CacheGuard Features Overview
CacheGuard Features include all Security and Optimization functionalities that you may need for your Web traffic. Those features, all together in one package, provide you the highest level of integration and ease the tasks of configuring and administering a network appliance. Below you can find an overview of all features provided by CacheGuard Web Gateway.
CacheGuard Antivirus inspects the Web traffic at the gateway and eradicates all dangerous contents before they can enter into your networks. You stumbled upon a Web page on the darknet? You received an email with a suspicious link that you accidentally clicked on it? CacheGuard instantly blocks that suspicious contents and logs the access attempt. CacheGuard Antivirus can also be used as a service by external systems such as an MTA (Mail Transfer Agent) to block malware reaching your infrastructures via protocols other than HTTP/HTTPS. Learn more at Gateway Antivirus.
CacheGuard Features include a guarding mechanism against unwanted URLs. CacheGuard URL Guarding (Filtering) uses blacklists, white lists and regular expressions to allow or disallow websites accesses thus increasing the productivity of your users while keeping you safe from malicious websites. The URL Guarding coupled with your LDAP or AD/Kerberos authentication server allows you to define your own sophisticated Web access policies. Learn more at URL Guarding.
CacheGuard Firewall protects PCs, servers or any other connected devices from hostile intrusions from the Internet and/or external networks. CacheGuard Firewall enables stateful packet filtering, Network Address Translation (NAT) and Port Address Translation (PAT) and is fully customizable to fit your needs. It innately integrates smart rules that block attacks such as DDOS (SynFlood, Smurf, XMas…) and IP spoofing. Learn more at Firewall.
Authentication allows you to restrict the Web access to authenticated users only, thus preventing the Web access to non authorized users or intruders. CacheGuard Authentication supports LDAP, LDAPS and the Kerberos authentication compatible with Microsoft® AD®. The LDAP/LDAPS authentication can be enabled for internal users as well as for external users of your internal Web applications cloaked/protected by CacheGuard Web Gateway.
Bidirectional Web Proxy
Accessing the Web via a proxy allows you don’t expose your IT infrastructures directly to the Internet. The Web Proxy is at the core of CacheGuard and can be implemented transparently to users and Web applications. In forwarding mode the Proxy secures and optimizes the Web traffic destined to Web users while in reverse mode it secures and optimizes the Web traffic destined to Web applications. The Web Proxy and the Reverse Proxy can be activated at the same time on the same CacheGuard without the risk of mixing forwarding and reverse Web traffic by isolating each type of traffic in a distinct VLAN. Learn more at Forwarding Proxy and Reverse Proxy.
WAF (Web Application Firewall)
Because cyber-attacks have become increasingly sophisticated, blocking threats at the IP level only with traditional firewalls is not enough to provide an acceptable level of security to Web applications. CacheGuard WAF (Web Application Firewall) protects your Web applications against a range of content oriented attacks such as Protocol Violation, Protocol Anomaly, Session Fixation, SQL injection, XSS (Cross Site Scripting), File injection, Command access, Command injection and LDAP/SSI/PHP injection. Learn more at WAF.
Once implemented in reverse mode, CacheGuard acts as an SSL Offloader in order to inspect the content of encrypted Web traffic (HTTPS) exchanged with Web applications that it cloaks and protects. Content filtering features such as the WAF and the Antivirus are then fully operational and can block threats even in an encrypted format. At the same time a bunch of load balanced Web servers cloaked by CacheGuard are offloaded from the redundant task of encrypting/decrypting the Web traffic. Hence, you optimize the usage of your CPU/RAM resources and increase the overall performance of your infrastructures.
The SSL Mediation (or Inspection) enables the decryption of encrypted Web traffic (HTTPS) at the Gateway in order to cache and/or inspect its content. Therefore, the CacheGuard Antivirus can be fully operational and block all attempts to access malware even in an encrypted format. When the SSL Mediation is activated, CacheGuard re-encrypts decrypted traffic before forwarding it to users. Learn more at SSL Inspection.
With CacheGuard you can design scalable architectures to provide the right QoS (Quality of Service) at the right time. Implement your first CacheGuard for your current needs and switch to a dual (or more) Web Gateway architecture later if necessary. You can also balance the total Web traffic load among backend Web servers and make sure your users always have access to Web applications even when one or more Web servers are down.
CacheGuard Traffic Shaper allows you to distribute appropriate bandwidth to users, allowing you to give your power users quicker access to the Web. When implemented in front of your Web applications, CacheGuard can shape the Web traffic in order to allocate the right bandwidth to Web applications according to their criticality. Reserving adequate bandwidth for Web applications ensures that Web applications are always available to serve users according to your actual needs. Learn more at Traffic Shaping.
Caching and Compressing
With CacheGuard you have the possibility to cache the Web content and transmit it in a compressed format, thus saving your bandwidth and in some cases accelerating the Web traffic. Caching and compressing help ensure to deliver the Web content quickly and smoothly to your local users as well as to your remote users. The Caching, Compressing and Traffic Shaping all together allow you to optimize your Web traffic and consequently lower your costs.
CacheGuard HA (High Availability) Feature provides your users with continuous uninterrupted access to the Web. To do so, 2 or more CacheGuard Web Gateways can be implemented in HA mode in order to provide a SPoF-less (Single Point of Failure) architecture, thus increasing your SLA (Service Level Agreement). The HA mode can be activated in forwarding mode to secure your internal users as well as in reverse mode to secure your Web applications.
To be monitored, CacheGuard supports the SNMP (Simple Network Management Protocol) standard. CacheGuard can be configured to send SNMP traps to monitoring systems such as Nagios. It also embeds an an SNMP agent that can be polled using your favourite SNMP monitoring tool.
