We\u2019ll continue to support TLS 1.2 and 1.3 with their stronger cryptography.<\/p>\n<p>This move likely won&#8217;t come as a big surprise given that a number of technology companies including Apple, Microsoft, and <a href=\"https:\/\/www.mozilla.org\/en-US\/\" target=\"_blank\" rel=\"noopener\">Mozilla<\/a> have done likewise. Several prominent, security-minded industry groups have also previously mandated deprecation of the older TLS versions given the sensitivity of their data.<\/p>\n<p>For the very small fraction of B2 Cloud Storage customers who find themselves affected by this action, you&#8217;ll want to visit your web browser\u2019s advanced settings to make sure you\u2019re using a newer TLS version\u2014they all support TLS &gt; 1.2. And if you\u2019re transmitting data to the Backblaze Storage Cloud via one of our software integration partners, you\u2019ll want to make sure you\u2019re using the latest version of their software too because they also support newer TLS versions.<\/p>\n<p>This is one of those \u201csorry not sorry\u201d situations: we regret that this action will cause a brief inconvenience for a small subset of users, yet we know that this is the fundamentally right thing to do when the security of your precious data is paramount.<\/p>\n<p>Why now? Deprecation planning was already underway, but we opted to accelerate the timeline to better align with recent 2021 <a href=\"https:\/\/media.defense.gov\/2021\/Jan\/05\/2002560140\/-1\/-1\/0\/ELIMINATING_OBSOLETE_TLS_UOO197443-20.PDF\" target=\"_blank\" rel=\"noopener\">National Security Agency Cybersecurity Information<\/a> guidance.
