Managed SIEM Service South Africa
Most organisations have security data — few have the expertise to turn it into useful intelligence. Beyond Cyber’s Managed SIEM Service gives you complete, correlated visibility across your environment, powered by LevelBlue USM Anywhere and integrated Tenable Nessus vulnerability scanning. We handle the platform, the tuning, and the monitoring. You get clear, actionable insight.
See Everything. Miss Nothing.
Managed SIEM Service Powered by LevelBlue USM Anywhere™ & Tenable Nessus
What Is a SIEM — and Why Does It Matter?
A SIEM aggregates log data from every device, application, and service in your environment — firewalls, endpoints, servers, cloud platforms, identity systems, email — and correlates events to identify patterns that indicate a real security incident.
Without a SIEM, security events are siloed. Your firewall sees one thing. Your endpoint agent sees another. Your identity system sees a third. Attackers exploit exactly that gap — moving slowly, leaving fragments of evidence across different systems that in isolation appear unremarkable. Together, they tell a very different story.
Organisations with a SIEM deployed detect breaches 74 days faster and reduce the average cost of a breach by more than 20% — IBM Cost of a Data Breach Report.
Built on Proven, Enterprise-Grade Technology
LevelBlue USM Anywhere™
A truly cloud-native SaaS security monitoring platform — not a legacy on-premises SIEM retrofitted for the cloud. USM Anywhere unifies threat detection, incident response, and compliance management across on-premises, cloud, and hybrid environments in a single console. Direct API hooks into AWS, Azure, and GCP deliver richer, more accurate security data across your entire estate.
Tenable Nessus
The industry’s most widely deployed vulnerability scanner — named a Customers’ Choice in the 2025 Gartner Peer Insights Voice of the Customer for Vulnerability Assessment. Integrated directly with USM Anywhere, Nessus enriches every SIEM alarm with real-time vulnerability context. When an alert fires on an asset, analysts immediately know what unpatched vulnerabilities exist on that asset — transforming a signal into an actionable priority.
What USM Anywhere Delivers
Asset Discovery
Automatically discovers all IP-addressable assets, maintaining a live inventory without manual effort
Network Intrusion Detection
Monitors traffic in real time for attack signatures, port scans, lateral movement, and C2 communications
SIEM Log Management
Collects, normalises, and correlates log data from every source using a graph-based correlation engine
Endpoint Detection & Response
LevelBlue Agents on Windows, macOS, and Linux provide continuous monitoring of process execution, user activity, and file integrity
Behavioural Monitoring
Detects anomalous access patterns, privilege escalation, and data movement across AWS, Azure, and VMware
Threat Intelligence
Continuously enriched by LevelBlue Labs and the Open Threat Exchange (OTX) — 450,000+ researchers, 20 million+ threat indicators daily
Alarm & Incident Management
Confirmed threats surface as structured alarms with full context, event timeline, and recommended response actions
Log Retention & Forensics
Raw logs retained long-term for forensic investigation, incident reconstruction, and compliance mandates
Compliance Reporting
Pre-built reports for POPIA, PCI-DSS, ISO 27001, GDPR, HIPAA, SOC 2, and NIST CSF
Vulnerability Intelligence Built Into Every Alarm
Most organisations run their SIEM and vulnerability scanner as two entirely separate programmes. Our integrated approach eliminates that disconnect — when the SIEM raises an alarm, the vulnerability context for the affected asset is immediately available.
Vulnerability Discovery
450+ pre-configured Nessus scan templates across operating systems, network devices, web applications, databases, and cloud infrastructure. Scan findings flow into USM Anywhere as structured asset intelligence, providing context for every alarm.
Risk Scoring & Prioritisation
Every finding scored using both CVSS (severity) and EPSS (Exploit Prediction Scoring System — actual exploitation likelihood). SIEM alarms enriched with these scores so analysts instantly know which alerted assets carry high-severity unpatched vulnerabilities.
Compliance Scanning
Built-in compliance checks aligned to CIS Benchmarks, PCI-DSS, ISO 27001, GDPR, POPIA, and NIST. Pass/fail results per control feed directly into USM Anywhere compliance reports.
Live Results
Nessus Live Results automatically re-evaluates historical scan data against every new plugin update — ensuring vulnerability context remains current even between scheduled scan cycles.
Incident Response Enrichment
When USM Anywhere raises an alarm, the Tenable integration surfaces any known vulnerabilities on the affected asset immediately — allowing analysts to determine whether the activity could represent active exploitation of a known weakness.
Integrates With Your Existing Technology Stack
USM Anywhere includes hundreds of BlueApps — purpose-built integrations that extend threat detection and enable automated response actions across the tools already in your environment.

Compliance Reporting Built In
POPIA makes continuous monitoring a compliance obligation for most South African organisations. USM Anywhere treats compliance as a first-class capability — not an afterthought. Audit preparation that previously required days of manual work can be completed in hours.
POPIA
South Africa’s Protection of Personal Information Act requires appropriate technical measures to protect personal information and detect breaches within defined timeframes. USM Anywhere’s continuous monitoring, breach detection, and detailed audit log retention directly support these obligations — with a pre-built POPIA compliance report ready to use for regulatory review.
PCI-DSS
Mandatory for organisations handling card payment data. USM Anywhere covers network monitoring, log review, change detection, access control, and cardholder data environment segmentation requirements.
ISO 27001
Continuous monitoring, risk management evidence, incident management, and access control logging aligned to the ISO 27001 information security management standard.
GDPR
Applicable to any organisation handling EU personal data. USM Anywhere supports incident detection and notification timelines, access logging, and data processing oversight requirements.
NIST CSF
USM Anywhere’s workflow maps natively to the NIST Cybersecurity Framework’s five functions: Identify, Protect, Detect, Respond, and Recover.

Frequently Asked Questions
Q: What makes LevelBlue USM Anywhere different from other SIEM platforms? USM
Anywhere is a genuinely cloud-native platform — built for the cloud era rather than retrofitted from a legacy on-premises architecture. It unifies threat detection, vulnerability management, and compliance reporting in a single console, and is continuously updated by LevelBlue Labs with new detection content. For organisations without a dedicated security engineering team, this removes the burden of building and maintaining detection logic from scratch.
Q: Do we need to replace our existing security tools to use this service?
No. USM Anywhere integrates with most major security tools via BlueApps — including Palo Alto Networks, SentinelOne, CrowdStrike, Microsoft 365, Okta, and Cloudflare. We assess your existing stack during onboarding and configure integrations to maximise the value of what you already have.
Q: How is the Tenable Nessus integration different from running a standalone vulnerability scanner?
A standalone scanner tells you what vulnerabilities exist. Our integrated approach enriches every SIEM alarm with the vulnerability status of the affected asset in real time — so when a threat is detected, analysts immediately know whether the alerted system has unpatched vulnerabilities that match known exploitation techniques. That context is the difference between a low-priority alert and an immediate incident.
Q: How does this relate to your SOCaaS offering?
The Managed SIEM Service and SOCaaS are fully integrated — they operate from a shared platform. Clients who want both SIEM management and 24/7 analyst coverage across endpoint detection can combine the two services without any handoff gaps between providers.
Q: What compliance frameworks do your reports cover?
Reports are pre-built for POPIA, PCI-DSS, ISO 27001, GDPR, HIPAA, SOC 2, and NIST CSF. Custom report formats are available on request.
Q: Where is our data hosted — and does it stay in South Africa?
USM Anywhere is hosted on AWS across 12+ global regions. South African clients are typically served from the nearest appropriate region, with data residency options available to meet POPIA and other compliance requirements. We confirm hosting configuration during scoping.
