NIS2 Compliance Automation: Which of the 10 Article 21 Requirements Can AI Agents Monitor Continuously

The NIS2 directive is now German law. The NIS2UmsuCG (NIS-2-Umsetzungs- und Cybersicherheitsstärkungsgesetz) passed in 2025, and enforcement begins October 2026. That’s not a distant deadline — it’s eight months away.

Most German “Important Entities” (wichtige Einrichtungen) sit at 60–75% readiness according to recent industry surveys. The gap isn’t knowledge. Every CISO knows what Article 21 demands. The gap is capacity.

The typical mid-market compliance team: 1–2 people. The frameworks they manage simultaneously: NIS2, GDPR, ISO 27001, and often TISAX or KRITIS on top. That’s four-plus regulatory frameworks for a team that can barely keep up with one.

AI agents don’t replace compliance officers. They replace the quarterly snapshot with continuous monitoring. The difference: instead of discovering a control failure during a scheduled review three months later, your GRC agent flags it within hours.

Here’s the complete mapping.

The Complete Article 21(2) Mapping

Article 21(2) of Directive (EU) 2022/2555 lists ten categories of cybersecurity risk-management measures. Each one maps differently to AI agent capabilities.

(a) Risk Analysis and Information System Security Policies

What NIS2 requires: Entities must establish policies for risk analysis and information system security, including a systematic approach to identifying, analyzing, and evaluating cyber risks across all critical systems.

What an AI agent does:

• Maintains a living risk register that updates automatically when new CVEs are published, incidents occur, or asset inventories change
• Auto-calculates risk scores using configurable frameworks (likelihood × impact, FAIR methodology, or custom matrices)
• Generates weekly risk trend reports showing score trajectories, not just snapshots
• Flags risks approaching defined thresholds before they breach tolerance levels
• Cross-references risks against BSI IT-Grundschutz Bausteine and ISO 27001 controls to identify coverage gaps

Automation Level: 🟢 CONTINUOUS MONITORING

ISO 27001:2022 Mapping: A.5.1 (Policies for information security), A.6.1 (Screening), A.8.2 (Information classification)

BSI IT-Grundschutz: ISMS.1 (Sicherheitsmanagement), ORP.1 (Organisation)

Agent Type: GRC Agent

What stays human: Risk appetite decisions, policy approval, board-level risk acceptance.

---

(b) Incident Handling

What NIS2 requires: Measures for incident prevention, detection, analysis, containment, response, and recovery. Under the NIS2UmsuCG, significant incidents must be reported to the BSI — early warning within 24 hours, full notification within 72 hours, final report within one month.

What an AI agent does:

• Triages SIEM alerts in real-time, reducing alert noise by correlating events across sources
• Enriches alerts with threat intelligence (MITRE ATT&CK mapping, IoC lookups, CVE context)
• Drafts incident reports in BSI-compliant format, pre-filling known fields
• Tracks the 24h / 72h / 1-month reporting cascade with countdown timers and escalation alerts
• Generates post-incident timelines from log data automatically
• Maintains an incident database with trend analysis across quarters

Automation Level: 🟡 AI-ASSISTED

Human makes escalation decisions. Human decides whether an incident is “significant” under §33 NIS2UmsuCG. Human approves BSI notifications. The agent prepares everything — the human decides and sends.

ISO 27001:2022 Mapping: A.5.24 (Information security incident management planning), A.5.25 (Assessment and decision on information security events), A.5.26 (Response to information security incidents)

BSI IT-Grundschutz: DER.2.1 (Behandlung von Sicherheitsvorfällen)

Agent Type: Incident Response Agent

---

(c) Business Continuity and Crisis Management

What NIS2 requires: Business continuity management including backup management, disaster recovery, and crisis management to ensure availability and restoration of systems after an incident.

What an AI agent does:

• Automates Business Impact Analysis (BIA) data collection by pulling system dependency maps, RTO/RPO values, and availability metrics
• Monitors backup job completion, retention compliance, and recovery test schedules
• Tracks DR plan currency — flags when plans reference decommissioned systems or outdated contacts
• Runs tabletop exercise scheduling and tracks completion rates
• Generates continuity readiness dashboards with real-time RTO achievement data

Automation Level: 🟡 AI-ASSISTED

BIA data collection and monitoring is automated. But crisis decisions — activating a DR plan, declaring a crisis, prioritizing recovery order during an actual incident — require human judgment. The Krisenstab decides, not the algorithm.

ISO 27001:2022 Mapping: A.5.29 (Information security during disruption), A.5.30 (ICT readiness for business continuity), A.8.13 (Information backup)

BSI IT-Grundschutz: DER.4 (Notfallmanagement)

Agent Type: Business Continuity Agent

---

(d) Supply Chain Security

What NIS2 requires: Security measures relating to the relationship between the entity and its direct suppliers or service providers, including vulnerability handling and cybersecurity requirements in contracts.

What an AI agent does:

• Maintains a vendor risk inventory with automated questionnaire distribution and response tracking
• Monitors vendor security posture continuously — SSL ratings, breach databases, dark web mentions, financial stability indicators
• Tracks fourth-party risk: who your vendors depend on (concentration risk in cloud providers, shared SaaS dependencies)
• Scans vendor contracts for required NIS2 clauses (incident notification obligations, audit rights, subcontractor controls)
• Alerts when a vendor appears in breach notifications (e.g., via Have I Been Pwned enterprise feeds or sector-specific ISACs)

Automation Level: 🟢 CONTINUOUS MONITORING

ISO 27001:2022 Mapping: A.5.19 (Information security in supplier relationships), A.5.20 (Addressing information security within supplier agreements), A.5.21 (Managing information security in the ICT supply chain)

BSI IT-Grundschutz: OPS.2.1 (Outsourcing für Kunden)

Agent Type: Vendor Risk Agent

What stays human: Vendor selection decisions, contract negotiations, relationship management, termination decisions.

---

(e) Security in Network and Information Systems Acquisition, Development, and Maintenance

What NIS2 requires: Security in the acquisition, development, and maintenance of network and information systems, including vulnerability handling and disclosure.

What an AI agent does:

• Integrates into CI/CD pipelines to enforce security gates (SAST, DAST, SCA scan results)
• Tracks vulnerability disclosure timelines — time from discovery to patch across all systems
• Monitors patch compliance across the asset inventory, flagging systems outside SLA
• Reviews change requests for security implications by cross-referencing affected systems with the risk register
• Maintains a vulnerability disclosure process tracker per ISO 29147

Automation Level: 🟡 AI-ASSISTED

Scanning and tracking is automated. But decisions about accepting vulnerability risk, prioritizing patches against business constraints, and approving architectural changes require human expertise. A security architect reviews — the agent tracks.

ISO 27001:2022 Mapping: A.8.25 (Secure development life cycle), A.8.8 (Management of technical vulnerabilities), A.8.9 (Configuration management)

BSI IT-Grundschutz: OPS.1.1.3 (Patch- und Änderungsmanagement), APP.6 (Allgemeine Software)

Agent Type: DevSecOps Agent

---

(f) Policies and Procedures for Assessing Effectiveness of Cybersecurity Risk-Management Measures

What NIS2 requires: Policies and procedures to assess the effectiveness of the cybersecurity risk-management measures — essentially, testing whether your controls actually work.

What an AI agent does:

• Runs automated control testing on schedule: Are firewall rules still configured correctly? Is logging still enabled on all critical systems? Are access reviews happening on time?
• Collects control evidence automatically from source systems (screenshots, config exports, log samples)
• Tracks control effectiveness metrics over time — pass/fail rates, mean time to remediate failed controls
• Generates audit-ready evidence packages mapped to specific Article 21(2) requirements
• Identifies control degradation trends before they become findings

Automation Level: 🟢 CONTINUOUS MONITORING

This is where AI agents shine brightest. Control effectiveness assessment is inherently a monitoring and data-collection task. The agent tests, measures, and reports. Humans interpret strategic implications and approve remediation plans.

ISO 27001:2022 Mapping: A.5.36 (Compliance with policies, rules, and standards), 9.1 (Monitoring, measurement, analysis, and evaluation)

BSI IT-Grundschutz: DER.3.1 (Audits und Revisionen)

Agent Type: Compliance Monitoring Agent

---

(g) Basic Cyber Hygiene Practices and Cybersecurity Training

What NIS2 requires: Basic cyber hygiene practices and cybersecurity training for all staff, with specific emphasis on management body awareness per Article 20(2).

What an AI agent does:

• Tracks training completion rates per department, role, and seniority — flags overdue personnel
• Monitors phishing simulation results: click rates, report rates, repeat offenders, trend lines
• Tracks Geschäftsführer/Vorstand training completion separately (Article 20(2) requires management body training specifically)
• Generates hygiene scorecards: password policy compliance, endpoint protection coverage, software update status
• Identifies departments with declining security awareness metrics for targeted intervention

Automation Level: 🟢 CONTINUOUS MONITORING

ISO 27001:2022 Mapping: A.6.3 (Information security awareness, education, and training), A.5.10 (Acceptable use of information and other associated assets)

BSI IT-Grundschutz: ORP.3 (Sensibilisierung und Schulung zur Informationssicherheit)

Agent Type: Security Awareness Agent

What stays human: Training content creation, in-person workshops, Betriebsrat coordination for monitoring activities.

---

(h) Policies and Procedures Regarding Use of Cryptography and, Where Appropriate, Encryption

What NIS2 requires: Policies and procedures on the use of cryptography and encryption to protect the confidentiality, authenticity, and integrity of data.

What an AI agent does:

• Maintains a complete cryptographic inventory: algorithms in use, key lengths, certificate expiry dates, protocol versions
• Monitors all public-facing SSL/TLS certificates — alerts 30/14/7 days before expiry
• Scans for deprecated algorithms (SHA-1, DES, RC4, TLS 1.0/1.1) across the environment
• Tracks crypto policy compliance: are all data-at-rest encryption requirements met? Are key rotation schedules followed?
• Monitors for quantum-readiness gaps as post-quantum cryptography standards mature (NIST FIPS 203/204/205)

Automation Level: 🟢 CONTINUOUS MONITORING

ISO 27001:2022 Mapping: A.8.24 (Use of cryptography)

BSI IT-Grundschutz: CON.1 (Kryptokonzept)

Agent Type: Security Assessment Agent

What stays human: Cryptographic policy decisions, algorithm selection for new systems, key management governance.

---

(i) Human Resources Security, Access Control Policies, and Asset Management

What NIS2 requires: Human resources security measures, access control policies, and asset management — covering the full lifecycle from onboarding through role changes to offboarding.

What an AI agent does:

• Runs automated access reviews: compares actual permissions against role-based access control (RBAC) baselines, flags deviations
• Monitors for orphaned accounts — detects when HR terminations don’t trigger corresponding AD/IdP deprovisioning
• Tracks asset inventory completeness: devices without owners, unmanaged endpoints, shadow IT indicators
• Correlates access patterns with job role data to detect privilege creep and excessive permissions
• Generates Joiner/Mover/Leaver compliance reports with SLA tracking

Automation Level: 🟡 AI-ASSISTED

Access reviews are automated in data collection and anomaly detection. But access decisions — should this person retain this permission? — require business context that humans provide. The Betriebsrat may also have co-determination rights (§87 BetrVG) over monitoring systems involved in access control.

ISO 27001:2022 Mapping: A.5.15 (Access control), A.5.16 (Identity management), A.5.18 (Access rights), A.6.1 (Screening), A.6.5 (Responsibilities after termination), A.5.9 (Inventory of information and other associated assets)

BSI IT-Grundschutz: ORP.2 (Personal), ORP.4 (Identitäts- und Berechtigungsmanagement)

Agent Type: IAM Governance Agent

---

(j) Use of Multi-Factor Authentication or Continuous Authentication Solutions

What NIS2 requires: Use of multi-factor authentication (MFA) or continuous authentication solutions, secured voice/video/text communications, and secured emergency communication systems where appropriate.

What an AI agent does:

• Monitors MFA enrollment rates across all identity providers — flags users and service accounts without MFA
• Detects MFA bypass events and fallback authentication usage
• Tracks MFA method strength: distinguishes between SMS (weak), TOTP (acceptable), and FIDO2/passkeys (strong)
• Monitors for authentication anomalies: impossible travel, new device registrations, brute force attempts
• Generates MFA coverage reports per system, department, and user type (internal, external, privileged)

Automation Level: 🟢 CONTINUOUS MONITORING

ISO 27001:2022 Mapping: A.8.5 (Secure authentication)

BSI IT-Grundschutz: ORP.4 (Identitäts- und Berechtigungsmanagement)

Agent Type: IAM Governance Agent

What stays human: MFA policy exceptions, method selection strategy, user experience trade-offs.

The Compliance Gap Reality

The math is straightforward. A 90% reduction in compliance monitoring time doesn’t mean you fire your compliance team. It means your 1.5-person team can actually cover NIS2 + GDPR + ISO 27001 + TISAX without burning out.

What AI agents will never do:

• Strategic risk decisions — the Geschäftsführung defines risk appetite, not an algorithm
• Betriebsrat engagement — works council coordination for monitoring tools requires human negotiation under §87 BetrVG
• Board presentations — the CISO presents to the Vorstand, the agent prepares the data
• Regulatory interpretation — when the BSI issues new guidance, humans interpret and adapt
• Audit defense — when the auditor asks “why did you accept this risk?”, a human answers

BSI Reporting Integration

The NIS2 reporting cascade is one of the most operationally demanding requirements. Here’s how an Incident Response Agent handles it:

Within 24 hours — Early Warning (Frühwarnung) The agent detects the incident via SIEM correlation, classifies severity, and drafts an early warning in BSI-compliant format. It pre-fills: incident category, affected systems, estimated impact scope, initial IoCs. A human reviews, confirms classification as “significant” (erheblicher Sicherheitsvorfall), and approves submission to the BSI portal.

Within 72 hours — Incident Notification (Meldung) The agent compiles the full notification: updated impact assessment, attack vector analysis (MITRE ATT&CK mapped), affected service scope, cross-border impact indicators, containment status. It pulls data from ticketing systems, SIEM logs, and threat intel feeds automatically. Human reviews, adds strategic context, approves.

Within 1 month — Final Report (Abschlussbericht) The agent generates a comprehensive timeline from first indicator to full containment. It compiles: root cause analysis data, remediation actions taken, lessons learned (mapped back to Article 21 controls), and effectiveness metrics of the response. This becomes both BSI-compliant and internally useful for the next management review.

The difference: without an agent, each of these reports takes 4–8 hours of manual compilation under extreme time pressure. With an agent, the human spends 30–60 minutes reviewing and approving pre-generated content.

From Quarterly Snapshots to Continuous Compliance

NIS2 Article 21 isn’t asking for anything revolutionary. Risk management, incident handling, business continuity, supply chain security — these are established disciplines. What’s new is the scope (far more entities covered), the accountability (management body personal liability under Article 20), and the reporting speed (24-hour initial notification).

AI agents address the operational reality: too many requirements, too few people, too little time. Six of ten Article 21(2) requirements can run under continuous automated monitoring. The remaining four get AI-assisted workflows that reduce manual effort by 80–90%.

The result isn’t compliance theater. It’s a compliance team that actually sleeps at night.
