The SEL-3620 is a router, virtual private network (VPN) endpoint, and firewall device that can perform security proxy services for serial and Ethernet-based intelligent electronic devices (IEDs). The SEL-3620 helps create a user audit trail through strong, centralized, user-based authentication and authorization to modern and legacy IEDs. The SEL-3620 secures your control system communications with a stateful deny-by-default firewall, strong cryptographic protocols, and logs for system awareness. The SEL-3620 also manages protected IED passwords, ensuring that passwords are changed regularly and conform to complexity rules for stronger security. The integrated security proxy also provides user-based single sign-on access to Ethernet and serial devices.
