About Us

Spakto Cyber Labs is a specialist offensive security and penetration testing firm headquartered in Kolkata, India with operations spanning the EU and Asia-Pacific. We exist for one purpose: to find and exploit security weaknesses in our clients' infrastructure before real-world adversaries do. Our engagements simulate the tactics, techniques, and procedures (TTPs) of advanced persistent threats, giving organisations a ground-truth view of their risk posture.

Our assessment team comprises OSCP, OSCE, and CRTP certified security engineers with deep expertise across network penetration testing, web and mobile application security, cloud infrastructure (AWS, Azure, GCP), Active Directory attack paths, and red team operations. Every engagement is backed by original research — from zero-day discovery and custom exploit development to proprietary tooling that goes beyond off-the-shelf scanners. We operate with full-scope rules of engagement, delivering actionable intelligence that security teams can act on immediately.

Spakto is also at the forefront of AI-augmented security. We integrate large language models into our reconnaissance workflows, leverage RAG-based knowledge bases for rapid threat correlation, and develop AI-assisted fuzzing and exploit generation pipelines. This allows us to operate at a speed and depth that traditional consultancies cannot match — identifying complex attack chains across hybrid environments in a fraction of the time.
