FortiGate Cloud-Native Firewall (CNF) confronts a broad spectrum of security challenges that plague modern cloud environments, focusing on mitigating threats associated with unsecured outbound traffic.

These challenges include, but are not limited to:

  • Malware: FortiGate CNF provides robust protection against connections to compromised servers, which could lead to unintentional malware downloads. By monitoring and controlling outbound traffic, it prevents malware from infiltrating the network.
  • Data Exfiltration: The solution addresses the critical issue of data exfiltration by blocking compromised systems from communicating out and sending sensitive data to unauthorized systems. This is vital for safeguarding proprietary and personal data against external threats.
  • Command and Control (C2) Communication: It effectively cuts off compromised workloads from communicating with C2 servers. By preventing these communications, FortiGate CNF disrupts the ability of attackers to execute commands or steal data, thus neutralizing the threat.
  • Crypto Mining: By identifying and blocking connections to IPs known for exploiting cloud resources for crypto mining purposes, FortiGate CNF ensures that organizational resources are not siphoned off for malicious gain.
  • Compliance Violations: The solution enforces compliance by preventing unauthorized communications with restricted or prohibited countries, systems, or entities. This feature is particularly crucial for organizations needing to adhere to strict regulatory and compliance guidelines.


FortiGate Cloud-Native Firewall (CNF) offers a suite of key features designed to fortify cloud environments against a wide range of cyber threats, ensuring seamless integration, dynamic scalability, and stringent compliance with regulatory standards.

1. Egress Security: In today’s landscape, where cloud adoption is ubiquitous, securing egress traffic has become paramount. Egress security from FortiGate CNF mitigates risks such as data exfiltration, malware propagation, and botnet activities. It enables organizations to control traffic leaving their cloud environments, ensuring that sensitive data remains protected and that malicious communications are effectively blocked.

2. Known Bad IP Filtering: Leveraging FortiGuard Labs IP Reputation Intelligence, this feature enhances security by preventing access to malicious IPs and Command and Control servers. This proactive measure significantly reduces the risk of security breaches and cyber attacks, ensuring that organizational resources are safeguarded against known threats.

4. East-West Security: Protecting cloud-based workloads— including dynamic objects like serverless resources, Kubernetes resources, and auto-scaling groups— is essential for maintaining the integrity of internal networks. By enforcing network security policies dynamically, FortiGate CNF ensures comprehensive protection, facilitating secure communication and data transfer within cloud environments.

5. Dynamic Security: The ability to define security policies using intuitive objects (like countries, FQDNs, and AWS resource metadata) empowers organizations to adapt swiftly to changes in their cloud environments. This dynamic security approach reduces the need for constant manual policy updates, enhancing efficiency and responsiveness.

6. Regulatory Compliance: Assisting in meeting various regulatory compliance requirements, such as GDPR, HIPAA, and PCI-DSS, FortiGate CNF helps organizations protect sensitive data and maintain privacy standards. This capability is invaluable for businesses in highly regulated industries, providing a foundation for compliance and data protection strategies.

7. FortiGuard Labs Services: Integration with FortiGuard Labs ensures that FortiGate CNF benefits from up-to-date security intelligence, including multiple security signatures and IP reputation information. This integration enhances the overall security efficacy, offering proactive protection against emerging and existing threats.

8. AWS Firewall Manager Integration: The automation of VPC attachment and policy rollouts through AWS Firewall Manager underscores FortiGate CNF’s commitment to seamless integration and ease of use within the AWS ecosystem. This feature streamlines security management, allowing for more efficient and centralized control over cloud security policies.
