Network Firewall
What problem does it target?
Network Firewalls address the risk of unauthorized access, malware, and attacks by controlling and monitoring incoming and outgoing network traffic based on predetermined security rules.
What does this solution do?
Network Firewall platforms:
- Inspect and filter network traffic at the perimeter or between segments
- Block unauthorized access and known threats
- Support stateful inspection, deep packet inspection, and application awareness
- Provide logging, alerting, and reporting features
Who is this for?
- Organizations of all sizes
- Security and network operations teams
- Enterprises with compliance requirements (PCI DSS, HIPAA, etc.)
Who might not benefit from this?
- Small businesses with no networked systems
- Environments relying solely on cloud-native controls
Pitfalls and remedies
| Pitfall | Remedy |
|---|---|
| Misconfigured rules leading to gaps | Regularly review and update firewall policies |
| Performance bottlenecks | Use hardware acceleration or cloud-based firewalls |
| Overly permissive rules | Apply least-privilege and segment networks |
