Attackers don't move
in a straight line.
Neither do we.
Expert-led penetration testing, red teaming, and threat modeling built around how attackers actually gain access, escalate privileges, move through environments, and reach what matters.
Let us relay through your environment before they do.
Expert-led offensive security designed to identify how vulnerabilities connect, where attackers can move, and which weaknesses create meaningful risk to the business. Select a service below to learn more.
Web Application & API Penetration Testing
Deep manual testing of web applications, APIs, authentication flows, authorization controls, sessions, business logic, and application-layer attack paths. Testing goes beyond automated scanning to identify weaknesses that require an attacker’s perspective to uncover.
AI & LLM Penetration Testing
Adversarial testing of AI-enabled applications, LLM integrations, agents, RAG workflows, and AI-assisted business processes. Testing can include prompt injection, indirect prompt injection, jailbreak resistance, authorization weaknesses, insecure tool use, excessive agency, data exposure, and model abuse.
External Penetration Testing
Assessment of Internet-facing infrastructure, applications, services, and exposed attack surface to identify vulnerabilities that could provide an external attacker with an initial foothold into the organization.
Internal Network Penetration Testing
Simulates an attacker operating from inside the environment after obtaining an initial foothold. Testing focuses on credential exposure, privilege escalation, lateral movement, segmentation weaknesses, sensitive systems, and paths toward high-value assets.
Active Directory Penetration Testing
Identifies weaknesses across Windows and Active Directory environments including credentials, permissions, trusts, delegation, privilege relationships, configuration weaknesses, and attack paths that could lead to elevated access or domain compromise.
Red Team / Adversary Simulation
Objective-driven adversary simulation designed to evaluate how people, technology, processes, identity, and security controls respond to realistic attack chains. Engagements are tailored around defined objectives rather than isolated vulnerabilities.
Threat Modeling
Structured analysis of systems, applications, architectures, and workflows to identify trust boundaries, high-value assets, credible attacker paths, abuse cases, and security controls before weaknesses become exploitable.
Wireless Penetration Testing
Testing of wireless networks, authentication mechanisms, segmentation, encryption, client behavior, rogue access opportunities, and pathways from wireless environments into internal systems.
Connected Infrastructure & Device Penetration Testing
Security testing of connected operational technology and enterprise devices such as kiosks, payment terminals, cameras, access-control systems, digital signage, printers, scanners, IoT devices, and other network-connected infrastructure.
Payment Environment & PCI Segmentation Testing
Testing of payment environments, POS infrastructure, network segmentation, access controls, and isolation of systems that process or interact with cardholder data. Engagements can support PCI DSS penetration-testing and segmentation-testing requirements.
Physical Penetration Testing
Authorized testing of physical security controls, facilities, access procedures, and opportunities for an attacker to gain unauthorized access to restricted areas, systems, devices, or sensitive information.
Social Engineering Assessment
Controlled social engineering exercises designed to evaluate human-layer security controls and organizational resilience against realistic phishing, impersonation, pretexting, and related attack techniques.
Vulnerability Assessment & Exploit Validation
Identification and validation of vulnerabilities across systems and infrastructure, with emphasis on separating theoretical findings from weaknesses that represent credible and actionable security risk.
Direct Senior Expertise.
The expert helping scope your engagement is the expert performing the work.
Relay is built around deep manual testing, adversarial thinking, clear communication, and practical remediation guidance — without sales handoffs that can dilute technical depth.
From discovery to defense.
A focused engagement model built around finding how attackers can move, transferring the intelligence that matters, closing the path, and validating that the environment is stronger.
Discover the Path
Identify how vulnerabilities connect and where an attacker can actually move through the environment.
Relay the Intelligence
Transfer the attack path, impact, priorities, and remediation guidance directly to the people responsible for reducing risk.
Break the Path
Remove the weaknesses and connections that enabled the attacker to continue moving toward high-value systems or objectives.
Validate the Defense
Retest remediation and confirm the original path to compromise — and related avenues of attack — have been closed.
Real environments.
Real attack paths.
Modern attack surfaces extend far beyond a single application or network. Relay evaluates the connections between identities, infrastructure, applications, devices, facilities, payment environments, and the people who operate them.
Tested where
it matters.
Experience spans Fortune 50 and large-enterprise environments across complex, highly connected, and highly regulated industries.
A vulnerability rarely exists in isolation. What matters is where it can take an attacker next.
Let's Relay.
Whether you need a focused penetration test, threat model, or broader adversary simulation, Relay helps determine where you're exposed, what can actually be exploited, and what should be fixed first.
