Companies Using KnowBe4

As of our March 2026 crawl, TechnologyChecker.io tracks 25,680 domains running KnowBe4 across 22,248 enriched company profiles. KnowBe4 holds 0.29% market share and ranks #8 in the Security Tools category, but that ranking is misleading -- we're measuring a human risk management SaaS platform against server-side security layers and CAPTCHA widgets. KnowBe4's real competitors (Cofense, Proofpoint Security Awareness, SANS Institute training) don't appear in our top 44 security tools by detection count, which makes KnowBe4 the dominant player in a niche that traditional web detection barely captures.

Growth Trajectory

KnowBe4 entered our detection data in September 2020 with 3,442 domains and grew 640% to reach 25,015 domains by December 2024. The steepest climb happened during 2021-2023, when organizations scrambled to address remote work security risks. Since mid-2024, growth has plateaued between 24,000 and 26,000 active domains, with 2025 showing minor fluctuations rather than continued expansion. This stabilization coincides with Microsoft bundling native security awareness tools into Office 365 licenses and the market uncertainty surrounding KnowBe4's $4.6B Vista Equity Partners acquisition. The plateau doesn't signal weakness -- it signals market maturity in early-adopter segments.

Sales Signal: Companies that adopted KnowBe4 during the 2021-2023 remote work surge are now approaching contract renewals. They've had 2-3 years of usage data and are evaluating ROI. Sales teams offering complementary security tools should target these renewal windows with value-add propositions.

"KnowBe4's 640% growth from 2020 to 2024 mirrors the broader shift from perimeter-based security to human risk management. Our data shows the organizations that adopted awareness training earliest are also the ones with the strongest email authentication stacks -- 98.35% SPF, 79% DMARC. They're not replacing firewalls with training; they're layering defenses." - Mehmet Suleyman, CEO at TechnologyChecker.io

Customer Profile

KnowBe4 serves two distinct markets. The first is micro-businesses checking the box for cyber insurance -- 36.8% have 1-10 employees, and 58.4% have fewer than 50. The second is enterprises running sophisticated human risk management programs -- our company list includes Cognizant, General Electric, Allianz, and Tesla. Financial Services (5.92%), Insurance (4.18%), and Construction (3.78%) lead industry adoption. The concentration in regulated or liability-exposed sectors makes sense: phishing attacks pose existential risks to banks and insurers. Construction's presence likely reflects cybersecurity insurance requirements driving training mandates rather than voluntary adoption.

Sales Signal: Financial services firms with 1-200 employees represent the highest-density KnowBe4 segment. These organizations face regulatory pressure and cyber insurance requirements that make security awareness training non-optional. They're strong prospects for adjacent compliance tools, penetration testing services, and incident response platforms.

Industry and Geographic Concentration

The United States accounts for 59.6% of customers, with the UK (6.8%) and Canada (5.5%) reinforcing Anglo-dominated adoption. Combined, English-speaking countries represent over 72% of the user base, reflecting both language-specific training content requirements and KnowBe4's US go-to-market focus out of Tampa, Florida. European presence is scattered across Germany (2.9%), Netherlands (1.8%), and Switzerland (1.6%). Limited penetration in non-English markets suggests localization gaps or strong regional competitors offering native-language security awareness content. The EU's NIS2 directive could change this dynamic -- expanding regulatory mandates for security awareness training may force European adoption regardless of language barriers.

Sales Signal: The 72% English-speaking concentration leaves European and Asian markets significantly underserved. Vendors offering multilingual security awareness training have a greenfield opportunity in Germany, Netherlands, and Switzerland, where KnowBe4's presence is minimal but regulatory pressure is mounting.

Migration Patterns

KnowBe4 gained 1,902 customers from Wordfence (a 45:1 gain ratio) and 618 from Imunify360 (a 12:1 ratio). Both sources are infrastructure-level security tools, not direct training competitors. This migration pattern tells a clear story: organizations that've already invested in basic security infrastructure eventually add KnowBe4 for the human layer. They're not replacing one platform with another; they're completing their security stack. Outbound churn is minimal -- only 81 customers switched to hCaptcha and 58 to Cloudflare Turnstile, both CAPTCHA services rather than training platforms.

Sales Signal: Companies that recently adopted Wordfence or Imunify360 are 6-12 months away from adding awareness training. Use TechnologyChecker.io to identify organizations with infrastructure security tools but no KnowBe4 detection -- they represent the next wave of human risk management buyers.

"The 45:1 gain ratio from Wordfence is the strongest inbound migration signal we've seen in the security category. It tells us KnowBe4 isn't competing with other training platforms -- it's capturing organizations that've already decided to invest in security and are now adding the human layer." - Mehmet Suleyman, CEO at TechnologyChecker.io

Technology Ecosystem

The tech stack data reveals near-total Microsoft alignment: 76.55% of KnowBe4 customers use Microsoft Exchange Online, with 73.97% on Office 365 Mail. This suggests KnowBe4 either integrates tightly with Microsoft security stacks or fills a gap for organizations wanting more sophisticated phishing simulation than Microsoft Defender offers natively. Security-conscious infrastructure choices reinforce this picture: 98.35% use SPF, 79.07% use DMARC, and 56.25% enforce HSTS. These organizations aren't gambling on security -- they're layering defenses across email authentication, DNS security, and transport layer protection.

Sales Signal: The 76.55% Microsoft Exchange overlap creates a precise targeting filter. Companies running Office 365 + Exchange without KnowBe4 are potential prospects, especially in financial services and insurance where compliance mandates training. Filter on TechnologyChecker.io for Microsoft stack + regulated industry to build high-conversion prospecting lists.

G2 Review Signals

Cross-referencing our crawl data with G2 reviews reveals alignment between adoption patterns and user sentiment. Automated training and full-featured platform (144 mentions) leads the positive signals, which tracks directly with the 58.4% sub-50-employee adoption we see -- these organizations need turnkey security awareness without dedicated IT security teams. User-friendly interface (139 mentions) reinforces the ease-of-deployment story. The top concern is phishing issues (37 mentions), where alert conflicts and limited proactive features create friction. Repetitive and simplistic modules (33 mentions) signal a content freshness gap that competitors could exploit. The 3.1:1 positive-to-negative mention ratio indicates strong overall satisfaction, but the phishing and repetitiveness concerns give sales teams concrete angles when positioning complementary or alternative solutions.

Key Takeaways

1. Dominant in a niche that's hard to detect. KnowBe4's 0.29% market share understates its position -- it's the web-detectable leader in human risk management, a category where direct competitors have minimal web footprints.

2. Microsoft alignment is both strength and risk. The 76.55% Exchange Online overlap creates deep integration value but also exposure if Microsoft expands native awareness training features.

3. Growth plateau signals market maturity. The 24,000-26,000 domain range since mid-2024 suggests early-adopter saturation, with NIS2 regulatory expansion as the most likely catalyst for the next growth phase.

4. Infrastructure security is the feeder funnel. The 45:1 gain ratio from Wordfence confirms organizations add KnowBe4 after investing in technical security, not instead of it.

5. AI-driven phishing will force adoption. KnowBe4's expansion into AI agent training (7 active AI agents as of January 2026) positions it for the next wave of social engineering threats.

Sales Applications

Outreach Template: "I noticed your organization uses KnowBe4 for security awareness training. Companies in [financial services/insurance/construction] that've been running phishing simulations for 2+ years typically need [advanced threat intelligence/incident response/compliance reporting]. We help KnowBe4 customers like [similar company] extend their human risk management beyond training modules."

Targeting Strategy: Filter TechnologyChecker.io for KnowBe4 customers by industry (Financial Services 5.92%, Insurance 4.18%), company size (51-200 employees for mid-market upsell), and tech stack (Microsoft Exchange Online 76.55% for Microsoft-aligned buyers). Prioritize US-based companies (59.6%) for highest density.

Competitive Angle: Position against KnowBe4's content repetitiveness concern (33 G2 mentions). For Microsoft-heavy organizations, pitch solutions that integrate natively with Defender and Azure AD. For companies approaching renewal after 2+ years, emphasize advanced analytics and ROI measurement that KnowBe4's basic reporting may lack.
