Hire security engineers with role-specific challenges
A resume says "Burp Suite, Nmap, Splunk." A hiring CTF shows whether the candidate can find the IDOR, triage the alert or write a report your client would accept. CTF7 runs role-mapped cybersecurity skills assessments with anti-cheat monitoring and per-candidate scorecards.

What is a hiring CTF?
A hiring CTF is a Capture The Flag competition built as a recruitment assessment. Candidates solve security challenges mapped to the role you are hiring for, and their results show which skills they have demonstrated. You shortlist on evidence of hands-on ability instead of keywords on a resume.
Our team sets up a hiring CTF with you as a private, invite-only round for your candidates. It runs on the Pro and Enterprise organization plans, whose included events cover the assessment round. If you would rather we also build the challenges or run the round, that is scoped and quoted with our team. For the background, read hiring security talent with CTFs.
Cybersecurity skills assessments mapped to the job
A SOC analyst and a pentester need different skills, so they should take different tests. Pick a track, adjust the difficulty for interns, freshers or experienced hires, and add your own stack-specific challenges.
Penetration tester / VAPT
Can they move from recon to impact on an unfamiliar target, and explain it in a report?
- Web exploitation: SQLi, auth bypass, SSRF, file upload
- Network and service enumeration, privilege escalation
- Active Directory attack paths for senior roles
- Raw Ops round: find, chain and report vulnerabilities, scored with CVSS 4.0
Application security engineer
Can they spot the bug in the code, prove it's exploitable and suggest a fix a developer will accept?
- Secure code review challenges with vulnerable snippets
- API security: broken object-level authorization, JWT flaws
- Business-logic bugs that scanners miss
- Remediation write-ups graded for clarity
SOC analyst (L1–L2)
Can they separate the real incident from the noise, and document it?
- Log analysis and alert triage questions with flags as answers
- Forensics: pcaps, memory and disk artifacts
- Phishing email and malware-behavior analysis
- Optional SOC simulation round with incident reports, run by our team and quoted separately
Cloud security engineer
Do they understand how cloud environments get breached?
- Misconfigured storage and over-permissive IAM policies
- Metadata-service and SSRF-to-credential chains
- Container and Kubernetes escape scenarios
- Custom scenarios built for your cloud stack by the challenge team
DevSecOps engineer
Can they find the leak in the pipeline before an attacker does?
- Secrets in repositories, images and CI logs
- Poisoned pipeline and dependency-confusion scenarios
- Dockerfile and infrastructure-as-code misconfigurations
- Hardening tasks judged on the fix, not just the find
Raw Ops rounds test report writing
Flags show that a candidate got the answer. They say nothing about whether the candidate can explain it to a client. In a Raw Ops round there are no flags. Candidates investigate a realistic target and submit vulnerability reports. Your reviewers triage them and accepted findings are scored with CVSS 4.0.
You see the skills a pentest or bug bounty role needs: scoping discipline, evidence, reproduction steps, impact reasoning and chaining low-severity bugs into a critical path.
Anti-cheat and proctoring signals
When a job depends on the result, some candidates will try to game it. CTF7 gives every candidate dynamic flags, so a flag copied from someone else points straight back to its owner. IP and browser tracking flags candidates sharing a machine or network, and full submission logs show the timeline behind every solve.
For high-stakes rounds, the Premium event plan adds advanced anti-cheat analytics and logs. Use them to review suspicious cases before an interview, not after an offer. How each signal works, in plain terms.
How hiring CTF anti-cheat works, in plain terms
CTF7 gives you four integrity signals, and each one answers a simple question. None of them is a verdict on its own. They tell your reviewers where to look before anyone is invited to interview.
Dynamic flags
"Whose answer is this?"
Every candidate gets their own version of each flag. If candidate A passes a flag to candidate B and B submits it, the platform knows the flag was issued to A, so both accounts show up for review. A flag posted in a group chat is useless to everyone else and points back to whoever leaked it. More in the dynamic flag glossary entry.
IP and browser tracking
"Is this two people, or one?"
CTF7 records the network and browser behind each session. When two candidate accounts share a machine or network, or one person plays more than one account, it shows. On a campus drive many students share one network, so read this signal alongside the others.
Alerts
"Do I need to look?"
Suspicious activity raises an alert for organizers. Review it alongside the live submission tracking in the admin panel, instead of reconstructing events from a spreadsheet a week later.
Submission logs
"How did they get there?"
Every submission is logged with a timestamp, right or wrong. A steady run of attempts looks different from five correct flags in two minutes after an hour of silence. The log also gives your interviewer something concrete to ask about.
| If a candidate tries to… | What CTF7 shows you | What your reviewer does |
|---|---|---|
| Submit a friend's flag | The flag was issued to another candidate | Review both accounts and their submission timelines |
| Sit with someone, or play two accounts | Shared IP or browser signals across accounts | Check whether the overlap is explained, such as a shared campus lab |
| Use answers leaked mid-round | Leaked flags don't work for anyone else and trace to their owner | Review the original owner, who shared the flag in the first place |
| Rush through solves they didn't do | Timestamped submission logs with an unusual pattern | Ask them to walk through those challenges in the interview |
| Get help off-screen | No platform can see a phone or a second person beside the laptop | Add a Raw Ops report round and interview on their own work |
Treat signals as questions, not convictions. A shared network or a fast solve has innocent explanations, and a wrongly rejected candidate tells their friends. Decide your review rule before the round: for example, "any alert means a second look at the logs, and a confirmed flag match means disqualification." Then apply it the same way to every candidate. Thinking about AI assistants as well? See should your CTF allow AI?
Which plan has what. Dynamic flags, IP and browser tracking, alerts and submission logs are part of the Standard plan and above. The Premium event plan adds advanced anti-cheat analytics and logs for high-stakes rounds. For the mechanics behind it, read dynamic flags and anti-cheat in CTFs.
From invite to interview in four stages
Assess on skill, then spend interview time only on people who have already shown they can do the work.
Talk to the event teamInvite candidates
Send the round link to your applicant list or campus cohort. Need more applicants than you have? Sourcing through open CTF7 events is what the hiring partner program is for.
Run the assessment
A time-boxed round on the role track you choose, with dynamic flags and anti-cheat on. Run it remotely or on-site during a campus drive.
Shortlist from scorecards
Each candidate's scorecard shows solves by category, time taken, Raw Ops findings and report quality, and any integrity alerts. Set a cut-off and build the shortlist from evidence.
Interview on their own work
Open the interview with "walk me through how you solved the JWT challenge." It is the fastest way to confirm the skill is real and to see how the candidate thinks.

| What you need | Hiring CTF on CTF7 | Resume screening | Take-home test |
|---|---|---|---|
| Measures hands-on skill | Directly, per category | Keywords and credentials only | Yes, for one task |
| Scales to hundreds of candidates | Automated scoring | Fast but shallow | Manual review per submission |
| Integrity controls | Dynamic flags, IP/browser tracking, logs | Hard to verify claims | Hard to tell who did the work |
| Tests report writing | Raw Ops rounds, CVSS 4.0 | No | Sometimes |
| Comparable results across candidates | Same challenges, same scoring | Subjective | Reviewer-dependent |
| Candidate experience | Engaging and time-boxed | Often no feedback | Can eat whole weekends |
| Doubles as employer branding | Open CTFs build reach | No | No |
