Penetration Testing
— attackers actually behave

Manual, adversary-led testing across web, API, cloud, identity, mobile and AI systems — scoped to the threat model, reported for engineers and the board, retested until fixed.

Status quo · late 2026

What has changed — and why it matters now

From annual test to continuous

PTaaS platforms and attacker-driven automation mean a test is a stream, not an event. Buyers now ask for retest SLAs and live dashboards, not a PDF.

Identity is the new perimeter

Most real intrusions are token theft, consent phishing, device-code abuse and Entra/AD attack paths — so we test identity like an adversary, not a scanner.

AI systems are in scope

Prompt injection, tool abuse via MCP servers, RAG data exfiltration and agent privilege escalation are now standard test cases (OWASP LLM Top 10, MITRE ATLAS).

How we approach it

Our method for Penetration Testing

01Threat-model the scopeCrown jewels, likely adversaries, and the attack surface that matters — external, internal, cloud, SaaS, AI.

02TestBlack / grey / white-box; manual exploitation chained to business impact; safe by rules of engagement.

03Report for two audiencesReproducible findings for engineers; risk narrative and heat-map for leadership; CVSS 4.0 plus exploitability.

04Fix & retestRemediation workshops, verification retests, and a trend line across cycles.

In depth

Engagement types

External & internal infrastructure

Perimeter, segmentation, lateral movement, privilege escalation.

Web, API & mobile

OWASP ASVS / API Top 10, business-logic abuse, auth flows, GraphQL, mobile storage.

Cloud & Kubernetes

IAM misconfiguration, metadata abuse, container escape, CI/CD secrets, storage exposure across AWS, Azure, GCP.

Identity (AD / Entra ID)

BloodHound attack paths, Kerberos abuse, token replay, Conditional Access gaps, hybrid sync weaknesses.

AI / LLM red teaming

Prompt injection, jailbreaks, tool and MCP abuse, RAG poisoning and data exfiltration — PyRIT, Garak, custom harnesses.

Red & purple team

Objective-based adversary emulation against your SOC, with detection engineering feedback.
