This is a remote role open to candidates based anywhere in the UK, offering the opportunity to work across a diverse range of client environments — from enterprise networks to public sector systems.


You’ll be responsible for delivering hands-on penetration testing engagements, identifying vulnerabilities through systematic and innovative testing, and translating technical findings into meaningful business insights. The role offers strong progression opportunities, access to industry-recognised training, and involvement in advanced security projects.


The organisation is a leading UK-based managed service provider, delivering a comprehensive range of end-to-end technology solutions across Connectivity, Cloud, Collaboration, and Cyber Security. All services are designed, implemented, and supported by in-house specialists using a privately owned, state-of-the-art national infrastructure.



What You’ll Be Doing:

  • Conduct end-to-end penetration testing across infrastructure, web applications, and internal networks
  • Lead or support security testing engagements and deliver concise, high-quality reports
  • Translate technical findings into clear business impact and actionable recommendations
  • Communicate effectively with both technical and non-technical stakeholders
  • Stay up to date with current vulnerabilities, exploits, and industry best practices
  • Contribute to internal development of tools, research, and process improvement initiatives



What We’re Looking For:

  • 1–2 years of hands-on experience in manual penetration testing (infrastructure and/or web applications)
  • Strong understanding of TCP/IP, networking concepts, and web application architecture
  • Familiarity with tools such as Burp Suite, Nmap, Metasploit, or similar
  • Excellent written and verbal communication skills, including report writing and client presentations
  • Eligibility for SC Clearance (active clearance is a plus)



Nice to Have:

  • Working towards or holding a CREST qualification (CRT, CCT, or equivalent)
  • Experience conducting security build reviews across common operating systems (e.g. Windows, Linux)
  • Scripting or programming experience (e.g. Python, PowerShell, or Bash)
  • Knowledge of MITRE ATT&CK, TTPs, and adversary simulation techniques
  • Awareness of broader threat environments and current industry trends



What You’ll Get:

  • Competitive salary (up to £60,000, depending on experience)
  • Hybrid or remote working flexibility within the UK
  • Funded training and certification support (CREST, OSCP, or similar)
  • Opportunities to progress into red teaming, advanced testing, and leadership roles

Supportive, collaborative environment with a strong focus on professional development

How Many Cyber Security Tools Do You Need to Know to Get a Cyber Security Job?

If you are trying to build or move forward in a cyber security career, it can feel like the list of tools you are expected to know never ends. One job advert asks for SIEM platforms, another mentions penetration testing tools, another lists cloud security, threat intelligence platforms, endpoint detection, scripting languages and compliance frameworks. Scroll LinkedIn and it gets worse. Everyone seems to “know” dozens of tools, certifications and platforms. Here is the reality most cyber security hiring managers agree on: they are not hiring you because you know every tool. They are hiring you because you understand risk, can think like an attacker and a defender, follow process, communicate clearly and make good decisions under pressure. Tools matter — but only when they support those outcomes. So how many cyber security tools do you actually need to know to get a job? For most job seekers, the answer is far fewer than you think. This article explains what employers really expect, which tools are essential, which are role-specific and how to focus your learning so you look credible, not overwhelmed.

The Skills Gap in Cyber Security Jobs: What Universities Aren’t Teaching

Cyber security has become one of the most critical disciplines in the modern economy. From protecting financial systems and healthcare data to securing national infrastructure, cloud platforms and supply chains, cyber security professionals now sit at the frontline of digital trust. Demand for cyber security talent in the UK has surged. Job vacancies remain high, salaries continue to rise, and organisations across every sector report difficulty hiring skilled professionals. Yet despite this demand, many graduates struggle to break into cyber security roles and employers consistently report that candidates are not job-ready. The problem is not intelligence, ambition or academic effort. It is a persistent and widening skills gap between university education and real-world cyber security work. This article explores that gap in depth: what universities teach well, what they routinely miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build sustainable careers in cyber security.
