Adversary Simulation

Testing Security the Way Real Attackers Do

We conduct adversary simulation and penetration testing to evaluate how real-world attackers could compromise systems, users, and facilities. Our engagements are designed to mirror realistic attack paths—providing clear insight into exploitable weaknesses and how defenses perform under real conditions.

Our work spans internal and external environments, applications, wireless networks, social engineering, and physical access testing. Each engagement is scoped deliberately, executed responsibly, and documented with evidence-based findings and practical remediation guidance.

Actionable Outcomes from Real-World Attack Simulation

Our adversary simulation and penetration testing engagements are designed to show how attackers could realistically compromise environments—and what that means in practice. Each engagement focuses on evidence, attack paths, and control effectiveness, not theoretical risk. Testing is performed responsibly and documented clearly to support remediation, validation, and leadership decision-making.

Exploitable Weaknesses Identified

Gaps across systems, applications, users, or physical controls are identified using real-world attack techniques. 

Attack Path Validation

Individual weaknesses are chained together to demonstrate how meaningful impact could be achieved.

Control Effectiveness Measured

Existing security controls are evaluated based on their ability to detect, prevent, or respond to simulated adversary activity.

Clear Remediation Guidance

Practical, prioritized recommendations are delivered with evidence gathered during testing.

Internal & External Network Attack Simulation

Real-world attackers rarely rely on a single weakness. Network-based adversary simulation evaluates how external exposure, internal trust, and misconfigurations can be combined to gain meaningful access. Testing focuses on how an attacker could move from initial access to lateral movement and privilege escalation—highlighting where controls fail and where detection gaps exist.

External Attack Paths

We test externally exposed services and systems to identify weaknesses that could enable initial access.

Privilege Escalation

Attack techniques are used to assess how quickly elevated access could be achieved within the environment.

Internal Network Exploitation

Internal testing evaluates segmentation, credential exposure, and opportunities for lateral movement once access is obtained.

Realistic Impact Demonstration

Findings illustrate not just vulnerabilities, but how they can be chained to reach sensitive systems or data.

Web Application & Cloud Attacks

Applications and cloud services often present direct paths to sensitive data and privileged access. Adversary simulation in this area evaluates how authentication flaws, authorization gaps, and logic weaknesses could be abused in real-world scenarios.

Application Exploitation

We test custom and third-party web applications for authentication, authorization, and business logic flaws.

Account & Identity Attacks

Attack paths targeting identities, roles, and access controls are simulated to assess exposure and impact.

Cloud & SaaS Abuse

We evaluate cloud services and SaaS platforms for misconfigurations, excessive permissions, and token or session abuse.

Data Access & Impact Validation

Findings demonstrate how application or cloud weaknesses could lead to data exposure or broader compromise.

Wireless & Physical Access Attacks

Wireless networks and physical access controls often provide overlooked entry points into otherwise well-defended environments. Adversary simulation in this area evaluates how proximity-based access and on-site weaknesses could be leveraged to gain network or system access. Testing is conducted in a controlled manner and scoped to assess realistic exposure without disrupting operations.

Wireless Network Exploitation

We evaluate wireless configurations for unauthorized access, weak authentication, and the presence of rogue access points.

Network Pivot Opportunities

Testing examines how wireless or physical access could be used to pivot into internal systems or sensitive network segments. We focus on realistic movement paths rather than isolated access.

On-Site Access Testing

Physical controls are assessed to determine how easily restricted areas, devices, or network connections could be accessed. Where appropriate, we simulate real-world entry conditions.

Real-World Entry Scenarios

Findings demonstrate how physical and wireless weaknesses could enable broader compromise when combined with other attack paths.

Social Engineering & User Exploitation

Human behavior remains one of the most effective attack vectors. Adversary simulation in this area evaluates how social engineering techniques could be used to influence users, obtain credentials, or gain unauthorized access. Engagements focus on realistic scenarios designed to measure exposure and response without creating unnecessary disruption.

Phishing & Pretexting Attacks

We use targeted phishing and pretexting techniques to evaluate user susceptibility and detection effectiveness in realistic scenarios.

Detection & Response Validation

User-driven attack activity is assessed to determine how quickly and effectively it is identified and addressed. We examine how alerts escalate and translate into action.

Credential Capture & Abuse

Testing examines how compromised credentials could be used to access systems or escalate privileges. We focus on exposure paths and downstream impact, not isolated credential loss.

Behavioral Risk Insight

Findings highlight where training, controls, or response processes can be strengthened to reduce human-driven risk. We present results in a form leadership and security teams can act on.
