Managed SOC, SIEM, and XDR with one accountable owner from perimeter to recovery

This page is for teams that need managed security services with clear operational ownership, not another tool stack without response accountability. You can review fit criteria, proof for procurement, managed SOC/SIEM and XDR delivery scope, diligence checklist questions, and a direct path to scope your first 90-day plan.

This is a fit if…

  • You want one accountable MSP across NGFW, XDR, SIEM or SOC, persistence detection, and identity and mail flow hardening, not a different vendor for each layer and response path.
  • You need monthly or quarterly posture reporting your board and auditors can follow: open risks, exceptions, incidents with root cause, and patching reality.
  • You want ransomware recovery aligned to immutable backup and tested restores, not "EDR only" while restore remains untested.
  • You use, or plan to use, stacks we run at scale (for example Fortinet, SentinelOne, CrowdStrike, Huntress, and Adlumin) and want them actively operated.

A one off pen test, a checkbox only compliance pack, or product resale without operational ownership. If you need strategy first, start with strategic managed service. If you only need helpdesk support, use IT support.

Evidence your board and auditors can rely on

Trucell runs managed security inside the same assurance and operating system as our core services. Across 10,000+ managed endpoints, we apply integrated controls, run state in HaloPSA, and public governance you can reference during diligence.

  • Assurance, not ad hoc

    Information security and service management expectations are how we run accounts, not a SOC upsell that ignores governance on About . We obtain independent assurance relating to our network designs, security services, and backup and recovery as part of our governance programme.

  • Essential Eight in production

    We assess and run ACSC Essential Eight style mitigations with the tools we already operate, linked to IT support and change, not a one time audit PDF.

  • Sectors and scrutiny

    We support organisations under real scrutiny, healthcare , government, resources, and more. Security reporting should read like that context.

Where managed security still goes wrong

Tools multiply faster than accountability. Alerts stack up, response ownership goes unclear, and leadership still cannot see whether risk is actually going down. Security should feel controlled, not improvised.

  • Best of breed sprawl with no named owner for incident response , so severity one events wait for someone to pick them up.
  • SIEM without playbooks: logs arrive, tickets open, and the same classes of alert recur because root cause never gets fixed.
  • Perimeter and identity optimised in isolation, attackers walk the gap between firewall rules and conditional access.
  • "Compliant" snapshots that never touch behaviour: policies written once, backups assumed, and restores never rehearsed.
  • Ransomware readiness that stops at EDR marketing: rollback untested, immutable recovery never validated, and no named owner when encryption spreads.

You should not need four vendors to learn whether your endpoints, email, and identity tell the same story when something goes wrong.

What we operate for you

These are operated outcomes, not a tool shopping list. We own day to day execution across NGFW, XDR, SIEM or SOC, persistence detection, and control tuning, then report what changed and what still needs action.

  • Managed next generation firewalls

    Policy lifecycle, segmentation, and hardening on stacks we run at scale, including Fortinet (Gold Partner), plus SonicWall, Check Point, and Palo Alto Networks where your architecture calls for them. We also operate mixed estates that include Ubiquiti and Cisco infrastructure.

  • XDR and endpoint response

    SentinelOne Singularity XDR with Active EDR and ransomware rollback; CrowdStrike Falcon where your estate or sector standardises on Falcon telemetry and response. Deployed, monitored, tuned, and escalated as part of managed security, not a silent agent install.

  • Managed detection beyond commodity antivirus

    Huntress is strong for reseller led and persistence style threats. For broader managed detection, Adlumin provides SOC and SIEM workflows that bring SentinelOne telemetry, Forti logs, and Microsoft 365 signals into one pane of glass with a single escalation path.

  • SIEM and 24x7 SOC patterns

    AI assisted SIEM with Adlumin : security operations centre workflows, correlated alerts, and runbooks that turn signals into action, not log storage alone.

  • Ransomware defence and recovery alignment

    Layered defence: XDR rollback and containment, identity and mail flow hardening, plus backup and recovery with immutability and tested restores. We tabletop ransomware scenarios with your owners so recovery is rehearsed, not first attempted under pressure.

  • Email and collaboration security

    Anti phishing, spoofing, and advanced threat protection layered with Microsoft 365 hygiene: sensible defaults, fewer gaps between mail flow and identity.

  • Identity, device, DNS, and web protection

    MFA, conditional access, and privileged access patterns aligned to Entra ID where you use Microsoft, with Intune device compliance and endpoint policy enforcement; DNS and web filtering (e.g. Cisco Umbrella) to cut off abuse before it reaches the endpoint.

  • Essential Eight (ACSC) roadmaps and run state

    Assess, prioritise, and implement the Australian Cyber Security Centre Essential Eight mitigations with the same tools we already operate, then keep them in run state through IT support and managed security, not a one off audit pack.

  • Cybersecurity education and awareness

    Phishing simulations, role based security awareness, and executive friendly reporting with short modules staff can complete during normal workdays. Paired with vulnerability scanning and remediation cadence; see also Essential Eight (ACSC) and NIST CSF style alignment without checkbox theatre.

Why teams choose Trucell

You get an Australian MSP model built for regulated environments where Trucell is trusted as an operational authority in managed security: accountable operations, evidence ready reporting, and change control that keeps security aligned with real world delivery.

  • Assurance backed operations

    An integrated management system covering information security, privacy, service management, and continuity, so delivery matches what we commit in contract and audit, not ad hoc heroics. This is how we establish authority in managed security: controls are documented, measured, and continuously improved through recurring reviews, not claimed in marketing and forgotten in operations.

  • Integrated with how we run IT

    Service desk and change through HaloPSA; NinjaOne for endpoint operations; infrastructure visibility alongside cloud and network work, fewer handoffs when an incident spans layers. Security, service desk, and infrastructure teams operate in one delivery system so response paths stay clear during live incidents.

RFP checks: what to ask vendors, and what we show

Security procurement gets specific quickly. Use these plain language checks in evaluation meetings to separate operated capability from slideware.

  • SOC, SLAs, and hours

    What to ask: 24x7, follow the sun, or business hours coverage, and what the contract actually says for response times? How we answer: we document coverage and escalation in the proposal and map both to runbooks, not a generic "managed SOC" line item.

  • XDR: who reads the console

    What to ask: is anyone reviewing alerts and tuning policies weekly, or is EDR installed and forgotten? How we answer: managed security includes ownership of response paths with IT support , with reporting that shows what changed, not just ticket volume.

  • SIEM: signal versus storage

    What to ask: are you buying log retention or triaged, correlated use cases and playbooks? How we answer: we scope Adlumin style workflows to your estate and define what gets escalated, suppressed, and fixed at root cause.

  • Ransomware: EDR plus recovery

    What to ask: is immutable backup and a rehearsed restore on the same cadence as EDR rollback? How we answer: we align to backup and recovery and tabletops so recovery is not first tested under duress.

  • Identity, M365, and mail

    What to ask: how will conditional access, phishing, and break glass be operated after go live? How we answer: the same change and incident path as the rest of managed services, with Microsoft 365 and Entra in scope where you use them.

  • References and sector fit

    What to ask: can we speak to a reference in our sector, at similar scale? How we answer: we line up references to industry and size where we can. Public pages do not list every account; the next step is a fit call, then proportionate diligence.

Get a practical gap view in one call

Bring three inputs: your current firewall/XDR/SIEM stack, your recovery approach, and your reporting expectations. We map the highest priority gaps and outline a practical first 90 day plan. You leave with clear next steps, not a product matrix.

Use these three diligence questions before you sign

Vendors sell features. Resilient operations need named owners, measurable outcomes, and rehearsal. Use these in shortlist and clarification rounds.

  • Who owns incident response?

    Named people, escalation paths, and after hours, not "the SOC will email someone." Ask for a joint drill calendar, not a slide.

  • What the monthly report actually proves

    Open risks, exceptions, patching reality, and incidents closed with root cause. Vanity charts without owners are a warning sign.

  • Recovery is part of security

    If backup immutability and restore tests are not on the same operating rhythm as EDR, assume ransomware will find the gap.

Your 4 step managed security operating plan

We align assess, deploy, detect, and improve to your reporting cadence, so posture reviews show progress, exceptions, and patching reality, not vanity metrics.

  1. Assess

    Current controls, coverage gaps, identity boundaries, and what "good" means for your sector, before we swap vendors or add SKUs.

  2. Design & deploy

    Target architecture for firewall , XDR / Falcon , Huntress , and SIEM/SOC ; phased rollout with change windows your business can absorb.

  3. Detect & respond

    SOC workflows, escalation paths, and joint drills with your team, so containment and recovery are rehearsed, not first attempted under pressure.

  4. Review & improve

    Monthly or quarterly posture reporting: open risks, incidents, patching compliance, and agreed exceptions, with strategic reviews when you want roadmaps, not just tickets.

What strong security operations look like

We optimise for fewer unknowns: named owners, tested response, and reporting your board can follow, without drowning operators in noise.

When it is working

  • Alerts route to people who can act, with runbooks that match your environment, not generic playbooks from a catalogue.
  • Posture reporting shows what changed, what is still open, and who owns the exception.
  • Backup and identity assumptions tested on a schedule, not "we will get to it after the project."

When it breaks down

  • Ticket volume celebrated while the same classes of incident repeat.
  • EDR installed but nobody reviews the console, rollback exists only on paper.
  • Audits pass while operators know the brittle parts were never in scope.

Request a managed security fit recommendation

Share your current stack and risk priorities, then continue to contact intake with a prefilled brief.

This routes to our contact form so we can scope coverage and ownership quickly.

No obligation, we will recommend a practical first step.

Turn perimeter, identity, and recovery into one accountable security line

Share your stack and operating context, including whether incident response is internal, external, or shared. We reply with a concrete operating scope, reporting cadence, and next step plan, so you can decide quickly and avoid tool sprawl with no owner. Where your current stack is fit for purpose, we keep and optimise it. No obligation, just a clear recommendation you can act on.

If you are shortlisting providers, run this checklist first to compare ownership, SOC depth, and recovery alignment before booking.

Managed security services FAQ

Common procurement and operational questions before onboarding.

What does managed security services include?

Managed security usually includes firewall operations, XDR monitoring, SIEM and SOC workflows, identity hardening, incident response coordination, and reporting cadence.

How should SIEM and SOC operations be evaluated in procurement?

Procurement should test for triage ownership, escalation SLAs, use case tuning, and root cause remediation outcomes, not only log collection capability.

Why must security and backup be aligned for ransomware resilience?

Security containment without tested immutable recovery can still result in prolonged outages. Both controls must run under one incident and recovery workflow.

How do Essential Eight controls fit into managed security operations?

Essential Eight controls should be implemented as operational controls with ownership, change management, and recurring evidence rather than one off audit documentation.
