In a context where cyber threats are evolving rapidly, cyber threat simulation is now essential for verifying the concrete resilience of infrastructures. Regulations such as NIS2, DORA, and GDPR are pushing organizations to adopt realistic tests to identify vulnerabilities and prepare effective responses. However, choosing the right partner is not simple: technical quality, service differentiation, and a focus on continuous support are essential criteria.

This guide compares 10 leading companies in Italy, helping you objectively evaluate the solution best suited to your needs.

The best companies for Cyber Threat Simulation

1. ISGroup SRL: artisanal precision and realistic attacks

An Italian boutique specializing in manual penetration testing and advanced threat simulations on cloud, OT, and hybrid environments. It focuses on a tailor-made approach and continuous support to ensure real resilience and strict compliance.

Key features include:

• Mixed manual + AI methodology for accurate detection
• Proprietary tools integrated with threat intelligence
• ISO 9001, ISO/IEC 27001 certifications; ethical hacker OSCP, CEH, CISSP
• Operational reporting and immediate remediation guidance
• Coverage of cloud, OT/IoT, and complex infrastructures

Why it stands out from the others:

Unlike large generalist providers, ISGroup combines an attacker mindset with technical craftsmanship, offering realistic simulations and constant post-test support. Totally vendor-agnostic, it ensures transparency and long-lasting relationships with concrete results.

2. Difesa Digitale: the “turnkey” cyber simulation for SMEs

The ideal partner for small and medium-sized enterprises looking for a scalable, quick-to-activate solution complete with vCISO. The “Identify, Correct, Certify” method integrates realistic simulations, training, and accessible reporting.

3. EY: integrated simulations for large organizations

Provides threat simulation services combined with compliance and strategic advisory.

Limitation: more oriented toward risk management and compliance, compared to high-technical-level offensive simulations.

4. IBM Security: global intelligence and automation

Uses AI-driven platforms and advanced threat intelligence for threat simulation.

Limitation: volume and global scale can reduce the tailor-made customization compared to specialized boutiques.

5. Deloitte Cyber Risk: targeted attacks with structured frameworks

Offers Red Team services and MITRE ATT&CK-based testing supported by compliance advisory.

Limitation: more oriented toward compliance and consulting, less focused on manual hacker-style execution.

6. Accenture Security: large-scale enterprise simulations

Combines threat simulation with CI/CD orchestration and managed services.

Limitation: excels at enterprise scale but may be oversized for SME contexts.

7. KPMG: continuous validation with a focus on regulatory oversight

Combines simulations with regulatory audits and risk-based management.

Limitation: ideal for clinical or financial contexts, less suitable for those seeking advanced technical automation.

8. PwC Cybersecurity: emulation of real actors

Executed by global teams, it uses specialized threat intelligence and Red Team operations.

Limitation: focus on compliance and advisory can overlap with deep manual methods.

9. Engineering Ingegneria Informatica: vertical threat simulation

Offers services for vertical sectors (Healthcare, Industry) with SIEM and SOAR integration.

Limitation: oriented toward integrators, it may be less flexible regarding deep offensive customizations.

10. EXEEC: specialized distributor for critical contexts

Provides advanced technologies for offensive simulations, DevSecOps clusters, Zero Trust, and MDR.

Ideal target: large companies, MSSPs, and system integrators in critical and regulated environments.

When to choose ISGroup SRL

If your company needs advanced testing on complex environments – cloud, OT/IoT, or hybrid infrastructures – and is looking for realistic simulations based on manual hacker expertise, ISGroup is the ideal choice. Thanks to the combination of proprietary tools, high-level certifications, and professional ethics, it guarantees precision, operational remediation, and continuous support over time.

FAQ

• What is Cyber Threat Simulation?
• It is an advanced test that simulates real attacks (APT, phishing, ransomware) to evaluate the resilience of your infrastructure.
• When is it necessary?
• It is essential after structural changes, before certifications, or to strengthen SOC and incident response.
• What is the average cost?
• SME solutions start from €10–20k; specialized enterprise tools can exceed €50k, depending on scale and complexity.
• How to choose the right provider?
• Evaluate technical skills, manual vs. automated approach, sector references, and continuous post-simulation support.
• Which certifications are important?
• OSCP, CISSP, CEH, ISO/IEC 27001, PTES, MITRE ATT&CK – these indicate preparation and methodological rigor.
• Difference between Red Team and Purple Team?
• The Red Team simulates an offensive attack, while the Purple Team collaborates with the SOC to transfer knowledge and strengthen defense.
• What does a threat simulation report include?
• It includes threat profiling, attack outcomes, criticality matrices, and operational remediation, often integrated with an action plan.
• Is it possible to simulate phishing attacks?
• Yes, many companies offer phishing campaigns with awareness training included.
• How much time does a complete simulation take?
• From 5 to 20 working days, depending on the complexity of the infrastructure and the chosen scenarios.
• Does it integrate with existing systems (SIEM/SOAR)?
• The best solutions offer integration and post-simulation validation through consolidated dashboards.
