+# -Wireguard VPN-  
+❌ Bence anonimlik değil.  
+
+✅ Ortak Wi-Fi'da tüm trafiğin VPS'ine kadar şifreli gider.  
+
+✅ Nextcloud, Gitea, SSH gibi servislerine güvenli şekilde bağlanırsın.  
+
+✅ İstersen SSH ve yönetim panellerini yalnızca VPN'den erişilebilir yapabilirsin.  
+
+✅ DNS sorgularını da kendi sunucundan geçirerek yerel ağın bunları görmesini engelleyebilirsin.
