SLAs & incident response

We define clear Service Level Agreements (SLAs) based on support tier, ensuring issues are addressed within agreed timelines. Response times vary by tier: Tier 1 (6 hour response), Tier 2 (3 hour response), and Tier 3 (custom SLA options).

Within each tier, we prioritize issues by severity to ensure critical problems get immediate attention while lower-priority items are handled systematically.

Our 24×7 monitoring and on-call coverage means we often detect and resolve issues before they impact your users. Proactive support that prevents downtime and maintains user trust.

Success metrics we track

We don't just fix issues. We continuously measure and improve your application's health using industry-standard metrics:

  • Uptime: 99.9%+ availability targets
  • Apdex Score: Application Performance Index tracking user satisfaction
  • Error Budgets: Proactive error tracking and remediation
  • Response Times: P50, P95, P99 latency monitoring
  • Security Posture: Vulnerability scanning and patch compliance
  • Code Health: Technical debt tracking and refactoring progress

Frequently asked questions

Common questions about web application support and maintenance services.

Ongoing web application support and maintenance reduces three major risks: unplanned downtime, security incidents, and slow performance that quietly erodes revenue. Instead of reacting to outages, we continuously monitor, patch, and optimize your web apps so they stay fast, secure, and reliable. Even as traffic, data, and complexity grow.

Traditional break-fix or MSP models are optimized for ticket throughput. Our web application support service is product-driven: we combine 24×7 monitoring, proactive maintenance, and continuous improvements tied to business metrics like uptime, Apdex, conversion, and error budgets. You get direct access to senior engineers and a roadmap for improving the application, not just keeping the lights on.

Yes. Many clients come to us with web applications built by other agencies or internal teams. We start with a structured takeover that includes architecture and code review, dependency and security audit, performance baseline, and runbook creation. That gives us enough context to stabilize, support, and then gradually improve your web application without forcing a risky rewrite.

We support modern frontend frameworks (React, Next.js, Angular, Vue/Nuxt, Svelte), backend stacks (Node.js/Express/Nest,.NET, Java/Spring, Python/Django/Flask/FastAPI, Ruby on Rails, PHP/Laravel), and common databases (PostgreSQL, MySQL, SQL Server, MongoDB, Redis). On the infrastructure side we work across AWS, Azure, and Google Cloud so we can support both your web application and the cloud environment it runs on.

We classify issues by business impact. Critical outage, major degradation, minor bug, or enhancement and align each web application support tier to specific response and resolution targets. Higher tiers include faster response times, broader monitoring coverage, and a larger allocation for improvements, so you can treat web app maintenance as a lever for product evolution, not just an insurance policy.

We report on metrics that matter to leaders: avoided downtime, incident trends, performance improvements, security posture, and impact on funnel conversion or user satisfaction. Over time, those reports make it clear that structured web application maintenance reduces risk, protects revenue, and creates space for continuous improvement rather than perpetual firefighting.

Web application maintenance is the ongoing practice of keeping your web apps secure, up to date, and performant after launch. It includes monitoring, security patches, dependency and framework upgrades, bug fixes, and small improvements so your application keeps pace with browsers, devices, and user expectations instead of drifting out of date.

A Service Level Agreement (SLA) defines how quickly your support team responds to and resolves different types of issues. Clear SLAs for web application support turn vague promises into concrete expectations, so you know how critical outages, major bugs, and minor issues will be handled and you can explain that reliability to your customers and stakeholders with confidence.
