What you get
Everything a small or mid-sized office server has to do.
Directory & domain
Native Active Directory implementation — join Windows clients, apply GPOs and manage users exactly as your admins already do.
Mail & groupware
A full SMTP/IMAP mail stack with webmail, shared calendars and contacts, ActiveSync and antispam built in.
Network & gateway
DNS, DHCP, firewall, VPN, HTTP proxy and CA — the infrastructure layer of the office in one interface.
One license, no CALs
Unlimited users and devices on every edition. Predictable yearly pricing, or a lifetime license if you prefer to own it.
Migration
Leave Windows Server without leaving your users behind.
Zentyal speaks the same protocols your network already uses, so migration can become a weekend project rather than a re-platforming programme.
