Firewall security to help protect your
digital assets
Azure Firewall is a managed, cloud-based network security service that protects your Azure Virtual Network resources.
The stateful firewall service has built-in high availability and unrestricted cloud scalability to help you create, enforce,
and log application and network connectivity policies across subscriptions and virtual networks.
Threat intelligence–based
filtering
Enable real-time alerts and deny traffic
from/to known malicious IP addresses and
domains.
Deploy and scale in minutes
Simplify deployment and management of
your network security with a scalable and
highly available cloud native firewall.
Full visibility and protection
Transport Layer Security (TLS) inspection
prevents malware from being transmitted
through encrypted connections.
Unified management
Centrally manage security across all virtual
networks with a common set of network
and application rules.
Strengthen your network security posture
Get advanced threat protection that meets the needs of highly
sensitive and regulated environments. Azure Firewall taps into
real-time security signals from a wide range of sources using
Microsoft threat intelligence to guard against evolving threats and
zero-day vulnerabilities.
Deploy a stateful firewall in minutes
Enable turnkey firewall security capabilities in Azure Virtual
Network to control and log access to apps and resources. Azure
Firewall supports filtering for both inbound and outbound traffic,
internal spoke-to-spoke connections, and hybrid connections
through Azure VPN and ExpressRoute gateways.
Prevent malware and viruses from
spreading
Azure Firewall decrypts outbound traffic, performs required
security checks, and then encrypts the traffic to the destination. It
works in conjunction with URL filtering and web categories by
letting administrators allow or deny user access to website
categories such as gambling or social media.
Inspect traffic in real time
The intrusion detection and prevention system (IDPS) capability
uses signatures to continuously monitor activities, generate alerts,
log information, and optionally attempt to block the attack. It can
detect attacks in all ports and protocols for non-encrypted traffic.
Encrypted traffic utilizes the TLS inspection capability for
decryption.
Comprehensive security and compliance, built in
Microsoft invests more than USD1 billion annually
on cybersecurity research and development.
We employ more than 3,500 security experts who
are dedicated to data security and privacy.
Azure Firewall pricing
Setup is easy, and billing comprises a fixed per-hour consumption rate and variable fees based on
traffic. There are no upfront costs or termination fees—pay only for what you use.
