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.

01

Identity & Conditional Access Hardening

Configuring phishing-resistant MFA, compliant device checks, risk-based sign-in policies, and disabling legacy protocols.

02

Application Control & Script Hardening

Authoring and enforcing AppLocker/WDAC rules, restricting PowerShell execution, and disabling macros.

03

Privileged Access Management (PAM)

Eliminating domain admin proliferation, deploying LAPS (Local Administrator Password Solution), and configuring tiering.

04

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.

01

Remediation Backlog Triage

We review your audit or VAPT report and prioritize findings by CVSS severity and commercial urgency.

02

Lab Testing & Pilot Deployment

Configurations (e.g., AppLocker rules, Conditional Access) are tested in a non-production pilot group.

03

Phased Production Rollout

Controls are deployed across your user base in staged rings with continuous monitoring.

04

Verification Re-Test & Sign-Off

We re-test all remediated controls and issue an updated Audit Clearance Report.

Deliverables

What You Receive

The artifacts that land in your hands at the end of the engagement.

01

Remediation Completion & Clearance Report

Formally documented proof confirming all audit and VAPT findings have been resolved.

02

Hardened Configuration Runbooks

Step-by-step engineering documentation for deployed GPOs, AppLocker rules, and Conditional Access policies.

03

IT Staff Handover & Training Session

Interactive workshop educating internal sysadmins on maintaining controls and managing exceptions.
