The challenge
Your organization faces an ever-increasing volume of sophisticated cyber threats. Maintaining a strong security posture requires more than just basic perimeter defense. Outdated or poorly configured firewalls can leave your network vulnerable to breaches, leading to data loss, service disruptions, and regulatory fines. Managing complex firewall rules and keeping up with the latest threats can overwhelm your IT team, creating operational inefficiencies and increasing your overall risk.

The solution
Network firewall addresses your unique challenges through modern solutions and key capabilities.
Threat intelligence
Leverage real-time threat intelligence feeds to proactively block known malicious IPs, domains, and malware signatures, reducing the attack surface.
Deep packet inspection (DPI)
Analyze the content of network traffic at the application layer to identify and block threats that bypass traditional port-based filtering.
Identity-aware policies
Enforce granular access control based on user identity and role, ensuring consistent security policies regardless of location.
AI-powered threat detection
Use machine learning algorithms to identify anomalous network behavior and zero-day attacks in real-time, without relying solely on signature-based detection.
Cloud-native security
Extend firewall protection to cloud workloads and remote users with Firewall-as-a-Service (FWaaS) and Secure Access Service Edge (SASE) architectures.
Automated rule management
Automate the process of identifying and decommissioning unused or redundant firewall rules to reduce complexity and improve security posture.

How to evaluate network firewall
1
Deployment flexibility
Evaluate whether the vendor offers physical appliances, virtual firewalls, and cloud-native services to support your hybrid or multi-cloud environment.
2
Security throughput
Verify the firewall's performance with all security features enabled, not just the raw throughput.
3
Integration capabilities
Ensure seamless integration with your existing identity providers (IDP) and security information and event management (SIEM) systems.
4
Total cost of ownership (TCO)
Consider all costs, including software licenses, professional services, support, training, and usage-based fees.

Network firewall RFP guide- Can you provide a performance benchmark showing throughput with TLS 1.3 decryption, IPS, and Application Control all enabled simultaneously?
- How does your solution identify and automatically suggest the decommissioning of unused or redundant rules?
- Does your AI-based threat prevention operate 'inline' to block malicious packets in real-time, or does it require sending files to an out-of-band sandbox for analysis?
- What specific tools or services do you provide to automate the migration of our current rule base from our legacy vendor to your platform?
