9 Best Cybersecurity Skills Assessment Platforms for Hiring

A few years ago I sat a Cyber Skyline assessment for a SOC analyst role at CrowdStrike. The product was functional. The UI was dated, the branding looked like a side project, but the core idea was right - stop pretending you can hire cyber security people from a CV alone.

A couple of years later I ended up on the other side of the table, sitting through a sales demo of the same platform for a SOC team I was building. The founder was pleasant, the product was the same. I could not build my own challenges, and there was no AI to help me author them. Today the company no longer offers a hiring product at all.

That experience is what this post is about. Hiring based on paper applications is CV astrology - it might be real, or it might be complete fiction, and you cannot tell from the document. Skills assessment platforms exist to give you something better. Here are the nine that come up most often, and an honest read on which one fits which problem.

The short version

If you are hiring cyber security people, the platform that fits your problem depends almost entirely on whether the underlying problem is hiring or training. HackerRank, Hack The Box, Immersive Labs and TryHackMe are world-class at parts of the wider cyber market, but none of them are built around the hiring decision. TestGorilla sits closer to the hiring brief but is a generalist, and Cyber Skyline, once a cyber hiring option, no longer offers a hiring product. TrueAbility runs hands-on, performance-based exams but is assessment infrastructure you build on, and Cloud Range is a cyber range whose hiring product measures aptitude rather than skill. CyberHire is the only one of the nine built end-to-end for the cyber hiring use case - which is the bias you should expect from a comparison post we wrote.

How to evaluate a cybersecurity skills assessment platform for hiring

Before the platform list, the criteria. If your shortlist is being driven by brand recognition rather than fit, you are going to overpay and under-screen. Six things matter:

1. Built around the hiring decision. Not training, not CTFs, not workforce upskilling. Hiring is a different workflow with different telemetry, candidate experience and reporting needs.
2. Cyber-specific challenge library. Coding-test platforms with a cyber category bolted on do not assess SOC, IR, GRC or threat intel work properly.
3. Real environments. Live Linux shells, packet captures, SIEM query workspaces, Windows event logs, cloud configurations. MCQs alone do not separate strong candidates from confident ones.
4. Integrity controls that match the modern threat model. You cannot fully prevent a candidate using AI, so the defence is task design - answers that only exist inside the artefact in front of them - plus observable signals such as time away from the test, external paste, fullscreen exits and second screens. The 2018 proctoring playbook does not work any more.
5. Speed to first test. Once the platform is set up, a hiring manager should be able to get a role-specific assessment live in minutes, not wait six weeks for the vendor to build it.
6. Commercial shape. Are you buying seats for a year, or paying for the role you are actually hiring for? If you hire in bursts, the shape of the commitment matters more than the headline number.

Now the platforms.

1. CyberHire

A cyber-security-only assessment platform, built by someone who hired cyber people for years and got tired of CV theatre. 270+ hands-on challenges across Linux, packet analysis, SIEM and KQL, Windows event logs, phishing analysis, cloud (AWS, Azure, GCP), code review and incident response. Send the job spec and the CyberHire team builds a tailored assessment for you. Three integrity modes (Unmonitored, Standard, Proctor) covering time-away and tab-switch tracking, external paste detection, fullscreen enforcement, second-screen detection and optional webcam snapshots with candidate consent. Your team can change anything in the assessment, but never has to.

Best for: SOC, IR, cloud, GRC, blue team, threat intel and AppSec hires. The product makes one assumption - that you are hiring, not training.

Where we fall short: brand recognition. We launched into 2026 and most hiring managers have not heard of us yet. The product wins, the distribution catches up later. If you want a vendor with a household name in your procurement deck, see HackerRank.

How it is bought: per role or as an annual programme, not per seat. A role campaign covers one live role for 90 days with no recurring commitment; teams hiring continuously take a tailored ongoing hiring programme. Both are agreed with our team, who set up your workspace.

2. HackerRank

The household name in technical screening for software engineers. Bundled with most major ATSs (Greenhouse, Workday, Lever, SmartRecruiters), a deep library of algorithmic and language-specific coding problems, and several years of cyber assessment content layered on top.

Best for: hiring software engineers. If the role is software-shaped first and security-aware second (DevSecOps, security-focused application engineering), HackerRank can carry most of the screening load. The brand familiarity is a candidate-experience win.

Where it falls short: HackerRank’s DNA is coding interviews. The cyber assessment module is a bolt-on, not the spine. If the role is SOC, IR, threat intel or GRC first, you will be wedging a coding-test-shaped tool into a cyber-shaped problem. We wrote a longer head-to-head on exactly this.

3. Hack The Box for Business

Hack The Box is an icon. Their consumer CTF platform, training labs and red-team community are some of the best in the industry. Their enterprise tier - HTB for Business - layers hiring on top of training, talent search, CTF infrastructure, and dedicated AI ranges.

Best for: red team and offensive security hiring where the candidate is already active on the consumer HTB platform and you can use that public signal directly. Also strong if you want to bundle hiring with team training under one contract.

Where it falls short: HTB is fundamentally a cyber training company that also does hiring. Nine product surfaces in their navigation, hiring is one of them. If the problem is purely “screen this candidate,” a focused hiring tool fits the workflow better. We covered this in the CyberHire vs Hack The Box breakdown.

4. Immersive Labs

Enterprise cyber resilience. Continuous skills development, cyber drills, board-level reporting. Used by government, financial services and large enterprises that need defensible, regulator-facing evidence of team readiness.

Best for: upskilling existing teams, not hiring new ones. Cyber drills, DORA reporting, workforce-wide security training. If you walk into a board meeting needing a number on cyber resilience, Immersive Labs is built for that conversation.

Where it falls short: it is not a hiring product. If a Head of Talent Acquisition asks Immersive Labs to screen 200 SOC applicants this quarter, the workflow does not bend that way. The platform is workforce-shaped. The full split is in CyberHire vs Immersive Labs.

5. TryHackMe for Business

Cousin to Hack The Box. Strong gamified training, CTF rooms, structured learning paths and a business tier for teams. Slightly more accessible to early-career candidates than HTB, with a friendlier UI.

Best for: training internal teams, gamified upskilling, and lightweight evaluation of junior or self-taught candidates.

Where it falls short: same shape problem as HTB. Hiring is a feature, not the spine. The candidate signal is “did they finish the room” rather than “would they make a good hire” - those are different questions with different telemetry. The platform is built for the first one.

6. Cyber Skyline (no longer offers a hiring product)

One of the longer-running cyber-specific assessment platforms, once used for hiring by some large enterprises (CrowdStrike included, at one point) and the company behind the National Cyber League CTF in the US. The challenge content was genuinely good: forensics, networking, scripting and several adjacent cyber categories.

Status: the current product line is self-paced learning for individuals, the NCL competition environment and a Lab Kit for educators. There is no hiring or candidate assessment product on offer.

Where it fell short as a hiring tool: I sat one of their assessments as a candidate and later had a vendor demo. The content was strong; the rest was weak. Dated UI. No self-serve challenge authoring - the vendor controlled the content. No generative AI. The full story is in our Cyber Skyline review.

7. TestGorilla

A generalist skills assessment platform with a wide test library across hundreds of skills, including a cyber category. Clean UX, fast onboarding, designed for breadth rather than depth.

Best for: small-to-mid-sized buyers hiring across many roles who want one tool for everything from sales SDRs to junior IT admins.

Where it falls short: the cyber library is broad but shallow. It works for a generalist Cyber Awareness Officer or a junior IT-meets-cyber role; it does not work for “is this candidate actually a senior incident responder.” The tests skew MCQ-and-short-answer, which is the format LLMs eat for breakfast.

8. TrueAbility

Assessment infrastructure for performance-based exams. Candidates work in live, provisioned environments rather than answering multiple-choice questions, with automatic grading, remote proctoring, ID checks and session recording. Its customers are certification bodies, training providers and hiring teams, and several large technology vendors run certification exams on it.

Best for: organisations that want to build and run their own hands-on exams at scale, particularly certification-style exams for IT, cloud and platform skills.

Where it falls short: it is infrastructure first. You build and deliver the exams on it; we found no ready-made library of cyber hiring assessments for roles like SOC, IR or GRC. If you want to stand up a hiring assessment for one role this week, rather than run an exam programme, that is a lot of building.

9. Cloud Range

A cyber range. Live-fire attack simulations across IT, OT and cloud environments, team exercises for SOC analysts and incident responders, a large library of individual labs, and tabletop exercises. Used by enterprises, critical infrastructure, government, higher education and MSSPs.

Best for: training and readiness validation for existing security teams, especially where realistic team-based simulations or OT and ICS scenarios matter.

Where it falls short for hiring: its hiring product, RightTrak, is a battery of short aptitude tests that maps a candidate’s cognitive strengths to cyber role families. That can be useful for spotting potential in entry-level candidates and career changers. It does not show whether someone can already do the job, for example whether a senior incident responder can scope a real intrusion, because it measures aptitude rather than demonstrated skill.

How to choose between them

Three questions in this order.

Are you hiring or upskilling? If upskilling, you do not need a hiring product. Immersive Labs, Hack The Box, TryHackMe and Cloud Range are world-class at training. Use the right tool for the right job.

Is the role cyber-first or coding-first? If the role is software-shaped (DevSecOps, security-focused engineering), HackerRank or a generalist platform like TestGorilla can carry most of the load. If the role is SOC, IR, threat intel, GRC or malware analysis, the platform should have been built for cyber hiring from day one.

How fast do you need a custom challenge? If the answer is “this week,” you need a vendor with AI-assisted authoring behind it. If the answer is “next quarter, once our admin team has filed the request,” a slower vendor-managed content model is fine.

What to do next

The most honest thing a comparison post can do is admit which buyer it is not for. CyberHire is not for a CISO who needs DORA-compliant reporting on team training - that is Immersive Labs. We are not for a recruiting team that already runs every candidate through HackerRank because procurement signed it three years ago. We are for the cyber hiring manager who has burned a week of senior engineer time on a candidate that turned out to be CV astrology, and wants the next test to actually screen for the job.
