Penetration Testing, Red Teaming & AI Red Teaming
We simulate attacks before real threats strike, for organisations across Europe and worldwide.
Our certified experts simulate real-world breaches to expose hidden risks before they become real problems.

Globally recognized certifications that prove our offensive security expertise






Offensive Security With Purpose. Precision. Proof.
We are a specialist team focused solely on offensive security. Our mission is simple: help you uncover and remediate weaknesses before adversaries can exploit them.
From large enterprises to growing startups, we serve organizations that take security seriously. Every assessment we deliver is guided by real-world attack scenarios, deep technical knowledge, and globally recognized certifications.
Whether it’s a full red team simulation or targeted penetration testing, we tailor every engagement to mirror real-world adversaries. Our capabilities include Threat-Led Penetration Testing (TLPT), Adversary Simulation, AI/ML Red Teaming, and advanced assessments across infrastructure, applications, and cloud environments. Each test is intelligence-led, manually executed, and aligned with industry standards and frameworks such as MITRE ATT&CK, MITRE ATLAS, DORA, TIBER-EU, CREST, OWASP, PCI-DSS, HIPAA, NIST SP 800-53, NCSC Guidance, CIS Benchmarks, and ISO/IEC 27001. We focus on delivering actionable insights—not noise.

Threat-Led Penetration Testing
Simulations driven by threat intel and aligned with DORA, TIBER-EU, CBEST, and STAR.

Red Team Engagements
Realistic attack simulations to test detection, defense, and incident response.

AI/ML Red Teaming
Test your LLM apps, AI agents and models against prompt injection, data leakage, jailbreaks and real-world abuse.

Applications Penetration Testing
Real-world testing for real-world apps: web, mobile, APIs, thick clients, and beyond.

Internal & External Infrastructure Testing
Identify vulnerabilities across your internal and external networks before attackers do.
Cloud Security Assessments
Detect risks in cloud deployments, from configurations to lateral movement paths.
Security That Scales. Numbers That Prove It.
Our numbers reflect the depth of our expertise, the trust of our clients, and the real-world impact of our engagements. Behind every figure is a story of threat emulation, security hardening, and resilience built. Each year we deliver 150+ penetration tests, every engagement is 100% senior-led, we have identified 500+ vulnerabilities for our clients, and reports arrive within 48 hours.

How We Work With You
We built our own platforms so working with us is simple, transparent and secure. Flint, our scoping and onboarding platform, takes you from first request to signed statement of work. Slate, our reporting platform and client portal, delivers your findings and reports. You and your colleagues sign in with your company SSO, see every project in one place and download reports whenever you need them.
Flint and Slate are developed by our sister company Pentest Project (pentestproject.com). We host a dedicated instance for you in the region you prefer. Sign in with Microsoft Entra ID, Google Workspace or any OpenID Connect provider, or use two-step sign-in. Your administrator decides which colleagues see which projects.

Across Europe and worldwide, remotely or on-site. Most of our clients are European organisations, including EU-regulated financial entities preparing for DORA.
Yes. We act as the red team provider for threat-led penetration testing (TLPT) under DORA, TIBER-EU and national TIBER programmes, as well as UK CBEST and STAR-FS. New to TLPT? Start with our free DORA TLPT guide.
Yes. Our AI/ML red teaming covers LLM applications, AI agents, RAG pipelines and machine learning models. We test for prompt injection, jailbreaks, data leakage and tool abuse, mapped to the OWASP Top 10 for LLM Applications and MITRE ATLAS.
Senior consultants, on every engagement. Our testers individually hold CREST, OSCP+, PNPT, CARTE (Certified Azure Red Team Expert) and AI red teaming certifications. As a company, PenTest Hub is ISO/IEC 27001 and ISO 9001 certified.
It depends on your scope. Tell us what you need in Flint, our scoping platform, and your answers become a precise effort estimate, price and statement of work that you can review and sign online.
It depends on the size and complexity of your scope. We confirm the effort and dates in your statement of work before any testing begins.
Within 48 hours of testing finishing. Every finding is prioritised by business risk, with evidence and clear remediation guidance your team can act on.
Yes. Every client gets access to Slate, our reporting platform and client portal. Read findings with evidence, track remediation, request retests and download reports as PDF, Word or Excel, all signed in with your company SSO.
Retests are agreed per contract. They can be built into a framework agreement or scoped separately for a single engagement, and you can request a retest for any finding directly in Slate.
Where you choose. We host a dedicated Flint and Slate instance for you in your preferred region, for example within the EU, so your data stays where your policies require.
Pentest Project is our sister company. It builds Flint and Slate, the scoping and reporting platforms we use with every client.
