Rapid advancement of information technology elevates the risk of cracking of digital signatures. In order to protect our client's interests, SGS TW will renew digital signatures on a timely basis to avoid forgery. We used to have four digital signatures (2007/08/22, 2009/08/20, 2011/0818 and 2017/07/20) issued by VeriSign and DigiCert (2020/08/17) under the title of SGS TW. The most up to date is issued by DigiCert on Jun 19, 2023.
