Guardian Security Services

Guardian Security Services are Atech's managed security offering, combining 24/7 monitoring, investigation, response and continuous improvement to help organisations reduce cyber risk. 

Our Security Approach

Technology creates the signals. Our people turn them into action. 

Modern security tools generate thousands of alerts every day, but alerts alone don't reduce risk. Effective protection depends on the ability to detect threats, investigate every alert, respond quickly and continually improve security posture over time. 

Guardian combines your security technologies, our expert analysts and structured security operations to help protect your organisation against evolving cyber threats.

Why Guardian Security Services? 

Security operations designed to reduce risk, not just generate alerts. 

Traditional security tools can identify suspicious activity. 

Guardian transforms those alerts into action through a combination of technology, expert analysts and continuous improvement. 

  • 24/7 Security Operations Centre: Continuous monitoring, investigation and response delivered by our expert security operations team. 
  • Human-Led Security Operations: Expert analysts augmented by automation to improve detection, investigation and response. 
  • Security Posture Improvement: Assessments, recommendations and ongoing optimisation help reduce risk and strengthen security maturity. 
  • Reporting & Governance: Reporting, dashboards and service reviews provide oversight of security activity and risk. 
  • Security Remediation Support: Guardian helps organisations move from recommendation to action through remediation support and ongoing improvement activities.
