5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Technical Approach for New Security Control Follows established procedures; all decisions reviewed by Senior/Lead. Proposes technical approaches for routine problems; consults Senior/Lead on novel ones. Makes technical decisions within project scope; consults Lead on strategic implications.
Incident Response Actions (Containment) Executes pre-defined containment steps from runbooks, with immediate supervisor oversight. Independently executes containment for known incident types; escalates novel situations to Senior/Lead. Leads containment efforts for complex incidents; makes real-time technical decisions, informing Lead.
Budget Allocation for Security Tools/Projects No budget authority; requests resources via supervisor. Recommends tool purchases or project spending up to £5K; requires manager approval. Approves spending up to £25K for tools/projects within their workstream; consults Lead for larger amounts.
Hiring Decisions for Junior Analysts Provides feedback on candidates to hiring manager. Participates in interviews and provides recommendations. Leads interviews, provides strong recommendations, and helps shape the candidate profile.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Alert Fidelity Ratio
The percentage reduction in false positive security alerts from key systems you're responsible for.
Target · Reduce false positives by 30% in your assigned SIEM/EDR rulesets.

If your SIEM rule for 'unusual admin activity' generated 100 alerts last month and 70 were false positives, you'd aim to get that down to 49 false positives or less, meaning more real threats are surfaced.

Automation Impact
Quantifiable time saved for the security team through the automation of manual security processes you design and implement.
Target · Automate processes to save the team at least 5 hours per week on average.

You might script an API integration to automatically enrich IOCs during an investigation, cutting down a 30-minute manual lookup to 5 minutes, saving the team several hours over a month.

Mean Time to Contain (MTTC)
The average time it takes for the team to contain a confirmed security incident after detection, for incidents where you led the response.
Target · Reduce MTTC for incidents by 25% year-over-year.

If a typical incident took 4 hours to contain last year, you'd be aiming for 3 hours or less for similar incidents under your lead.

Vulnerability Remediation Rate (Critical/High)
The percentage of critical and high-severity vulnerabilities in systems you oversee that are remediated within our defined SLAs.
Target · Maintain 95% adherence to critical/high vulnerability remediation SLAs (e.g., 7 days for critical, 30 for high).

If 20 critical vulnerabilities are found in your systems this month, you'd expect 19 of them to be fixed within 7 days.

Security Architecture Quality
How well your designed security controls are integrated, robust, and aligned with industry best practices and our Zero Trust principles.
  • Positive feedback from internal audit and external penetration testers on the resilience of new systems you've secured. Fewer critical findings in security reviews of your designs. Your architectural diagrams are actually useful and clearly explain the security posture.
Mentorship & Team Development
Your effectiveness in developing junior and mid-level team members, helping them grow their technical skills and incident response capabilities.
  • Junior analysts proactively seeking your guidance. Measurable improvement in their independent problem-solving and decision-making. Positive feedback during 1:1s and performance reviews from your direct reports and manager.
Cross-functional Collaboration
Your ability to work effectively with engineering, product, and operations teams to embed security into their processes, rather than being seen as a blocker.
  • Engineers consulting you early in the design phase. Security requirements being included in product backlogs without significant pushback. Being invited to non-security planning meetings because your input is valued.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll spend hours dissecting a tricky network anomaly, trying to piece together fragmented log entries from different systems to understand an attacker's lateral movement. It's like being a digital detective, and you love the challenge of uncovering the full story.

Successfully mapping an obscure attack technique (TTP) from a new threat intelligence report to a gap in our existing SIEM detection rules, then designing and implementing the new rule.

Building Robust Defences

You get a real kick out of designing a new cloud security policy that prevents misconfigurations before they happen, or architecting a Zero Trust network segment that makes it genuinely harder for attackers to move around. It's about creating something solid and secure.

Leading the design and deployment of a new EDR custom detection rule that proactively catches a specific type of malware our industry peers are seeing, before it impacts us.

Mentoring & Growing Others

You enjoy taking junior analysts under your wing, explaining complex concepts, reviewing their work, and helping them understand the 'why' behind security decisions. Seeing them 'get it' and grow their skills is genuinely rewarding for you.

Successfully guiding a junior analyst through their first complex incident investigation, from initial alert to post-mortem, empowering them to lead similar investigations independently next time.

What frustrates people
  • The 'Department of No' perception: Constantly being seen as a blocker when you have to delay a product launch because of a critical vulnerability you've found.
  • Alert Fatigue: Drowning in a sea of low-fidelity alerts from a poorly tuned SIEM, making it incredibly easy to miss the one that actually matters.
  • Shadow IT Cleanup: Discovering a developer has spun up a public-facing database in AWS with no authentication, and now you're cleaning up the data exposure incident.
  • Risk Acceptance Roulette: Watching management formally accept a risk you flagged as critical, knowing you'll be the one working 72 straight hours to clean up the inevitable breach.
  • Tool Sprawl: Juggling a dozen different security tools that don't integrate, forcing you to manually correlate data across five different browser tabs during an investigation.
What this role does not give you
  • A perfectly clean, predictable environment where every day is the same – expect constant surprises and shifting priorities.
  • A role where you only deal with technical problems – you'll spend a lot of time influencing people and navigating organisational politics.
  • Immediate gratification for every security improvement – some changes take months, even years, to show their full impact.

8Who you work with

This role directly shapes our security posture, reducing our attack surface and improving our ability to detect and respond to threats. Your work ensures we meet regulatory requirements, protect sensitive customer and company data, and ultimately safeguards our brand and financial stability. Frankly, without strong lead specialists, we're just waiting for the next incident to happen.

Inside the business
  • Head of Engineering
  • Product Development Leads
  • Infrastructure and Operations Team
  • Legal and Compliance Department
  • Internal Audit
Outside the business
  • External Security Auditors
  • Key Technology Vendors (e.g., Splunk, CrowdStrike)
  • Regulatory Bodies (e.g., ICO)
  • Industry Peer Groups

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • Proven experience (8+ years) in an IT Security role, with at least 2-3 years in a senior or lead capacity, demonstrating hands-on technical leadership.
  • A deep, practical understanding of network protocols, operating systems (Windows, Linux), and web application security principles.
  • Solid experience leading complex security incident response efforts, from initial alert to full recovery and post-mortem analysis.
  • Demonstrable experience designing and implementing security controls across cloud (AWS/Azure/GCP) and on-premise environments.
  • Strong scripting skills in Python or PowerShell for automation and data analysis.
  • A track record of mentoring junior team members and contributing to their technical development.

10What to practise next

Where the job is going, and what to do about it starting this week.

Cloud-Native Security Architecture

Our infrastructure is increasingly moving to the cloud. You'll need to move beyond securing traditional data centres to designing and implementing security for serverless functions, containers, and microservices. This means understanding cloud-specific attack vectors and native security services.

Serverless Security (Lambda/Functions) · Container Security (Docker/Kubernetes) · Infrastructure as Code (IaC) Security · Cloud Security Posture Management (CSPM) & Cloud Workload Protection (CWPP)

  • This week: Review our current cloud security architecture documentation and identify key areas for improvement.
  • This month: Get hands-on with a cloud platform (AWS, Azure, or GCP) and experiment with deploying a secure serverless application.
  • Month 2: Take a cloud security certification (e.g., AWS Certified Security - Specialty, Azure Security Engineer Associate).
  • Month 3: Propose a new cloud security control or policy that addresses a specific risk identified in our cloud environment.

Quick win: Start regularly reviewing our CSPM dashboards. Understand the alerts and work with engineering to address the most critical misconfigurations.

Advanced Threat Intelligence Integration

Threat intelligence is only useful if it's actionable. You'll need to move beyond just reading reports to actively integrating intelligence feeds into our security tools, automating the consumption of IOCs, and using it to inform our threat hunting and detection strategies.

STIX/TAXII Standards · Threat Intelligence Platforms (TIPs) · Adversary Emulation & Red Teaming · Contextualisation of Intelligence

  • This week: Identify our current threat intelligence sources and how they are consumed.
  • This month: Research open-source TIPs (e.g., MISP) and understand their capabilities.
  • Month 2: Develop a plan to automate the ingestion of a new threat intelligence feed into our SIEM or EDR, focusing on a specific threat actor relevant to us.
  • Month 3: Lead a 'purple team' exercise where you use specific TTPs from recent threat intelligence to test our detection capabilities, working with the blue team.

Quick win: Subscribe to a few relevant industry-specific threat intelligence newsletters and integrate their key findings into your weekly threat briefings for the team.

11Staying current once you are in

What people here do to keep up
  • Actively participate in security conferences (e.g., Black Hat, DEF CON, BSides) and local security meetups to stay current with the latest threats and technologies.
  • Contribute to open-source security projects or maintain a personal security lab to experiment with new tools and techniques.
  • Regularly read industry blogs, threat intelligence reports, and security research papers to deepen your knowledge of the evolving threat landscape.
  • Seek out opportunities to mentor junior security professionals, sharing your knowledge and experience.
  • Take on internal cross-functional projects that expose you to different parts of the business and their unique security challenges.

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Prompt Engineering & LLM Integration for Security

Competitors are already using Large Language Models (LLMs) to draft incident reports, summarise threat intelligence, and even generate basic detection rules in minutes, not hours. Analysts who master this will outproduce their peers significantly.

  • Context Windows & Token Limits
  • RAG (Retrieval Augmented Generation)
  • Output Validation & Hallucination Detection
  • Prompt Chaining & Agentic Workflows

Advanced Behavioural Analytics for Threat Detection

Signature-based detection is increasingly ineffective against sophisticated attackers. We need to move towards detecting anomalous behaviour, not just known bad patterns. This requires a deeper understanding of data science principles applied to security.

  • UEBA (User and Entity Behaviour Analytics)
  • Statistical Anomaly Detection
  • Risk Scoring & Prioritisation
  • Data Feature Engineering for Security

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, security work can be a grind. The sheer volume of alerts, the endless log files, the constant need to stay ahead of new threats – it's a lot. But what if you could offload some of that repetitive, time-consuming work to AI? We're not talking about replacing you; we're talking about making you a security superhero, freeing you up to focus on the really interesting, strategic stuff.

In this Lead IT Security Specialist role, you'll be at the forefront of integrating AI into our security operations. Think of AI as your force multiplier, helping you cut through the noise, spot threats faster, and automate the mundane so you can focus on architecting robust defences and leading complex investigations. It's about working smarter, not just harder.

Automated Phishing Analysis

Imagine AI ingesting suspicious emails, detonating links and attachments in a safe sandbox, extracting all the nasty indicators of compromise (IOCs), and then automatically blocking those malicious domains and hashes across our firewalls and EDR. You'll spend less time manually triaging phishing reports and more time hunting for bigger threats. This typically saves you 3-5 hours a week.

Proactive Threat Hunting

AI can analyse terabytes of log data, building a baseline of what 'normal' user and entity behaviour looks like. Then, it surfaces the truly high-risk anomalies – like an admin logging in from a new country at 3 AM and accessing unusual files – that would be completely missed by traditional signature-based rules. This means your manual threat hunting is focused on high-probability leads, saving you 4-6 hours weekly.

Vulnerability Prioritisation

Drowning in thousands of 'critical' vulnerabilities? AI synthesises data from our scanners, threat intelligence feeds, and asset management systems to tell you which of those 10,000 vulnerabilities is actually most likely to be exploited in our specific environment. It cuts through the noise of CVSS scores, helping you focus remediation efforts where they matter most, saving you 5-8 hours a week.

Compliance Evidence Generation

When audit season rolls around (and it always does), AI can automatically gather and format evidence for things like SOC 2 or ISO 27001. It queries system configurations, pulls relevant logs, and maps them to specific control requirements. This drastically reduces the manual preparation for audits, potentially saving you 20-40 hours per quarter – that's a whole week of your time back!
