What's included

Every engagement covers these as standard.

Microsoft Defender or SentinelOne EDR, MDR, Sentinel SIEM, identity-threat detection, awareness training, backup and a tested disaster-recovery position. Maps to ASD Essential Eight, ACSC guidance and ISO 27001 controls.

  • Endpoint security essentials, next-generation antivirus, anti-ransomware, host firewall, and secure configuration baseline across every workstation and server in the environment.
  • EDR / XDR / MDR, Microsoft Defender for Endpoint or SentinelOne, monitored 24×7. Threats are contained automatically; the SDS analyst team reviews every alert and tells you what we did, in plain English.
  • Identity protection, Entra ID conditional access, MFA enforcement, dark-web credential monitoring, anomalous-sign-in detection, and quarterly access reviews so leavers never linger in the directory.
  • Awareness training & phishing simulation, quarterly micro-modules in the language your staff use, simulated phishing campaigns, and a leaderboard for the C-suite (because executives are the targets).
  • Backup & recovery, daily image backups to immutable storage, monthly tested restores, RPO ≤ 1 hour for critical systems, retention aligned to your record-keeping obligations.
  • Disaster recovery position, a written DR plan with named owners, recovery objectives, system dependencies, and a quarterly tabletop exercise so you find out what breaks before the audit does.
  • SIEM coverage, Microsoft Sentinel or equivalent, ingesting workstation, server, identity, M365 and key SaaS logs. Twelve months of searchable telemetry. One pane of glass.
  • Compliance reporting, quarterly posture reports mapped to ASD Essential Eight, the Australian Cyber Security Centre guidance, and ISO 27001 controls; suitable for cyber-insurance renewals and board papers.

Quick answers

Things people ask before signing.

The most common questions on this service. If yours isn't here, send it through — we reply within one business day.

Do we get the same kit a tier-1 enterprise gets, or a watered-down SMB version?
The same kit. Microsoft Defender for Endpoint, Sentinel SIEM, and Entra ID Premium are the same products a CBA or a Telstra runs, we operate them at SMB scale and tune them for an SMB threat model. The licence cost lands in your monthly seat fee; the operational cost is what you pay us to run them.
Will you help us reach ASD Essential Eight maturity level 1?
Yes. The default coverage above lands you at Maturity Level 1 across all eight controls within the first 90 days for most environments, the gaps are usually application control, macro hardening, and patching cadence. We document where you are, where you should be, and what it costs to close each gap. Maturity Level 2 is a separate scoping exercise.
What happens when there’s an actual incident?
We contain first, then call. Confirmed malicious activity triggers automated containment (host isolation, account disable, suspicious mail purge) inside minutes; a senior engineer rings the nominated incident contact at the same time. You get a written timeline, root-cause analysis, and a remediation plan within five business days, and we hand-hold the cyber-insurance notification if it triggers.
Do you do penetration testing?
Not in-house, we partner with CREST-accredited testers and coordinate the engagement, scope, and remediation on your behalf. Annual external pen-test plus internal-network test is the SDS recommendation for any business with sensitive client data, and the cost runs $8,000–$25,000 depending on scope. We project-manage; you don’t.
How does cyber insurance fit in?
Most modern cyber-insurance applications now ask 60–120 specific control questions, MFA coverage, EDR vendor, backup immutability, awareness-training cadence, incident response plan. The default SDS coverage answers "yes" to roughly 80% of those by design; we walk you through the rest before renewal so the premium reflects your actual posture, not a guess.
Is data sovereignty a problem if you use Microsoft tools?
No. Defender, Sentinel, and Entra all run in Australia East (Sydney) and Australia Southeast (Melbourne) regions by default, your telemetry stays onshore. We document the data-flow on day one and pin region-specific configurations in policy so a future Microsoft change can’t silently shift it.
Get an honest read on your cyber posture.

Send a short brief, staff count, current security tooling, and any specific worries (insurance renewal, recent near-miss, board ask, supplier requirement), and we come back inside one business day with a written gap analysis against the ASD Essential Eight and a costed plan to close the priority gaps.

No spend on a first conversation. Senior engineer, not salesperson.
