Cyber Security Analyst CV Examples & Writing Guide

A cyber security analyst CV gets an interview when the first screen shows the tools you have actually used (SIEM, EDR, vulnerability scanner, by name), the volume you handled (alerts per shift, incidents, assets), your certifications (Security+ at minimum, CySA+, GCIH or a CREST analyst exam for SOC roles), any security clearance, and one detection or response result with a number. Below: a full SOC analyst sample, personal statements, bullets, certifications and a no-experience version.

Every tool is named with the vendor's spelling and every bullet has a volume (alerts, endpoints, incidents) or a change (MTTR, false positives, click rate). A CV that says "monitored security tools" without names or numbers goes in the second pile.

What a SOC manager checks in the first 30 seconds

Security analyst adverts get hundreds of applicants, many of them career changers with a certificate and no hands-on time. SOC managers look for four things to separate people who have done the job from people who have read about it.

  • Named tools with evidence of use. Not "SIEM" but "Splunk Enterprise Security" or "Microsoft Sentinel (KQL)"; not "EDR" but "CrowdStrike Falcon". Then a bullet that shows you used it: alerts triaged, searches written, hosts isolated.
  • Incident handling you can tell as a story. One or two real incidents (phishing that led to a mailbox rule, malware on a workstation, a compromised service account) with what you found, what you did and how long it took. Interviewers will ask; the CV should promise the story.
  • Certifications and clearance that match the level. Security+ is the floor for most analyst roles. CySA+, GCIH, GCIA, SC-200, Cisco CyberOps Associate or a CREST intrusion analyst exam show SOC depth. For government, defence and many MSSP roles, active SC clearance (or eligibility for it) matters too. CISSP on an entry-level CV raises eyebrows unless you have the 5 years it requires.
  • Fundamentals. Networking (TCP/IP, DNS, how a packet moves), Windows and Linux logs, Active Directory basics and some scripting. Managers test these in the interview, so a CV that shows them (service desk, systems administration, home lab, a networking cert) gets the call.

“Show me the SIEM you used, how many alerts you cleared on a bad day, and one incident you owned end to end. Candidates who list twelve frameworks and no incidents have usually never sat a shift.”

Personal statement examples for a cyber security analyst CV

Three to four lines under the header. Level and years first, then environment (SOC, in-house, MSSP), then tools, then one result and your certifications.

SOC analyst (tier 1, 1–2 years)
SOC analyst with 18 months on a 24/7 shift rotation at a managed security provider, triaging 100+ alerts a shift in Splunk and SentinelOne for 40 clients. Escalation accuracy of 94% in monthly quality reviews; wrote 8 correlation searches adopted across the client base. CompTIA Security+ and CySA+, SC cleared.
Experienced cyber security analyst (in-house)
Cyber security analyst with 5 years protecting a 6,000-employee manufacturer: Microsoft Sentinel, Defender for Endpoint and Tenable across 8 plants. Led response on 60+ incidents including two ransomware attempts stopped before encryption, kept the group's Cyber Essentials Plus certification, and cut critical vulnerabilities over 30 days old by 78%. GCIH, SC-200, Security+.
Entry level, from IT service desk
Service desk analyst with 3 years supporting 1,200 users in Active Directory and Microsoft 365, now moving into security operations. Handled first response on 400+ reported phishing emails, rolled out MFA to 1,200 accounts, and run a home SOC lab (Wazuh, Security Onion, Sysmon) documented on GitHub. CompTIA Security+ (2026), CySA+ booked for November 2026.
Entry level, new graduate

Built a detection lab with Splunk and Sysmon and wrote 15 ATT&CK-mapped detections. CompTIA Security+ and ISC2 CC.

Career objective or personal statement? Use a personal statement in every case. Even with no paid experience, the graduate example above says what you have done (placement, labs, detections written) rather than what you hope for.

Cyber security analyst experience bullets: weak to strong

Each bullet needs the tool, the volume and the outcome. Six lines that appear on hundreds of analyst CVs, rewritten with the detail a SOC manager wants. Change the figures to yours.

WeakStrong
Monitored SIEM for security events.Triaged 90 to 130 alerts a shift in Splunk Enterprise Security across 7,000 endpoints, closing 85% as tier 1 and escalating true positives with full timeline and IOC list.
Responded to security incidents.Led containment on 35 confirmed incidents in 2025 (BEC, infostealer malware, exposed credentials), isolating hosts in CrowdStrike within 15 minutes of confirmation and writing the post-incident report for each.
Analysed phishing emails.Analysed 250+ user-reported phishing emails a month, pulled 40 malicious messages from 1,100 mailboxes with Microsoft Purview, and added 60 sender and URL blocks to Proofpoint.
Performed vulnerability scans.Ran weekly Tenable scans on 3,200 servers and workstations, prioritised by exploitability using CISA KEV, and drove the count of critical findings open over 30 days from 180 to 22.
Created detection rules.Wrote 28 KQL analytics rules in Microsoft Sentinel mapped to MITRE ATT&CK (credential access, lateral movement), which surfaced 6 confirmed incidents that existing vendor rules had missed.
Reduced false positives.Tuned 14 noisy alert rules over one quarter, cutting daily alert volume by 41% (from 610 to 360) with zero missed true positives in the following six months of reviews.

Cyber security analyst skills for your CV (tools, frameworks, fundamentals)

Group the skills section by category and keep it to 12 to 16 entries. Recruiters search applicant tracking systems for tool names, so spell them the vendor's way. List only what you have touched.

  • SIEM and log platforms: Splunk Enterprise Security, Microsoft Sentinel, IBM QRadar, Elastic Security, Google SecOps (Chronicle), Sumo Logic, Wazuh (open source)
  • Endpoint detection and response: CrowdStrike Falcon, SentinelOne, Microsoft Defender for Endpoint, Carbon Black, Palo Alto Cortex XDR
  • Vulnerability management: Tenable Nessus and Tenable.io, Qualys, Rapid7 InsightVM, CISA KEV prioritisation
  • Network and perimeter: Palo Alto, Fortinet, Cisco ASA, Zscaler, Wireshark, Zeek, Suricata, Snort
  • Email and identity security: Proofpoint, Mimecast, Microsoft Defender for Office 365, Okta, Entra ID (formerly Azure AD), MFA and conditional access
  • Automation and scripting: Python, PowerShell, Bash, KQL, SPL, regular expressions, Splunk SOAR, Palo Alto Cortex XSOAR, Tines
  • Threat intelligence and analysis: MITRE ATT&CK, VirusTotal, AbuseIPDB, MISP, Shodan, basic malware triage in a sandbox (Any.Run, Joe Sandbox)
  • Frameworks and regulations: NIST CSF 2.0, NIST SP 800-61, CIS Controls, ISO/IEC 27001, NCSC Cyber Assessment Framework, Cyber Essentials and Cyber Essentials Plus, PCI DSS, UK GDPR breach handling (72-hour reporting to the ICO), NIS Regulations and NHS DSPT if you have worked under them
  • Fundamentals: TCP/IP and DNS, Windows Event Logs and Sysmon, Linux auth and syslog, Active Directory, cloud logging (AWS CloudTrail, Azure Activity Log, GCP audit logs)

Soft skills matter in a SOC but do not list them as words. Show them: "wrote incident reports read by the CISO", "trained 4 new tier 1 analysts". Clear writing under time pressure is the skill managers complain about most.

Certifications on a cyber security analyst CV: required, useful, and how to list them

No licence is required to work as a cyber security analyst in the UK, so certifications are how employers check your baseline. The UK Cyber Security Council's professional titles (Associate, Principal, Chartered) are growing but not yet expected at analyst level. List certifications in a separate Certifications section with the year, most recent first, and add the ones you are studying for with the booked exam date.

  • CompTIA Security+: the baseline. Most analyst adverts list it as required or preferred, including many MSSP, public sector and defence supplier roles. If you have nothing else, get this.
  • CompTIA CySA+ and CREST analyst exams: CySA+ is the SOC-specific step up (log analysis, threat detection, incident response). CREST's intrusion analyst exams (Practitioner, then Registered) are well known among UK MSSPs and CREST member companies.
  • GIAC GCIH (incident handling), GCIA (intrusion analysis), GSEC (fundamentals): expensive, employer-funded in most cases, and strongly respected by SOC managers.
  • Microsoft SC-200 (Security Operations Analyst): valuable where the stack is Sentinel and Defender, which covers much of the UK public sector, including the NHS, and many large companies. Splunk Core Certified User or Power User does the same for Splunk shops.
  • ISC2 Certified in Cybersecurity (CC): an entry-level certificate and a reasonable first line for students. ISC2 closed new sign-ups for its free exam offer in May 2026, so budget for the exam fee and the annual maintenance fee. ISC2 SSCP sits one step above.
  • CISSP: requires 5 years of paid experience (4 with a relevant degree). Do not list it as "in progress" on an entry-level CV. If you passed the exam without the experience, you are an "Associate of ISC2", and that is the correct wording.
  • Security clearance: if you hold active or recently lapsed UK clearance (BPSS, SC, DV), put it in the header line. You cannot apply for clearance yourself; an employer sponsors it, which is why "SC cleared" is one of the most searched terms for government and defence supplier roles.

Cyber security analyst CV with no experience (entry level, graduate, career change)

"No experience" in security rarely means no relevant experience. Service desk, systems administration, networking and Armed Forces communications roles all contain security work if you pull it out. What you cannot skip is hands-on evidence: a SOC manager needs to see that you have looked at logs and alerts, even in a lab.

  1. 1Certifications and education at the top: Security+ (or the exam date), ISC2 CC, any networking cert (CompTIA Network+, CCNA), your degree, apprenticeship or Skills Bootcamp. Add relevant modules only if you have no certifications yet.
  2. 2A Projects or Home Lab section written like a job, with numbers: "Built a SOC lab on Proxmox with Wazuh SIEM, Sysmon on 3 Windows VMs and Suricata; wrote 20 detection rules mapped to MITRE ATT&CK and documented 6 simulated attacks on GitHub." Link the GitHub repository in your header.
  3. 3Platforms and hours, honestly: TryHackMe SOC Level 1 path completed, LetsDefend 40 alerts investigated, Blue Team Labs Online, HackTheBox Sherlocks, CyberDefenders challenges, a university CTF placement. Managers know these names and the effort each represents.
  4. 4Your current or past job, with the security parts pulled forward: phishing tickets handled, MFA or patch rollouts, AD account audits, firewall change requests, incident write-ups, anything with logs.
  5. 5Placements, apprenticeships and volunteer work: a 3-month SOC placement is worth more than any certificate; put it under Experience with alert counts. Volunteer security work for a charity (MFA rollout, a phishing test, Cyber Essentials preparation) counts too.
Home lab bullet
Built and maintain a detection lab (Splunk free tier, Sysmon, Atomic Red Team on 2 Windows VMs, pfSense); ran 40 ATT&CK techniques, wrote 18 detections and published the walkthroughs on GitHub (300+ stars).
Service desk bullet rewritten for security
First responder for 30 to 50 user-reported phishing emails a month: checked headers and URLs, pulled 9 confirmed malicious messages from mailboxes with the security team, and reset 25 compromised accounts.
Placement bullet
SOC placement student (summer 2026): triaged 25 to 40 alerts a day in Microsoft Sentinel under a tier 2 mentor, wrote 12 incident tickets that were escalated as true positives, and tuned 3 noisy rules that cut daily alert volume by 15%.
Do not list a tool you have only watched a video about. SOC interviews include a practical: "here is an alert, walk me through it". Labs count as hands-on; tutorials do not.

Format, length and ATS keywords for a cyber security analyst CV

  • Length: two pages for most analysts; one page is enough at entry level. Senior analysts, incident responders and anyone with a long list of engagements or a clearance history use two full pages.
  • Order for experienced analysts: header (with clearance if any), personal statement, experience, skills grouped by category, certifications, education. Entry level: header, personal statement, certifications, projects or lab, experience, education.
  • Layout: single column, plain headings, standard fonts. Large companies, MSSPs and government suppliers use applicant tracking systems that read text only. A dark technical template such as cvplex cyber-security is fine as long as it stays single column and text-based. No photo and no date of birth on a UK CV; state your right to work and clearance level instead if relevant.
  • Mirror the advert's exact tool and framework names when they are true for you: SIEM, EDR, incident response, threat hunting, vulnerability management, MITRE ATT&CK, NIST, ISO 27001, Cyber Essentials, NCSC CAF, UK GDPR, PCI DSS, Splunk, Sentinel, CrowdStrike, KQL, Python. The ATS matches strings, not synonyms.

Frequently asked questions

How do I write a cyber security analyst CV?

Open with a 3 to 4 line personal statement giving your level, environment (SOC, in-house, MSSP), main tools and certifications, and one result with a number. Then give each job 3 to 5 bullets that name the tool, the volume (alerts, endpoints, incidents) and the outcome (MTTR, false positives cut, vulnerabilities closed). Group skills by category and list certifications with years. Two pages at most; one at entry level.

What skills should I put on a cyber security analyst CV?

The specific SIEM and EDR you used (Splunk, Sentinel, CrowdStrike, Defender), vulnerability scanners (Tenable, Qualys), incident response and phishing analysis, scripting (Python, PowerShell, KQL), MITRE ATT&CK, the frameworks and regulations you have worked under (NIST, ISO 27001, Cyber Essentials, NCSC CAF, UK GDPR, PCI DSS) and fundamentals such as TCP/IP, Windows and Linux logs and Active Directory. Only list what you can talk through in an interview.

How do I write a cyber security analyst CV with no experience?

Put certifications first (Security+ at minimum, ISC2 CC if you have it), then a Projects or Home Lab section written with numbers (detections written, attacks simulated, labs completed on TryHackMe or LetsDefend), then any IT job with its security tasks pulled forward (phishing tickets, MFA rollout, account audits). Link a GitHub with your lab notes. Keep it to one page.

Which certification is most important for a cyber security analyst CV?

CompTIA Security+ is the baseline most adverts ask for. For SOC roles, CySA+, GIAC GCIH, Microsoft SC-200 or a CREST intrusion analyst exam add the most. CISSP is for people with 5 years of experience and should not appear on an entry-level CV as anything other than a future plan. For government work, SC clearance often matters as much as any certificate.

What is a good personal statement for a cyber security analyst?

Three lines: level and years, environment and tools, a result with a number, and certifications. Example: "SOC analyst with 2 years on a 24/7 rotation triaging 100+ alerts a shift in Splunk and SentinelOne; 94% escalation accuracy; Security+ and CySA+; SC cleared." Use a personal statement, not a career objective, even at entry level.

How is a SOC analyst CV different from an information security analyst CV?

A SOC analyst CV is about detection and response: alerts per shift, incidents handled, SIEM and EDR tools, shift work. An information security analyst CV is often broader and includes governance, risk and compliance: access reviews, supplier assessments, ISO 27001 audit evidence, Cyber Essentials, policy work. Read the advert and lead with the side it emphasises.
