The Problem

Your Legacy Systems Are Costing More Than You Think

Most organizations still depend on legacy software for critical operations. While these systems keep the lights on, they quietly drain budgets, create security risks, and block your ability to compete.

60–80%
Budget Drain

of IT budgets are consumed by maintaining legacy systems — leaving less than 20% for growth and innovation.

$4.88M
Breach Cost

average data breach cost. Legacy systems with unpatched dependencies and outdated auth are a leading attack vector.

$300K+
Downtime Cost

per hour of unplanned downtime. Legacy system failures don't just cost money — they cost customers and reputation.

30%
Slower Teams

Teams burdened with high technical debt are slower. Developers spend a third of their time maintaining legacy code instead of building.

Shrinking
Talent Pool

Legacy system specialists are aging out of the workforce, and fewer engineers are learning older technologies. The expertise to maintain your systems is getting harder to find every year.

High
Failure Rate

Most large-scale modernization projects fail without proper methodology and expertise. The stakes are high — and the cost of getting it wrong is enormous.

Technical debt costs the U.S. economy $2.41 trillion annually.

The question isn't whether to modernize — it's whether you can afford not to.

From Assessment to Modernized Code

Watch our AI-assisted assessment analyze a legacy Java class, surface critical findings, then modernize it using your choice of stack.
