Cybersecurity

System Hardening

Discuss your project with our technical team

Service scope and delivery

We review and apply secure configuration baselines across Windows Server, Active Directory, endpoints, Microsoft Entra ID, Microsoft 365, firewalls, and backup platforms. We use relevant CIS Benchmarks, NIST guidance, and vendor recommendations to reduce unnecessary services, privileges, legacy access, and administrative exposure. Changes are piloted against application dependencies, with documented exceptions and rollback procedures where appropriate. Your team receives baseline records, validation results, and maintenance actions to keep the controls effective after deployment.

System Hardening: every engagement starts with agreed systems, responsibilities, an implementation plan, validation criteria, and handover documentation.

Microsoft Entra ID Hardening

We review MFA coverage, Conditional Access, privileged roles, guest access, application consent, service principals, and identity lifecycle controls. We introduce least-privilege role assignments and, where licensed, PIM and risk-based policies. Report-only analysis and pilot enforcement help test access before broader rollout. Emergency-access accounts, sign-in logging, and exception ownership are included in the review. Policy records and validation results give your team a maintainable identity-security baseline.

Microsoft 365 Hardening

We review and harden Microsoft 365 messaging and collaboration controls around licensed capabilities and business workflows. The service covers phishing protection, SPF, DKIM and DMARC, mailbox forwarding, external sharing, application consent, audit logging, and relevant Microsoft Secure Score recommendations. We review configuration across Exchange Online, SharePoint, OneDrive, and Teams and test changes before enforcement. Documented settings, exceptions, and review tasks help your team maintain protection as users and applications change.

Windows Server and Active Directory Hardening

We apply appropriate Windows Server and Active Directory security baselines using relevant CIS Benchmarks, NIST guidance, and vendor recommendations. The service covers Group Policy, privileged groups, service accounts, authentication settings, audit policies, patching, and unnecessary services. We review domain and application dependencies, pilot changes, and document rollback and exceptions. Configuration evidence and test results help your team maintain hardening without losing sight of compatibility requirements.

Windows Endpoint and Intune Hardening

We configure endpoint security through Intune, Group Policy, or another agreed management approach. The work covers security baselines, BitLocker, Microsoft Defender controls, host firewall policies, update rings, local administrator restrictions, and device-compliance settings where supported. We pilot policies, check application behavior, and review deployment coverage and failures. Your team receives a record of policies, protected devices, exceptions, and ongoing review tasks.

Firewall and Network Device Hardening

We review and secure the administration and configuration of firewalls, switches, wireless systems, and other agreed network devices. We review firmware, management-plane exposure, administrator authentication, unused services, logging, and configuration backups. The service covers management-network restrictions, secure administration protocols, rulebase cleanup, and least-privilege network flows. Connectivity and failover tests validate the approved design, while documented configurations and exceptions support ongoing change control.

Backup and Recovery Platform Hardening

We review the controls that protect backup infrastructure from misuse, deletion, and compromise. The work covers MFA, separate administrator credentials, least-privilege access, repository isolation, protected retention, offsite copies, and immutable storage where supported. We improve failure and configuration-change alerting and validate restoration through agreed tests. Your team receives configuration records, recovery runbooks, and documented gaps against the agreed RPO and RTO.
