Organizations invest heavily in cybersecurity technologies, security awareness training, compliance programs, and incident response capabilities. Yet many still struggle to answer a fundamental question:
Would our defenses actually stop a determined attacker?
Modern threat actors use sophisticated tactics, patience, and persistence to bypass security controls and achieve their objectives. From ransomware groups to nation-state actors, attackers rarely limit themselves to a single vulnerability or attack vector. Instead, they combine technical exploitation, social engineering, and operational security techniques to gain and maintain access to target environments.
Red Team testing helps organizations answer this question by safely simulating realistic cyberattacks against people, processes, and technology. Unlike traditional security assessments that focus on identifying vulnerabilities, Red Team engagements are designed to emulate real-world threat actors and measure an organization’s ability to prevent, detect, and respond to attacks.
A Red Team engagement or continuous Red Team service may include:
- Open-source intelligence (OSINT)
- Targeted social engineering campaigns
- External attack surface discovery and testing
- Initial access attempts
- Privilege escalation
- Lateral movement
- Security control evasion
- Operational security (OPSEC)
The result is a realistic assessment of how resilient your organization would be against the tactics, techniques, and procedures (TTPs) used by modern threat actors.
AI-Accelerated Reconnaissance and Exploitation
Both modern threat actors and red teams use artificial intelligence, including agentic AI systems, to accelerate target reconnaissance, analyze large amounts of information, identify additional attack paths, and adapt attack techniques to bypass cybersecurity defenses.
AI provides substantial additional intelligence and automation, making it increasingly important in both offensive and defensive cybersecurity operations. Red teams use these technologies responsibly and with strict safeguards to protect customer privacy and sensitive information while conducting engagements.
Red Team Testing vs Penetration Testing
The terms Red Team testing and penetration testing are sometimes used interchangeably. Regulatory frameworks such as CBEST, GBEST, and TIBER-EU refer to threat-led penetration testing (TLPT), but the testing performed is effectively a form of Red Team testing.
Despite the overlap in terminology, the two approaches differ significantly in their objectives, scope, and methodology.
A penetration test is primarily scope-based. The engagement focuses on a predefined set of systems, applications, or environments and attempts to identify and exploit as many vulnerabilities as possible. The primary goal is to discover security weaknesses.
A Red Team engagement is goal-oriented. Instead of identifying every possible vulnerability, the Red Team focuses on achieving predefined objectives that mirror real-world attacker goals. Examples include compromising Active Directory, accessing sensitive data, obtaining privileged credentials, or demonstrating the potential impact of a ransomware attack.
Penetration tests are typically conducted with the knowledge of defenders and often generate a significant number of alerts. Testing traffic may be whitelisted to prevent security controls from interfering with the assessment.
Red Team testing emphasizes stealth. Red teams actively attempt to evade detection and bypass security controls such as EDR, NDR, XDR, IDS/IPS, and SOC monitoring capabilities. This provides a more realistic assessment of how well an organization can detect and respond to advanced threats.
Benefits of Red Team Testing
Unlike traditional security assessments, Red Team testing evaluates how effectively security controls work together under realistic attack conditions.
Validation of Security Investments
Organizations can verify whether existing security controls, monitoring tools, and cybersecurity processes perform as expected against realistic attack scenarios.
Measurement of Detection and Response Capabilities
Red Team testing helps assess the effectiveness of SOC teams, incident response processes, and security technologies.
Identification of Security Gaps
The testing uncovers weaknesses that may exist between individual security controls, business processes, and employee behavior.
Executive-Level Risk Visibility
Findings demonstrate better how technical weaknesses can translate into business impact, helping leadership prioritize cybersecurity investments.
Improved Organizational Resilience
Organizations gain a deeper understanding of attacker behavior and can strengthen their defenses against future threats.
When Should Organizations Conduct Red Team Testing?
Red Team testing is particularly valuable when organizations need to validate the effectiveness of their cybersecurity defenses against realistic threats.
Common scenarios include:
- Following the deployment of a new SOC or managed detection and response service
- After significant infrastructure modernization or cloud migration projects
- Prior to regulatory assessments and audits
- Following mergers and acquisitions
- After implementing major security technologies
- To evaluate security awareness program effectiveness
- To assess resilience against ransomware and targeted attacks
- As part of a mature cybersecurity program focused on continuous improvement
Many organizations perform red team exercises annually or complement them with continuous Red Team testing to maintain ongoing visibility into their security posture.
Engagements vs Continuous Red Team Testing
Red Team testing can be performed as a time-limited engagement or as a continuous service.
A traditional Red Team engagement provides a point-in-time assessment of the organization’s security posture. It includes a one-time OSINT investigation and a limited social engineering campaign.
Continuous Red Team testing better reflects the patience and persistence of real-world threat actors. Rather than evaluating security at a single point in time, continuous testing monitors changes in the organization’s infrastructure, attack surface, personnel, and security controls. This approach includes recurring OSINT investigations, ongoing social engineering activities, and repeated attempts to achieve predefined objectives, providing a more accurate picture of long-term resilience.
Adversary Emulation
Red teams can gather threat intelligence on the tactics, techniques, and procedures used by well-known threat groups, including advanced persistent threats (APTs). Using this intelligence, the Red Team reproduces realistic attacker behavior with publicly available and custom-developed tools. Organizations can then evaluate how effectively their security controls detect and respond to specific adversary techniques.
Advanced adversary emulation often requires custom malware development capabilities to closely mirror the behavior of sophisticated threat actors.
Open-Source Intelligence
AMATAS uses open-source intelligence (OSINT) investigations to evaluate an organization’s external attack surface and collect publicly available information about employees, technologies, and exposed infrastructure.
This process may identify:
- Exposed services and systems
- Leaked credentials
- Publicly available employee information
- Third-party risks
- Dark web exposure
The intelligence gathered often serves as the foundation for subsequent social engineering and attack simulation activities.
Targeted Social Engineering Campaigns
Social engineering remains one of the most effective methods for obtaining initial access to an organization. Targeted campaigns use information gathered during the OSINT phase to create convincing phishing, spear phishing, and other social engineering scenarios.
These campaigns may evaluate:
- User susceptibility to phishing
- Credential harvesting risks
- Multi-factor authentication bypass scenarios
- Security awareness effectiveness
- Identity-based attack resilience
Assumed Breach Scenarios
In some engagements, the red team begins with a compromised user account or workstation to simulate an attacker who has already established initial access. This allows the assessment to focus on: privilege escalation, lateral movement, security control evasion, high-value asset compromise, and detection and response effectiveness.
Assumed breach scenarios provide valuable insights into what an attacker could accomplish after successfully bypassing perimeter defenses.
Active Directory Testing
Active Directory remains one of the most critical components of enterprise IT infrastructure. Because AD controls authentication and authorization across much of the environment, it is frequently targeted by both attackers and red teams. Red Team activities commonly focus on – authentication weaknesses, excessive privileges, delegation misconfigurations, credential theft opportunities, trust relationship abuse, and lateral movement pathways.
Compromising Active Directory often provides a realistic representation of the impact an advanced attacker could achieve.
Cloud Red Team Testing
Modern organizations increasingly operate hybrid environments that combine on-premises infrastructure with cloud services such as Microsoft Azure, AWS, and Google Cloud.
These environments create unique attack paths involving:
- Identity federation
- Single sign-on (SSO)
- Cross-environment trust relationships
- Cloud privilege escalation
- Cloud-to-on-premises lateral movement
Cloud Red Team testing evaluates how attackers could exploit these complex relationships to gain additional access and achieve their objectives.
Stealth and Operational Security (OPSEC)
Modern organizations deploy multiple layers of security controls, including:
- Endpoint Detection and Response (EDR)
- Network Detection and Response (NDR)
- Extended Detection and Response (XDR)
- Intrusion Detection and Prevention Systems (IDS/IPS)
- Firewalls
- SIEM platforms
- SOAR platforms
As defenses become more sophisticated, red teams must continuously evolve their operational security capabilities.
A significant portion of red team preparation focuses on developing techniques that allow them to operate stealthily, evade detection, and maintain access without triggering security alerts. This helps ensure the engagement accurately reflects the behavior of advanced threat actors.
Deliverables
A Red Team engagement is only as valuable as the insights and remediation guidance it provides. Effective reporting translates technical findings into business impact and actionable recommendations.
- Threat Intelligence Report: If OSINT or threat intelligence investigations are performed, this report summarizes the findings in a format that can be operationalized by both defensive teams and future security assessments.
- Social Engineering Report: This report provides metrics and observations from phishing and social engineering campaigns, including: email delivery rates, open rates, click-through rates, credential submission rates, and attachment interaction rates. The results help organizations measure the effectiveness of security awareness initiatives.
- Red Team Report: The primary technical report includes: executive summary, attack narrative, technical findings, business impact analysis, remediation recommendations. Mature Red Team reporting may also include – MITRE ATT&CK mapping, attack path visualization, detection coverage analysis, SOC improvement recommendations, and prioritized remediation roadmap.
Conclusion
As cyber threats continue to evolve, organizations need more than vulnerability scans and penetration tests to understand their true level of resilience. Red Team testing provides a realistic assessment of how attackers could target an organization, how effectively existing defenses can detect and stop those attacks, and where improvements are needed.
By combining technical testing, social engineering, adversary emulation, and security control validation, Red Team engagements help organizations identify weaknesses before real attackers do.
Whether conducted as a focused engagement or a continuous service, Red Team testing enables organizations to validate security investments, strengthen detection and response capabilities, and improve their overall cyber resilience against modern threats.
