A final patch to address the vulnerability will be available in early May 2021.\r\n    Pulse Secure has been working closely with Mandiant, affected customers, government partners, and other forensic experts to address these issues.\r\n    There is no indication the identified backdoors were introduced through a supply chain compromise of the company\u2019s network or software deployment process.",
