ARIN discontinues old SSL and TLS, now supports TLS 1.2 and 1.3

ARIN discontinues old SSL and TLS, now supports TLS 1.2 and 1.3 is profiled by BTW Media because published evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• ARIN has deprecated older SSL and TLS versions, now exclusively supporting TLS 1.2 and 1.3.
• This update enhances security and ensures stronger encryption for all ARIN services.

What happened: ARIN discontinues outdated SSL and TLS versions, supports only TLS 1.2 and 1.3

On February 4, 2025, ARIN announced that it has officially discontinued support for outdated Secure Socket Layer (SSL) and Transport Layer Security (TLS) protocols. Moving forward, ARIN will only support TLS versions 1.2 and 1.3 across all its services.

This change aligns with industry best practices for cybersecurity, reducing vulnerabilities associated with older encryption protocols. Users accessing ARIN services must ensure their systems and applications are compatible with TLS 1.2 or 1.3 to maintain uninterrupted access.

Why it’s important

Deprecating outdated encryption protocols is essential for maintaining a secure and resilient internet infrastructure. Older SSL and TLS versions are known to have security flaws that could expose users to cyber threats. By enforcing TLS 1.2 and 1.3, ARIN strengthens data protection and ensures compliance with modern security standards.

Organizations and individuals using ARIN services should update their systems to align with the new requirements, reducing the risk of security breaches and improving overall cybersecurity.
