Reliance Cyber launches RADAR on Google Cloud platform

Reliance Cyber has launched RADAR, an agentic security operations platform built on Google Cloud and integrated with Google Security Operations.

The UK managed detection and response provider says the platform is designed for enterprise security teams facing high alert volumes and pressure to demonstrate cyber resilience. It combines agent-assisted triage, detection engineering and a natural-language customer portal in a single service layer.

Before launch, Reliance Cyber ran RADAR across every alert in its security operations centre over the past year. It says that produced 99.3% precision in AI-assisted alert classification across its highest-volume alert sources, covering more than 18,000 cases.

The platform also identified about 3,000 tuning opportunities across more than 10,000 production SIEM rules. Reliance Cyber presents those figures as evidence that security operations can move away from manual alert handling towards more automated processes with human oversight.

Platform design

According to Reliance Cyber, RADAR brings together four specialist agents in a single orchestration layer. They cover detection engineering, threat triage, response orchestration and autonomous self-healing, with staff monitoring and managing the system.

The platform sits above Google Security Operations and is intended to coordinate its components while presenting results to customers in a more accessible form. It will also support integrations with other major security vendors from launch.

The customer-facing element includes a customised portal with a natural-language AI assistant. Reliance Cyber says the assistant is grounded in each customer's alerts, incidents and threat intelligence. The portal also includes unified dashboards, real-time intelligence feeds and security posture recommendations.

The platform extends beyond core security operations centre data to include areas such as vulnerability management and cloud security. That reflects a broader push by providers to present security operations through a single interface rather than through separate tools and reports.

Google relationship

Reliance Cyber says its relationship with Google Cloud underpins the platform. It describes Google Cloud as supporting its specialist AI agents as the business shifts from what it calls AI-enabled administration with humans in the loop towards expert human oversight of AI agents.

That approach reflects a wider debate in cyber security over how far automation should drive investigations and response. Vendors and service providers have increasingly argued that large alert volumes, expanding attack surfaces and growing vulnerability exploitation make manual-only approaches difficult to sustain.

Alex Martin set out the company's case for the model.

"In security operations, customers are not buying AI, agents or automation; they are buying outcomes: faster response, lower risk and a transparent security operation they can actually understand. We have spent a year running AI in production and measuring everything. The next twelve months are about putting that capability directly into our customers' hands, on top of the world-class Google Security Operations stack, under expert human oversight. The winners of the next decade of MDR will be the providers that can turn leading security platforms into measurable outcomes for customers - with speed, transparency and expert control," said Alex Martin, Managing Director, Reliance Cyber.

Workforce shift

As the platform goes live, Reliance Cyber says its analyst team is changing roles in parallel. Experienced analysts are moving away from handling lower-level alerts and towards orchestrating investigations, detection engineering and incident response, with more direct customer engagement.

That shift reflects a broader trend in managed security services, as providers try to use automation to reduce repetitive operational work while moving staff into higher-level analysis and advisory tasks. Whether that model delivers better outcomes at scale remains a key question for buyers assessing new security operations platforms.

Jenny Kalenderidis, who chairs the company, described the launch as a major step for the business.

"RADAR reflects our confidence in the team, the technology and the market opportunity. It is the most significant evolution of Reliance Cyber's service since the company was founded, and we are delivering it from the UK, with a British engineering and analyst team," said Jenny Kalenderidis, Executive Chair, Reliance Cyber.
