Sietch watches how a program behaves, and turns that into answers you can act on. Whether you're moving software or recovering it, the behavior is the ground truth.
When the source is lost, abandoned, or locked behind a vendor, Sietch reconstructs readable, recompilable code from how the binary behaves. No disassembly, no decompilation. Own it, audit it, modernize it, port it. The software becomes yours again.
Move from CentOS to RHEL, bump a runtime, change architectures, and the risk is always the same: does it still do exactly what it did before? Sietch runs its behavioral harness against your binary on both sides of the migration and reports every divergence, down to the edge case. Sign off on migrations with evidence, not hope.
