Cloud security

Chetan Yeddula has played a pivotal role in advancing cybersecurity innovation at Cisco from 2021 to 2024, with a sharp focus on Security Service Edge (SSE), API security, and cloud automation. His efforts have elevated the scalability, enforcement precision, and cloud-readiness of Cisco's security solutions, directly impacting their speed, resilience, and enterprise adoption.

Between 2022 and 2024, as a lead engineer in Cisco’s SSE product line, Chetan designed and delivered Object-as-a-Service (OaaS)—a scalable, low-latency security framework that allows the creation and management of thousands of security objects with real-time enforcement. His architecture reduced latency by 40% and was completed in just three months, earning executive-level recognition. He also introduced automation for cloud policy deployment using CI/CD and Infrastructure-as-Code, cutting manual effort by 70% and enabling zero-downtime updates across AWS, Azure, and GCP environments. His geolocation-based policy enforcement further helped global enterprises comply with region-specific regulations.

From 2021 to 2023, during his time with Cisco’s APIX Management Platform team, Chetan led efforts to reinforce API security and governance across Cisco Umbrella. He developed a comprehensive API management layer integrating advanced authentication and authorization mechanisms, including OAuth2, JWT, RBAC, mTLS, and federated identity protocols like SAML and OpenID Connect. He also introduced an automated API deployment pipeline leveraging Kong and OpenAPI, reducing release timelines by 70% while implementing custom validators to enforce compliance and security standards.

Through his architectural contributions, Chetan has strengthened Cisco’s security infrastructure, enabling high-performing, compliant, and resilient solutions for enterprise customers. His work continues to shape how modern security frameworks are built, scaled, and maintained in cloud-native environments.
