Welcome back to Radical Security Reviews. So far we've covered tools that find weaknesses (Tenable Nessus, Qualys VMDR) and tools that catch intruders (CrowdStrike Falcon). This time we turn to the layer every one of those tools depends on: people. KnowBe4 is the security awareness platform we see most often in client environments — and recommend most often.

Short version: it earned that spot. KnowBe4 pairs the largest training library in the category with a phishing simulation engine that actually changes click rates, wraps it in reporting that auditors and boards both understand, and prices it per seat so almost any organization can afford it. Below we cover setup, daily operation, content quality, reporting, compliance fit, pricing, and the handful of things worth knowing before you buy.

How we review products

The same ground rules apply to every review in this series. We don't resell anything — no vendor pays for placement, there are no affiliate links, and we have no commercial relationship with KnowBe4. We only review tools we've run in real environments on real engagements. And "positive" doesn't mean "uncritical": the edges are in the good to know section so you can buy with open eyes. You can find every review in our Product Reviews section.

What KnowBe4 is — and what it isn't

KnowBe4 is a cloud-delivered security awareness platform built around two engines that reinforce each other. The first is a training library — thousands of modules, videos, games and newsletters covering everything from phishing fundamentals to GDPR, including the well-known Kevin Mitnick security awareness content. The second is a phishing simulation engine that sends realistic fake phishing emails to your own staff, measures who clicks, and assigns remedial training automatically.

It comes in tiers — Silver, Gold, Platinum and Diamond — that scale the size of the content library, the sophistication of the phishing templates and extras like AI-driven training recommendations. Add-on products such as PhishER Plus extend into the SOC, triaging the phishing emails your users report.

Just as important is what KnowBe4 isn't. It isn't email security — it trains people to spot what the filters miss, rather than filtering mail itself. It isn't a phishing engagement by a red team, which tests people and process in ways a SaaS platform can't, as we explain in the difference between automated and manual testing. And it isn't a checkbox: the organizations that get value from it run it as a program, not an annual chore. The good news is the platform makes running that program remarkably easy.

Setup and first campaign

Setup is an afternoon, and most of it is user provisioning. KnowBe4 syncs users from Active Directory or your identity provider via SCIM, and its Smart Groups keep learners organized automatically as people join, move and leave — Finance gets finance-relevant content, new hires get onboarding training, and nobody maintains lists by hand.

The standard first move is a baseline phishing test: send everyone a simulated phish before any training, and measure your starting phish-prone percentage. That number is the foundation of the whole program — it's the "before" photo you'll compare against for years, and it's the figure leadership cares about. A typical first week: users synced on Monday, baseline phish sent Wednesday, first results and the first automatic remedial training by Friday.

Day-to-day use

Daily operation is where KnowBe4's maturity shows. The details that matter:

  • Campaigns that run themselves. Set a phishing cadence — monthly is common — pick a pool of templates, and the platform randomizes who gets what, when. You spend minutes per month, not hours.
  • Teachable moments, built in. A user who clicks a simulated phish lands on a page that shows exactly which red flags they missed, and remedial training is assigned automatically. The lesson arrives at the moment of maximum attention.
  • The Phish Alert Button. A one-click button in Outlook or Gmail lets users report suspicious email — turning your entire staff into a detection layer and feeding real phish to your IT team (or to PhishER Plus for automated triage).
  • Gamification that works. Badges, leaderboards and short-format content keep completion rates high without nagging from IT.
  • AI-driven assignments. On the higher tiers, training recommendations adapt to each user's behavior, so repeat clickers get more practice and careful users aren't bored by basics.

The practical effect is what we describe in Security Awareness Training That Actually Changes Behavior: short, frequent, blame-free touches beat an annual lecture every time — and KnowBe4 is purpose-built for exactly that cadence.

Training content and phishing quality

An awareness platform lives or dies on two things: whether employees finish the content, and whether the simulated phish look like real attacks. KnowBe4 does well on both.

The library is enormous and refreshed constantly — current scams, new regulations, role-specific tracks for developers, finance teams and executives, and multiple languages for distributed workforces. Content comes in lengths that respect people's calendars: two-minute modules get finished; hour-long courses don't. The phishing templates are modeled on lures in the wild — fake shipping notices, MFA fatigue prompts, QR-code scams, invoice fraud — and updated as real campaigns evolve, which keeps the simulation honest. Templates are customizable, so you can mirror the tone and branding of your own organization.

The result we see across client environments is consistent: baseline phish-prone rates commonly start in the double digits and drop to low single digits within a year of steady campaigning. That's the product working as advertised.

Reporting and metrics

Reporting is a standout. The headline metric — phish-prone percentage — trends over time per user, per department and per organization, with training completion tracked alongside it. Reports export cleanly for the three audiences that matter: managers who need a team view, auditors who need completion evidence, and executives who need one trend line. If you've ever assembled a board security report, you'll appreciate having a metric that fits on a single slide and moves in the right direction.

The underrated detail is industry benchmarking: KnowBe4 aggregates anonymized results across its customer base, so you can show leadership not just "we improved" but "we improved relative to peers our size in our industry."

Why compliance teams rely on KnowBe4

Awareness training is written into nearly every framework, and KnowBe4 produces the evidence to match:

  • PCI DSS v4.0. Requirement 12.6 mandates a formal security awareness program — training at hire, at least annually, with multiple communication methods — and Requirement 5.4.1 expects processes around phishing. KnowBe4 covers both, and completion reports are exactly the artifact a QSA asks for, as we note in Preparing for Your QSA Assessment.
  • HIPAA. The Security Rule's awareness and training standard (§164.308(a)(5)) expects ongoing training and security reminders — a natural fit for monthly modules and simulated phish.
  • Cyber insurance. "Do you conduct security awareness training and phishing simulations?" is now a standard underwriting question, as we detail in what cyber insurers now require. KnowBe4 lets you answer both with reports to prove it.
  • SOC 2 and ISO 27001. Both expect demonstrable awareness programs; enrollment, completion and campaign records satisfy the control with evidence to spare.

Good to know before you buy

An honest review includes the edges, so here they are — none of them dealbreakers, all of them useful to know:

  • It's a platform, not a program. Someone still needs to choose the cadence, pick templates and follow up with repeat clickers. Budget a few hours a month — or hand it to a managed service, which is exactly what our security awareness team does with it.
  • Features vary by tier. The biggest content library and AI-driven recommendations live in the upper tiers, so map the tier to your ambitions up front.
  • Templates reward a little tuning. The stock lures are good; lures that mirror your organization's real email style are better. Fifteen minutes of customization pays off in realism.
  • Culture beats tooling. The platform enables a blame-free reporting culture but can't create one by itself — leadership tone still matters, and KnowBe4's reporting gives leaders the numbers to talk about it constructively.

Pricing and licensing

The structure is simple: an annual per-seat subscription in four tiers (Silver, Gold, Platinum, Diamond), with per-seat pricing that drops as seat counts rise — so small organizations pay small-organization prices for the same platform enterprises use. Check KnowBe4 for current figures; the important point is the shape of the pricing, not the number. There is no infrastructure to run, content updates are included, and even the entry tier is a complete program rather than a crippled teaser.

The best starting point costs nothing: KnowBe4's free Phishing Security Test baselines your phish-prone percentage before you spend a dollar, which also gives you the number that justifies the purchase internally.

Who should buy KnowBe4

KnowBe4 is an easy recommendation for:

  • Organizations with compliance obligations — PCI DSS, HIPAA, SOC 2, ISO 27001 — that need training evidence auditors accept without discussion.
  • Teams that want to measure phishing risk, not just lecture about it: baseline, campaign, trend, report.
  • Distributed and hybrid workforces, where cloud delivery and short-format content reach people wherever they work.
  • Anyone facing an insurer's questionnaire that asks about awareness training and phishing simulations.

Who might start elsewhere? Organizations that want the entire program operated for them — campaign design, follow-ups, reporting — can pair the platform with a managed phishing simulation service and skip the internal hours entirely. But the platform underneath that service is very likely to be this one.

The verdict

Recommended. KnowBe4 has stayed the default choice in security awareness for the reasons that matter: a content library deep enough to keep training fresh for years, phishing simulations realistic enough to move real behavior, automation that keeps the program running on minutes a month, and reporting that satisfies auditors, insurers and boards from the same console. It turns the hardest part of security — the human layer — into something measurable, and measurable into improvable.

Paired with the scanners and EDR from our earlier reviews, it completes the picture: find the weaknesses, catch the intruders, and teach the people. And if you'd rather have the whole awareness program run for you — campaigns, follow-ups and board-ready reporting — that's exactly what our security awareness team does.

Frequently asked questions

Can KnowBe4 satisfy PCI DSS security awareness requirements?

Yes. KnowBe4 maps directly onto PCI DSS v4.0 Requirement 12.6, which mandates a formal security awareness program with training at hire and at least annually, and it supports the phishing-focused expectations of Requirement 5.4.1 with simulated phishing campaigns. Completion records and campaign reports double as assessor evidence, which is exactly what a QSA asks for.

What's the difference between KnowBe4 and hiring a managed security awareness service?

KnowBe4 is the platform: the content library, phishing engine and reporting. A managed service layers people on top — someone designs the campaigns, tunes the lures, follows up with repeat clickers and reports to leadership. Many organizations run KnowBe4 themselves with a few hours a month; others hand the platform to a partner and get the program fully operated. Either way, the platform underneath is the same.

Is KnowBe4 a good fit for a small organization?

Yes. Pricing is per seat in tiered bands, so small organizations pay small-organization prices, and the free Phishing Security Test lets you baseline your phish-prone percentage before spending anything. Setup is an afternoon, campaigns can run on autopilot, and even the entry tiers include a substantial training library.
