What are Cloud Firewalls?
Cloud Firewalls are security gateways that monitor, filter, and control incoming and outgoing network traffic to and from your cloud workloads. Unlike traditional firewalls, they’re built to scale dynamically, protect against advanced threats, and provide visibility across hybrid and multi-cloud environments. Properly configured cloud firewalls are the first line of defense for safeguarding applications, APIs, and sensitive data in the cloud.
Why Cloud Firewalls are Critical?
As businesses migrate to AWS, Azure, GCP, or private clouds, traditional perimeter defenses alone aren’t enough. Misconfigurations, weak rules, or open ports can leave your infrastructure vulnerable.
Cloud Firewalls help you:
- Block malicious traffic before it reaches your workloads
- Enforce Zero Trust access policies across distributed teams
- Prevent lateral movement of attackers within your environment
- Monitor and log all network activity for compliance and forensics
- Meet regulatory requirements (ISO 27001, SOC 2, PCI DSS, RBI, SEBI, HIPAA)
