Introduction
Threat Hunting in ZIA: DIY vs. Done For You is a virtual webinar examining advanced threat detection methodologies within cloud security environments. The session targets cybersecurity professionals responsible for identifying sophisticated attacks that evade conventional security tools, particularly those working with Zscaler Internet Access deployments. As threat actors increasingly exploit legitimate cloud services and encrypted internet traffic to mask malicious activity, organisations face mounting pressure to develop proactive detection capabilities rather than relying solely on automated controls.
The webinar addresses a fundamental question facing security teams: whether to build internal threat hunting capabilities or leverage managed services to achieve continuous detection coverage. This decision carries significant implications for resource allocation, detection efficacy and operational maturity.
About This Event
Hosted by Zscaler, this live webinar brings together product specialists and threat research experts to explore practical approaches to threat hunting within cloud-delivered security architectures. The session runs across multiple time zones, with scheduled broadcasts for Americas, EMEA and APAC regions, allowing global security teams to participate during convenient hours.
The programme combines technical instruction with real-world intelligence, drawing on frontline observations from Zscaler’s threat research operations. Attendees will receive guidance on establishing foundational threat hunting programmes while understanding how managed services can extend these capabilities with continuous monitoring and specialist expertise.
Leveraging ZIA Telemetry for Threat Detection
Central to the webinar’s technical content is the use of Zscaler Internet Access telemetry as a data source for threat hunting operations. ZIA, functioning as a cloud-native secure web gateway within Zscaler’s zero trust architecture, processes vast quantities of internet traffic data that can reveal indicators of compromise invisible to endpoint or network-based detection tools.
The session will demonstrate how security teams can interrogate this telemetry to identify anomalous patterns, suspicious domain communications and behavioural indicators associated with advanced persistent threats. Unlike signature-based detection, threat hunting using ZIA data enables analysts to pursue hypothesis-driven investigations, searching for evidence of attacker presence based on known tactics, techniques and procedures.
This approach proves particularly valuable against attacks that deliberately avoid triggering automated alerts. Adversaries increasingly route command-and-control traffic through legitimate cloud platforms, blend malicious requests with normal business traffic, and employ encryption to obscure their activities. Telemetry from a cloud security platform positioned inline with all internet-bound traffic provides visibility that perimeter-focused tools cannot match.
Building Internal Threat Hunting Capabilities
The webinar dedicates significant attention to organisations pursuing self-managed threat hunting programmes. Building these capabilities internally offers advantages in terms of institutional knowledge, customisation to specific business contexts and direct integration with existing security operations workflows.
However, effective threat hunting demands substantial investment. Analysts require deep understanding of attacker methodologies, proficiency with query languages and investigation tools, and sufficient time free from reactive incident response duties. Many organisations struggle to maintain dedicated hunting resources when security teams face constant pressure from alert triage and compliance obligations.
The session will outline foundational elements necessary for a sustainable hunting programme, including data access requirements, hypothesis development frameworks and integration with threat intelligence sources. This practical guidance aims to help security leaders assess whether their organisations possess the prerequisites for successful internal programmes or whether alternative approaches might prove more effective.
Managed Threat Hunting as a Scaling Strategy
For organisations lacking the resources or expertise to maintain continuous hunting operations, managed services present an alternative path to advanced detection capabilities. The webinar will examine how Zscaler’s managed threat hunting service operates, providing around-the-clock detection supported by specialist analysts with deep platform knowledge.
Managed approaches address several persistent challenges in security operations. They eliminate the need to recruit and retain scarce threat hunting talent, provide coverage during nights, weekends and holidays when internal teams are unavailable, and bring external perspective informed by observations across multiple customer environments. Threats identified in one organisation can inform detection efforts across the entire customer base, creating collective defence benefits unavailable to isolated internal teams.
The trade-offs merit careful consideration. Managed services introduce dependencies on external providers, may offer less customisation than internal programmes, and require clear communication channels to ensure findings translate into effective response actions. The webinar aims to provide balanced perspective on these factors, helping attendees evaluate which model aligns with their operational requirements and risk tolerance.
Current Threat Landscape Intelligence
Beyond methodology, the session incorporates intelligence briefings on trends shaping the current threat environment. Understanding how adversaries operate informs both detection strategies and resource prioritisation decisions. The webinar will present case studies illustrating attacks that successfully bypassed traditional security controls, demonstrating the specific techniques that make proactive hunting necessary.
These real-world examples serve dual purposes: they validate the importance of threat hunting as a security discipline and provide concrete patterns that attendees can incorporate into their own detection efforts. Learning from documented intrusions accelerates capability development and helps organisations avoid repeating mistakes observed elsewhere.
Who Should Attend
The webinar is designed for cybersecurity professionals operating within medium to large enterprises, particularly those with responsibility for cloud security and threat detection programmes. Specific roles likely to benefit include:
- SOC analysts seeking to expand beyond reactive alert handling into proactive threat discovery
- Threat hunters looking to leverage cloud security telemetry in their investigations
- Security operations managers evaluating programme development options
- CISOs and IT security leaders assessing build-versus-buy decisions for advanced detection capabilities
Organisations currently using Zscaler Internet Access will find the technical content immediately applicable, though the strategic frameworks discussed have broader relevance for any security team considering threat hunting programme development.
Conclusion
As advanced threats continue to exploit gaps in automated security controls, threat hunting has evolved from an optional capability to an operational necessity for mature security programmes. This webinar offers practical guidance for organisations at various stages of that journey, whether building initial internal capabilities or evaluating managed services to achieve continuous detection coverage. The combination of methodological instruction, platform-specific technical content and current threat intelligence provides a comprehensive foundation for informed decision-making.
