Our Story
Founded by Practitioners.
Built for Every Organization.
APPSECREW was born from a simple observation: organizations of all sizes face serious security challenges, but elite security expertise has historically been reserved for those with enterprise-sized budgets. We built APPSECREW to change that.
We are a team of offensive security practitioners — with deep roots in application security, adversary simulation, and the rapidly evolving world of AI security. Our work spans penetration testing and red team operations through to securing LLMs, agentic AI systems, and ML pipelines. Everything we do is shaped by real-world attack experience and a genuine commitment to making clients more secure, not just more compliant.
As AI becomes embedded in every product and pipeline, we recognized early that traditional security tooling wasn't built for it. APPSECREW's AI security practice brings the same offensive rigour we apply to applications and infrastructure — to the frontier of machine intelligence.
Our Mission
Security Shouldn't Be a Luxury.
Too many organizations treat security as an afterthought — a compliance checkbox to be completed before a funding round or an audit. We believe security should be embedded in how you build, how you operate, and how you grow.
APPSECREW was founded to bring practitioner-grade security expertise to organizations that need it most — regardless of whether they have a 30-person security team or a single developer wearing too many hats. We scale our approach to match your reality.

Our Capabilities
Where We Go Deep
Two areas define our practice — offensive security and AI security. They are distinct disciplines, but both demand the same adversarial mindset.
Core Capability
Offensive Security
We think like attackers — because many of us have been. Our offensive security practice covers the full spectrum of adversarial testing: web and API penetration testing, network exploitation, mobile application security, and full red team operations modelled on real threat actor TTPs aligned to MITRE ATT&CK.
Red teaming isn't just a penetration test with extra steps. It's a long-horizon simulation of the adversaries that actually target your sector — testing whether your people, processes, and technology can detect, respond to, and contain a determined attacker. We don't just find vulnerabilities; we build end-to-end attack chains that demonstrate real business impact.

- Red Team Operations (MITRE ATT&CK Aligned)
- Social Engineering & Physical Security
- Purple Team Exercises & Detection Validation
- Adversary Simulation & Crown Jewel Testing
Emerging Practice
AI Security
As organizations race to deploy LLMs, agentic workflows, and ML pipelines into production, a new and poorly understood attack surface has emerged. Traditional security tools weren't built for it — and most security teams haven't tested it.
APPSECREW's AI security practice applies offensive security rigour to the full AI stack: prompt injection and jailbreaking, agentic system abuse, model extraction, RAG knowledge poisoning, and pivoting from AI-layer vulnerabilities into backend infrastructure. We also partner with AiSecurityAcademy.ai to deliver AI security training and certifications.

- AI Red Teaming & Jailbreak Campaigns
- Agentic AI & Tool Exploitation
- RAG & Knowledge Base Security
- ML Pipeline & Model Supply Chain Audits
What We Stand For
Our Values
Root Cause, Not Band-Aids
We don't just enumerate vulnerabilities. We help you understand why they exist and how to architect your systems so they don't come back.
Honest, No-Fluff Advice
We're practitioners first. No inflated scopes, no unnecessary work. If a $5,000 assessment is what you need, we'll say so — even if we could sell you more.
Quality Over Quantity
Every engagement is led by a senior engineer. We don't run junior analysts on client work. The person scoping is the person testing.
All Sizes, All Sectors
Security shouldn't be a luxury for only well-funded enterprises. We work with startups, scale-ups, and enterprises with the same level of care and expertise.
What We Do
Our Practice Areas
From application security assessments to full red team operations — every service is delivered by senior practitioners with real-world attack experience.
