The 20-year-old service is planned for retirement on April 30, 2021, past which Accellion won’t renew licenses for the software.

FTA runs on CentOS 6, an operating system that reached end-of-life on November 30, 2020, a matter that Accellion brought to the attention of FTA customers six months ago.

Despite efforts to completely move away from FTA, however, Accellion still had approximately 50 customers using the product back in December 2020, when a critical vulnerability was identified in it.
