Section A · Services 01–04 & 14
Every network element monitored, patched and defended.
The foundation of managed service: routers, switches, firewalls, wireless, circuits, servers and cloud workloads watched continuously, maintained on a tested cycle, and protected by layered controls from the internet edge to the access port.

Act before users feel the impact
A network operations function exists to make the difference between “the internet is down” and a circuit that failed over cleanly at three in the morning while nobody noticed. In scope: routers, switches, firewalls, wireless, SD-WAN, VPN, load balancers, ISP circuits and the UPS and environmental sensors that keep the room alive.
Keep the network healthy and fast
- Availability and performance monitoring via SNMP, flow, syslog and API telemetry
- Bandwidth, latency and capacity trending with threshold alerting before saturation
- Configuration backup, versioning and drift detection, so an unplanned change is visible
- Network documentation, topology maps and IP address management kept current
- Wireless surveys, RF tuning and coverage optimization
- ISP and circuit tracking against the carrier’s own service levels
- Scheduled health checks and preventive maintenance windows
Restore service quickly
- Alert triage, event correlation and incident ticketing with a named owner
- Remote troubleshooting and remediation across the managed estate
- Carrier, ISP and vendor escalation handled on your behalf
- Hardware failure RMA coordination and onsite dispatch
- Failover activation and service restoration
- Root-cause analysis and a corrective action plan, not just a closed ticket
You receive a live network dashboard, a monthly availability and performance report, current network documentation, and a written incident report for anything that interrupted service.
02 · Provisioning, firmware & patching
A patch cycle that is tested, staged and reversible
Patching is the control most often skipped and most often exploited. The failure mode is rarely negligence — it is that patching network equipment without a rollback plan has taken a business offline before, so it quietly stops happening. The answer is a cycle with a test stage and a rollback path, run on a schedule rather than on nerve.
Inventory & prioritize
Nothing is patched that is not first inventoried. Vendor advisories and CVE tracking set the priority, so critical, actively exploited issues move ahead of routine maintenance.
Test & approve
Pre-deployment testing with a documented rollback plan, then change approval with a full audit trail. Emergency and zero-day changes follow an expedited path that is still recorded.
Deploy & verify
Deployment in scheduled maintenance windows, then verification and patch compliance reporting — evidence the patch actually landed, and failed-patch rollback and remediation where it did not.
Provisioning
- Golden configuration templates and standards
- Zero-touch and remote provisioning of network gear
- Staging, burn-in and site activation
- Moves, adds and changes
Firmware & OS
- Firewalls, switches, access points, controllers and IoT firmware
- Windows, macOS and Linux operating systems
- Third-party applications and browsers
- Servers, hypervisors and cloud workloads
- Compensating controls and virtual patching where a fix cannot be applied yet
03 · On-premise & cloud infrastructure
One hybrid estate, wherever the workload lives
Most organizations are permanently hybrid rather than mid-migration. Servers, storage and core services are administered alongside cloud platforms as a single estate, so identity, backup and monitoring are consistent in both.
Server management
- Windows and Linux administration
- Health and performance monitoring
- Capacity planning and tuning
- File, print and application servers
Virtualization & storage
- VMware and Hyper-V hosts and clusters
- SAN, NAS and snapshot management
- High-availability design and testing
- Resource balancing and right-sizing
Directory & core services
- Active Directory and Entra ID
- DNS, DHCP and Group Policy
- Certificates and time services
- Domain health and replication checks
Public cloud
- Azure, AWS and Google Cloud administration
- Cost optimization and governance
- Landing zones and guardrails
- Cloud workload monitoring
Hybrid & migration
- Cloud and data centre migrations
- Hybrid site-to-cloud connectivity
- Workload placement planning
- Legacy system modernization
Facilities & peripherals
- UPS, power and environmental sensors
- Printers and conference room systems
- VoIP and unified communications
- Cabling and rack documentation
04 · Lifecycle & asset management
Nothing runs unsupported, unpatched or unaccounted for
Asset management is unglamorous and it is the control that quietly determines whether everything else works. You cannot patch, back up, or insure an asset you do not know you own. Every device is tracked from planning to certified destruction.
Technology roadmap and standards, budget forecasting, vendor and product selection, and a standard hardware catalog so purchasing stops being ad hoc.
Quotes, purchasing and licensing, warranty registration, asset tagging on receipt, and order and lead-time tracking.
Imaging or zero-touch setup, a standard configuration baseline, security agents and policies, then deployment and data migration.
Asset inventory and configuration database, warranty and contract tracking, software licence compliance, and moves, adds and changes.
End-of-life and end-of-support tracking, upgrade planning, staged replacement, and redeployment or trade-in to recover value.
Secure certified data destruction, chain-of-custody records, certificates of destruction and responsible e-waste recycling.
Chain-of-custody and certified destruction matter more here than in a typical IT shop. We also run digital forensics work, and the same evidentiary discipline applies to a decommissioned drive as to one under examination.
14 · Network security management
Layered controls, managed as one policy set
Edge, access and internal controls are frequently bought from three vendors, configured by three people and reviewed by nobody. Managed as one policy set and reviewed on a schedule, they stop contradicting each other.
Edge & perimeter
- Next-generation firewall management
- Intrusion detection and prevention tuning
- Web application firewall and DDoS protection
- Geo-IP and threat-feed blocking
- Firewall rule audits and cleanup
Secure access
- VPN and zero trust network access
- Secure access service edge and security service edge
- Secure web gateway and DNS filtering
- Cloud access security broker
- Remote and branch user protection
Internal network
- Segmentation and microsegmentation
- Network access control and 802.1X
- Secure Wi-Fi and rogue access point detection
- Network detection and response
- Certificate and PKI management
- IoT and OT device isolation
Reactive work in this zone is measured in minutes: emergency rule changes, threat blocking and quarantine, firewall failover and recovery, and security event investigation escalated to our security operations centre.
Hardening baselines follow the CIS Critical Security Controls rather than vendor defaults. Framework mapping follows NIST CSF 2.0.
Evidence
What you receive, and why it matters
The difference between a managed service and an invoice is evidence. Each of the services on this page produces an artefact you can hand to an auditor, an insurer, a customer running due diligence, or the next provider if you ever leave us. That last point is deliberate: documentation that only works while we hold the contract is a lock-in mechanism, not a deliverable.
Network documentation
Current topology maps, IP address management, circuit and carrier details, and device inventory with firmware levels. Maintained continuously rather than rebuilt annually, because documentation written once is wrong within a quarter.
Patch compliance reporting
Which devices are current, which are behind, which are waiting on a maintenance window and which cannot be patched at all and are therefore running compensating controls. The exceptions list is the useful part.
Availability and performance
Monthly reporting on uptime, circuit performance against the carrier’s own commitments, capacity trending, and the incidents that interrupted service with their root cause and corrective actions.
Firewall rule audit
A periodic review of what the rule base actually permits, including rules that are unused, shadowed, overly permissive or left behind by a project that ended two years ago. Rule bases accumulate; they are rarely pruned.
Asset and lifecycle register
Every device with its warranty status, support dates, location and owner, plus the refresh plan and budget forecast that comes out of it.
Change and incident record
An audit trail of every approved change and every incident, which is what turns a disputed outage into a documented sequence of events.
Reporting cadence, escalation contacts and the definition of each incident priority are set in your service agreement. We publish the structure here and the specifics there, because a response target that has not been matched to your environment, your coverage hours and your tolerance for downtime is a number chosen for a brochure rather than a commitment we can stand behind.
Questions we hear first
About network and infrastructure management
Do you replace our existing firewall and switches?
Only where the equipment is genuinely unfit or unsupported, and we will show you the reasoning. We are vendor-neutral and would rather manage hardware you already paid for. What we do insist on is that every managed device is supported by its manufacturer, because an appliance past end-of-support cannot be patched and becomes the weakest point in the estate.
Will patching take us offline?
Patching carries risk, which is exactly why it is run as a six-step cycle with a test stage, an approval record and a rollback plan rather than applied on sight. Routine work happens in agreed maintenance windows. Out-of-band critical patching is a separate, expedited path that we will discuss with you before invoking.
What about our older equipment that cannot be patched?
It gets compensating controls — segmentation, restricted access paths and closer monitoring — and it goes on the refresh plan with a date. Isolating unsupported equipment is a legitimate interim measure; leaving it on the flat network is not.
Can you cover multiple sites and remote workers?
Yes. Multi-site and multi-shift coverage is the usual reason organizations move to 24/7 rather than 8/5. Remote and branch users are covered through secure access rather than by assuming everyone sits behind the office firewall.
Start with an assessment, not a quote
We baseline the current state first — asset discovery, network and security assessment, prioritized findings — then propose a plan sized to what we actually found.
