Pentest remediation run
by .NET specialists

Pentest reports against .NET applications and Umbraco environments have been our work for years, spanning Azure App Service, Azure Container Apps, GreenStack and traditional on-premise IIS. The same families of finding come round repeatedly: absent security headers, weak TLS, version disclosure in HTTP responses, backoffice paths reachable from the public internet, and credentials stored where Key Vault should have held them three architecture reviews ago. Producing the report is the straightforward part; fixing each finding without breaking an application that must stay running is not.

Work we handle routinely: HTTP security header hardening including HSTS, CSP and modern referrer and permissions policies, TLS brought to current best practice, removal of version disclosure across IIS, .NET and Umbraco response surfaces, OWASP Top 10 remediation in .NET code, Azure subscription hardening across network security groups, private endpoints, Key Vault integration and Defender for Cloud findings, on-premise Windows and IIS hardening, and triage of a full report into risk-prioritised items with named owners and target dates. For Umbraco: backoffice access restriction, member and user account hardening, file upload validation, and package-level CVE work on older versions.

A report with no in-house capacity behind it, an ISO 27001 or SOC 2 assessment requiring evidence of remediation, or continuous hardening between formal tests rather than an annual scramble: we triage, fix and retest alongside your assessor.
