Even modern IT still has legacy limitations No organization plans to build legacy systems.
They emerge organically. Even fast-moving startups find that after years of rapid scaling, they’ve inherited outdated tools, unpatched components, or brittle integrations. A McKinsey study found that 20–40% of technology estate value is trapped in tech debt, even among digital leaders.
No organization plans to build legacy systems. They emerge organically. Even fast-moving startups find that after years of rapid scaling, they’ve inherited outdated tools, unpatched components, or brittle integrations. A McKinsey study found that 20–40% of technology estate value is trapped in tech debt, even among digital leaders.
Common hidden legacies include:
- Aging middleware: Modern UIs often hide outdated integration layers that can’t support real-time analytics.
- Manual processes: Automated front ends still rely on manual data re-entry, slowing performance and introducing errors.
- Unscalable databases: Old databases limit modern app performance, creating recurring “next year’s problem.”
- Shadow apps: Departmental tools like Access databases or custom CRMs that fall out of support and become security risks.
Gartner predicts that this year, 85% of enterprises will face operational failures due to hidden legacy issues within hybrid cloud infrastructure.
And nearly 70% of IT leaders say legacy systems prevent them from adopting modern tech like AI. In other words, legacy doesn’t just slow you down; it can block innovation and open the door to cyber threats.
