Firewall and network security, from design to AMC.

Firewall and network security for Indian enterprises: next-generation firewall design and deployment, managed firewall, rule-base reviews and AMC on Fortinet, Palo Alto Networks and Sophos. NetScale designs the perimeter and segmentation with the network, runs it and keeps the rule base and the support contract current under one owner.

What it is

Firewall and Network Security

Firewall and network security covers the perimeter and the segments inside the network: next-generation firewalls, their rule base and the support contracts behind them.

A next-generation firewall (NGFW) filters traffic by application and user as well as by address and port. NetScale designs it with the network, reviews the rule base on a schedule and keeps the AMC and OEM renewals under one owner.

Web, browser and SaaS controls for every user sit under Secure access.

What we do.

  1. 01

    NGFW design and deployment

    Next-generation firewall architecture, high availability, segmentation and policy design, deployed in phases with testing at each stage.

  2. 02

    Managed firewall and rule reviews

    Monitoring in the support window agreed in writing, change management, periodic rule-base health checks and clean-up of unused and over-permissive rules.

  3. 03

    Firewall log retention

    Firewall logs kept in a central store in India for 180 days, with clocks synchronised to NIC or NPL.

  4. 04

    Firewall AMC and OEM support

    Annual maintenance and OEM renewals, firmware and signature updates, configuration backup and direct escalation into the vendor’s support organisation, under one owner, with the support window and response times in writing.

How an engagement runs.

Each phase adds a layer to the same three sites.

A plan of three sites on one network, each site supported by its own vendor. Assess marks: high availability; logging gaps. Deliver adds: firewalls deployed; tested before cut-over. Operate adds: rule reviews on a schedule; renewals under one contract.

You can stop at any phase boundary. The assessment is free, and each phase is priced in writing before it starts.How we engage

Firewall and network security

India specifics and cost.

India specifics

  • CERT-In

    Under the Directions of April 2022, firewall logs are kept for 180 days within India, with clocks synchronised to NIC or NPL. The incident path is documented, so the 6-hour reporting duty can be met.

  • DPDP

    Perimeter and segmentation controls form part of the reasonable security safeguards the DPDP Rules require. Legal interpretation stays with your counsel.

  • Procurement

    The AMC scope of work is written in plain terms, with HSN and SAC codes supplied for purchase orders.

What drives the cost

  1. 01

    Throughput, site count and whether high availability is required at each site.

  2. 02

    Subscription bundles (threat prevention, URL filtering, sandboxing) and their terms.

  3. 03

    Managed firewall scope: monitoring only, or monitoring with change management and rule reviews.

  4. 04

    AMC level and whether spares or an on-site engineer are included.

Questions buyers ask about this.

What should a firewall AMC scope of work include?

Six things: the support window and response times in writing, OEM renewal management, firmware and signature updates, periodic rule-base review, configuration backup and the escalation path into the OEM. We write the scope so procurement can compare it line by line, with HSN and SAC codes for the purchase order.

How is firewall AMC cost calculated in India?

Mostly by model and throughput, the OEM subscription bundle, the number of sites and the support level. The free health check gives you one written view of what you have and what each renewal costs, before you commit to anything.

Do you work with the firewalls we already have?

Yes. We review the rule base and support status first and keep what is sound. Replacements are planned only where the hardware is past support or the design cannot deliver segmentation. Existing equipment stays where it meets the design; you are not asked to replace everything.

Book a firewall health check.

It costs nothing and commits you to nothing. You get a written list of where your IT environment is exposed, and your team can act on it with or without us.

What we put in writing

  1. The written findings are yours whether we ever work together or not.
  2. Each phase is fixed-scope and signed off separately.
  3. You can stop at any phase boundary.
  4. Runbooks, configurations and credentials are yours.
