Intrusion Detection and Prevention (IDPS)	Not available	Not available	Yes, offers advanced threat protection with signature-based IDPS
TLS Inspection	Not available	Not available	Yes, decrypts and inspects encrypted traffic for threats
Web Application Firewall (WAF) Integration	Not available	Not available	Yes, can be integrated with Azure Application Gateway WAF for enhanced application layer protection
High Availability	Built-in	Built-in	Built-in
VPN Gateway Integration	Limited	Yes	Yes
Bandwidth	Pay-as-you-go for data processed	Pay-as-you-go for data processed	Pay-as-you-go for data processed, plus costs for TLS inspection and IDPS
Pricing (Estimation)	Lower cost option, suitable for small to medium-sized deployments	Higher cost than Basic, reflects the inclusion of advanced network protection features	Highest cost, includes advanced security features like IDPS and TLS inspection
Use Cases	Suitable for basic network security needs, such as simple segmentation and filtering	Suitable for businesses requiring advanced network and application layer protection	Designed for organizations with high security and compliance needs, including finance and healthcare

Pricing Specifics:

• Basic: Generally the most cost-effective option, aimed at small to medium deployments. Pricing is primarily based on the amount of data processed.
• Standard: Costs more than Basic due to additional features. Pricing includes a fixed monthly rate plus additional costs based on data processing and rule count.
• Premium: The most expensive tier, reflecting the inclusion of premium security features. Pricing involves a fixed monthly rate, higher data processing fees, and additional charges for features like TLS inspection and IDPS.

Basic: The Essential Guard for SMBs

Think of Basic as the lean, mean security machine for small and medium businesses (SMBs). It offers the core protection you need at an attractive price point:

• Stateful firewall: Monitors incoming and outgoing traffic, filtering based on IP addresses, ports, and protocols.
• Threat intelligence: Leverages Microsoft’s security expertise to block malicious IP addresses and domains.
• Application rules: Granular control over specific applications within your network.
• Limited scalability: Suitable for workloads up to 250 Mbps.

Standard: Enterprise-Grade Security at Scale

If your needs transcend basic protection and encompass larger-scale deployments, Standard steps onto the scene. It builds upon Basic’s features with:

• Advanced Layer 3-7 filtering: Deep inspection of traffic content, enabling you to block specific data types or malicious payloads.
• Web categories: Block access to unwanted categories like gambling or social media, enhancing employee productivity.
• Custom DNS: Direct traffic to specific DNS servers for enhanced control and security.
• Autoscaling: Adapts to fluctuating traffic demands, handling bursts up to 30 Gbps.

Premium: Uncompromising Protection for High-Sensitivity Data

For applications handling sensitive data or requiring the ultimate security posture, Premium pulls out all the stops:

• Intrusion detection and prevention system (IDPS): Continuously monitors for suspicious activity and actively blocks known threats.
• TLS inspection: Decrypts and inspects encrypted traffic, safeguarding against hidden malware or data breaches.
• PCI DSS compliance: Meets Payment Card Industry Data Security Standard (PCI DSS) requirements for secure payment processing.
• Advanced threat intelligence: Integrates with Azure Sentinel for broader threat insights and incident response.

Choosing Your Champion: A Quick Guide

• For cost-conscious SMBs with basic security needs: Basic is your champion.
• For enterprises seeking advanced filtering, scalability, and web filtering: Standard rises to the challenge.
• For organizations handling sensitive data, requiring IDPS, PCI DSS compliance, or advanced threat protection: Premium reigns supreme.

Remember, your choice depends on your unique security posture, budget, and compliance requirements. Evaluate your specific needs and don’t hesitate to consult with Azure experts to ensure you’ve chosen the optimal firewall tier for your cloud fortress.

Bonus Tip: Consider combining tiers for a layered defense. For example, you could use Basic for less critical workloads and Premium for highly sensitive applications.

By understanding the strengths of each Azure Firewall tier, you can make an informed decision that safeguards your cloud environment and empowers your business to thrive. So, choose wisely, security guardians, and let your Azure Firewall be your impenetrable shield!
