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.

Engagement Model

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.

01 / WEB

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-first
02 / API

API Pentesting

We map every endpoint in your architecture and test authorization, rate limiting, and data exposure the way an attacker would probe them.

Endpoint-mapped
03 / NETWORK

Network Pentesting

Internal and external network assessments that emulate a real intruder — from initial foothold to lateral movement and privilege escalation.

Internal + external
04 / AI & LLM

AI/LLM Pentesting

We assess machine learning pipelines and AI-powered products for prompt injection, data leakage, and misuse paths unique to these systems.

Emerging threats
05 / CLOUD

Cloud Pentesting

AWS, GCP, and Azure environments assessed from the outside in, including assumed-breach scenarios that test what happens after initial access.

AWS · GCP · Azure
06 / HUMAN

Social Engineering

Phishing, pretexting, and physical-access simulations that test the human layer — often the fastest way into an otherwise hardened network.

Human layer
