Overview

In an era of sophisticated cyberattacks and hybrid IT environments, misconfigured firewalls remain a leading cause of data breaches, compliance failures, and lateral movement by attackers. Many organizations—especially those with complex networks or multi-cloud setups—rely on outdated rulesets, overly permissive policies, or unmonitored exceptions, leaving critical assets exposed. Firewall Configuration Reviews eliminate these risks by auditing your firewall rules, policies, and architectures against industry best practices, ensuring your first line of defense is robust, compliant, and attacker-resistant.

What is Firewall Configuration Reviews?

Firewall Configuration Reviews is a detailed security assessment that evaluates the integrity of your network, cloud, and web application firewalls (WAFs). Our certified firewall experts analyze rulesets, access controls, logging configurations, and threat prevention policies to identify misconfigurations that could allow unauthorized access, data exfiltration, or compliance violations.

Key Focus Areas

Our reviews prioritize critical firewall risks, including (but not limited to):

✅ Overly Permissive Rules (e.g., “ANY-ANY” policies, open RDP/SSH ports)
✅ Shadow Rules & Orphaned Policies (unused or conflicting entries)
✅ Insecure VPN Configurations (weak encryption, split tunneling flaws)
✅ Lack of Segmentation (flat networks, weak DMZ controls)
✅ Logging & Monitoring Gaps (disabled traffic logging, missing alerts)
✅ Compliance Violations (PCI DSS Rule 1.3, HIPAA §164.312)
✅ Cloud Firewall Misconfigurations (overly broad Security Groups, exposed APIs)
✅ WAF Bypass Risks (improper input validation, missing rate limiting)
✅ Third-Party Access Risks (unvetted partner/IP whitelists)

How We Execute Firewall Configuration Reviews

We combine automated analysis with manual expertise for precision:

1. Asset Discovery & Rule Inventory

   • Map all firewalls (on-premises, cloud, WAFs) and their rulesets.

2. Automated Policy Analysis

   • Use tools like Tufin, AlgoSec, or native vendor utilities to flag risky rules.

3. Manual Deep-Dive

   • Review:

     • Rule order and specificity (e.g., overly broad rules masking stricter policies)

     • Geo-IP restrictions and IP whitelist/blacklist hygiene

     • Stateful inspection and threat prevention settings

4. Attack Simulation

   • Test rule effectiveness by simulating malicious traffic (e.g., port scanning, SQLi payloads).

5. Compliance Audits

   • Validate alignment with PCI DSS, NIST 800-41, and CIS Benchmarks.

6. Prioritized Reporting

   • Deliver findings ranked by exploitability, including:

     • Critical: Direct internet exposure of sensitive services

     • High: Unrestricted lateral movement paths

     • Medium: Compliance deviations

7. Remediation Playbooks

   • Provide firewall rule templates, Terraform/CloudFormation snippets, and policy templates.

8. Continuous Monitoring Setup

   • Recommend tools for ongoing firewall policy governance (e.g., AWS Firewall Manager, Palo Alto Panorama).
