Red Teaming
A penetration test examines systems. Red teaming tests the entire organization–technology, processes, and people. We proceed exactly like a real attacker with a specific goal: to break in, gain access to sensitive assets, and remain undetected for as long as possible.
Request red teamingWhat is Red Teaming?
Red teaming is the most comprehensive way to test an organization’s cybersecurity. Unlike a classic penetration test, which focuses on a predefined scope, red teaming has no fixed boundaries. It has a goal–a so-called flag, i.e., a critical organizational asset: access to a customer database, a domain controller, or protected internal systems.
Our team works just like a sophisticated APT (Advanced Persistent Threat) group. We use a combination of techniques:
Technical exploits – vulnerabilities in infrastructure, networks, and applications
Social engineering – phishing, vishing, and employee manipulation
OSINT – collection of publicly available information about the organization
Physical infiltration – entering company premises and gaining access to devices
The goal is not just to find technical vulnerabilities. Red teaming reveals how your organization responds to a real attack–whether the security team notices the threat, how quickly they react, and where the weaknesses lie in both processes and the human factor.
When do you need Red Teaming?
Red teaming is not for everyone–and that is okay. It is intended for organizations that have basic security measures in place and want to know if they actually work. Consider it if any of the following points apply:
You have completed penetration tests
You have fixed vulnerabilities and want to know if the organization is truly resilient to targeted attacks.
Your organization is growing
People, systems, and the supply chain are increasing. With every change, the attack surface grows.
You must meet legal obligations
The Cybersecurity Act (No. 264/2025 Coll.) and Decree No. 409/2025 Coll. require regulated service providers under the higher obligation regime to evaluate the effectiveness of implemented measures at least once a year.
You have an internal SOC or blue team
You want to verify whether your analysts actually detect and stop an attack in real time.
Management wants tangible evidence
Not a checklist report, but a real attack simulation with a clear result: we came, we got in, and this is how it can be fixed.
You are planning an acquisition, merger, or migration
Red teaming before a major change reveals risks that would otherwise only manifest too late.
Types of Red Teaming
Depending on what you want to verify, we choose one of three scenarios–or a combination thereof:
Virtual Red Teaming (online)
An attack conducted exclusively remotely via digital channels. We focus on network infrastructure, servers, cloud environments, web and internal applications, email, and VPNs. It also includes spear-phishing and vishing targeted at specific employees. Suitable for organizations with distributed work and cloud-first environments.
Physical Red Teaming
We simulate an attacker’s physical access to the organization’s premises. We use techniques such as tailgating (entering behind an authorized person), cloning access cards, impersonation, planting infected USB devices, and physical access to server rooms, printers, or unprotected workstations. It reveals security gaps that an IT audit will never uncover.
Assumed Breach
A scenario in which we skip the initial intrusion and start at the point where the attacker is already in your internal network. We simulate the attacker’s behavior after gaining access: lateral movement through the network, privilege escalation, access to sensitive data, persistence, and covering tracks. Ideal for organizations that want to specifically test the detection and response capabilities of their security team or SOC.
How does Red Teaming work?
Red teaming is a structured process, not an improvised attack. Every project goes through these phases:
Definition of goals and rules
Together, we define the target assets (flags), Rules of Engagement, scope, timeframe, and communication protocols. We sign an NDA and a Statement of Work. We do not start without this foundation.
Reconnaissance
Passive collection of information about the organization from publicly available sources. We map employee email addresses, technologies used, subdomains, social media exposure, and job advertisements that reveal internal technologies.
Attack Phase
Active attack using all agreed-upon vectors: exploitation of technical vulnerabilities, phishing campaigns, physical entry attempts, and social engineering. We map techniques according to the MITRE ATT&CK framework.
Lateral Movement and Escalation
After the initial intrusion, we continue deeper into the network: searching for other systems, escalating privileges, and moving toward the target assets. We monitor when–and if at all–your security team detects us.
Output and Debriefing
We prepare a detailed report and present the results to your team, including a Blue Team debrief–a joint analysis of where gaps in detection and response were identified.
What will you receive as output?
The output of a red teaming engagement is significantly richer than a standard pentest report. You will receive:
A detailed technical report – a complete description of every step of the attack, the techniques and tools used, including evidence
Executive summary – a concise, non-technical summary for company management and the board of directors
Attack timeline – a chronological overview from reconnaissance to goal achievement, including moments when the attack was detected
Mapping to MITRE ATT&CK – each technique categorized within the industry framework for easier reporting
Prioritized recommendations – specific remediation steps ordered by criticality, no generic advice
Presentation and debriefing – a personal meeting explaining the results to both the technical and management teams

What sets us apart
Specialized team, not subcontractors
We are not a consultancy firm that resells work. Every project is led directly by members of our team with full responsibility for the result.
Manual work, not just automated tools
Automated scanners detect known vulnerabilities. Logic errors, business-logic flaws, and exploit chains can only be uncovered by an experienced tester who thinks like an attacker.
Actionable outputs
The report is not an academic exercise. It is written so that your dev or ops team can start remediation immediately–with specific steps and links to resources.
Tailored scenarios, not templates
We build every project according to your environment, your risks, and your goals. We do not use off-the-shelf methodologies or generic templates.
Discretion and confidentiality
We sign an NDA before every project. All information and results remain exclusively between us and you.
Compliance with international standards
The methodology is based on OWASP, PTES, and NIST and is in compliance with NIS2 and the Cybersecurity Act–meaning it is recognized by regulators and auditors.
Frequently Asked Questions
A penetration test has a predefined scope–we test specific systems, applications, or a network. Red teaming has no fixed boundaries: it has a goal (flag) and the team reaches it by any legal means–technically, physically, or via the human factor. Red teaming tests the entire organization, not just its IT.
A standard red teaming engagement lasts 2 to 6 weeks depending on the scope, complexity of the environment, and the number of attack vectors. Assumed Breach scenarios may be shorter. We will propose a precise schedule after the initial consultation.
We recommend it for organizations that have basic security measures in place–firewall, EDR, access management–and want to know if they can withstand a real attacker. Typically, these are companies with 50+ employees, critical infrastructure operators, financial institutions, healthcare, and regulated service providers under ZoKB/NIS2.
A scenario in which we assume that an attacker has already gained initial access to your network–for example, via a compromised account or device. We skip the external reconnaissance phase and focus on what happens next: can your security team defend against an attacker who is already inside? It is a very effective way to test internal network segmentation, SOC detection capabilities, and incident response plans.
Detailed step-by-step technical documentation of the attack, an executive summary for management, an attack timeline, mapping to MITRE ATT&CK, a list of identified vulnerabilities with prioritized recommendations, and a remediation roadmap. A presentation of the results to your team is also included.
Yes–we conduct it exclusively based on written consent and a contract with the client. The Rules of Engagement precisely define what we are and are not allowed to do. All activities are coordinated to ensure no downtime for production systems. We work in accordance with Czech law and European legislation.
Decree No. 409/2025 Coll. to the Cybersecurity Act requires regulated service providers under the higher obligation regime to evaluate the effectiveness of their information security management system at least once a year–i.e., to prove that measures are effective, not just implemented. Red teaming provides NÚKIB and internal auditors with the strongest possible evidence: a real attack simulation with documented results.
