slower product releases occur when teams are constrained by tightly coupled, aging architectures and brittle codebases.

70%

of IT budgets are consumed by maintaining legacy systems, leaving little room for innovation and growth across teams.

3x

higher security incidents are reported in outdated systems due to unsupported frameworks and unpatched dependencies.
