Technical Hardening & Remediation
Full Remediation Package
Hands-on engineering execution that closes audit findings, patches technical vulnerabilities, and hardens your environment against real-world attack vectors.
Recommended For
- Organisations that received an audit gap report, VAPT findings, or insurance renewal requirement they lack internal capacity to implement
- IT teams seeking hands-on engineering assistance to deploy Conditional Access MFA, WDAC/AppLocker, and Privileged Access Management
- Enterprises requiring immediate hardening following a security incident or failed procurement compliance review
Service Overview
Turn Audit Findings into Active Technical Safeguards
Identifying security vulnerabilities is only half the battle. Many Australian organisations possess detailed penetration testing reports or Essential Eight gap assessments, but struggle to implement complex technical controls — such as Application Whitelisting, Privileged Access Management (PAM), and Entra ID Conditional Access — without disrupting business operations.
Whitesec AU's Full Remediation Package provides experienced security engineers to execute the hands-on technical work. We configure, test, and deploy hardening policies directly into your Active Directory, cloud environments, and endpoint management systems, delivering verified risk reduction.
Zero Downtime
Staged engineering execution ensuring production systems remain operational throughout hardening deployment.
Regulatory & Standards Alignment
ACSC Essential Eight ML1 - ML3 Enforcement
Turn gaps into implemented technical controls across identity, endpoint, application, and backup controls.
ISO/IEC 27001 Annex A Technical Controls
Implement technical safeguards mandated by ISO 27001 Information Security Management Systems.
NIST SP 800-53 / CIS Benchmarks
Hardening configurations applied to Active Directory, Entra ID, Windows Server, and cloud tenants.
Executive Business Value & Outcomes
Audit Finding Closure
Convert penetration testing and compliance audit findings into defensible, verified security controls.
Phishing-Resistant Identity
Deploy Entra ID Conditional Access, FIDO2 hardware tokens, and block legacy authentication protocols.
Application Whitelisting Deployment
Configure AppLocker or Windows Defender Application Control (WDAC) to prevent unauthorized binary execution.
Immutable Ransomware Backups
Implement immutable, air-gapped backup storage policies that guarantee operational recovery post-attack.
Re-Test & Certification Support
Provide independent re-testing and updated verification reports ready for auditors and insurers.
Internal Team Knowledge Transfer
Train your internal IT team on maintaining deployed policies and managing administrative workflows.
The Problem
Challenges We Solve
The situations that bring organisations to this engagement in the first place.
Findings that never get executed
Detailed penetration testing reports and gap assessments exist, but the controls they recommend are never actually deployed.
Complex controls stall in planning
Application whitelisting, Privileged Access Management, and Entra ID Conditional Access are difficult to roll out safely.
Fear of breaking production
Teams hold back on hardening because they cannot risk disrupting day-to-day business operations.
Scope of Service
Remediation Engineering Scope
Hands-on implementation activities across identity, endpoint, and infrastructure layers.
Identity & Conditional Access Hardening
Configuring phishing-resistant MFA, compliant device checks, risk-based sign-in policies, and disabling legacy protocols.
Application Control & Script Hardening
Authoring and enforcing AppLocker/WDAC rules, restricting PowerShell execution, and disabling macros.
Privileged Access Management (PAM)
Eliminating domain admin proliferation, deploying LAPS (Local Administrator Password Solution), and configuring tiering.
Backup Immutability & Recovery Testing
Configuring immutable cloud storage, write-once-read-many (WORM) policies, and conducting full restore simulations.
Methodology
Engineering Execution Roadmap
A controlled, phased implementation methodology to prevent operational disruption.
Remediation Backlog Triage
We review your audit or VAPT report and prioritize findings by CVSS severity and commercial urgency.
Lab Testing & Pilot Deployment
Configurations (e.g., AppLocker rules, Conditional Access) are tested in a non-production pilot group.
Phased Production Rollout
Controls are deployed across your user base in staged rings with continuous monitoring.
Verification Re-Test & Sign-Off
We re-test all remediated controls and issue an updated Audit Clearance Report.
Deliverables

Hardened Configuration Runbooks
Step-by-step engineering documentation for deployed GPOs, AppLocker rules, and Conditional Access policies.
IT Staff Handover & Training Session
Interactive workshop educating internal sysadmins on maintaining controls and managing exceptions.
