Our TDIR services
We provide a range of specialized threat detection, investigation and response (TDIR) services. These services can be tailored to your specific requirements, offering flexible and scalable solutions to enhance your security and resilience.
Managed detection and response (MDR)
AI-powered security, unmatched resilience. Our MDR services provide round-the-clock protection, detection and response to cyber threats across your digital environment. Benefit from our decades of deep industry expertise for AI-driven security management and reduced downtime – all seamlessly integrated with your existing technology stack.
Managed endpoint detection and response (MEDR)
Minimize the impact of breaches and protect your endpoints from advanced threats. Our MEDR services deliver enhanced threat detection, investigation and response, giving you full visibility and control over your devices while minimizing attacker dwell time. Available as a standalone service or fully integrated within MDR.
Digital forensics and incident response (DFIR)
Rapid, expert-led response when every second counts. Our global DFIR teams combine forensic expertise with local presence to investigate and contain sophisticated threats. Services include emergency response, proactive compromise assessments, and incident response retainers – available on demand, 24/7.
Attack surface management
Uncover hidden exposures. Our attack surface management (ASM) services provide a unified view of your external attack surface, highlighting infrastructure vulnerabilities (EASM & Vulnerability Management) and broader digital risks (DRPS). We help you achieve comprehensive visibility to prioritize threats, optimize security resources, and protect critical business assets.
Incident preparedness
Limit the impact of cyber incidents by proactively strengthening your cyber resilience. Our customized exercises – from strategic tabletop discussions to technical cyber drills and immersive cyber range simulations – prepare your teams for effective response and recovery. Tailored cyber recovery plans and crisis simulations with communication playbooks ensure preparedness for any cyber disruption.
Threat hunting
Our CERT-led threat hunting services proactively identify hidden threats through expert analysis and intelligence. Unlike automated solutions, our team utilizes hypothesis-driven investigations informed by frontline experience, threat intelligence, and behavioral analysis to uncover malicious activity that might otherwise be missed.
Cyber threat intelligence
Go beyond standard threat feeds. We deliver curated and contextualized insights drawn from diverse sources tailored to your industry and infrastructure. Far from offering generic data, we equip you with actionable intelligence to anticipate threats and inform security decisions based on attacker motivations and tactics.
