ABOUT THE PRODUCT AND TEAM

We built TG Cerber because we know what losing access costs

TG Cerber is built by entrepreneurs and engineers who have relied on Telegram for years as business infrastructure — contacts, channels, agreements and access.

Why we built it

Three of us have lost a Telegram account, or come close to it. Each time it looked different — and that is exactly why, taken together, they point to one conclusion.

  1. 1

    He never opened the list

    In May 2025 Fedor lost an account holding ten years of work: thousands of chats, contacts, access credentials and agreements that existed nowhere else. The intruder's session had been sitting in his settings the whole time, one button away from being removed. He simply never opened that screen — as almost nobody does. The account was never recovered, and the hardest part was not technical: it was proving to people that he was himself again.

  2. 2

    He opened it and saw it

    Dmitriy checks his list of active sessions more often than almost anyone. He saw an unfamiliar device there, found an explanation for it, and did not terminate the session. The account was lost anyway. Someone who notices a discrepancy tends to explain it rather than close it.

  3. 3

    There was nothing to notice

    Fazil was targeted by a sophisticated social-engineering attempt: a cloned profile of a partner at a well-known fund, weeks of conversation, a call with an "analyst", and a document that asked him to run a terminal command to open it. The profile was checked on LinkedIn and looked genuine. No amount of vigilance would have helped here: at the moment the decision is made, nothing looks wrong.

Manual vigilance does not scale. It fails when nobody opens the settings. It fails when someone does open them and explains away what they see. And it fails when the request comes from someone you trust. That is why TG Cerber watches the session list for you and never leaves an unconfirmed login without a response.

How we work

  • Product promises are kept separate from hypotheses and from what is still preparing for launch.
  • We name Telegram's limitations directly instead of writing around them.
  • TG Cerber Lab publishes its method, its data and its limitations, including negative results.
  • The boundaries of security and privacy are described in the Trust Center.
