Monitor and control incoming and outgoing network traffic based on predefined security rules. Its purpose is to prevent unauthorized access to a system and protect data from external threats.
Firewalls are essential to protecting systems from unauthorized access, filtering malicious traffic, and serving as the first line of defense in network security. They help monitor network activity in real-time, prevent data leakage, and control access based on defined policies — ensuring only permitted traffic can enter or leave the network.
Firewall rule management and periodic tuning to ensure optimal performance and security.
Real-time firewall monitoring and incident handling to protect networks from cyber attacks.
Provide periodic security reports for audits and ensure compliance with industry standards.
Regular firmware updates, patching, and health checks keep your firewall reliable and up-to-date.
The firewall receives incoming or outgoing traffic and determines the source and destination zones (e.g., WAN, LAN, DMZ). It identifies the interface where the packet entered the network.
The packet is checked against configured firewall rules. The firewall evaluates parameters such as source IP, destination IP, port numbers, protocols, and user identity (if applicable).
Next-Generation Firewalls (NGFW) perform deep packet inspection (DPI) to detect malware, block unauthorized applications, and enforce content filtering or SSL decryption as needed.
The firewall makes a decision to allow, block, or reject the traffic. Actions are logged for auditing and, if configured, alerts are sent to administrators or SIEM systems for further analysis.
