Cyrex Protoceptor™
Man-in-the-Middle Penetration Testing for the Communication Layer
Most vulnerabilities don't live in your UI - they live in the communication layer. If an attacker can intercept, manipulate, replay, or forge traffic between your client and server, your security controls are already compromised. We step into the flow and break the code before attackers do.
If an attacker can intercept, manipulate, replay, or forge traffic between client and server, your security controls are already compromised.

Why Traditional MitM Testing Isn't Enough
Most security tools are built for web applications; they focus exclusively on HTTP/HTTPS inspection. That works for websites, but it fails against modern, high-performance systems.
It does not work for:
Protoceptor intercepts everything:
Attackers do not limit themselves to web traffic. Neither do we.
Protoceptor intercepts and manipulates any network traffic, not just browser-based communication.
If your system communicates over a network, Protoceptor can step into it.
What Cyrex Protoceptor Actually Does
Protoceptor allows our engineers to step directly into live communication flows and actively tamper with traffic to validate security architecture.
Intercept live traffic
Step into communication between client and server
Modify packets in transit
Alter data, payloads, and protocol messages
Replay traffic sequences
Test authentication and session handling
Inject malicious payloads
Validate input validation and sanitization
Bypass client-side validation
Test server-side security controls
Test encryption implementation
Validate cryptographic security
Validate integrity controls
Test data tampering protections
Assess authentication logic
Identify session and token vulnerabilities
Manual exploit validation
Real attacker behavior simulation
We don't scan. We don't rely on automation.
We manually validate exploit paths through active tampering. This is how real attackers operate.
Protoceptor is the instrument. Pair Hacking is the force.
Tools don't secure systems; engineers do. Every Protoceptor engagement utilizes our signature Pair Hacking methodology.
Pair Hacking Methodology
Minimum two security engineers per engagement
This simulates coordinated attacker behaviour — not solo testing.
Protoceptor is the instrument. Pair hacking is the force multiplier.
What We Test in the Communication Layer
Protoceptor validates the security controls that protect your network communication
Authentication & Session Handling
Data Integrity
Encryption & Transport Security
Anti-Cheat Bypass
Traditional anti-cheat focuses on memory and client integrity.
If gameplay authority lives client-side, we will find it.
The Protoceptor Workflow
Clear structure. No ambiguity.
Passive Phase - Reconnaissance
We analyze architecture, networking stack, protocol behaviour, authentication flows, and backend services. This defines attack surface and scope.
Active Phase - Target Penetration
This is where Protoceptor operates at full capacity. Our engineers intercept live traffic, manipulate packets, escalate exploit chains, validate impact, and attempt real abuse scenarios.
Reporting - Debrief & Remediation
You receive full vulnerability documentation, reproduction steps, risk severity classification, real exploit scenarios, and remediation guidance aligned to your architecture.

Frequently Asked Questions
Identify Network-Layer Exploits Before Attackers Do
If an attacker can manipulate traffic, your economy can be exploited, your gameplay can be forged, and your backend trust assumptions collapse.
Protoceptor identifies these weaknesses before they are weaponized in production.
