It would be very nice if Let's Encrypt certificates (letsencrypt.org) can be generated directly from the XG Gui. So that the "Let's Encrypt Client" is integrated in the XG. Would it be possible?

Scheduled Installation of the AV Updates and Firmware Installation is required. The firmware updates and AV Updates should get automatically downloaded over the WAN interfaces, however installation of this updates should be done only when the Date and time is scheduled by the Network Administrator.

In addition to the available scheduling options, the custom category should be added, where in the administrators can select a custom date and custom time, after selecting the custom date and custom time the system should prompt if these settings are just to be executed once, daily, weekly, every 15 days or monthly.

NTP Server is a small package and UTM9 has it. In some small organization, having a central NTP server is a nice feature.
Can you add it into future release?

You can put it inside device access, denying WAN from using NTP server for security reason.

It would be great to be able to see live Bandwidth speed stats for each Interface like we had on UTM.

XG does not have a anti-portscan feature. Please vote it!

At the moment, there is no way to disable/enable an interface inside SFOS.
Strange!Even using CLI menu.

At the moment no way to customize notification. I receive mail when the WAN gateway is down/up.
You need to provide us a way to create rules where we can decide when receive notification, alert level (warning, information, critical),who will receive the notification. As soon you integrate SMS, please also allow us to receive SMS (it is an old way) but when the mail does not work....
I would suggest you to create a panel as the Network Policy Rule rule to manage notification rules.

1- admin have rights to add and remove Tab on user Portal
2- User Portal with login integration SSO.
3- Company logo on user Portal
4- User just view blocked SMTP Quarantine email, they don't have right to release email.

UTM 9 had great DHCP options that you could assing globally or to an individual pool. For people with VoIP deployments this is Huge.

Currently, the WebAdmin Master-User is fix named as admin. It would be great, if we would have the possibility to change the username. This would be an improvement for brute-force attacks, when the WebGUI is somehow published to the Internet.

Sophos should develop an own VPN app for mobile operating systems (iOS / Android / Windows Phone) which can connect via the UTM using the configuration pushed from the UTM to the SMC server.
It should also support the Per-App-VPN feature which was introduced in iOS 7.

Add support to rename Policy rules name, IPSEC and SSL VPN tunnels name, Webfilter Policy and Category objects, Application Policy and Category objects, QOS rules and all other items.
This will Improve the management, it must be default to all objects. Currently to fix a simple typo error, we must to create a new policy or category and populate all items again. A simple task can turn into a hard task.

It would be very convenient to assign static ip to users logging in through SSL VPN client. Currently this feature is available only to L2TP and PPP users.

At home USB NICs are ideal. Exactly the same problem we had in UTM9. Link below.

Users to have ability to manage emails Whitelist and Blacklist via User Portal and quarantine report .

My ISP supports native IPv6, they support prefix delegation using DHCPv6-PD to assign a /56 subnet. They do not assign the WAN interface an IPv6 address (i.e. no IA-NA) and only provide a prefix delegation (IA-PD). Currently XG (and UTM9) doesn't work with my ISP to get a PD because there are no options to request IA-PD only. My ISP edge router will respond to a solicit message with a IA-NA and IA-PD request but it would appear that the XG doesn't conform to RFC7550 when it sends a IA-NA message and receives a "NoAddrsAvail" from my ISP edge router.

Include the possibility of signing outgoing emails using DKIM for all or only selected email domains as in UTM9

Add support to notification component send email to multiple recipients.

Currently it is supported only 1 recipient.

Improve the WAN Gateway monitor. Add Latency thresholds, Packet Loss thresholds.
This can help much to prevent false positive gateway status.
The same feature could be added on VPN Failover system
