Security Engineering
Security findings that get fixed, not filed.
Most security teams can find the problem and cannot change the infrastructure underneath it. North Ark detects it, designs the fix, implements it and verifies it, because the same engineers work across identity, endpoint, network and cloud.
- Microsoft Partner
- AZ-104 and AZ-305 certified engineers
- Senior engineers only
- Brisbane-based, working across Australia
Identity and access
- Entra ID tenant design, hybrid identity health and Conditional Access policy sets that are tested before enforcement
- MFA rollout, legacy authentication removal and authentication strength for privileged roles
- Privileged access: PIM, break-glass accounts, admin separation, service principal and app registration hygiene
- Microsoft 365 tenant configuration and licence alignment against the controls you use
Endpoint and workload
- Intune compliance and configuration baselines, Defender for Endpoint onboarding and tuning
- Defender for Cloud posture across Azure subscriptions, with findings routed to owners
- Vulnerability and patch remediation with evidence of closure
Detection and response
- Microsoft Sentinel workspace design, data connectors, analytics rules and cost control on ingestion
- Response playbooks and automation for the incidents that recur
- Log architecture that keeps the evidence you will need in an investigation
Network and architecture
Segmentation, firewall rule rationalisation, private connectivity for platform services, and zero trust decisions sequenced against what the environment can absorb. Controls are chosen for this estate, not lifted from a generic checklist.
Round-the-clock monitoring
Attacks often start outside business hours. When an environment needs round-the-clock cover, North Ark's security operations centre watches alerts overnight, on weekends and on public holidays.
The SOC works from detections North Ark engineers for your environment, so alerts are worth acting on. We agree with you which containment actions it may take on its own, such as isolating a device or disabling an account, and every overnight incident is fixed at the cause and appears in your monthly engineering report.
Essential Eight
Findings are mapped to the ACSC Essential Eight where it applies. When you need a measured maturity level and a plan to reach your target, the Essential Eight assessment tests each strategy against evidence and the uplift is delivered as code.
How it fits
Security engineering is delivered as Transformation Engineering when there is a defined uplift, and as part of Managed Engineering when North Ark owns the controls continuously. An Infrastructure Review or an Essential Eight assessment is the usual way to establish what to fix first.
Questions buyers ask
Do you provide 24/7 security monitoring?
Yes. Our security operations centre monitors around the clock, including overnight, weekends and public holidays, and North Ark engineers fix what it finds.
Can you work with our existing SOC or MDR provider?
Yes. We tune the detections they work from, agree the handoff for incidents, and fix the causes they identify.
Do you work with Microsoft Sentinel only?
Most of our detection work is on Microsoft Sentinel and Defender XDR, because that is where most Microsoft-centred estates already are. We work with the tools you have.
Can you get us to Essential Eight Maturity Level Two?
We start by measuring where you are against evidence, then agree a realistic target and plan with you. The uplift is delivered in planned phases, every setting is recorded, and we reassess when it is done.
Do you do penetration testing?
Yes. We run external, internal, web application and Microsoft 365 and Azure penetration tests, fix the findings and retest.
How do you keep Sentinel costs under control?
By choosing data sources by use, filtering at ingestion, using lower-cost log tiers for investigation data and reviewing ingestion monthly.
