Cyber skill, proven on real systems.
ProofRange is our technical assessment platform. Instead of quizzes and resumes, candidates work in live, isolated environments, and an AI reviewer returns every attempt scored, summarized, and integrity-checked.

Integrity score from interaction signals. No webcam, no recording.
Real environments
Assessments that run on real systems.
Everything runs in the browser. Candidates never install software, and every attempt happens in an isolated environment that is torn down when they finish.
Cloud labs
Full cloud environments to build, attack, or defend, provisioned per candidate.
Terminal access
Real shells in the browser. No installs, no local setup, no excuses.
Remote desktop
RDP and VNC sessions for tooling that needs a full desktop.
Live web targets
Running applications to probe, exploit, or harden, isolated per attempt.

AI evaluation
An AI reviewer on every attempt.
The moment a candidate submits, AI reviews everything they did in the environment and writes the assessment a senior engineer would: a verdict, a summary, and the evidence behind both.
Evidence-grounded verdicts
Every claim in the review links back to what the candidate actually did in the lab, not to what their resume says.
One rubric for everyone
The AI applies the same criteria to every attempt, so scores stay comparable across candidates and across time.
Minutes, not days
Ranked results and written summaries arrive without pulling a senior engineer into every screen.
AI review · Candidate A
Strong pass“Compromised the target through SSRF against the metadata service, escalated with the stolen role, and reached the objective with a clear, methodical approach. Minor gap: skipped credential cleanup on exit.”
- Enumerated storage before pivoting (terminal, 12:04)
- Exploited SSRF to reach the metadata endpoint (web target, 12:19)
- Escalated privileges with the stolen role (cloud lab, 12:31)
- Skipped credential cleanup on exit (flagged for review)
Verdict delivered immediately after submission, with evidence for every claim.
Capabilities
Built for evidence, not vibes.
AI-powered evaluation
An AI-written, evidence-grounded review of every attempt, with a clear verdict. No manual grading queue, no rubric drift.
Integrity without webcams
A 0 to 100 integrity score built from interaction signals like paste counts, tab switches, and typing patterns. No recording, no camera access.
Flexible assessment building
Mix formats freely: questions only, hands-on only, or both. Tune difficulty, time limits, and Focus or Strict integrity modes per assessment.
Hiring and upskilling
Use the same environments to screen candidates or benchmark your existing team and track progress over time.
Why switch
Resume roulette vs. proof.
Manual technical screening burns senior engineers' time and still comes down to gut feeling. ProofRange replaces it with evidence.
Manual assessment
- Hours of senior engineer time per candidate
- Take-home tasks graded on the honor system
- Scoring that changes with the interviewer
- Webcam proctoring, or nothing at all
- Verdicts based on resume claims and gut feeling
With ProofRange
- AI-graded attempts with verdicts in minutes
- Live, isolated environments, nothing to set up
- The same rubric for every single candidate
- A 0-100 integrity score, no camera required
- Evidence-grounded reviews you can stand behind
Who it assesses
Assessment tracks cover the security roles teams actually hire for, from offense to defense to AI security. Select a role to see how hands-on challenges and targeted questions verify its skills.
