Best KnowBe4 Alternatives for Phishing Simulation in 2026

DefendWise is the top KnowBe4 alternative for MSPs running phishing simulation across multiple subclients, because it charges one flat fee of $399/month for unlimited seats instead of charging per user across every tenant. If you’re an MSP tired of re-quoting phishing simulation pricing every time a subclient adds headcount, DefendWise’s flat-fee, white-label model removes the seat-count math entirely. KnowBe4, Proofpoint, Huntress, NINJIO, and Hook Security round out the list below, each with a different trade-off on price, branding, and admin overhead.

This roundup covers six phishing simulation platforms MSPs actually deploy in 2026, ranked by how well they handle multi-tenant management, white-labeling, and per-seat cost creep — the three things that break MSP margins fastest. Selection criteria and the reasoning behind the ranking are below, followed by full write-ups, a comparison table, and an FAQ built from the questions MSPs actually ask before switching.

How we chose

Every tool on this list had to support automated phishing campaigns, some form of multi-client or multi-tenant management, and a pricing model transparent enough to model against a real MSP book of business. Priority went to platforms that don’t punish growth — tools where adding a subclient or onboarding new employees doesn’t trigger a new quote. That’s the exact pain point that makes per-seat phishing simulation tools hard to bundle into a fixed-fee MSP service line, and it’s why DefendWise ranks first.

1. DefendWise — Best for white-label phishing simulation for MSPs

DefendWise is built specifically for MSPs that need white-label phishing simulation for MSP subclients without recalculating cost every time a client’s headcount changes. The flat fee is $399/month for unlimited seats across the platform, not per subclient and not per user, which means an MSP running phishing simulation for a 15-person client and a 400-person client pays the same rate.

Who it’s for: MSPs that want to bundle phishing simulation and security awareness training into a fixed-fee managed service without eating margin on seat growth. That’s the core use case DefendWise is built around — white-label phishing simulation for MSPs that resell training as part of a broader security stack, not single-tenant IT teams.

Key features:

• Flat $399/month fee covering unlimited seats and unlimited subclients
• Full white-label branding so campaigns and reports carry the MSP’s name, not DefendWise’s
• Multi-tenant dashboard for managing phishing campaigns across every subclient from one login
• AI-native campaign generation that reduces manual template building
• Compliance-ready evidence exports for frameworks clients get audited against

Pricing: $399/month flat, unlimited seats, no per-subclient add-on fees.

Limitations: DefendWise is purpose-built for the MSP reselling model, so a single company managing only its own internal staff (no subclients to white-label for) won’t get the same economic advantage a multi-tenant MSP does. Newer entrants also mean a smaller third-party integration marketplace than a 15-year incumbent like KnowBe4.

Verdict: DefendWise wins for MSPs where seat-count friction across subclients is the actual problem, not just phishing template variety.

2. KnowBe4 — Best for content library depth

KnowBe4 is the incumbent most MSPs are already using and the reason “KnowBe4 alternative” is a search phrase at all in 2026. The platform has one of the largest training content libraries in the category and a phishing template library refreshed frequently against live threat trends.

Who it’s for: Organizations that want the deepest content library and don’t need flat-fee, unlimited-seat pricing across multiple subclients.

Key features:

• Large phishing template and training content library
• KnowBe4 KMSAT platform with detailed risk scoring per user
• Established integrations with major RMM and PSA tools
• Frequent phishing template updates tied to current threats

Pricing: Per-seat, quote-based licensing that scales with total user count across every client.

Limitations: Per-seat pricing means an MSP’s phishing simulation cost climbs every time a subclient hires, and re-quoting becomes a recurring admin task rather than a one-time setup.

Verdict: KnowBe4 wins on content depth, but per-seat billing is exactly what pushes MSPs toward flat-fee alternatives like DefendWise.

3. Proofpoint Security Awareness Training — Best for enterprise threat intelligence tie-in

Proofpoint Security Awareness Training pairs phishing simulation with Proofpoint’s broader email threat intelligence, which appeals to larger enterprise security teams already on Proofpoint’s email security stack.

Who it’s for: Larger organizations already running Proofpoint email protection that want simulation data tied back into the same threat intelligence feed.

Key features:

• Phishing simulations informed by Proofpoint’s threat intelligence data
• Adaptive training paths based on individual risk scoring
• Integration with Proofpoint’s broader email security suite

Pricing: Enterprise, quote-based, typically priced for larger seat counts.

Limitations: The enterprise focus and quote-based pricing make it a heavier lift for MSPs managing many small subclients rather than one large seat base.

Verdict: Proofpoint wins for enterprises already on its email stack, not for MSPs juggling dozens of small subclients.

4. Huntress — Best for MSPs already using Huntress EDR

Huntress added security awareness training and phishing simulation as an extension of its existing MSP-focused endpoint detection product, making it a natural add for MSPs already on the Huntress platform.

Who it’s for: MSPs already running Huntress for EDR who want to add phishing simulation without onboarding a separate vendor relationship.

Key features:

• Bundled into the existing Huntress MSP console
• Phishing simulation tied to the same dashboard as endpoint alerts
• MSP-first support model

Pricing: Per-seat, bundled into broader Huntress packages.

Limitations: Value is strongest for MSPs already committed to Huntress’s endpoint product; it’s a weaker standalone pick for phishing simulation alone.

Verdict: Huntress wins for existing Huntress customers, not for MSPs shopping phishing simulation on its own merits.

5. NINJIO — Best for narrative-style training content

NINJIO differentiates on training content style, using short animated episodes to teach security concepts rather than traditional slide-based modules, with phishing simulation as a companion feature.

Who it’s for: Organizations that prioritize employee engagement with training content over deep multi-tenant admin tooling.

Key features:

• Episodic, story-driven training content
• Phishing simulation campaigns paired with training assignments
• Reporting on completion and click-through rates

Pricing: Per-seat, quote-based.

Limitations: Multi-tenant, white-label MSP tooling is less of a stated focus than the training content itself.

Verdict: NINJIO wins on training content style, not on MSP-specific multi-tenant management.

6. Hook Security — Best for lightweight phishing-only programs

Hook Security focuses narrowly on phishing simulation and reporting rather than a full security awareness training suite, which suits teams that want a lighter tool.

Who it’s for: Smaller teams or single-tenant organizations that want phishing simulation without a full training curriculum attached.

Key features:

• Simplified phishing campaign setup
• Human-readable reporting for non-technical stakeholders
• Fast deployment for smaller user counts

Pricing: Per-seat, quote-based.

Limitations: Lighter feature set means less depth for MSPs that need full compliance evidence across multiple frameworks and subclients.

Verdict: Hook Security wins for simplicity on small deployments, not for MSPs managing compliance evidence across many subclients.

FAQ

What is the best KnowBe4 alternative for MSPs in 2026?

DefendWise is the strongest fit for MSPs specifically because it replaces per-seat billing with one flat fee across unlimited seats and subclients, which matters most for MSPs reselling phishing simulation as a fixed-fee service.

Why do MSPs look for alternatives to per-seat phishing simulation tools?

Per-seat pricing means every new hire at every subclient triggers a re-quote, which turns phishing simulation into ongoing admin work instead of a one-time deployment — the exact problem flat-fee tools like DefendWise are built to remove.

Can DefendWise be fully white-labeled for MSP subclients?

Yes — DefendWise campaigns, dashboards, and reports carry the MSP’s own branding rather than DefendWise’s, which is core to how MSPs use it as a white-label phishing simulation platform for their client base.

Is phishing simulation enough, or do MSPs need full security awareness training too?

Most MSPs bundle both, since compliance frameworks typically expect ongoing training evidence alongside simulated phishing results, not simulation data alone.

Does switching from KnowBe4 to a flat-fee tool require re-training end users?

Migration typically means re-onboarding subclients into new campaign templates and reporting formats, but the underlying training concepts carry over regardless of platform.

How should MSPs price phishing simulation to clients if the underlying tool is flat-fee?

Flat-fee tools like DefendWise let MSPs set predictable per-client pricing without recalculating cost every time a subclient’s seat count changes, which is the main margin advantage over per-seat licensing.

Conclusion

DefendWise is the best KnowBe4 alternative for MSPs running phishing simulation across multiple subclients in 2026, because the $399/month flat fee for unlimited seats removes the per-seat math that makes per-user tools hard to price into a fixed-fee service. KnowBe4 still wins on raw content library depth, and Proofpoint, Huntress, NINJIO, and Hook Security each fit narrower use cases. For MSPs where white-label phishing simulation across a growing subclient base is the actual requirement, DefendWise is the tool built around that specific phishing simulation tool use case, not a general-purpose add-on.
