VT AIR – Next Generation Firewall
VT AIR is the next gen firewall for the enterprise market. It belongs to the third generation of firewall technology. It combines proven technologies with the latest generation approaches.
The graphic shows the advantages of the VT AIR Next Gen Firewall at a glance. It offers effective protection and always focuses on prevention. VT AIR offers comprehensive network security because it prevents attacks in advance and does not offer hackers a gateway into your business. One thing is certain: In the digital world, comprehensive security is only possible with the latest technology. This means for your company: Using VT AIR, your data enjoy the highest level of protection.
VT AIR offers a variety of advanced threat protection mechanisms.
Blocking unwanted and unsafe websites via DNS sinkholing technology and advanced web filters with virus scanners and content filtering.
Various intrusion detection and protection rules are also available.
Application Control allows you to create firewall rules on the application level.
Traditional firewalls, which only identify ports, protocols and IP addresses, cannot identify and control applications, but a next generation firewall can. VT AIR Next Generation Firewall allows you to create firewall rules based on applications.
The Intrusion Detection and Prevention System (IDS / IPS) of the VT AIR Firewall significantly improves network security by providing complete and comprehensive real-time network protection against a wide range of network threats, vulnerabilities, exploits and threats in operating systems and applications.
VT AIR scans network traffic using powerful and comprehensive rules and signature language to detect complex threats with the Surricata program.
Suricata is an open source based intrusion detection system and intrusion prevention system
Automatic signature updates are provided regularly to ensure that the VT AIR Firewall is always up to date.
VT AIR supports the acceleration of TCP and UDP connections using Network Flow Fastpath.
For this purpose, the NFTables flow table offload technology is used, which accelerates network traffic by a factor of 2-3, all with the usual network security.
With Flowtables you can accelerate packet forwarding in software with the help of a state that no longer runs through the entire network stack after a connection has been established.
Multi-factor authentication (MFA) has become the standard to prevent unauthorized access to business-critical information.
VT AIR supports multi-factor authentication with the TOTP standard for the web interface and OpenVPN to protect your infrastructure in the best possible way.
VT AIR is a stateful firewall. A stateful firewall is a network firewall that tracks the operational status and characteristics of network connections that pass through them. The firewall is configured to distinguish between legitimate network packets for different connection types.
Packets are analyzed with NFTables (Deep Package Inspection) and allowed or blocked on the basis of firewall rules in order to ensure optimal protection of the network traffic.
Advanced Web Protection combines advanced analysis functions, blacklists and ACLs to optimally protect your web traffic.
With the built-in virus scanner, you can optimally protect your web traffic.
VT AIR uses the Squid program, which is characterized by its diverse functions and security.
The web filter can be set up as a proxy, but also as a transparent HTTP / HTTPS proxy.
With XDP, network functions (eBPF) can be executed as soon as a packet reaches the network card and before it is moved up into the kernel’s network subsystem, which leads to a significant increase in packet processing speed. This technology allows us to achieve significantly faster firewall speeds.
In general, all of our VT AIR appliances are already prepared for XDP / eBPF.
This technology will be available in VT AIR in 2021.
The IEEE 802.1X standard provides a general method for authentication and authorization in IEEE 802 networks. At the network access, a physical port in the LAN, a logical IEEE 802.1Q VLAN or a WLAN, a participant is authenticated by the authenticator, who uses an authentication server (RADIUS server) to check the authentication information transmitted by the participant (supplicant) and, if necessary, the Permits or denies access to the services offered by the authenticator (LAN, VLAN or WLAN).
VT AIR has both an 802.1X authenticator and an 802.1X supplicant.
A captive portal is a facility that is usually used in public, wireless networks in order to link the access of end devices such as laptops or smartphones to the underlying network or the Internet to the user’s consent to certain usage rules. In addition, the network provider can link access to a specific user account. VT AIR allows you to set up a captive portal for each interface with its own HTML page for authentication.
VT AIR comes with a built-in IPv4 and IPv6 Kea DHCP server.
Whether static or dynamic DHCP addresses and multiple networks, you can supply your clients with addresses without any problems.
The Kea DHCP server is also capable of high availability and can form an automatic failover with several VT AIRs.
VT AIR comes with the well-known Unbound DNS Server, which allows it to run as a stand-alone or as a forwarding DNS server. Unbound allows you to define any host overrides and domain forwarding. For security reasons, VT AIR uses different DNS block lists with categories. Encrypted DNS and DNSSEC are also not a problem.
Docker is a range of platform-as-a-service products that use virtualization at the operating system level to deliver software in packages. These are known as containers. Containers are isolated from each other and bundle their own software, libraries and configuration files. They can communicate with each other via precisely defined channels. VT AIR has support and management via the WebGUI for Docker.
HAProxy is free, open source software that provides a highly available load balancer and proxy server for TCP and HTTP-based applications that distribute requests across multiple servers. VT AIR has full support for setting up and operating a HAProxy via the web interface.
ntopng is a software for monitoring data traffic on a computer network. It was developed as a powerful and resource-effective replacement for ntop. With ntopng on VT AIR you can analyze and monitor your network traffic per interface, host or network segment.
Network Time Protocol is the most common method of synchronizing a system’s software clock with Internet time servers. It is designed to mitigate the effects of variable network latency and can typically limit the time over the public Internet to ten milliseconds. The accuracy in local networks is even better with up to a millisecond. VT AIR comes with an NTP server for the network clients.
The Simple Network Management Protocol is a standard Internet protocol used to collect and organize information about managed devices on IP networks and modify that information to change device behavior. VT AIR supports SNMPv1 / v2 and the encrypted SNMPv3 for high security. Read all the attributes of the firewall with SNMP, with the special VT AIR SNMP mibs you have full control over your monitoring.
FRR is used for dynamic routing, which allows BGP and OSPF (v4 or v6).
VT AIR offers high firewall performance with NFTables, Flowtable Offload Technology and, in the future, XDP / eBPF.
VT AIR comes fully equipped with high availability functionality. Use virtual IPs (VRRP) between multiple VT AIRs to enable failover without interruptions. The VT AIR configuration is automatically transferred from the master to the slaves and DHCP can also be used in HA operation to compensate for a failure. High availability is a must for critical installations and VT AIR enables smooth operation.
VT AIR offers a multitude of options for using and configuring interfaces. Real Interface, VLAN, QinQ, Bond, Bridge, PPP, PPTP, GRE, IPIP, SIT SHDSL, VDSL and MacVLAN are supported. In addition, various settings can be made IPv4 / IPv6, Static IP, DHCP Client, SLAAC, Mac, MTU, MSS, Link Mode, 802.1x (Suplicant) … and much more.
VT AIR offers static and dynamic routes. Gateways can be monitored using ping and intelligently interconnected in routing tables, either in failover or load balancing mode. A policy routing can also be set using firewall rules or a routing table can be assigned to clients. FRR is used for dynamic routing, which allows for BGP and OSPF (v4 or v6).
QoS is implemented with the Linux tool Traffic Control (TC) and allows incoming (ingress) or outgoing (egress) traffic to be classified according to categories and rules. QoS can easily be assigned to clients via firewall rules.
Internet Protocol Security (IPsec) is a protocol suite that enables secure communication over potentially insecure IP networks such as the Internet. VT AIR offers full support for IPSec with Strongswan. Whether tunnel or transport mode, with or without an interface, with VT AIR you can connect your locations conveniently and securely.
OpenVPN is free software for setting up a virtual private network (VPN) via an encrypted TLS connection. VT AIR supports OpenVPN as a client or as a server and enables you to set up a VPN for your employees quickly and easily.
WireGuard is free software for setting up a virtual private network (VPN) via an encrypted connection. WireGuard enables a very fast and modern VPN. VT AIR supports WireGuard natively, whether for clients, site to site or mesh.
WebVPN allows you to access an RDP / VNC / SSH or Telnet server via a WebVPN portal via the browser. VT AIR allows your users to access the devices with the browser without a client.
The modern, easily understandable and dynamic web interface, which is created in numerous languages, allows you to make all settings conveniently and easily – in the interests of the user.
VT AIR comes with a modern REST API interface, via which all settings can be made conveniently and easily. Regardless of whether you have 1 or 1000 devices, with the REST API, the settings on all devices can be changed in seconds.
VT AIR offers a central management portal where you can see all devices in one place and thus easily access them. With our secure and innovative connector, you can directly access the web interface or the command line in the portal or run updates directly.
