Return SSL-VPN users and IPsec tunnel status in one concise view.
AI agents call fortigate_get_vpn_overview to retrieve information from Fortigate MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
