TIERS Cyber Defense
System & Network Hardening
Strengthen critical systems, identity controls, networks, remote access, and administrative configurations using risk-based and defensible security baselines.
Reduce unnecessary attack surface
Turn assessment findings into stronger configurations
Hardening engagements focus on practical configuration improvements that make systems more resistant to credential theft, privilege abuse, lateral movement, unauthorized remote access, and common attack techniques.
Endpoint & Server Hardening
Windows, Windows Server, Linux, macOS, local security policy, administrative controls, patching, logging, and endpoint protection.
Network Hardening
Firewalls, routers, switches, segmentation, virtual local area networks (VLANs), wireless networks, virtual private networks (VPNs), management interfaces, and remote access pathways.
Active Directory & Entra ID
Privileged access, identity controls, attack paths, legacy protocols, policy configuration, and administrative separation.
Email & Authentication
Multifactor authentication (MFA), Conditional Access, Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), Domain-based Message Authentication, Reporting, and Conformance (DMARC), risky sign-in controls, and account-takeover defenses.
Logging & Visibility
Improve the audit and security telemetry needed to detect suspicious activity and support later investigation.
Baseline Validation
Use recognized configuration guidance such as CIS Benchmarks where appropriate, adjusted for operational requirements.
Operationally realistic
Hardening should not break the business
Security baselines are starting points, not blind checklists. TIERS Group can identify dependencies, stage changes, document exceptions, and validate controls so security improvements remain compatible with business operations.
