Managed Detection & Response

24/7 managed detection, investigation and response delivered in partnership with CyberOne — one of Africa's leading MSSPs. Every engagement is anchored to NS-CMMF, so detection events feed directly into the client's cybersecurity maturity programme rather than sitting in isolation.

Detection that feeds maturity

Standard MSSP tooling detects threats and generates alerts. What it doesn't do is connect those alerts to the client's underlying security maturity — which gaps in policy, process or technology made the incident possible, and what needs to change to prevent recurrence. Without that connection, detection and maturity improvement remain parallel programmes that never inform each other.

Nucleus Systems partners with CyberOne to deliver MDR services that break that separation. Every engagement is anchored to NS-CMMF, so when a threat is detected and investigated, the findings are contextualised against the client's actual maturity posture across the eight domains. A detected credential attack maps to D3 Identity & Access Management maturity gaps. A ransomware event maps to D5 Resilience & Recovery readiness. Detection events become evidence in the maturity programme, not isolated tickets.

This integration produces a continuous feedback loop: the maturity assessment identifies where detection coverage is weakest; the MDR service monitors those areas most closely; incidents and near-misses update the maturity picture and reprioritise the remediation roadmap. Security operations and security improvement become one programme.

The Partnership

CyberOne MSSP · Nucleus Systems frameworks

CyberOne brings deep SOC operations, SIEM/SOAR infrastructure, EDR/XDR tooling and 24/7 analyst coverage. Nucleus Systems brings NS-CMMF framework integration, maturity context, and the programme management layer that connects detection events to security improvement.

The Differentiator

Incidents become maturity evidence, not just closed tickets

Every investigated incident generates findings that are mapped back to NS-CMMF control gaps. Over time the incident record builds a maturity evidence base that supplements formal assessment cycles — giving boards a continuously updated picture of security posture, not a once-a-year snapshot.

The Alignment

MITRE ATT&CK mapped across all detection content

Detection rules, alert triage and threat hunting playbooks are mapped to MITRE ATT&CK tactics and techniques. Threat reporting gives clients visibility into which adversary techniques are being actively used against their environment — not just which alerts fired.

What's Included

Full-spectrum managed detection and response — from 24/7 SOC coverage and threat hunting through to NS-CMMF maturity integration and board reporting.

24/7 Managed SOC

Round-the-clock security operations centre coverage. Trained analysts monitor, triage and escalate alerts across your environment — no after-hours blind spots, no analyst fatigue gaps.

Threat Detection & Correlation

SIEM/SOAR-driven detection with cross-source correlation. Alerts are enriched with threat intelligence and MITRE ATT&CK context before reaching the analyst queue — reducing noise and improving response quality.

Endpoint Detection & Response

EDR/XDR deployment and management across endpoints, servers and cloud workloads. Behavioural detection, lateral movement identification and automated containment of confirmed threats.

Threat Hunting

Proactive, hypothesis-driven hunting for threats that evade automated detection. Hunting cadence aligned to the client's threat model — sector-specific adversary TTPs, supply chain risk areas and NS-CMMF gaps most likely to be exploited.

Incident Management & Response

Structured incident response from initial triage through containment, eradication and recovery. Post-incident reviews produce findings mapped to NS-CMMF control gaps — closing the loop between detection and maturity improvement.

Vulnerability Management

Continuous vulnerability scanning, risk-based prioritisation and remediation tracking. Vulnerabilities are prioritised by exploitability, asset criticality and NS-CMMF domain risk weighting — not just CVSS score.

Threat Intelligence Integration

Curated threat intelligence feeds mapped to the client's sector and geography. Intelligence is operationalised into detection rules, hunting hypotheses and client-facing threat briefings — not raw feeds sitting unused in a portal.

Monthly Threat & Posture Reporting

Monthly reporting covering threats detected, incidents investigated, vulnerabilities remediated, and NS-CMMF maturity impact. Board-ready format with trend indicators — designed to go directly into governance and risk reporting cycles.

NS-CMMF Integration

The integration between MDR operations and NS-CMMF maturity is what separates this service from standard MSSP delivery — every detection event informs the maturity programme.

Detection Coverage Mapping	Detection coverage gaps are mapped to NS-CMMF domains at onboarding. D4 Threat Intelligence coverage, D6 SOC & Monitoring maturity, and D7 Incident Response readiness all feed directly into the MDR service configuration — ensuring the SOC is watching the areas the maturity assessment identified as weakest.
Incident-to-Maturity Feedback	Every investigated incident generates a post-incident finding mapped to one or more NS-CMMF control gaps. These findings accumulate as evidence between formal assessment cycles — so the next NS-CMMF assessment starts with a richer, more current picture of control effectiveness than a standalone interview-based assessment would produce.
Maturity-Informed Prioritisation	Vulnerability remediation, threat hunting priorities and detection rule tuning are all informed by the client's NS-CMMF maturity profile. Low-maturity domains get higher-intensity coverage — the MDR service concentrates where the organisation is most exposed, not where the tooling is easiest to deploy.
Board Reporting Integration	Monthly MDR reports are formatted to feed directly into board and audit committee reporting cycles. Threat and incident data is presented alongside NS-CMMF maturity trend data — giving boards a unified view of security posture, not separate operational and governance reports that tell different stories.
