Find the Misconfigurations Hiding in Years of Firewall Rules.
A Network Device Configuration Review is a systematic audit of your firewalls, routers, switches, load balancers, and other network infrastructure against industry security benchmarks — primarily CIS (Center for Internet Security) Benchmarks and vendor-specific hardening guides.
Most Indian businesses deploy network devices, configure them once during setup, and rarely review those configurations again. Over time, temporary rules become permanent, exceptions accumulate, and the gap between your intended security policy and actual configuration grows wider. This is exactly the gap attackers exploit.
Configuration review examines every rule, every ACL, every routing policy, and every management interface setting on your network devices. We compare your actual configuration against proven security baselines and identify deviations that create risk — from overly permissive firewall rules to default SNMP community strings that have never been changed.
In our experience reviewing network configurations for Indian enterprises, we find an average of 23 configuration deviations per device. That includes firewall rules allowing traffic that should be blocked, management interfaces accessible from untrusted networks, default credentials that were never changed, logging disabled or misconfigured, and outdated firmware with known vulnerabilities.
The most common finding across Indian businesses is firewall rule bloat. Over years of operation, temporary rules are added for troubleshooting, vendor access, or specific projects — and never removed. We regularly find firewalls with 500+ rules where 30-40% are redundant, contradictory, or overly permissive. Each unnecessary rule is a potential attack path.
For regulated industries — banking, insurance, fintech — RBI and CERT-In explicitly require regular security reviews of network infrastructure. A configuration review provides the evidence auditors need while actually improving your security posture.
Every Network Device Configuration Review engagement with Verentix delivers concrete, actionable outcomes:
Device Inventory and Baseline (Day 1-2): We catalogue every network device, collect running configurations (read-only access), and establish the CIS Benchmark baseline applicable to each device type and vendor.
A banking group in Mumbai had their core firewall reviewed after 4 years of continuous operation. We found 847 active rules — of which 312 were redundant or contradictory. After our review and cleanup recommendations, the rule base was reduced to 535 effective rules, improving both security and firewall performance by 18%.
A manufacturing company in Pune discovered during our review that their switch management interfaces were accessible from the production VLAN — meaning any compromised production system could reconfigure network infrastructure. The default SNMP community string 'public' was still active on 14 out of 18 switches.
An IT services company in Hyderabad found that their load balancer was still running TLS 1.0 and accepting weak cipher suites — a direct PCI DSS violation. Our review identified this along with 28 other configuration deviations across their network infrastructure.
