Let's Encrypt Issues Three Billionth Certificate

The non-profit that runs Let’s Encrypt has revealed the open certificate authority (CA) passed the three billion mark for certificates issued this autumn, making the internet a safer place in the process. However, in the past, security experts have also noted that threat actors used Let’s Encrypt-issued certificates to hide their own malfeasance and legitimize phishing sites. According to a new report from the Internet Security Research Group (ISRG), the non-profit behind Let’s Encrypt, usage grew by more than 33 million domains in 2022.
