Threat detection is the ongoing process of identifying, analysing, and responding to malicious activities or vulnerabilities in an organisation’s network. In the realm of cyber security, threat detection plays a vital role in detecting risks before they can be exploited.
At its core, threat detection and response involves using tools, software and systems that continuously monitor environments, identify unusual behaviour, and initiate mitigations.
Why Threat Detection Matters for Modern Cyber Security
With the threat landscape constantly evolving, advanced persistent threats, insider risks, identity-based attacks businesses cannot rely solely on perimeter or signature defences. Modern organisations need a comprehensive threat detection system that covers endpoints, networks, identities, cloud workloads and adapts to new methods of attack.
CyTAL provides bespoke cyber security threat detection solutions that combine automated monitoring, behavioural analytics, and advanced testing of systems via tools like fuzz testing (see below).
The Four Methods of Threat Detection
If you’ve ever asked, “What are 4 methods of threat detection?”, here are core approaches organisations commonly utilise:
- Signature-Based Detection – Uses known threat signatures (malware hashes, known indicators) to spot threats.
- Anomaly-Based Detection – Flags deviation from normal baseline behaviour (network traffic, user actions).
- Heuristic / Rule-Based Detection – Applies rules or algorithms to detect suspicious patterns that may not match known signatures.
- Behavioural / User-Entity Behaviour Analytics (UEBA) – Monitors how users and systems behave, and detects misuse of identities, insider threats, lateral movement.
CyTAL integrates all of these into its advanced threat detection offering, delivering broad visibility and proactive detection across the enterprise.
AI in Threat Detection: The Next Level
Artificial intelligence is transforming how we detect threats. With AI-powered threat detection and AI-driven threat detection, CyTAL uses machine learning models to learn from large datasets and detect new and emerging threats in real time.
This AI layer reduces noise, improves accuracy, and shortens response times helping organisations respond to valid threats faster, and avoid swamping their teams with false positives.
Fuzz Testing and Protocol Inspection with Protocrawler
Beyond monitoring, strong threat detection also includes testing systems before they’re compromised. CyTAL’s tool Protocrawler enables fuzz testing of network protocols, allowing organisations to identify vulnerabilities and misconfigurations in systems and endpoints. Fuzz testing is a proactive technique feeding unexpected, malformed or random data into protocols to uncover weaknesses that attackers might exploit.
By including fuzz testing in the threat detection strategy, your organisation isn’t just waiting for threats it’s testing for them. Protocrawler adds depth to CyTAL’s threat detection software stack and helps strengthen your security posture before a breach occurs.
Identity Threat Detection and Insider Threats
Many breaches stem from identity misuse or insider behaviour. With identity threat detection and response, the focus is on protecting digital identities, monitoring for unusual logins, privilege escalations, credential misuse.
Similarly, insider threat detection addresses risks from employees or contractors both malicious and accidental. CyTAL’s combined strategy of monitoring, identity analytics and proactive fuzz testing gives you a layered defence.
Choosing the Right Threat Detection Tools and Software
Selecting the proper threat detection tools is key. CyTAL offers an integrated threat detection system combining:
- Continuous real-time monitoring across endpoints, cloud and network
- Behavioural analytics (for insider and identity-based risks)
- AI-powered detection to surface novel threats
- Fuzz testing via Protocrawler to reveal protocol-level weaknesses
- Automated response and logging for compliance and audit readiness
This multi-layered approach ensures your organisation has a mature cyber security posture not just reacting, but proactively strengthening defences.

Related Protocols
Effective threat detection requires understanding normal protocol behavior to identify anomalous or malicious communications:
Protocols Requiring Behavioral Monitoring:
Industrial Control Systems:
- Modbus/TCP – Monitor for unauthorized write operations, unusual function codes, or out-of-bounds register access
- DNP3 – Detect malformed messages, authentication failures, or unexpected control commands
Network Infrastructure:
- ARP – Identify ARP spoofing through duplicate IP/MAC mappings or rapid cache changes
- DHCP – Detect rogue DHCP servers or DHCP starvation attacks through offer analysis
Smart Metering:
- COSEM/DLMS – Monitor for authentication anomalies or unauthorized configuration changes
Telecommunications:
- ASN.1 – Detect malformed encoding in signaling protocols
Utility SCADA:
- IEC 60870-5-104 – Identify unauthorized telecontrol commands or session anomalies
- IEC 61850 – Monitor for abnormal service invocations or data object access
Protocol-aware threat detection combines baseline behavioural analysis with deep packet inspection to identify attacks that bypass perimeter defenses. Learn how ProtoCrawler testing improves threat detection or discuss your monitoring requirements.
