Next-Generation Firewall supply, deployment and support
CyberGrid helps enterprises choose, deploy, migrate and support next-generation firewalls (NGFW). We work across Palo Alto Networks, Fortinet, Sophos, Cisco, Check Point and SonicWall, and provide managed support so the firewall keeps protecting you after go-live.

What Next-Generation Firewall does
A next-generation firewall inspects traffic at the application layer, not just by port and protocol. It combines deep packet inspection, application control, intrusion prevention and threat intelligence in one control point.
It protects the data center edge, branch offices and cloud workloads, and enforces a consistent policy for users wherever they connect from.
What CyberGrid delivers
- Requirement and sizing assessment based on throughput, users, sites and security features needed
- Vendor shortlisting and licence guidance across the platforms we support
- Design, configuration, policy build and cut-over
- Migration from your existing firewall with rule clean-up and a rollback plan
- Ongoing support, health checks and policy reviews
Who it is for
- Enterprises replacing an end-of-life or legacy port-based firewall
- Multi-branch organisations that need consistent policy across sites
- Regulated businesses that must show perimeter controls to auditors
We serve organisations across India and support customers globally, with offices in Bangalore, Hyderabad, Chennai and Trivandrum.
How we deliver Next-Generation Firewall
1. Discovery and requirements
We map your sites, links, user counts, applications, remote-access needs and the security features you want enabled together, such as application control, IPS, SSL inspection and sandboxing. We also record the compliance obligations the firewall has to help you evidence.
2. Sizing and platform selection
Appliances are sized against threat-prevention throughput, concurrent sessions and growth, not the headline figure on a datasheet. We shortlist suitable models across the vendors we work with and set out hardware, subscription and support cost side by side.
3. Design and policy build
We design zones, routing, high availability and logging, then build the rule base around applications and identities instead of broad port ranges. For a replacement project we start from your existing rules and remove unused, shadowed and duplicate entries first.
4. Testing and cut-over
Policy is tested before go-live, and the cut-over is scheduled in an agreed window with a rollback plan. Traffic is monitored closely after the switch so problems are caught while the change is still fresh.
5. Handover and ongoing support
We document the design and policy, brief your team, and stay on for firmware and signature updates, change requests, health checks and periodic rule reviews under a support agreement.
What to look for when choosing
Throughput with security features on
Vendors publish firewall-only numbers and lower figures with threat prevention and SSL inspection enabled. Size against the lower figure, or the firewall becomes the bottleneck the first time inspection is turned on.
Management and operations
A central management console, clear logging and a rule base your team can actually read matter as much as raw performance. Consider who will run the firewall day to day and what skills they have.
Licensing over the full term
Threat prevention, URL filtering, sandboxing and support are usually separate subscriptions that renew. Compare three- and five-year cost, not only the appliance price.
Fit with the rest of your network
Existing switching, SD-WAN, endpoint and identity tools influence which platform integrates most cleanly. Mixing vendors is workable but should be a deliberate choice.
Compliance alignment
A properly configured firewall supports perimeter and segmentation controls expected under frameworks such as ISO 27001, PCI DSS and RBI cyber security guidance, and its logs help meet CERT-In incident reporting expectations. We map firewall policy and logging to the controls your auditors will ask about.
Common scenarios
Replacing an end-of-life firewall
The old appliance is out of support and its rule base has grown for years. We clean the rules, rebuild policy on a current platform and cut over in a planned window with rollback.
Connecting new branch offices
Each new site needs the same policy as head office. We standardise templates so a branch firewall can be deployed and managed consistently.
Preparing for an audit
Auditors ask for evidence of segmentation, logging and change control. We align firewall policy, log retention and change records to the controls being assessed.
Mistakes to avoid
- Buying on datasheet throughput. Figures with security features off overstate real capacity. Size for threat-prevention throughput.
- Migrating rules without review. Copying an old rule base across carries over risky, unused and duplicate rules. Review before you migrate.
- Ignoring logging. A firewall nobody monitors only records what went wrong. Send logs to a system that raises alerts.

Frequently asked questions
Palo Alto vs Fortinet: which firewall is right for us?
Both are strong enterprise platforms. The right choice depends on throughput, the features you need turned on (such as SSL inspection and IPS together), your team’s skills, existing network stack and budget. We compare them against your actual requirements rather than recommending one by default.
How do we size a firewall for our organisation?
Sizing is driven by real throughput with security features enabled, concurrent sessions, number of users and sites, and expected growth. Datasheet maximums are usually measured with features off, so we size against threat-prevention throughput.
How do firewall pricing and licensing work?
Cost typically has two parts: the hardware or virtual appliance, and subscription licences for security services such as threat prevention, URL filtering and support. We lay out both for each shortlisted option so the multi-year cost is clear.
How long does a firewall deployment take?
It depends on the number of sites, rule-base complexity and whether it is a new build or a migration. A discovery call lets us give a realistic timeline for your environment.
Can you migrate us from our current firewall?
Yes. We review the existing rule base, remove unused and duplicate rules, rebuild policy on the new platform, test, and cut over with a rollback plan to limit downtime.
What support do you provide after deployment?
Support covers incident response for firewall issues, firmware and signature updates, change requests and periodic policy reviews. Response terms are agreed in the support agreement.
Do you support high-availability firewall pairs?
Yes. For sites where downtime is costly we design active-passive or active-active pairs, with tested failover and a clear procedure for upgrades so the pair is not left in a degraded state.
Which firewall vendors do you work with?
Palo Alto Networks, Fortinet, Sophos, Cisco, Check Point and SonicWall. We recommend the platform that fits your requirements, skills and budget, and we are open about trade-offs between them.
