Sourcegraph BlogToolsDetection in one repo isn't a security posture A finding in one repo is a fact. A security posture means knowing whether that same problem exists everywhere else, and fixing it before it spreads.

Sourcegraph BlogToolsWhy your migration tools are failing your engineers The bottleneck in most large-scale migrations is not the engineers or the plan. It is that the tools cannot see the whole codebase.
