FAQs

Find answers to commonly asked questions about our cybersecurity solutions and services.

What exactly does CyberQuell do?

CyberQuell is a managed cybersecurity provider. We monitor your environment 24/7, detect threats before they cause damage, and respond on your behalf, so you don't need to build or staff a security operations centre internally. We specialise in Microsoft-native security tools: Sentinel, Defender XDR, Intune, and Defender for Office 365.

Who do you work with?

Primarily mid-market enterprises (50–5,000 employees) that rely on Microsoft 365 and want enterprise-grade security without the cost of a full in-house SOC. We also work with MSPs who want to offer white-label SOC services to their own clients.

Is a managed SOC cheaper than hiring in-house security staff?

In-house analysts cover business hours, need months to hire, and cost $120k–$180k per head before benefits, tooling, and training. CyberQuell gives you a team of certified security engineers available around the clock, already tooled up and operational within days. For most mid-market companies, a managed SOC costs less than one senior analyst FTE while delivering broader coverage.

What does 24/7 SOC monitoring actually mean in practice?

Our analysts watch your environment continuously, every alert, every anomaly, every spike in activity. When something looks suspicious, we triage it immediately. If it's a confirmed threat, we contain it and notify you with full context, not just a ticket. You're never left managing alerts yourself.

What happens when a threat is detected?

We follow a defined playbook: isolate the affected asset, investigate the blast radius, contain lateral movement, and remediate. You get a real-time notification and a post-incident report. For lower-severity events we handle them silently and log them in your monthly report.

Can threat detection stop an attack before damage occurs?

Often, yes. Most breaches involve a dwell time, the window between initial access and actual damage, that averages weeks or months. Our continuous monitoring and threat hunting is designed to catch adversaries during that window, before exfiltration or ransomware deployment.

What email threats do you protect against?

Business email compromise (BEC), spear phishing, impersonation attacks, malicious attachments, zero-day links, and bulk spam. We layer Microsoft Defender for Office 365 with policy hardening, safe links/attachments enforcement, anti-spoofing rules, and ongoing tuning — so phishing sensitivity is dialled in without flooding inboxes with false positives.

Do you help with GoDaddy Microsoft 365 defederation?

Yes. If your Microsoft 365 tenant was provisioned through GoDaddy, you're operating under GoDaddy's federated environment, which limits your admin control, security configuration, and licensing flexibility. We handle the full defederation process, migrating your tenant to a standalone Microsoft account with no email downtime.

What is Managed XDR and how is it different from traditional antivirus?

Traditional antivirus catches known malware signatures. Extended Detection and Response (XDR) correlates signals across endpoints, email, identity, and cloud workloads to catch sophisticated attacks that don't trigger signature-based tools, like living-off-the-land attacks, credential abuse, or lateral movement. Our Managed XDR service layers Microsoft Defender XDR with 24/7 analyst oversight, so detections actually get acted on.

Which security tools do you use?

We work with the stack you already run. For SIEM: Microsoft Sentinel or Splunk, and we can operate most other platforms your logs already flow into. For endpoint and XDR: Microsoft Defender XDR or CrowdStrike Falcon. For device management: Microsoft Intune. We also work in Palo Alto Networks, Google Cloud, and Oracle Cloud Infrastructure environments. Our deepest certifications are in the Microsoft stack, and we never force a rip-and-replace: we map what you have during discovery and fill the gaps

Do you support non-Microsoft tools like CrowdStrike or Splunk?" with this answer

Yes. CyberQuell is stack-flexible. If your endpoints run CrowdStrike Falcon, our analysts monitor and respond through Falcon. If your SIEM is Splunk, we run detection engineering, alert triage, and investigations in Splunk. Many clients run a mix, for example CrowdStrike for EDR with Microsoft 365 for email and identity, and we correlate across all of it. You choose the tools; we run the security operations

Do you offer white-label SOC services for MSPs?

Yes. MSPs can resell CyberQuell's SOC monitoring, SIEM, and MDR capabilities under their own brand. We operate as your back-end security team, and you own the client relationship. Speak to us about partner programme structure and margins.

How long does onboarding take?

Most clients are fully onboarded within 2–4 weeks. That includes connecting your data sources to Microsoft Sentinel, configuring detection rules, baselining your environment, and briefing your team on escalation workflows. Complex multi-site or hybrid environments may take slightly longer.

Do I need an in-house IT team to work with CyberQuell?

No. We work with companies that have no dedicated security staff. We integrate directly into your workflows, whether that's Slack, Teams, or email, and handle security operations end-to-end. If you do have internal IT, we act as an extension of that team.

Can I keep my existing security tools?

Usually yes. We integrate with most common endpoint, identity, and network tools. During discovery we'll map what you have, identify what's redundant, and recommend whether to consolidate or extend.

Can CyberQuell help with compliance requirements like HIPAA, PCI-DSS, SOC 2, or ISO 27001?

Yes. Our SIEM (Microsoft Sentinel) is configured to generate the log retention, audit trails, and reporting needed for major frameworks. We also conduct security assessments aligned to compliance requirements and can work alongside your auditor to close gaps. We don't act as a QSA or certification body, but we prepare your environment and documentation.

Which SIEM do you use for compliance reporting, and why?

Microsoft Sentinel. It ingests logs from across your Microsoft and third-party stack, retains them at scale, and maps alerts to MITRE ATT&CK, which auditors and compliance teams can directly reference. It also avoids the cost and complexity of legacy on-premise SIEM deployments.
