How to write a cyber security resume
By Mubeen Jawed, founder of ResumeForDev · Updated
A cyber security resume should show the threats you detected, the risks you reduced and the systems you protected, with numbers where you have them: alerts triaged, mean time to respond, vulnerabilities remediated, audit findings closed. Name your tools (Splunk, CrowdStrike, Burp Suite, AWS Security Hub), list certifications like Security+ or OSCP with the year, and for entry-level roles lead with labs, CTFs and home-lab projects.
Key points
- Quantify detection and response: alerts, MTTR, incidents handled.
- Certifications matter more in security than most tech fields. List them clearly.
- Entry level: home labs, CTF rankings and write-ups count as experience.
- Don't disclose confidential incident details. Describe the type and scale instead.
Analyst, engineer or entry level
A SOC or cyber security analyst resume centres on detection and response: monitoring, triage, investigation and escalation. A security engineer resume centres on building controls: hardening, cloud security, IAM, automation. Application security roles need code and secure-SDLC work. Match the first two bullets of each job to the side the posting emphasises.
Before:Monitored security alerts and responded to incidents.
After:Triaged ~150 SIEM alerts a day in Splunk for a 4,000-employee company, cut false positives 40% by tuning 25 detection rules, and led response on 12 confirmed phishing incidents.
Security metrics for a resume
| Area | Example phrasing |
|---|---|
| Detection | tuned 25 detection rules, cutting false positives 40% |
| Response | reduced mean time to respond from 6 hours to 90 minutes |
| Vulnerabilities | remediated 300+ critical and high CVEs across 900 hosts |
| Compliance | closed all 14 findings for the SOC 2 Type II audit |
| Identity | rolled out MFA to 2,500 users with under 1% help-desk escalations |
| Training | ran phishing simulations that cut click rate from 18% to 5% |
Example cyber security bullets
- Built automated enrichment for phishing reports in Python and the SOAR platform, saving analysts about 10 minutes per ticket.
- Ran authenticated vulnerability scans with Nessus across 900 servers and drove patching with owners, clearing the critical backlog in 6 weeks.
- Hardened AWS accounts with SCPs, GuardDuty and Security Hub, bringing CIS benchmark compliance from 61% to 94%.
- Performed web application penetration tests with Burp Suite on 8 internal apps, finding 2 critical auth bypasses fixed before launch.
- Wrote incident response playbooks for ransomware and account takeover, used in 2 tabletop exercises with IT and legal.
Cyber security skills and certifications
- Detection and response: SIEM (Splunk, Microsoft Sentinel), EDR (CrowdStrike, Defender), SOAR, incident response
- Offensive and AppSec: Burp Suite, Nmap, Metasploit, OWASP Top 10, threat modeling
- Cloud and identity: AWS or Azure security, IAM, Okta, zero trust
- Frameworks: NIST CSF, MITRE ATT&CK, ISO 27001, SOC 2
- Scripting: Python, PowerShell, Bash
Give certifications their own section near the top for security roles, with the issuer and year: CompTIA Security+, CySA+, CISSP, OSCP, AWS Security Specialty. See how to list certifications on a resume.
Entry-level cyber security resume
Hiring managers know entry-level candidates don't have incident history. They look for evidence you practise: a home lab (a SIEM ingesting your own logs, an Active Directory lab you attacked and defended), CTF placements, TryHackMe or Hack The Box progress, and short write-ups on a blog or GitHub. Put these in a Projects section with the same bullet format as a job.
On ResumeForDev, set your target role to “Security Engineer”. Without a job post, the keyword check falls back to a general software vocabulary, so for this role it's worth pasting the job description. Paste a job description and the keyword check uses that post's terms instead; on Pro, the writer also tailors the bullets to it. Before writing, it asks follow-up questions about the numbers above, and it removes any number or skill you never gave it. Your first resume is free.
Frequently asked questions
- What should I put on an entry-level cyber security resume?
- Certifications (Security+ is the common first one), a home lab or two described as projects, CTF results, relevant coursework, and any IT or help-desk experience, with bullets about the security parts of that work.
- What skills are good for a cyber security resume?
- SIEM and EDR tools, incident response, vulnerability management, network fundamentals, cloud security, scripting in Python or PowerShell, and frameworks like NIST or MITRE ATT&CK. List only what you've used.
- Where do certifications go on a security resume?
- In their own section near the top, with the issuing body and year. Security hiring filters on certifications more than most tech fields.
- What are the best keywords for a cyber security resume?
- Use the job post's terms: commonly SIEM, incident response, threat detection, vulnerability assessment, SOC, IAM, cloud security, and the specific tools named.
