Run a VAPT Before You Buy Your Next Firewall

Most NGFW purchases are triggered by a vendor demo or a renewal cycle — not by evidence of what your actual attack surface looks like. We've walked into post-purchase deployments where a ₹12L firewall was correctly configured for entirely the wrong problem.

What a VAPT report tells you that a vendor won't

A network VAPT shows you open ports your own team forgot about, misconfigured services on non-standard ports, and lateral movement paths between VLANs you assumed were segmented. It tells you whether your biggest risk is inbound (firewall problem) or internal (network design problem). A firewall vendor will never tell you to fix your internal architecture first.

A thorough VAPT report is 40–80 pages. A firewall datasheet is a marketing document. Both claim to be about security.

The scope that actually matters

When commissioning a VAPT before a security hardware purchase, specify all four of these:

External perimeter scan — what does an attacker see from the internet? Open management interfaces, exposed admin panels, unpatched services on edge devices.

Internal network scan from a guest VLAN — can a visitor or a compromised device on your guest Wi-Fi reach production systems? This is where flat networks fail.

Authenticated scan from a standard user account — what can a compromised employee endpoint reach? Most ransomware starts here.

Web application scan — if you run any internal portals, ERP, or HIS interfaces, these are common entry points that a network firewall doesn't protect.

The decision tree

If your VAPT returns zero critical perimeter findings and most issues are internal misconfiguration — you likely need a network redesign and remediation project, not a firewall upgrade. The firewall is already doing its job.

If you have management interfaces exposed to the internet, an aging UTM with no IPS subscription running, or a flat /24 with no segmentation — the firewall conversation is justified.

If you have both problems — fix the internals first. A new firewall on a flat network is a faster car with no seatbelt.

What we recommend

Run a scoped VAPT before any security hardware purchase above ₹5L. The cost (₹80K–₹1.5L depending on scope) is negligible compared to a wrong ₹12L firewall purchase. We do both — VAPT and supply-and-commission. We'll tell you honestly whether the box is actually what you need.
