What is the best phishing simulation tool in 2026?

There is no single best tool — it depends on who you are. KnowBe4 offers the broadest content library, Hoxhunt focuses on adaptive gamified training, and GoPhish is the leading free open-source option for technical teams. Trainers and platforms that want to deliver simulations under their own brand are better served by white-label, API-first infrastructure like Pavlov.

What are the best GoPhish alternatives?

Common GoPhish alternatives include managed SaaS platforms like KnowBe4, Hoxhunt, Proofpoint, and Cofense, other open-source tools, and white-label infrastructure such as Pavlov for teams that want GoPhish-style control without self-hosting and maintenance.

What is the best KnowBe4 alternative?

For a modern security-awareness platform to train your own team, Hook Security — Pavlov's preferred partner — is a strong KnowBe4 alternative, built on a psychology-based PsySec approach (humor and positive reinforcement). If you instead want to deliver simulations under your own brand or embed them in a platform, Pavlov's white-label, API-first model fits better.

Yes. GoPhish is free, open-source software released under the MIT license. You self-host it, which means you are responsible for deployment, security, deliverability, and ongoing maintenance.

What is a white-label phishing simulation platform?

A white-label platform lets a trainer, MSP, or software company run phishing simulations under their own brand rather than a vendor's. The simulation engine runs behind the scenes — often via API — so the end experience carries your name. This is the category Pavlov is built for.

Buyer's guide

Best phishing simulation tools & GoPhish alternatives (2026)

Updated June 2026 · ~7 min read

Short answer: there's no single best phishing simulation tool — it depends on who you are. Security teams running their own program tend to choose KnowBe4 for breadth or Hoxhunt for adaptive, gamified training; technical teams who want full control use the open-source GoPhish. The gap none of them fill well is white-label, API-first delivery for trainers, MSPs, and platforms who want to ship simulations under their own brand — which is what Pavlov is built for.

How to choose a phishing simulation tool

Most teams weigh five things. Be honest about which actually matter for you before comparing feature lists:

Who it's for. Are you securing your own employees, or delivering training to clients and end users on someone else's behalf? This single question rules out most tools.
Branding. Does the experience need to carry your brand (white-label), or is the vendor's brand fine?
Deployment. Self-hosted (you run it) vs managed SaaS (they run it) vs API/infrastructure (you build on it).
Content & training. Do you need a built-in library of templates and lessons, or do you bring your own?
Reporting & pricing. What metrics matter (click rate vs report rate), and does pricing scale with how you actually use it?

The main options in 2026

GoPhish — free, open-source, self-hosted

GoPhish is the most popular free, open-source phishing framework, released under the MIT license as a single binary. It gives technical teams complete control over their phishing infrastructure and data. The trade-off: you are responsible for deployment, email deliverability, security, and ongoing maintenance, and it has no built-in training content or vendor support. Best for red teams and engineers who want control and don't mind operating it. Compare Pavlov vs GoPhish →

KnowBe4 — the broad, established suite

KnowBe4 is one of the largest security-awareness vendors, with one of the biggest libraries of videos, games, quizzes, and an extensive phishing-simulation console, plus broad language and compliance coverage. Pricing is tiered and quote-based (Silver through Diamond). Some users find the default training compliance-driven compared with newer adaptive platforms. Best for organizations that want one broad, proven suite for their own staff. Compare Pavlov vs KnowBe4 →

Hoxhunt — adaptive, gamified training

Hoxhunt uses AI and behavioral science to deliver personalized, gamified micro-training, with continuous simulations calibrated to each employee rather than periodic blast campaigns. Best for larger organizations that want engagement-first, individually adaptive training. Compare Pavlov vs Hoxhunt →

Also worth knowing

Proofpoint leans on its global threat-intelligence network and suits compliance-heavy enterprises. Cofense (formerly PhishMe) is SOC-first and centers on report rate, with reported emails flowing into analyst workflows. Adaptive Security focuses on modern attack types like AI-generated spear-phishing and deepfakes. All are end-customer products rather than infrastructure you build on.

Where Pavlov fits

Pavlov is launching Fall 2026 — this section describes its product approach, not yet-shipped benchmarks.

Almost every tool above is an end-customer product: you buy it to train your own people, and your audience sees the vendor's platform. Pavlov takes a different shape. It's white-label simulation as a service, delivered by API and MCP, built for the people who deliver training — trainers, training providers, MSPs — and for software platforms that want to embed simulations as a native feature under their own brand. If you like GoPhish's control but not the upkeep, or you'd rather offer simulations as your own product than resell someone else's, that's the gap Pavlov is built to fill.

Preferred partner

Replacing KnowBe4 for your own team?

Pavlov is white-label infrastructure, so it isn't a like-for-like KnowBe4 replacement for training your own staff. For that, our preferred partner Hook Security is a modern security-awareness and phishing-simulation platform built on PsySec — a psychology-based approach that uses humor and positive reinforcement instead of fear and shame. It's trusted by 500+ organizations and 125+ MSP partners.
