Realistic Attacks — for a Realistic Assessment of Your Security

Technically secure systems alone are not enough. Only under realistic attack conditions can you determine how resilient your organization truly is. CERTAINITY simulates targeted attacks against your infrastructure, employees, physical security controls, and security processes — combining Open Source Intelligence (OSINT), social engineering, DDoS testing, and physical security assessments.

Whether you require a comprehensive Red Team Assessment or a focused engagement targeting specific attack vectors, our goal is to identify weaknesses and help you strengthen your defenses.

We test whether your organization can withstand a real-world attack — and show you how to improve your resilience.

Our Services at a Glance

A full Red Team engagement simulates a real attack by an external team — without prior knowledge or notification of the Blue Team (e.g. your internal security team). The objective is to evaluate your detection capabilities, security controls, response procedures, and overall cyber resilience.

Typical phases:

  1. Reconnaissance (OSINT and intelligence gathering)
  2. Initial Access (e.g. phishing or physical intrusion)
  3. Lateral Movement & Privilege Escalation
  4. Objective Achievement (e.g. data exfiltration or access to critical systems)

This assessment focuses specifically on the initial stage of a sophisticated cyber attack: bypassing your perimeter defenses. External systems, employees, or physical locations are targeted to gain initial access to your internal environment.

Key focus areas:

  1. Technical and physical reconnaissance
  2. Perimeter attacks (e.g. web applications, VPNs, exposed services)
  3. Social engineering, (spear) phishing, and vishing
  4. Physical intrusion into buildings and restricted areas (“physical breach”)
  5. Documentation of the initial compromise of internal systems

This engagement assumes that an attacker already has access to an internal system (e.g. a compromised workstation with standard user privileges). The objective is to evaluate your organization’s ability to detect lateral movement, privilege escalation, and attacker objectives.

Typical phases:

  1. Privilege Escalation
  2. Evasion of EDR and SIEM solutions
  3. Lateral Movement
  4. Targeted access to sensitive systems or data

Analysis of publicly available information about your organization to assess your external attack surface and identify potential attack opportunities.

Typical sources include:

  1. Technical information (e.g. domains, certificates)
  2. Social media platforms and employee information
  3. Company registers and public authority databases
  4. Dark web and data leak sources
  5. Technical reconnaissance through scanning and enumeration

The findings directly support Red Team engagements, external penetration tests, and social engineering assessments.

Recurring phishing campaigns using realistic scenarios to measure and improve employee security awareness.

Our services include:

  1. Design and execution of tailored phishing campaigns
  2. Analysis of email opens, clicks, and credential submissions
  3. Practical recommendations for improving security awareness

Assessment of your organization’s resilience against psychological attacks — conducted remotely or on-site.

Typical attack techniques include:

  1. (Spear) phishing, vishing, and smishing
  2. Tailgating and physical intrusion
  3. Impersonation, pretexting, and USB drops
  4. Psychological manipulation and trust exploitation

Evaluation of physical security controls through controlled intrusion attempts. Often performed in combination with Red Teaming or Social Engineering engagements.

Typical attack vectors include:

  1. Bypassing access control systems
  2. Entry through secondary entrances, windows, or emergency exits
  3. Circumventing alarm or surveillance systems
  4. Remaining undetected or leaving the premises unnoticed

Controlled denial-of-service simulations to evaluate the resilience of your infrastructure, based on the internationally recognized DDoS Resiliency Score (DRS) methodology.

Typical process:

  1. Selection of suitable target systems
  2. Execution of realistic DDoS attack scenarios (e.g. IoT botnets)
  3. Assessment of the effectiveness of existing protection measures
  4. Recommendations for optimization and documentation for audit purposes

CERTAINITY conducts all attack simulations based on established frameworks (e.g. MITRE ATT&CK, DRS, and OSSTMM), in full compliance with applicable legal requirements and tailored to your organization’s objectives.

Together, we define the scope, objectives, constraints, and escalation procedures — ensuring meaningful results while minimizing operational risk.
