Firewall is a software that imposes a set of rules to decide on what data packets are to be allowed to leave or enter the network. The firewalls are incorporated to sift the traffic and to mitigate the possible security risks associated with the malicious packets that traverses over the public internet. Firewalls restrict suspicious or illegitimate access from or to a network. They form a comprehensive security system for your network. Firewalls come along as a security feature along with other security features of a security suite package or it also comes as stand-alone software applications.
• Packet-Filtering Firewall
• Stateful Inspection Firewall
• Proxy Firewall
• Next Generation Firewall
• A packet-filtering firewall – this helps to validate the data packets separately not knowing the context of the packet.
• A stateful Inspection Firewall – validate the network traffic to check one packet is related to the other packet.
• A proxy firewall investigates the data packets right at the application layer
• Next Generation Firewall implements a multiple-layered strategy and incorporates the functionalities of enterprise Firewall with Host Intrusion Prevention System (HIPS) and application control.
Secure Web Gateway is used to monitor and restrict suspicious malware traffic and data from entering or leaving the network of the organization. It secures the network from Internet-based threats or malicious threats from Web products/services and websites. Unlike conventional firewall, secure web gateway incorporates 7-layered we traffic Inspection. URL filtering, data leakage prevention, application-level control and detection of malware code are some of the key features of Secure Web Gateway while traditional firewall provides basic protection by blocking and alerting the user on malicious connection attempts. It also permits the users to frame a set of rules to control to decide which programs can or cannot access the LAN (Local Area Network) and the Internet and notifies the user when a suspicious application tries to establish a connection attempt.
The Next Generation Secure Web Gateway provides multi-layered protection to ensure protection while using Web 2.0 against malware originated from the web. It delivers enhanced granular-level control, centralized management, end user education capability. It is efficient to terminate access to malicious website and restricts the use of applications that can possibly put the users at risk,
The next generation secure web gateway benefits the users by preventing malware infections and by providing restoration from damage after the malware infection with the approach of multi-layered security. It also improves the operational efficiency with future-proof security management.
UTM or Unified Threat Management Firewall is network hardware system or cloud service that protects business from malicious threats by collaborating multiple facets of security features and services through a single platform.
Comodo Dome Firewall is considered the best UTM Firewall to deliver Advanced Threat Protection, Intrusion Protection, URL filtering to safeguard the internal network from unknown and untrusted external threats. Unlike other conventional firewalls, Comodo dome Firewall implements packet inspection to protect all the protocols and ports. It follows by a set of rules to control both inbound and outbound traffic. It performs static and behavioural analysis by integrating containment technology for unknown and suspicious files to stay protected against phishing, and botnets at the gateway. It also blocks URLs based on custom-domain categorization.
