Proactive Reliability

Prevent Costly Downtime Before It Impacts Your Paying Customers

Production applications degrade over time due to unpatched security vulnerabilities, third-party API deprecations, bloated database indexes, and framework obsolescence. Our dedicated maintenance engineers actively monitor application health, apply security updates, and fix defects rapidly under established SLAs.

Proactive Monitoring

24/7 uptime checks, CPU/memory threshold alerts, and instant incident escalation.

Security Hardening

Routine dependency security updates, vulnerability scanning, and automated backups.

Got Questions?

Software Maintenance FAQs

Clear terms regarding SLAs, onboarding legacy code, and incident response.

Can you maintain software that was built by another agency?

Yes. We frequently onboard existing codebases from previous agencies or past in-house developers. We begin with a structured 1-week code and infrastructure audit, document existing technical debt, set up observability tools, and assume full operational maintenance responsibility.

What SLA response times do you guarantee?

Under our standard enterprise maintenance agreement, Critical (Severity 1) outages receive an initial response within 1 hour and immediate developer assignment. General defects (Severity 2 & 3) receive a response within 4 business hours.
