XDR Complete Tier

End-to-end monitoring and response

Our XDR Complete Tier service includes onboarding customers to Google SecOps SIEM, SOAR, and Google Threat Intelligence (GTI), providing 24/7/365 monitoring and response.

Through our investment in automation and threat intelligence, we deliver rapid Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR). Our platform-agnostic approach means we can integrate almost any technology environment – including bespoke or legacy systems – with minimal disruption.

Managed cyber threat intelligence, powered by Google

Our Cyber Threat Intelligence service blends the best of Google Threat Intelligence Enterprise+, a powerful fusion of Mandiant, VirusTotal, and Google’s proprietary intelligence, into a fully managed solution.

We onboard customers into Google’s External Attack Surface Management (EASM) and continuous monitoring tools, alerting them immediately to new exposures, vulnerabilities, misconfigurations, or the presence of sensitive data online, including on the Dark Web.

Expert deployment and risk assessments via Google SecOps

Our Professional Services team supports customers in deploying and optimising the Google SecOps portfolio. This includes integration of customer log sources, creation and fine-tuning of SIEM detection rules, and development of SOAR playbooks to automate response.

We also deliver first and third-party risk assessments using Google Threat Intelligence (GTI) and External Attack Surface Management (EASM) to give organisations visibility into their risk posture and supply chain exposure.

Complementary services that enhance Google Security

To further enhance our customers’ cybersecurity maturity, we offer a suite of managed and specialist services that integrate seamlessly with Google’s security stack:

Managed Network Security – Managing firewalls and other network security devices to strengthen cyber resilience and further reduce MTTD/MTTR.
Vulnerability Management and Patching – Using best-in-class scanning tools and automation to identify vulnerabilities and apply patches quickly and efficiently.
Digital Forensics and Incident Response (DFIR) – A retainer based service to help organisations contain, investigate, and recover from security incidents with confidence.
