Active Directory Hardening Services
Your Active Directory is the keys to your kingdom — and attackers know it. Lock down misconfigurations, privilege sprawl, and legacy vulnerabilities before they become your next incident.
What is Active Directory Hardening?
Active Directory (AD) hardening is the process of strengthening your AD environment by eliminating security gaps, reducing excessive privileges, and aligning configurations with modern security best practices. It’s a proactive approach that helps enterprises reduce identity-based attack surfaces and prevent threat actors from exploiting common weaknesses in AD.
Reduced Attack Surface
Eliminating stale accounts, legacy protocols, and misconfigured permissions removes the footholds attackers depend on.
Stronger Privilege Controls
Enforcing least privilege and tiered administration limits how far any compromised account can reach.
Ransomware Resilience
Hardened environments contain lateral movement, reducing blast radius and accelerating recovery.
Compliance Alignment
Secure configurations, consistent logging, and enforced access controls satisfy audit requirements across HIPAA, PCI-DSS, and SOX.
Why Active Directory Hardening Matters
Organizations that delay hybrid identity modernization face mounting risks. The longer these issues persist, the harder they become to remediate and the more attractive your environment becomes to attackers.
Credential-Based Attacks
Misconfigured permissions, stale accounts, and legacy protocols like NTLM give attackers exactly what they need to move fast and go deep.
Undetected Privilege Escalation
Without hardened privilege boundaries, threat actors can exploit accumulated permissions to reach domain controllers and critical infrastructure.
Ransomware Spread
An unhardened AD environment gives attackers the lateral movement paths they need to maximize damage before you can respond.
Compliance Gaps Become Audit Failures
Without enforced access controls and consistent logging across your AD environment, demonstrating regulatory compliance requires painful manual effort.
Don't wait for an incident to force action.
Get a Free Security AssessmentSecurity & Operational Challenges We Address
Ravenswood's hybrid identity services address the security and operational challenges that undermine access management in complex environments.
Excessive Privileges and Standing Admin Rights
Many organizations struggle with overly broad admin rights and accounts with unnecessary standing access. These represent high-value targets for attackers.
Our Solution: We eliminate excessive permissions and implement just-in-time access to ensure elevated rights are granted only when needed.
Misconfigurations and Insecure Defaults
Outdated settings, legacy configurations, and insecure defaults leave AD environments vulnerable.
Our Solution: We identify and correct these to align with Microsoft-recommended baselines.
Legacy Protocols and Weak Authentication Controls
NTLM, LDAP without TLS, and other legacy protocols create easy paths for credential theft.
Our Solution: We help organizations phase out risky protocols and adopt secure authentication methods like Kerberos and smartcard enforcement.
Lateral Movement Paths and Tiering Failures
Flat or loosely structured AD environments often allow attackers to move freely once inside.
Our Solution: We redesign administrative tiering to contain movement and protect critical assets.
Limited Visibility into Identity Risk
Without clear insight into privilege assignments and attack paths, it’s difficult to assess your true risk.
Our Solution: We provide visibility through posture assessments and Microsoft tools like Defender for Identity.
Stale Accounts and Orphaned Access
Dormant user accounts, unused service accounts, and unrevoked access from departed employees create exploitable entry points that often go unnoticed.
Our Solution: We audit and remediate orphaned identities to eliminate hidden vulnerabilities across your environment.
Assessment-led Methodology
Ravenswood follows an assessment-led methodology that ensures every AD hardening engagement is tailored to your organization's unique environment, risk tolerance, and security requirements.
AD Posture Assessment and Risk Analysis
We start by evaluating your current AD environment, identifying risky configurations, excessive privileges, and common exploitation paths using tools like Microsoft Defender for Identity and BloodHound.
Privilege and Attack Path Mapping
We map out admin rights, nested group memberships, and attack paths that adversaries could exploit, enabling targeted remediation.
Group Policy and Configuration Hardening
We align GPOs with Microsoft’s security baselines and remove insecure or outdated settings. This includes enforcing LAPS, restricting RDP, and securing logon policies.
Tiered Administrative Model Implementation
Using Microsoft’s tiered administration model, we separate control of high-value assets from everyday operations, limiting access to sensitive systems.
Identity Governance and Access Control Improvements
We streamline privileged access using principles of just-in-time (JIT) and just-enough-access (JEA), often integrating with Microsoft Entra Privileged Identity Management (PIM).
Validation, Documentation, and Remediation Roadmap
After remediation, we deliver documentation outlining changes made and a roadmap for maintaining AD security over time.
Measurable Improvements Across Your Identity Attack Surface
Partnering with Ravenswood for AD hardening delivers a stronger, more defensible environment — with outcomes you can measure and demonstrate to leadership and auditors.
Fewer
Attack VectorsReduced Identity Attack Surface
By removing unused accounts, outdated protocols, and excessive privileges, you drastically shrink the number of exploitable vectors in your AD.
Tighter
Access ControlsStronger Privilege Boundaries and Admin Controls
We help implement tiered administration, RBAC, and JIT access to enforce the principle of least privilege across your environment.

AD Hardening Experts You Can Trust
Active Directory is the most commonly attacked component of enterprise IT — and once compromised, it gives attackers the keys to your entire environment. Hardening it takes more than a checklist; it takes a real understanding of how attacks actually unfold.
Ravenswood specializes in Active Directory security, with hands-on expertise remediating environments after security incidents and closing the attack paths that lead to full domain compromise. Our team includes Microsoft Most Valuable Professionals (MVPs) and Certified Masters who have secured Active Directory environments for international brands, government agencies, and regulated industries.
Just as importantly, we work as a strategic partner to your security and infrastructure teams, not just as a technical implementer. We build hardening programs that close privilege escalation paths, tighten Group Policy and delegation, and reduce your attack surface — without disrupting business operations.

Frequently Asked Questions
What does an Active Directory hardening engagement include?
It includes an in-depth assessment, privilege and attack path analysis, Group Policy hardening, protocol remediation, and a roadmap for ongoing improvements.
How is this different from an AD health check?
A health check evaluates overall AD performance and reliability. Hardening focuses specifically on security, risk reduction, and identity attack surface elimination.
How long does hardening take?
Most engagements take between 3–6 weeks, depending on the complexity of your environment.
Will hardening impact users or production systems?
We take a cautious, staged approach and validate every change to avoid disrupting user experience or business operations.
Can you harden hybrid AD and Entra ID environments?
Yes. We specialize in hybrid identity and can secure both on-premises AD and cloud-based Entra ID configurations.
How often should Active Directory be hardened?
Hardening should be revisited annually—or sooner after major organizational changes like mergers, cloud migrations, or cyber incidents.
