"Our goal is clear: make enterprise AI security technically rigorous, locally relevant, and practical to deploy."
AltaySec was founded as enterprises began deploying chatbots, RAG pipelines, and AI agents faster than their security practices could adapt. We focus on that gap: testing AI-specific attack surfaces, protecting production LLM traffic, and helping teams manage human and data risk.
With Türkiye-based engineering and independent research, we provide LLM penetration testing, AI red teaming, Guardian runtime protection, AltayPrisma phishing simulation, and corporate AI security training.
Building the Future with Youth: AltaySec is not just a consultancy firm. We offer all our academy tools, sandboxes, and research completely free to cybersecurity students across Turkey. Because we know that sovereignty in the cyber homeland is only possible with a well-trained and dedicated generation.
Our Values
National Engineering
Local and independent expertise that understands the unique needs of Turkish enterprises and supports digital sovereignty.
Research Discipline
Products and services are informed by technical findings, open publications, datasets, and applied laboratory work.
Technical Focus
Our work centers on LLM application security, AI red teaming, runtime protection, and phishing resilience.
Ethics & Transparency
We state scope, assumptions, limitations, and evidence clearly so organizations can make informed security decisions.

AltaySec Founder · AI Security Researcher
Technical work spanning prompt injection, RAG security, AI agent attacks, and OWASP LLM Top 10.
In-person LLM Security and AI security training at multiple organizations, including Gazi University Computer Engineering.
LLM Security, prompt injection defense, AI agent security, and OWASP LLM Top 10 — all works revolve around this axis.
AI security is a new field for Turkey. We are here to define, research, and bring this field to enterprises.

Turkish and global LLM security, prompt injection, jailbreak defense, AI red/blue teaming, and OWASP LLM Top 10 are the main areas of expertise. At AltaySec, this work connects to products, educational content, and community growth.
Helps grow AltaySec as an ecosystem: Academy, Workshop, AI Hub, Payload Bank, open tools, datasets, and community channels.
Works on both attack and defense so organizations using LLMs can reduce exposure to prompt injection, jailbreaks, and language-dependent attack surfaces.
AI security is still a new field in Turkey. The focus is to turn it into a clear security practice that institutions can understand, teams can apply, and products can support.
Treats prompt injection and jailbreak risks not as theoretical topics, but as real attack surfaces that need to connect with products, education, and daily security practice.
Works to make cybersecurity and AI security more accessible through AltaySec's education, product, and community work inside a 700+ member ecosystem.
