Challenge
Plugging security gaps with effective controls across IT-OT systems.
Following the acquisition of a global energy firm, our client faced sub-optimal IT security policies, disparate processes, and redundant legacy systems, posing a threat to its business performance. Employee efficiency was also impacted due to the underutilization of available resources. Further, the lack of real-time centralized threat visibility resulted in a longer turnaround time in identifying and responding to cyber threats, poor user experience, and increased cyber risk. The client needed effective security controls across its IO-OT systems to plug these security gaps.
Solution
A centralized, automated identity access management and security solution to mitigate cyber threats.
We deployed managed security services across the client’s IT and OT ecosystems to build an integrated defense. And to improve user experience, we prepared a multi-year roadmap centered on integrating processes and technologies, automating security operations, and identity and access management processes.
By implementing a scalable identity and access management solution, we helped the client harmonize 11 disparate systems into a single system of records and establish automated user provisioning to grant access to applications for 25,000 users. TCS also led initiatives to identify privileged accounts and align them to role-based access control (RBAC) and disable unused active accounts.
Further, we helped the energy company conduct POCs to proactively identify threats to various security products and also improved their patch management process.
The solution helped the client harmonize 11 disparate systems into a single system of records and establish automated user provisioning to grant access to applications based on roles and permissions for 25,000 users.
Benefits
Mitigating advanced threats with consistent security enforcements and holistic guardrails.
The energy company improved its security posture with an integrated defense of IT-OT ecosystems. TCS’ solution, powered by advanced security analytics, provided them with centralized visibility into potential threats and vulnerabilities across IT-OT systems. The transformation significantly reduced the time to detect and respond to threats.
Key benefits:
30% increased security operations center maturity
40% more operational stability
1.3% false positive rate, down from 50%
40% overall risk reduction
