Mapping your IT landscape: a cornerstone of cybersecurity

Cyber threats are everywhere - and increasingly sophisticated

Cybersecurity is no longer just a technical issue - it’s a strategic one. Threats can come from any direction:

• A human error like phishing or misconfiguration,
• A vulnerability in applications or infrastructure,
• Physical intrusion into premises,
• Or an indirect breach via suppliers or third-party systems.

In today’s landscape, the question is not if you will face an attack, but when. Being prepared is the only sustainable response - and having the right tools is key.

Mapping your IT and organisational landscape

IT mapping today goes far beyond static inventories. It’s about creating a living model of your entire ecosystem: applications, data flows, infrastructure, teams, roles, and processes.

This integrated view helps you understand dependencies, anticipate risks, and manage your digital assets effectively - across both technical and business domains.

Before the attack: preventing and reducing risk exposure

An up-to-date, structured IT map helps you:

• Identify critical and outdated assets;
• Spot vulnerabilities and areas of technical debt;
• Reduce your attack surface by eliminating redundant or unsecured systems;
• Structure business continuity plans (BCPs) based on actual dependencies.

It also supports rationalisation efforts - reducing system complexity and improving resilience.

During the attack: enabling real-time crisis management

When a cyberattack occurs, every second counts. IT mapping becomes a crucial tool to:

• Visualise real-time interdependencies and active data flows;
• Isolate compromised systems and contain lateral movement;
• Identify impacted stakeholders and critical business processes;
• Support clear, actionable communication between IT, security teams, executives, and regulators.

It provides shared, understandable visuals - even for non-technical crisis team members.

After the attack: rebuilding with confidence

Once the immediate crisis is resolved, your IT map continues to deliver value by:

• Guiding recovery priorities through visibility into key systems and dependencies;
• Supporting post-incident reviews and audits;
• Feeding into continuous improvement efforts;
• Preserving institutional knowledge - especially important during staff turnover or onboarding.

It becomes a strategic asset for resilience and long-term governance.

A compliance enabler

IT mapping isn’t just about operational efficiency - it’s increasingly a regulatory requirement:

• NIS2 demands detailed knowledge of critical systems and dependencies;
• DORA imposes rigorous risk visibility across financial IT environments;
• Frameworks like ISO 27001 and GDPR require clear documentation of data processing and protection mechanisms.

A robust, live IT map makes it easier to produce required documentation, pass audits, and demonstrate a mature cybersecurity posture.
