No Privacy.
No Freedom.
Governments broke their promise. We're here to hold them accountable.
Today, more than 80 governments use mercenary spyware to suppress and surveil civil society, breaking the social contract that underpins free democratic societies.
From journalists to innovators in decentralized technologies, no one is safe from government overreach.
Sentinel Alliance, born from the experiences of technologists targeted by mercenary spyware, unites victims, experts, and advocates to hold states accountable.
Because you could be next.
An invisible threat
Never in the history of humankind such a concentration of surveillance power has been concentrated in the hands of nation-states and corporations. It is a meta-threat that violates individual privacy and supresses the individual and collective foundational rights that define free societies.
Founded by victims
We're a collective of technologists who experienced government surveillance firsthand while building privacy tools and decentralized systems. Our founders include blockchain developers, cryptography researchers, and privacy advocates who were targeted for their work advancing digital freedom. Combined with seasoned legal experts and human rights defenders, we bring both technical depth and lived experience to the fight against surveillance overreach.
