SLA-Based Technical Support

Support That Shows Up On Time. And Knows What It's Doing.

Senior engineers on clear SLAs, owning incidents and fixes - so "we're looking into it" isn't the update for three days straight.

Make Downtime Predictable - With an SLA That Drives Real Outcomes

When live support is informal or fragmented, something breaks: incidents linger, small faults repeat, and critical knowledge lives in a handful of stressed people. The cost shows up fast - revenue leakage, delayed delivery, growing security exposure, and stakeholder confidence that drops every time a "quick fix" turns into another outage.

SLA-based support puts control back where it belongs: clear targets, clear accountability, and a structured way to keep systems stable in the real world. The right model is never one-size-fits-all - it needs to fit the way services run, the integrations they depend on, and the risk profile behind each application. The sooner this is formalised, the sooner outages stop driving the roadmap.

Here's what gets delivered through a clearly defined SLA:

  • Guaranteed response targets with tiered coverage windows and escalation paths
  • Disciplined incident triage and recovery to reduce time-to-restore and minimise impact
  • Bug fixing with root-cause follow-through to prevent repeat failures
  • Security and dependency patching aligned to change controls and release processes
  • Planned maintenance and stabilisation work to keep systems supportable over time
  • Transparent reporting and service metrics so performance is visible, measurable, and auditable

If uptime matters, make it enforceable - agree the rules, define the scope, and tie delivery to senior engineering ownership, then take the next step toward measurable reliability and Build a Predictable Support Model.

Use Cases to Cut Incident Impact With SLA-Backed Support

Each use case is designed to reduce downtime cost, operational risk, and the drag caused by reactive support.

Production Incident Response & Stabilisation
Rapid triage, containment, restoration, and follow-through to stop the same outages repeating.

Support Tiers Built Around How You Operate

Not every system carries the same business risk, and support should reflect that. Our tiers align response targets, coverage windows, and communication routes to the role each application plays - while keeping scope, bug-fix expectations, and patching responsibilities clear.

Each tier includes onboarding to confirm what's covered, how incidents are logged, and how maintenance is scheduled. You'll also receive transparent reporting so you can track performance and make informed decisions over time.

Tier 1 Tier 2 Tier 3
Response Time 1 hour 12 hours 1 working day
Coverage 24/7 Mon to Fri 2 Mon to Fri 2
Support Channels All channels All channels Email only
Uptime Guarantee 3 Yes - -
