The world of investigation has long since entered the digital age. Online scams, cyberattacks, fake transfer fraud… crime now knows no boundaries. In response, in 2021 France equipped itself with a discreet but formidable tool: ANTENJ, the National Agency for Digital Judicial Investigation Techniques. By 2025, this structure had become indispensable.
2013: PNIJ, the first step towards ANTENJ
It all began in 2013 with the launch of PNIJ (the National Platform for Judicial Interceptions). This platform centralizes telephone tapping and communications interceptions. However, with the explosion in digital usage, this system quickly became insufficient.
2021: birth of the ANTENJ
In March 2021, the ANTENJ was officially created. Its mission: to provide judges, police officers, and gendarmes with investigative tools adapted to the digital world. With teams of engineers and cybersecurity specialists, it has become the equivalent of a “high-tech laboratory” for the justice system.
2017: the “WannaCry” case as a wake-up call
In May 2017, the “WannaCry” ransomware paralyzed thousands of computers around the world, including in France. Hospitals and businesses found themselves blocked. This episode, followed in June 2017 by the “NotPetya” attack, highlighted the vulnerability of digital infrastructures and convinced the French authorities to speed up the creation of a dedicated agency.
2023: the EncroChat case, the triumph of digital justice
In 2023, ANTENJ plays a key role in exploiting data from the encrypted EncroChat network, used by drug traffickers and criminal networks. Millions of encrypted messages are decrypted, leading to the arrest of hundreds of suspects in France and Europe. This example illustrates the power of digital techniques when used in the service of justice.
2025: an increased budget and a strategic role
In January 2025, the ANTENJ’s budget reached €54.7 million. The agency now works closely with the gendarmerie, the national police, and specialized magistrates. Its role has become central to the fight against terrorism, organized cybercrime, and large-scale fraud.
Private detective: what place in this landscape?
For a private detective, the existence of ANTENJ is a game changer. Even if access to the agency’s institutional resources is reserved for the justice system, a private detective must understand these developments in order to remain relevant. In cases involving online defamation, cyberbullying, or unfair competition, private investigators already exploit legally accessible digital traces: public posts, technical evidence, and analysis of digital behavior.
The EncroChat case served as a reminder that digital technology can bring down even the most organized networks. Similarly, a modern private detective must be able to combine traditional fieldwork with digital skills. At Agora Détectives, we see every day that this hybridization is now essential.
A silent revolution
In the space of a few years, France has gone from scattered tools to a truly specialized agency capable of tracking criminals on servers on the other side of the world. ANTENJ is not known to the general public, but it is already writing the judicial history of tomorrow. And for any private detective, it serves as a reminder: today’s investigations take place as much on the streets as in cyberspace.
