We find the breach before the attacker does.
Arrnock Security is a premier penetration testing firm helping organizations navigate an era of sophisticated threats — uncovering the invisible cracks in your infrastructure and delivering a strategic roadmap for resilience.
Security testing across every layer of your environment
From cloud configuration to Active Directory hardening, our security engineers assess the systems modern organizations depend on most.
Cloud Security Testing
Microsoft Azure and AWS security testing and configuration review, assessing identity, storage, and network controls.
Active Directory
AD DS implementation review and security testing to close privilege-escalation and lateral-movement paths.
Network Security
Implementation and testing of switch, router, and next-gen firewall configurations against real attack paths.
Web-Based Pentesting
Manual assessment of web applications for logic flaws, auth bypasses, and cross-site request forgery.
App Security Pentesting
Application-layer testing including full API security assessments across authorization and data exposure.
MFA & Firewall Audits
MFA vulnerability assessments and firewall policy audits across on-premise and cloud environments.
Penetration testing built for how attackers actually work
Every engagement is carried out by hand by our own operators — across web, API, network, cloud, AI systems, and people. No scanner reports repackaged as findings.
Web App Pentesting
We go past surface-level scans, manually chaining logic flaws, auth bypasses, and business-logic abuse that automated tools consistently miss.
Manual-firstAPI Pentesting
We map every endpoint in your architecture and test authorization, rate limiting, and data exposure the way an attacker would probe them.
Endpoint-mappedNetwork Pentesting
Internal and external network assessments that emulate a real intruder — from initial foothold to lateral movement and privilege escalation.
Internal + externalAI/LLM Pentesting
We assess machine learning pipelines and AI-powered products for prompt injection, data leakage, and misuse paths unique to these systems.
Emerging threatsCloud Pentesting
AWS, GCP, and Azure environments assessed from the outside in, including assumed-breach scenarios that test what happens after initial access.
AWS · GCP · AzureSocial Engineering
Phishing, pretexting, and physical-access simulations that test the human layer — often the fastest way into an otherwise hardened network.
Human layerTrusted by security-conscious teams
