Conclusion: A comprehensive all-in-one security solution for the small business that combines key Internet defences, including a firewall and VPN server, anti-virus and anti-spam tools, content filtering and intrusion detection facilities. It doesn't do away entirely with the need for desktop and server-side tools but it is a good first line of defence and provides a high degree of protection from common threats.
Conclusion: The Zywall 35 UTM is a capable Internet security appliance with unified threat management features for the small business. Its attractive price and easy configuration should make it a good alternative for those relying on desktop security only.
Pros: Good AV and signature-based intrusion detection system (IDS). Reasonable price. Easy installation and configuration.
Cons: IDS signature update sometimes unreliable. Spam and content filtering engines not from top-tier providers.
