About us
MI5 keeps the country safe from serious threats like terrorism and attempts by states to harm the UK, its people, and way of life. We carry out investigations by obtaining, analysing, and assessing intelligence, and then work with a range of partners including MI6 and GCHQ, to disrupt these threats. Through our protective security arm, we provide advice and guidance to government, businesses, and other organisations on how to keep themselves safe. A role in MI5 means you'll do unique and challenging work in a supportive and encouraging environment, making a real difference to UK national security.

The role
The UK faces growing threats to its cyber security. Staying ahead of rapidly evolving technological challenges and increasing demand from our partners is critical. That’s why our cyber team works at pace to analyse data and detect malicious activity that could harm national security. As a Cyber Threat Intelligence Analyst, you’ll support MI5’s cyber threat work and partner strategy. Drawing on your significant experience, you’ll identify, investigate, and analyse cyber threats, carrying out meaningful work that keeps the UK safe.

Work spans a range of technical areas, offering real scope. Day-to-day activities may include carrying out network analysis, applying an understanding of internet protocols to review network indicators, events, and topologies. Alternatively, disk and memory forensics knowledge may be applied to operating system artefacts, files and malware. Responsibilities may involve producing accurate reports or developing analytical or workflow capabilities, creating a diverse mix of investigative cyber work.

This role goes beyond supporting MI5’s operations, involving close collaboration with partners across government, finance, and the wider public sector to help meet growing demand. Activities range from performing intricate cyber analysis tasks and briefing internal and external stakeholders to using a variety of cyber tools. The role offers a good level of autonomy, while also encouraging you to support others by listening, guiding, and advising.

About you
You don’t need a specific degree to apply, but you’ll need significant experience working in cyber security, networking protocols, and data analysis, as well as either network- or host-based forensics. You’ll come from an applied cyber background, where you’ve gained experience in threat analysis, SOC analysis, threat intelligence, or similar. This may include experience in other government departments, law enforcement, or financial, regulatory, or legal institutions.

Our cyber team uses a wide range of tools and technologies, so expertise in any one is not essential. You might have had exposure to forensic tools such as X-Ways, FTK, and EnCase, or network and security analysis programmes including Elasticsearch, Splunk, and Wireshark. This will be supported by an awareness of coding and programming, allowing you to read and understand inputs.

Working as part of a busy yet collaborative team, you’ll be confident engaging with colleagues as well as external partners. With a well-developed analytical mindset, an organised approach, and a natural technical curiosity, you’ll think creatively to solve problems and seek to understand how and why incidents occur. There is an opportunity to turn findings into clear, well-structured reports, so good written communication skills and the ability to confidently explain complex technical subjects to non-technical audiences are essential. You’ll be keen to continue developing your technical capability, making the most of learning opportunities to stay ahead in a rapidly evolving cyber landscape.

Training and development
When you join, you’ll complete an organisation-wide Induction Roadmap and meet with key partners, customers, and stakeholders to build an understanding of how the team operates within MI5. Alongside this, you’ll take part in a departmental induction and team rotations, giving you the chance to learn by shadowing more experienced colleagues.

There are plenty of opportunities to support your training and development throughout your career with us. You’ll receive a yearly learning budget and personal learning days, as well as access to internal and external training courses, mentoring, and tailored support to help strengthen any gaps in your knowledge.

You’ll be encouraged to join the Cyber Technical Framework (CTF). This is how we assess the knowledge, skills, and attributes of our cyber technical specialists, while also providing support to help you to progress your career in ways that suit your ambitions. Membership of the CTF is based on an application process, supported by skills-based assessments.

Rewards and benefits
You’ll receive a starting salary of £53,267 plus other benefits, including:

25 days’ annual leave, rising automatically to 30 days after 5 years' service, plus an additional 10.5 days of public and privilege holidays
opportunities to be recognised through our employee performance scheme
an interest-free season ticket loan
an excellent pension scheme
a cycle to work scheme
facilities such as a gym, restaurant, and on-site coffee bars (at some locations)
paid parental and adoption leave

Equal opportunities
At MI5, diversity and inclusion are critical to our mission. To protect the UK, we need a truly diverse workforce that reflects the society we serve. This includes diversity in every sense of the word: people with different backgrounds, ages, ethnicities, gender identities, sexual orientations, ways of thinking, and those with disabilities or neurodivergent conditions. We therefore welcome and encourage applications from everyone, including those from groups that are underrepresented in our workforce, such as women, people from ethnic minority backgrounds, people with disabilities, and those from low socio-economic backgrounds.
