Security Expertise
Deep-level Windows security engineering — from smart card drivers to Active Directory protocol internals.
Active Directory Replication
We are the worldwide experts on AD replication techniques including DCSync and DCShadow. Whether you need to replicate credential data in trust-less environments or harden against such attacks, we have deep hands-on experience.
Smart Card Driver Development
CSP, OpenSC driver, or Windows minidriver — delivered at fixed price with full compliance with Microsoft's test suite and optional auto-deployment via Microsoft Update.
Windows Authentication Hooks
Credential Providers, GINA DLLs, SSP/AP packages, Kernel SSPs, NegoEx extensions, password filters, ISAPI filters — we build the deepest authentication integrations Windows supports.
Integrating smart cards — especially EIDs compliant with ISO 7816-15 / PKCS#15 — is difficult because most vendors ship drivers with subtle, hard-to-reproduce bugs. Common failures include user-context caching, incompatibility with system accounts, silent-context breakage, broken container enumeration, and Microsoft Update incompatibility.
Developing a CSP, an OpenSC driver, or a minidriver requires specialized skills — these components can be loaded into Windows security kernels, and errors are often silent and difficult to diagnose.
My Smart Logon has built numerous production smart card drivers — including the OpenPGP minidriver and the EIDVirtual minidriver — and has contributed patches to the OpenSC project.
Fixed-price packages available. We offer competitive, high-quality smart card driver development — fully compliant with Microsoft tests and ready for Microsoft Update auto-deployment. Contact us to discuss your project.
Common Sign-On to SSO
We build web server plugins — including IIS ISAPI filters — that rewrite NTLM authentication messages on the fly, bridging untrusted corporate domains seamlessly.
Password synchronization
Custom password filter libraries running on domain controllers — synchronizing passwords across Windows, Unix, and custom identity stores, including direct SAM database access.
Custom authentication protocols
Credential Providers, GINA DLLs, SSP/APs, Kernel SSPs, NegoEx packages — for any device or protocol, including smart card and hardware token integration. See EIDAuthenticate as a proof of our depth.
