cards. Key detection signals include requests to move communication off the original platform, refusal to video call, and stories that constantly change.
Tech Support
Deceptive pop-ups, search ads, or emails claiming your computer is infected with viruses, warning that your personal data is at risk. They instruct you to call a toll-free number where a "technician" asks to download remote-access software (like AnyDesk or TeamViewer) to fix the issue. Legitimate tech support departments will never contact you proactively via pop-ups to ask for remote access.
Delivery Scams
Fake package tracking notifications sent via SMS or email, mimicking postal services like USPS, DHL, or FedEx. They claim a parcel is held due to an incorrect address or unpaid customs fees, requesting a small fee and personal details to schedule redelivery. Spot these by checking the URL—official postal services do not use random domains (e.g., "usps-redelivery-fees.top").

Thank you for keeping my family safe"I have been using their services for over a year, and they are excellent for security. First, they offer fully offline options so you can choose your data usage AI models. They allow Ollama and cloud AI providers for their tools. I love that they catch phishing pages on every device, including iOS! Their UX has improved over the year and continues to get better. I have used their browser extensions across platforms, and they are a must-have for personal and business use. They have helped my family members spot scams! The company is responsive to issues when they arise and is very forward-thinking. Please keep up the hard work."
