AI-Assisted Decision-Making for Security Analysts
01. Project introduction
As AI systems become increasingly embedded within cybersecurity operations, the challenge is no longer detection alone, it is interpretation.
Security analysts operate in environments shaped by:
- uncertainty
- ambiguity
- and constant cognitive pressure
Yet many security platforms continue to overwhelm users with fragmented tooling, opaque AI behaviour, and high volumes of alerts that are difficult to interpret or prioritise.
This project explored how AI could shift cybersecurity systems from passive monitoring tools into active decision-support environments. Rather than focusing solely on automation, the work examined how intelligent systems could help analysts:
- interpret threats more clearly
- investigate faster
- and make more confident decisions under pressure
The result was a shipped AI-assisted investigation experience designed to:
- reduce cognitive overload
- surface interpretable AI insights
- and support faster, more contextual threat response workflows
More broadly, the project explored a larger question:
How should humans collaborate with intelligent systems in high-risk environments where trust, speed, and judgement matter simultaneously?
02. The Problem
Modern Security Operations Centres (SOCs) face a growing imbalance between:
- the scale of incoming threat data
- the human capacity to interpret it effectively
AI systems have significantly improved threat detection capabilities, yet analysts remain overwhelmed by:
- alert fatigue
- fragmented workflows
- opaque automation
- and high cognitive load
Most platforms optimise for:
- detection accuracy
- data visibility
- and automation speed
But not necessarily:
- interpretability
- trust
- or human decision-making.
This creates a critical gap:
Analysts don't struggle to detect threats, they struggle to confidently decide what to do next.
03. Discovery and Research
Market landscape analysis
To understand how AI is currently used in cybersecurity, I conducted a review of leading industry platforms and emerging trends.
Platforms Reviewed:
- Darktrace
- CrowdStrike
- Palo Alto Networks
- Microsoft Defender
Key Observations:
- Most platforms already integrate AI for threat detection and automation
- Interfaces are often data-heavy and complex, requiring expert knowledge
- Limited transparency in AI decisions (black-box problem)
- Alert systems tend to generate high volumes of notifications, contributing to fatigue
Strengths Across the Market:
- Real-time monitoring and detection
- Strong backend AI capabilities
- Automated response features
Gaps & Opportunities:
- Poor user experience for analysts under pressure
- Lack of clear, human-readable explanations
- Limited support for decision-making workflows
Key insight:
AI in cybersecurity is not failing at detection, it's failing at decision support. Analysts don't struggle to find threats; they struggle to confidently act on them.

Data Driven Design
To understand how analysts interact with the platform and where inefficiencies occur, I used Pendo to analyse user behaviour across key workflows, including alert triage, investigation, and response. This allowed me to track how frequently features were used, how long analysts spent in each stage, and where drop-offs or delays occurred.
The data revealed that analysts were spending a disproportionate amount of time navigating between views and interpreting alert data, rather than taking action. High volumes of alerts were being opened, but only a small percentage led to meaningful action, suggesting a low signal-to-noise ratio.
Key Metrics
- Alert open rate: High volume of alerts opened per session
- Action rate: Low percentage of alerts resulting in action
- Time to investigate: Extended time spent within alert detail views
- Navigation patterns: Frequent switching between multiple screens
- Feature usage: Underuse of advanced filtering and prioritisation tools
Insight
The data showed that analysts were not lacking access to information, but were slowed down by the effort required to interpret and validate alerts. A large portion of time was spent understanding context rather than making decisions, reinforcing the issue of cognitive overload.
Journey Mapping
1. Signal vs Noise Problem
- Alerts are abundant but not prioritised effectively
- Analysts develop habits of ignoring alerts
Important threats risk being missed
2. Cognitive Overload
- Too much raw data, not enough structured insight
- Analysts must interpret everything manually
Mental fatigue and slower decisions
3. Lack of Explainability
- AI flags issues but doesn't justify them clearly
- Analysts don't trust or rely on automation
Underutilised AI systems
4. Fragmented Tooling
- Multiple systems → multiple interfaces
- No unified workflow
Time lost in navigation, not analysis
5. Slow Actionability
- Even after identifying a threat, response takes time
- Manual execution introduces delay
Increased impact of attacks
Security analyst workflow
Workshop: Co-Designing with SOC Analysts
Objective
To validate initial assumptions and uncover real-world challenges, we conducted a collaborative workshop with 15 SOC analysts from a range of experience levels.
The goal was to move beyond desk research and understand:
- How analysts actually work under pressure
- Where current tools fail them
- How AI could meaningfully support their workflow
Participants mapped their end-to-end threat response process, revealing consistent stages but a strong reliance on personal judgement rather than system guidance. Through collaborative discussions, key frustrations emerged, particularly alert overload, lack of context, fragmented tools, and low trust in AI-driven decisions.
A focused conversation on AI highlighted that analysts are not opposed to automation, but to systems that lack transparency. In response, participants co-designed ideal solutions, emphasising the need for explainable alerts, confidence scoring, unified data views, and faster, more intuitive response actions. This session reinforced that the core opportunity lies not in improving detection alone, but in supporting clearer, faster decision-making.
Key Insights from the Workshop:
1. Decision-making is the real bottleneck
Analysts don't struggle to detect threats, they struggle to decide what to do next.
2. Trust is built through transparency
AI systems are often ignored when they behave like a "black box."
3. Context is more valuable than volume
More data doesn't help, better-structured insight does.
4. Speed is critical, but clarity comes first
Analysts prefer slightly slower systems if they are more understandable and reliable.

04. Conceptualisation
The concept is guided by a set of core design principles aimed at improving how analysts interact with AI-driven systems. Information should be prioritised and simplified to reduce cognitive load, allowing analysts to quickly understand what matters and why. AI decisions must be transparent, providing clear explanations and supporting evidence to build trust.
Insights should be directly actionable, enabling faster transitions from detection to response. All relevant data and tools should be brought into a single, unified interface to minimise context switching, while maintaining a human-in-the-loop approach where automation supports, rather than replaces, analyst decision-making in high-risk scenarios. Most interfaces are often dense and require expert interpretation. Visualisations such as anomaly graphs and threat timelines provide deep insight but can increase cognitive load under pressure.
The solution is centred around four key components:
Intelligent Alert System
A prioritised alert feed that highlights high-risk threats and reduces noise.
AI Summaries
A dedicated space showing why an alert was triggered, including behavioural patterns and evidence.
Unified Threat View
A consolidated interface combining logs, user activity, and historical data in one place.
Rapid Response Actions
Predefined, easy-to-execute actions such as blocking IPs or isolating devices.
UI Exploration
Between sketching and vibe coding, I put together some concepts for how we could approach the UI.
Experimenting by placing all necessary information in cards in an organised manner.
As a user clicks on a card, they'll see an AI summary in the middle so as to not overwhelm them. Extra data points were removed, which analysts didn't like.
AI Search and Alert Summary Types
We explored search functionality that enables analysts to use natural language prompts to quickly surface relevant threats, behaviours, and assets without needing complex queries. Instead of relying on manual filters or technical syntax, analysts can ask questions such as "Show all high-risk alerts from the last 24 hours," "Find users with unusual login behaviour," or "Any activity linked to this IP address?" The system interprets intent, aggregates data across sources, and returns contextualised results, allowing analysts to investigate faster and with greater confidence.
I worked with the content team to explore alert types that users can become accustomed to based on the nature of the alert:
Proactive alerts
Alerts generated before a threat fully occurs, based on predictive patterns and risk signals.
Examples:
- "User behaviour deviating from normal patterns"
- "System showing early signs of compromise"
Prioritised alerts
Alerts automatically ranked and filtered based on risk, context, and potential impact.
Examples:
- Critical threats surfaced at the top
- Low-risk alerts grouped or deprioritised
Contextual alerts
Alerts enriched with relevant information and background context to support understanding.
Examples:
- Related user activity
- Historical behaviour comparisons
- Linked events or incidents
Actionable alerts
Alerts that directly suggest or enable next steps.
Examples:
- "Block IP"
- "Isolate device"
- "Escalate incident"
Adaptive alerts
Alerts that improve over time based on analyst behaviour and feedback.
Examples:
- System learns which alerts are ignored or acted on
- Adjusts prioritisation accordingly
05. Solution
In response to the challenges identified through research and workshop insights, the final solution is an AI-powered cybersecurity platform designed to support SOC analysts in making faster, clearer, and more confident decisions.
Rather than focusing solely on threat detection, the system reframes AI as a decision-support tool, helping analysts prioritise, understand, and respond to threats with reduced cognitive load.
The platform enhances the analyst workflow across four key stages:
- Monitor: Alerts are intelligently prioritised based on risk and relevance, reducing noise and highlighting critical threats
- Investigate: Each alert is enriched with contextual data and clear AI explanations, removing the need for manual data gathering
- Validate: Confidence scores and supporting evidence help analysts quickly assess the severity and legitimacy of threats
- Respond: Recommended actions and one-click responses enable rapid and effective incident management
The final concept transforms cybersecurity systems from passive monitoring tools into active decision-support platforms, empowering analysts to move from detection to action with greater speed, clarity, and confidence.
This solution aligns advanced AI capabilities with real human needs, ensuring technology supports rather than overwhelming those using it.
An efficient experience in which an analyst has a clearer view of what they need to prioritise and why.
This interface presents a centralised AI-powered cybersecurity dashboard that helps SOC analysts monitor and prioritise threats in real time. It combines high-level metrics, visual insights, and a detailed alert feed to support faster, more informed decision-making and response.
This interface allows analysts to quickly select an alert and view a detailed summary within the same screen, eliminating the need to navigate between multiple tools. By keeping investigation, context, and actions in one place, it enables faster exploration and more efficient decision-making through seamless interaction.
06. Reflection
This project reinforced the importance of designing AI systems around human decision-making rather than technical capability alone. While the technology behind threat detection is highly advanced, the real challenge lies in making that intelligence clear, trustworthy, and actionable for analysts working under pressure. Through research and collaboration, I learned that reducing cognitive load and improving transparency can have a greater impact than adding more features. Due to the legacy nature of some backend issues, this is an ongoing project but AI summaries alone have had a massive impact on analyst workflows:
"I don't have to dig through logs anymore: the summary tells me exactly what I need to know."
"Before, I'd spend minutes understanding an alert. Now I can make a call in seconds."
"I don't need to jump between tools anymore. Everything I need is already there."
