Tamaghna Basu is a distinguished cybersecurity leader and entrepreneur with over two decades of experience building three ventures spanning three continents. As the Founder/CEO of DeTaSECURE, supported by In5 Dubai and Dubai Future Foundation, he pioneers innovative security solutions for Web3 and AI for enterprise clients. A Stanford University Cybersecurity Program mentor and former security lead at PayPal, Walmart, and PwC, Tamaghna has trained over 1000 professionals globally. His ventures have won 20+ international innovation awards worth $200K+ from organizations including Mastercard, Polygon, and Solana. Managing the Polygon Guild Dubai and other tech communities with 30K+ members, he bridges the gap between traditional security and emerging technologies.
The landscape has evolved dramatically from perimeter-focused security to a zero-trust architecture approach. With Web3 and AI, we’re seeing three major shifts:
First, the decentralization of security infrastructure – organizations now need to secure not just their networks but entire blockchain ecosystems. At PayPal and now with DeTaSECURE, I’ve witnessed this transition from centralized to distributed security models.
Second, AI has introduced both new threats and defensive capabilities. We’re seeing sophisticated AI-powered attacks, but also using AI for better threat detection and response. Our work with behavioral biometrics at neoEYED demonstrated this dual nature.
Third, the speed of security operations has become critical. When I was handling security at Walmart Labs, we had hours to respond. Now, with Web3 protocols, we need sub-second response times to prevent attacks.
At DeTaSECURE, we implement three key strategies:
We integrate security seamlessly into DevSecOps pipelines, enabling developers to identify and fix vulnerabilities early without delaying releases.
For Web3 projects, we conduct smart contract audits to prevent exploits while maintaining transaction efficiency.
Additionally, our Virtual CISO services ensure that cybersecurity aligns with business goals, creating strategies that strengthen security without disrupting operations.
The most crucial lessons I emphasize are:
The decentralized nature of blockchain networks makes them inherently resilient, but they’re not immune to vulnerabilities like reentrancy attacks, rug pulls, or oracle manipulation. My insight is that cybersecurity for blockchain requires two layers: protocol-level security and application-layer security. Ensuring comprehensive audits and monitoring transaction flows are essential to building trust in decentralized systems
Working with major blockchain ecosystems has taught us that:
We’ve developed a modular approach that adapts our core security services to industry-specific requirements. For example:
In finance, we focus on real-time transaction monitoring and regulatory compliance. Our experience with neoEYED, monitoring 120M+ financial transactions, taught us the importance of speed and accuracy.
For healthcare, we emphasize data privacy and HIPAA compliance while ensuring quick access to critical information.
In e-commerce, drawing from my Walmart Labs experience, we focus on fraud prevention and secure payment processing while maintaining smooth customer experience.
Our partnership with Diamante integrates our cybersecurity expertise with their blockchain infrastructure, aiming to create a secure and scalable platform for global trade. By combining blockchain’s transparency with advanced cybersecurity measures, we’re creating a trust ecosystem that can mitigate fraud while enhancing operational efficiency for users across industries.
It focuses on three key areas:
This collaboration represents the convergence of traditional security expertise with blockchain innovation, something I’ve been passionate about since my days at PayPal.
Future professionals need to master the following:
It’s a wrap-up: The future belongs to those who can bridge the gap between traditional security principles and emerging technologies.
