Anyone responsible for maintaining an organization’s cybersecurity posture should know that detection engineering is far more effective than conventional threat hunting. Despite its clear advantages, detection engineering is not yet a universally adopted security practice, as many organizations still rely on outdated, less effective methods.

Detection engineering is the process of developing, testing, and refining methods to proactively identify cyber threats. Unlike traditional threat detection, which often relies on static signatures and pre-built rules, detection engineering is behavior-driven, context-aware, and tailored to an organization’s unique threat landscape. By combining security operations, threat intelligence, and data science, organizations can build more adaptive and resilient detection capabilities.
Every organization with valuable data, critical infrastructure, or regulatory obligations needs detection engineering. The rise in advanced persistent threats (APTs), supply chain attacks, and ransomware operations has rendered traditional reactive approaches insufficient. Organizations are increasingly realizing that detection engineering reduces dwell time, improves response capabilities, and enhances overall cyber resilience. Additionally, compliance frameworks and cyber insurance providers are placing greater emphasis on strong detection strategies.
Detection Engineering Gaining Acceptance
Enterprises with mature security operations — particularly in financial services, healthcare, technology, and critical infrastructure — are leading the way in detection engineering. These industries face heightened regulatory scrutiny and are frequent targets of sophisticated threat actors. Large organizations also have the resources to invest in dedicated detection engineering teams. However, as more tools become available, mid-sized and smaller organizations are beginning to adopt similar practices.
Yet, many organizations still lag behind — to their detriment. Some struggle to find security professionals with both threat hunting and engineering skills, as detection engineering requires expertise in coding, data science, SIEM rules, and security analytics. Beyond the talent gap, detection engineering requires continuous refinement of custom detection rules, behavior-based analytics, and automated response playbooks.
Because it requires fewer upfront changes, many companies opt for manual threat hunting instead. Additionally, the cost of implementation is a major barrier, especially for smaller organizations that may still rely on legacy security tools that lack modern detection engineering capabilities.
Advancements in Detection Engineering
Detection engineering has evolved from a niche function to a strategic priority for forward-thinking organizations. Key advancements include:
- A stronger emphasis on behavior-based detections rather than just signature-based alerts.
- The integration of threat intelligence to create detections aligned with real-world adversary tactics.
- The use of threat modeling to anticipate potential attack paths.
- Adoption of MITRE ATT&CK and D3FEND frameworks as foundational models for detection development.
Automation and AI have the potential to streamline rule creation, tuning, and event correlation. However, AI is not a silver bullet. Human expertise remains essential to refine detections, validate AI-driven alerts, and anticipate adversarial tactics that could bypass automated defenses.

AI and automation will transform detection engineering by:
- Accelerating detection development. AI can analyze vast amounts of threat data to suggest high-fidelity detection rules.
- Reducing false positives. Machine learning models can better distinguish between normal and suspicious activity.
- Enhancing threat-hunting capabilities. AI-driven analytics will help identify hidden patterns and anomalies.
- Automating response actions. Integration with Security Orchestration, Automation, and Response (SOAR) will enable faster containment and mitigation.
Best Practices for Detection Engineering
For organizations looking to build or enhance their detection engineering program, best practices include:
- Invest in the right data sources. Ensure access to logs from EDR, SIEM, identity platforms, and cloud environments to build effective detections.
- Prioritize behavior-based detections. Move beyond static signatures and focus on how attackers operate.
- Implement threat modeling. Use frameworks like MITRE ATT&CK to map detection coverage against known adversary techniques.
- Automate where possible. Leverage AI/ML for rule tuning and automation for enrichment and response actions.
- Continuously test and refine detections. Utilize adversary emulation tools like Atomic Red Team to validate effectiveness.
- Foster collaboration. Detection engineering works best when security operations, threat intelligence, and IT teams work together.
Integrating detection engineering into security operations significantly improves resilience and response capabilities against cyber threats while reducing the risk of breaches, financial losses, and reputational damage. However, no security posture is ever perfect. That’s why I strongly advocate for — the proper orchestration of a system of immutable data backups — ensuring backups cannot be altered, deleted, or encrypted. Consequently, cybersecurity providers can offer the assurance of a rapid and complete recovery from compromised and encrypted data in the event of a breach.
