The Cisco team is actively monitoring the situation with our cloud service provider and will restore the service as quickly as possible. In the meantime, please be aware of the following impacts: • Emails will not be scanned by SETD, which may increase exposure to phishing, malware, and other threats. Access to the SETD portal is unavailable for reviewing threat reports, managing configurations, or accessing quarantined emails. • There may be a delay in threat detection and response until the service is restored. • A backlog of unscanned emails may occur and require additional processing once service resumes. We apologize for any inconvenience this may cause and appreciate your understanding. If you have any questions or concerns, please contact our support team.
