A True Co‑Managed Security Model
Co‑managed security is a collaborative operating model where your internal IT team works in partnership with ONGC’s dedicated cyber security specialists to protect and continuously improve your environment.
Building cyber security functionality in-house is costly and complex, which can hinder a company’s main business strategy. Co‑managed security provides a balanced approach, combining your IT team’s deep knowledge of the business with ONGC’s specialised cyber expertise, tooling, and operational frameworks.
How it works in practice
In a co‑managed model, responsibilities are clearly defined and shared:
Your IT team or MSP
Continues to manage day‑to‑day IT operations, user support, and infrastructure, maintaining control and visibility over your environment.
ONGC Cyber Security Team
Provides specialist capability across threat detection, incident response, vulnerability management, and security governance.
Shared accountability
Both teams work together through defined processes, escalation paths, and regular reporting to ensure issues are identified, prioritised, and resolved efficiently.
This creates a joined‑up security function, rather than fragmented tools or disconnected responsibilities.
24/7 Support for Mature, Cyber-Focussed Businesses
Reach Defend is designed for organisations that:
- Have an internal IT team or MSP but lack dedicated cyber security expertise
- Need 24/7 threat detection and response without building a SOC
- Want to proactively improve their security maturity, not just react to incidents
- Are working towards compliance frameworks such as the Essential Eight
- Require a trusted partner to guide and support ongoing cyber security initiatives
It is particularly suited to businesses looking to evolve from standard IT support into a structured, mature cyber security posture.
Co-managed security does not ask you to start from scratch or hand everything over. It builds on what you already have.
