Defense · Hardening · Baselines
Hardening & defense.
Reduce attack surface and improve detection.
Most breaches succeed because systems are exposed by default: weak MFA posture, excessive privileges, flat networks, noisy/absent logs, unmanaged endpoints. We implement pragmatic hardening measures aligned with your constraints and your IT reality.
What we harden first
Identity & MFA
Close the easiest entry points (mailboxes, admin accounts).
Privileged access
Reduce admin sprawl and enforce least privilege.
Endpoints
Baseline, updates, EDR posture and secure configs.
Network exposure
Segmentation, remote access, and service reduction.
Backups
Ransomware-resilient backup strategy and tests.
Logs you can use
A foundation for detection and investigations.

Next step
If you need prioritisation first, start with an audit. If you already know the gaps, we can go directly to hardening.
If you are currently under attack (ransomware, account compromise, fraud), use the emergency path.
Emergency response →How we deliver.
A predictable, structured approach: scope, baseline, remediation plan, and controlled changes.
1) Scope
Critical assets, users, remote access and providers.
2) Baseline
Configuration review and quick wins.
3) Remediate
Hardening measures and validation.
4) Sustain
Documentation, handover, and operational cadence.
