Next Generation Firewall Installation & Management in London

A standard router firewall stops almost nothing a modern attacker throws at it. Our next generation firewalls (NGFW) for London businesses add deep packet inspection, application awareness, SSL inspection and intrusion prevention, then we manage them properly so they stay effective.

An unmanaged firewall is a false sense of security

Most firewall breaches happen because rules were never reviewed, firmware was never patched, or SSL inspection was quietly switched off to stop a website breaking. We manage your next generation firewall as an ongoing service, not a one-off install, so it keeps doing its job.

The Difference

What Makes a Next Generation Firewall Different

A next generation firewall does far more than block ports. Here's what changes when you upgrade from a standard firewall.

Application Awareness

Identifies exactly which application is generating traffic, not just the port it's using, so risky apps can be blocked without breaking the ones you rely on.

SSL/TLS Inspection

Decrypts and inspects encrypted HTTPS traffic for threats before re-encrypting it, closing the blind spot where most malware now hides.

Intrusion Prevention (IPS)

Actively scans for known attack signatures and blocks them in real time, rather than simply logging suspicious traffic after the fact.

Managed, Not Just Installed

We monitor logs, update threat signatures, review rules and apply firmware patches as part of an ongoing managed security service.

Multi-Vendor Expertise

We Install and Manage Firewalls From Every Major Vendor

Frequently asked questions

A traditional firewall filters traffic based on IP address and port number. A next-generation firewall adds deep packet inspection, application awareness (identifying what application is generating traffic, not just the port), SSL/TLS inspection of encrypted traffic, intrusion prevention (IPS), and advanced threat detection. NGFWs catch threats that easily bypass traditional firewalls.

Speedster IT installs and manages next-generation firewalls from WatchGuard, Cisco Meraki (MX series), Fortinet FortiGate, and Palo Alto Networks. We recommend the most appropriate platform based on your business size, throughput requirements, compliance needs, and budget.

Yes. Even small businesses are targeted by automated attacks scanning for weak firewalls. A NGFW provides intrusion prevention, application control, and encrypted traffic inspection that a standard broadband router simply cannot provide. The cost starts from around £500–£1,000 per year including hardware and subscription — well justified by the protection it provides.

Speedster IT manages your firewall as part of a managed security service — monitoring logs, updating threat intelligence signatures, reviewing and adjusting rules, and applying firmware updates. Unmanaged firewalls are frequently misconfigured or left unpatched, creating the vulnerabilities they are supposed to prevent.

SSL inspection decrypts and inspects HTTPS traffic for threats before re-encrypting it. Without it, malware delivered over HTTPS (the majority of web traffic) is invisible to the firewall. Speedster IT enables SSL inspection with appropriate certificate management to ensure browsers trust the inspection process, without breaking web applications.

Yes. Speedster IT installs and manages next generation firewalls for businesses across London and the wider UK, with WatchGuard Gold Partner engineers based in Whitechapel, East London, available for on-site visits when needed.
