Pentest remediation run
by .NET specialists

We've been remediating pentest reports against .NET applications and Umbraco environments for years, across Azure App Service, Azure Container Apps, GreenStack, and traditional on-prem IIS. That means we've seen the same families of findings turn up again and again: missing security headers, weak TLS configurations, version disclosure in HTTP responses, backoffice paths reachable from the public internet, and stored credentials that should have been in Key Vault three architecture reviews ago. The report itself is the easy part. The work is in fixing each finding without breaking the application that needs to keep running while you do it.

The work we run regularly: HTTP security header hardening including HSTS, CSP, and the modern referrer and permissions policies, TLS configuration 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 including network security groups, private endpoints, Key Vault integration, and Defender for Cloud findings, on-prem Windows and IIS hardening, and the structured triage of a full pentest report into risk-prioritised work items with named owners and target dates. For Umbraco specifically we handle backoffice access restrictions, member and user account hardening, file upload validation, and the package-level CVE work that older Umbraco versions accumulate over time as standard.

Whether you've just received a report you don't have the in-house capacity to action, you're preparing for an ISO 27001 or SOC 2 assessment that requires evidence of remediation, or you want continuous hardening between formal pentests instead of an annual fire drill, we'll triage it, fix it, and retest it with your assessor.
