Cyber skill, proven on real systems.
Put candidates and teams into real environments: cloud labs, terminals, remote desktops, and live web targets, plus question sets for the theory. AI scores the work and an integrity check runs in the background. Built for hiring, and for growing the team you already have.
Integrity
AI evaluation
Claims are easy. The work is the test.
A resume tells you what someone says they can do. A quiz tells you what they remember. Neither shows whether they can sit down at a real system and get the job done. ProofRange measures both. Ask questions for the knowledge, and put candidates in a live environment for everything a question cannot show.
Give them a real system, not a screenshot.
Each hands-on challenge runs in its own isolated environment that the candidate actually operates, right in the browser with nothing to install. When the job is done, they capture a flag to prove it.
Cloud labs
Full cloud environments to build, attack, or defend.
Terminal access
A real shell on the box. Recon, exploit, escalate.
Remote desktop
RDP and VNC in the browser. No client, no setup.
Live web targets
Real, vulnerable web apps to probe and break.
AI reads every attempt, so your team does not have to.
Open answers and hands-on sessions are summarized and scored automatically. Every candidate is measured against the same bar, and a review that used to take an evening takes a few minutes. You stay in charge: the AI points out what matters, and you make the call.
Chained a path traversal into remote code execution on the Apache target, then moved to the database with reused credentials. Clear method, little wasted effort, each step written up. Two challenges solved in full, one partial.
Integrity is built in. No webcam needed.
Every assessment gets a score from 0 to 100, built from real interaction data: how much was pasted, how often the tab lost focus, idle time followed by sudden bursts, and typing rhythm. AI flags sit on top. A flag asks a person to take a closer look. It never rejects anyone on its own.
Two modes, set per assessment
Use Focus for a calm candidate experience, or switch any assessment to Strict when more is on the line. Either way, you can see the exact reasons behind every score.
Build the assessment that fits the role.
Pick from a library of hands-on challenges and question banks, or write your own. Run it as questions only, hands-on only, or a mix of both. Set the time limit, the difficulty, and the integrity mode for each one, then invite candidates one at a time or in bulk.
Rank people on what they actually did.
Scores, time, and integrity in one sortable table. Sort by integrity to send your review time straight to the attempts that need a second look.
Hire from outside. Grow from within.
Hiring
Test candidates on real skill before or after the interview. Choose the format that fits the role: questions only, hands-on only, or both. Walk into the hiring panel with evidence instead of opinions.
Upskilling
Benchmark your own team, find the gaps, and track progress over time. Turn a rough sense of where the team needs work into a plan you can measure.
From job spec to decision in five steps.
Build
Pick challenges and questions, set the mode and integrity.
Invite
Add candidates one by one or in bulk.
They work
Candidates work in a real, isolated environment.
AI scores
The work is summarized, scored, and integrity checked.
You decide
Rank, compare, and choose with evidence.
The typical way vs ProofRange
You have seen the real environments. Here is how everything else compares, from the first click a candidate makes to what you pay.
The typical way
--- a/typical-approach
ProofRange
+++ b/proofrange
The typical wayInstall a lockdown app, grant webcam, microphone and screen recording, photograph an ID, wait for review.
ProofRangeOpen a link in the browser. Nothing to install. No camera, no microphone, no ID.
The typical wayWebcam snapshots, screen recording and face matching, stored and reviewed after the test.
ProofRangeA 0 to 100 integrity score from interaction signals. No webcam, no recording, ever.
The typical wayRaw scores, percentiles and pass or fail thresholds, left for you to interpret.
ProofRangeAn AI-written, evidence-grounded review of every attempt, with a clear verdict. You decide.
The typical wayRecruiter seats, expiring attempt quotas, overage fees, auto-renewing contracts.
ProofRangeSimple credits, spent only when a candidate actually starts. Inviting is free. Top-ups last 12 months.
Category comparison, made in good faith. The typical way describes common practice across mainstream assessment platforms. No specific vendor is implied.

Questions, answered.
How are credits counted?
Is this proctoring?
Can candidates cheat with AI assistants?
Do candidates need to install anything?
Can I run questions instead of hands-on?
Can I use it for my own team?
What data do you collect about candidates?
How does the AI evaluation work?
Is it only for cybersecurity roles?
