Retire the perimeter. Verify everything.
“Inside the network” is not a security boundary. B5 Secure modernizes legacy and cloud estates to a Never Trust posture — assume breach, verify every request, grant least privilege — without a rip-and-replace, and on .NET 10.
The challenge
Most modernization stalls because zero trust is treated as a product to buy rather than an enforcement model to adopt. Teams add an identity provider at the edge but still trust internal calls, hard-code exemptions, and authorize by role instead of by data. The result is a perimeter with extra steps.
The Never Trust answer
The seven NIST zero-trust tenets become enforced defaults: every request authenticated and authorized through one pipeline, least privilege scoped to action and record, continuous monitoring, and a secured environment — old surfaces and new running behind a single contract.
Modernize without rebuilding
Co-host, don’t rewrite
ASP.NET Core minimal APIs and GraphQL run alongside co-hosted ServiceStack on .NET 10, so one security contract governs legacy and new surfaces during the migration — not after it.
Verify every request
Authentication and authorization move out of per-controller code into the pipeline. Every caller — human, service, job, agent — is verified the same way, with no internal exemptions.
Least privilege, by data
Replace coarse role checks with activity-data authorization: permits scoped to the action and the specific record and fields, derived by convention so they can’t drift.
Adaptive enforcement & CAE
A static IP allow-list as the strict core, layered with an adaptive identity firewall and Continuous Access Evaluation that revokes sessions in near-real-time as risk changes.
Make zero trust the default, not a project.
Adopt the Never Trust pipeline across your estate — on the platform that secures $15B+ in custody.
