Delivering Virtual CISO Services and End-to-End Cybersecurity for a Leading SEBI-Regulated Stock Brokerage

A leading SEBI-regulated stock brokerage, ranked among India's top 50 brokerage firms, required a strategic cybersecurity partner to manage its end-to-end security and regulatory compliance program. Operating in a highly regulated financial environment with security expectations comparable to leading online brokerage platforms, the organization needed continuous security oversight, proactive risk management, and expert guidance to safeguard its digital infrastructure.

Securis360 was engaged under a long-term annual cybersecurity contract to serve as the organization's Virtual Chief Information Security Officer (vCISO), taking ownership of cybersecurity strategy, regulatory compliance, incident readiness, application security, and cyber resilience.
