PhishingU versus KnowBe4, GoPhish and PhishingBox. Each of them is good for something different - here you will find a factual comparison by pricing model, Hebrew, setup time and regulation, so you can choose correctly.
| PhishingU (us) | KnowBe4 | GoPhish | PhishingBox | |
|---|---|---|---|---|
| Pricing model | A one-time payment per campaign, from ₪999 | An annual per-seat subscription (by quote) | Open source, free - self-installed | A per-seat subscription (monthly / annual) |
| Commitment | No subscription, no commitment | A seat minimum and an annual commitment | None (the tool is free) | An ongoing subscription |
| Hebrew and Israeli adaptation | Full Hebrew (RTL) and a certificate of participation in awareness training | An English interface, multilingual content | An English tool, with no built-in training content | An English interface, templates in 70+ languages |
| Setup and time | About 15 minutes, no technical knowledge* | Account creation and configuration | Server installation, SMTP and domains - technical knowledge required | Account creation and configuration |
| Report and certificate | A summary report + an awareness training completion certificate | Reports and a dashboard | Basic reports (no certificate) | Reports and a dashboard |
| In-person training by a CISO | Yes, optional (at the office or remote) | Digital training content (LMS) | None | Digital training content (LMS) |
| Who it suits | Small and mid-sized businesses in Israel that want a quick exercise in Hebrew | Large organizations with a continuous annual awareness program | Technical security teams that want a free self-installed tool | Organizations that want a continuous SaaS platform with an LMS |
* Setting up an exercise with PhishingU takes less than 15 minutes with no technical knowledge - one simple action is required from IT (allowlisting the sender), and launch is subject to a review and approval by the information security team, up to one business day.
The comparison is based on public information as of September 2026 and is intended for general orientation only. The features, products and prices of other vendors may change - we recommend verifying with each vendor. The names KnowBe4, GoPhish and PhishingBox and the trademarks belong to their lawful owners; there is no affiliation, association or sponsorship between them and PhishingU.
When PhishingU is the right choice
You run a single exercise from ₪999, a one-time payment. No minimum seats and no annual commitment - you pay only when you run it.
Templates, landing pages, a report and a certificate in Hebrew (RTL), with a certificate of participation in awareness training, which is evidence that helps meet part of the requirements of Amendment 13 (this is not a confirmation of full compliance with the law).
You build and run it yourself, with nothing to install and no server to set up. One simple IT action is required, and launch is approved by the information security team.
At the end you receive a summary report and an awareness training completion certificate. You can add a 60-minute awareness training by a CISO, at the office or remote.
Fairness is part of the point: for large organizations building a continuous annual awareness program, a subscription platform such as KnowBe4 or PhishingBox may fit. For technical security teams that want a free self-installed tool, GoPhish is a reasonable choice. PhishingU is meant for those who want a quick, one-time exercise in Hebrew - with no subscription and no infrastructure.
