TL;DR
Let’s Encrypt has implemented a policy to block SSL/TLS certificates in US sanctioned territories. This change aims to comply with US sanctions but raises concerns about internet accessibility in affected regions. The policy is confirmed and currently in effect.
Let’s Encrypt has officially implemented a ban on issuing SSL/TLS certificates for domains located within US sanctioned territories, effective immediately. This move aims to ensure compliance with US sanctions laws and regulations, affecting websites and digital services operating in these regions.
The certificate authority (CA) announced the policy change via a published PDF document, stating that it will no longer issue or renew certificates for domains associated with US sanctioned regions, including Cuba, Iran, North Korea, Syria, and the Crimea region. This policy applies to all new certificate requests and renewals, effectively blocking secure connections for websites in these territories.
According to the official document, the decision aligns with US legal requirements and aims to prevent the facilitation of sanctions violations through encrypted communications. The policy is now in effect, and no exceptions are currently specified for existing certificates or other circumstances.
Impact on Internet Security and Access in Sanctioned Regions
This policy change could significantly affect internet security and accessibility in sanctioned territories by preventing the issuance of new SSL/TLS certificates, which are essential for secure online communication. Websites in these regions may experience disruptions, loss of HTTPS security, or total inaccessibility if they rely on certificates issued by Let’s Encrypt. This move underscores the increasing influence of US sanctions on global internet infrastructure and raises questions about the balance between compliance and digital rights.

US sanctions have historically targeted specific countries and regions, restricting financial transactions and certain types of internet activity. In recent years, US authorities have increased enforcement measures, including restrictions on the use of encryption and secure communications in sanctioned areas. Let’s Encrypt, as a major free CA, has previously aimed to provide open and accessible security, but now aligns its policies with US legal directives, reflecting broader industry trends toward compliance.
Prior to this, some CAs have voluntarily restricted services in sanctioned regions, but Let’s Encrypt’s explicit ban marks a notable shift towards stricter enforcement, potentially affecting millions of users and websites in these territories.
“We are committed to complying with applicable laws and regulations, including US sanctions, and have updated our policies accordingly.”
— Let’s Encrypt spokesperson
