Micron21’s Firewall Solutions: Open Source Options for Flexible Security

Micron21 offers a range of firewall solutions, including enterprise-grade hardware firewalls such as Juniper SRX and Fortinet FortiGate firewalls. For clients seeking a cost-effective, open-source alternative, we provide mCloud Firewall, which comes free with all mCloud services and is based on OpenStack’s Neutron. Additionally, we support the deployment of pfSense and OPNsense virtual firewalls for those requiring advanced security features.

Open Source Firewall Solutions

mCloud Software-Defined Networking (SDN)

mCloud provides advanced SDN capabilities, including:
✔ Distributed Firewall as a Service (FWaaS)
✔ Layer 4 Load Balancing
✔ Native IPsec VPN for Site-to-Site Connections
✔ Floating IPs for Dynamic Address Mapping

Distributed Firewall Service with OpenStack Neutron

Within the mCloud portal, users gain access to firewall services directly integrated into OpenStack Neutron networking. This enables distributed firewall functionality at the compute node level, reducing network bottlenecks and eliminating single points of failure.

Security Groups & Stateful Filtering

mCloud users can create security groups with stateful filtering, allowing them to:
✔ Define firewall rules for TCP, UDP, ICMP protocols.
✔ Control source and destination IPs, ports, and traffic direction (ingress/egress).
✔ Apply dynamic firewall rules that evolve with network changes.

Advantages of mCloud’s Neutron Firewall

✔ Distributed Architecture: Reduces latency and prevents bottlenecks.
✔ Scalability: Seamlessly expands with infrastructure growth.
✔ Cost-Effective: Included free with all mCloud services.
✔ Ease of Management: Fully configurable through the mCloud portal.

Considerations

While mCloud Neutron Firewall provides essential security, businesses requiring advanced security features may benefit from additional firewall solutions.

pfSense and OPNsense Virtual Firewalls

For clients needing more advanced features, Micron21 supports the deployment of pfSense and OPNsense virtual firewalls. These open-source firewalls provide enterprise-level functionality comparable to commercial solutions.

What Are pfSense and OPNsense?

✔ pfSense: A FreeBSD-based firewall/router with firewalling, routing, VPN, DHCP, and DNS services.
✔ OPNsense: A fork of pfSense, offering similar features with a user-friendly interface and frequent updates.

Key Features

✔ Advanced Firewall Capabilities: Stateful packet inspection, NAT, and granular rule configuration.
✔ VPN Support: IPsec, OpenVPN, and PPTP for secure remote connectivity.
✔ Intrusion Detection & Prevention (IDS/IPS): Integrates Snort or Suricata for detecting threats.
✔ Traffic Shaping & QoS: Prioritizes bandwidth allocation.
✔ Extensive Package System: Extend functionality with antivirus, proxy servers, and monitoring tools.
✔ User-Friendly Web Interface: Simplifies firewall management.

Centralized Firewall Architecture

Unlike mCloud Neutron’s distributed model, pfSense and OPNsense function as centralized firewalls, inspecting all network traffic through a single firewall VM.

Advantages of pfSense/OPNsense

✔ Feature-Rich: Provides granular control over security policies.
✔ Customization: Highly configurable to match business needs.
✔ Comprehensive Logging & Reporting: Ensures thorough network monitoring.
✔ Community Support: Extensive documentation and support resources.

Considerations

✔ Resource Requirements: The firewall VM must be adequately resourced to avoid network bottlenecks.
✔ Single Point of Failure: Redundancy planning is required to mitigate risks.
✔ Management Complexity: More features require additional configuration.

Choosing Between mCloud Neutron Firewall and pfSense/OPNsense

✔ mCloud Neutron Firewall is ideal for:

• Clients seeking basic security integrated into mCloud services.

• Distributed environments requiring low-latency firewalling.

• Organizations looking for a free and scalable firewall solution.

✔ pfSense/OPNsense Virtual Firewalls are suitable for:

• Businesses requiring advanced security policies and firewall rules.

• Organizations needing VPN, intrusion detection, and traffic shaping.

• Companies preferring centralized firewall management.
