Say what is actually live
A feature that is built but switched off is labelled as paused or coming soon, on the pricing page and everywhere else. We would rather lose a sign-up than describe something that does not run yet.
About
A security toolbox for everyday people
MyDefense is built in Istanbul, Türkiye. It started as one idea and became a set of small, independent tools that answer everyday questions: is this message a scam, is this link safe, has this password leaked.
Most security advice is written for companies. Most of the problems people actually meet are small and sudden: a text about a parcel, a link in a WhatsApp group, a bank message that does not feel right. Those need a quick, plain answer, not a product tour.
We began with a different idea: finding and deleting your personal data across social platforms. That work depends on approval from each platform, and it is paused while those approvals are pending. Along the way we kept building the pieces people kept needing, and each one turned out to be useful on its own. That is how a single product became a toolbox.
Today that means free checks for messages, links, passwords, photos and websites, a browser extension and a Telegram bot, deeper services behind a free account, the MyDefense Academy for learning, and erasure requests under KVKK and other privacy laws. New services will be added one at a time, each with its own switch, under the same account and wallet.
We are early, and we would rather be plain about it. Our services are free for everyone. Anything built but not switched on is labelled as such on the page, not in a footnote.
Principles
Three rules we hold ourselves to
These are the ones we would notice breaking.
Hold as little as possible
Password, photo and Paste Guard checks run in your browser and send us nothing. A saved report keeps the findings, not the message you checked, and you can export your data or delete your account in Settings.
Use the law and plain checks, not tricks
Our website checks are passive: nothing is attacked or probed. Where someone else holds your data, we prepare the erasure request your own law entitles you to, rather than automating against platforms.
Talk to us
Questions about how something works, a tool you would like to see, or a data request: write to us and a person reads it.
Try one tool
The fastest way to judge whether this is worth your time is to use one.
