Managed Firewall Services
As a leading national UK provider, NetMonkeys delivers Next-Generation Firewall (NGFW) deployment and continuous perimeter monitoring. We protect corporate networks, multi-site traffic loops, and cloud entry channels from advanced edge exploitation.
What is a managed firewall?
A managed firewall service is an enterprise cybersecurity solution where an outsourced technical partner assumes complete operational accountability for a business's network perimeter. Rather than tasking internal, non-specialist resources with the oversight of complex hardware frameworks, a dedicated managed security provider configures, monitors, and optimizes Next-Generation Firewalls (NGFW) to identify internal vulnerabilities and block malicious vectors.
- Rule Lifecycle Management: Constant ruleset audits to drop legacy pathways and close inactive open ports.
- Deep Packet Inspection (DPI): Examining full payload data blocks in transit to trap sophisticated modern malware layers.
- Zero-Day Patching loops: Immediate out-of-hours security firmware updates to protect physical endpoints from emerging exploits.
- Unified VPN Management: Building and enforcing encrypted Client-to-Site and Site-to-Site encrypted IPsec connection nodes.

Why standard IT isn't enough for network security
Purchasing an expensive firewall hardware appliance is only step one. A firewall is only as effective as the engineers configuring its rulesets and monitoring its traffic logs. Without active management, hardware quickly falls out of date, leaving critical gaps in your perimeter.
Our proactive gateway defence takes the burden off your internal team. Our certified engineers handle the daily administration, from deploying rapid zero-day patches to managing complex site-to-site VPN tunnels, ensuring your perimeter security posture is always airtight.
Unified Threat Management (UTM)
We deploy Next-Gen Firewalls that go beyond port blocking, integrating application control, web filtering, and antivirus at the gateway.
24/7 Intrusion Prevention
Our solution includes active Intrusion Detection and Prevention Systems (IDS/IPS) to block malicious traffic automatically.
Cyber Essentials Ready
We configure your network rules explicitly to pass the strict boundary requirements of Cyber Essentials Plus.
Our Comprehensive Firewall defense Solutions
We provide end-to-end administration of your network perimeter. Here is how our engineering team delivers your network edge solution.
High-Availability (HA) Configuration
We deploy active-passive or active-active appliance clusters. If your primary hardware appliance suffers a catastrophic failure, traffic automatically fails over to the secondary unit, ensuring zero downtime for your business operations.
Custom Rule & Policy Configuration
Out-of-the-box configurations are rarely secure. We build custom rulesets that allow your legitimate business traffic to flow while aggressively blocking unauthorised access attempts, enforcing the principle of least privilege.
Secure VPN Management
Whether connecting remote workers safely via Client VPNs or bridging multiple office locations with secure Site-to-Site IPsec tunnels, we manage all encryption and access protocols natively through our security services.
Firmware Patching & Updates
We perform critical firmware updates and security patching out-of-hours to prevent operational downtime, completely removing the risk of unpatched vulnerabilities.
Real-Time Threat Monitoring
Our proactive network monitoring detects unusual traffic spikes, DDoS attempts, and malware signatures, allowing our Security Operations Centre to neutralise threats before they breach your network.
Why standard routers leave your data exposed
| Security Feature | NetMonkeys Gateway Defense | Standard Office Router / Basic IT |
|---|---|---|
| Traffic Inspection | Deep Packet Inspection (DPI) analyses encrypted data streams for hidden malware. | Only checks IP headers and port numbers, completely blind to hidden payloads. |
| Maintenance | Proactive zero-day patching and firmware updates applied automatically out-of-hours. | Manual patching that is often forgotten, leaving known exploits unpatched for months. |
| Intrusion Prevention | Active IPS/IDS terminates malicious connections and brute-force attacks in real-time. | No active prevention; relies solely on endpoint antivirus after a breach occurs. |
| Compliance | Strict rule auditing and logging to guarantee Cyber Essentials Plus compliance. | No granular access logs, failing modern PI insurance and ISO security audits. |

What is included in your managed firewall services UK package?
Our service encompasses hardware provisioning, initial architecture design, custom rule configuration, 24/7 SOC monitoring for intrusions, scheduled firmware updates, Site-to-Site VPN management, and hardware replacement Production SLAs.
Can a network edge solution support remote workers?
Yes. A correctly configured Next-Gen Firewall acts as the secure gateway for your remote team. We configure encrypted Client VPN tunnels and Zero-Trust access rules so remote staff can securely access internal servers without exposing your network to public internet threats.
Why do I need an expert managed firewall service provider?
Buying an advanced hardware device is useless if it is misconfigured. In 90% of breaches involving firewalls, the failure is due to a misconfigured rule (like leaving RDP port 3389 open), not a hardware failure. Our engineers guarantee your policies are airtight and strictly audited.
Are firmware updates included in the firewall managed service?
Absolutely. Unpatched firewalls are a leading cause of network breaches. Our service includes proactive tracking and deployment of all critical vendor firmware updates, typically applied out-of-hours to ensure zero disruption to your business.
