A read-only status string reporting whether the Contivity's IPsec failover service, which preserves VPN tunnels across a gateway switchover, is Disabled, Healthy, or in Alert. For a VPN gateway pair configured for high availability, this tells the admin whether existing IPsec sessions would actually survive a failover event rather than being dropped and requiring re-negotiation. Before relying on a planned maintenance failover, an admin would check that ipsecFailoverStatus reads Healthy so that active remote-access tunnels don't get torn down during the switch.
