Affordable,  Easy-to-Use,  Reliable

A firewall is your first line of defense against intrusion, email, and http viruses, worms, spam and content filtering (surf protection).  Tucan recommends and sells Astaro firewalls, the most reliable firewalls on the market.  Astaro is the industry leader in security.

The Astaro firewall manages inbound and outbound communications traffic. It is installed on any standard PC hardware and placed at the point where the Internet enters your facility, controlling network traffic for security purposes.

 A user-friendly point-and-click interface allows Administrators to block or allow access, for each protocol, to each internal network, server, service, and user group. The firewall inspects both networking information (packet headers) and application information (payloads) to detect and block suspicious traffic.

Astaro's Firewall features:

Stateful Packet Inspection (standard firewall capability)
Astaro's firewall inspects network packet headers to manage traffic between the Internet and internal networks, servers, and users. The firewall examines individual packet headers to make sure that they conform to the rules of the appropriate protocol (packet filtering), and tracks the sequence of events during ongoing connections to detect violations of normal processes (stateful packet inspection).  (view online demo)

Application-Level Deep Packet Filtering
The Astaro firewall utilizes application-level proxies to scan the application-related content of communications packets (payloads) to ensure conformance with rules specific to web traffic, email, DNS, and other broad application types.

Security Proxies
Astaro's firewall provides comprehensive proxies that simplify management by allowing administrators to quickly and easily enable and disable protocols and features such as content filtering, caching, whitelists and blacklists, file extension filtering, and MIME error checking. Proxies are included for the protocols:
HTTP  |   DNS  |   SOCKS   |  POP3  |   Ident   |  SMTP

NAT and Masquerading
Dynamic and static Network Address Translation (NAT) and masquerading conceal internal IP addresses behind a "public" IP address, to prevent hackers from learning about internal networks, servers, and users.

DoS Protection
Astaro's firewall protects against common Denial of Service (DoS) attacks like TCP SYN flood, ICMP flood, UDP flood, Smurf, Trinoo, and IP spoofing.

Traffic Shaping and QoS
Administrators can increase or decrease the priority of different types of traffic between specific endpoints, providing quality of service (QoS) for critical transactions.

Detailed Reporting
Astaro provides detailed reporting on network traffic, connections, packet filter violations, hardware utilization on the firewall system, and other information for managing the firewall.
