- Published by KAYZEN, a Lyon-based business, with public prices and no hidden commitments.
The problem
Too many tools, too many alerts, too little time
A small business has no IT department to assemble five security products. Kayzen starts from that observation.
Tools that don't talk to each other
An antivirus here, a web filter there, updates done by hand: each tool has its own console, its own alerts and its own bill.
Alerts nobody can understand
Technical messages in English don't help a practice manager decide what to do. Every Kayzen alert explains what happened and what to do, in plain words.
Evidence that is hard to produce
Insurers, customers and auditors ask for proof. Kayzen prepares readable monthly reports, based on what the modules actually observe.
Our approach
Four principles, upheld in the code
One agent
One lightweight piece of software per device turns on the modules you need, with no reinstalling and no piling up.
A clear console
Fleet status, prioritised alerts and one-click actions, written for managers as well as technicians.
Data in Europe
Professional customers' data is intended to be held by a host whose data centres are in the EU.
Public prices
Prices shown per device per month, a 30-day trial with no credit card, simple cancellation.
The platform
Thirteen modules, one public roadmap
Each module shows its real status: pilot programme, in development or planned. Nothing is presented as available before it is.

Install the agent
A signed installer per device, or a silent deployment by GPO, Intune or script for an entire fleet (being finalized).
Choose your rules
Ready-to-use policies, adjustable by device group, signed before being sent to the agents.
Monitor and prove
Explained alerts, one-click actions and a monthly PDF report, in your language.

Frequently asked questions
Your questions, our answers
Is Kayzen Security available yet?
Not yet for the general public. The console and DNS filtering are in a pilot programme; the Windows agent and the antivirus are in development, and ransomware protection is planned. Each module shows its real status on the site.
Why is it free for individuals?
Because businesses and MSPs pay for their plans, and they are the ones who fund protection for families. There is no advertising, no resale of data, and no Kayzen Home protection feature is limited to push you to pay.
Do I need to uninstall Microsoft Defender?
No. To begin with, Kayzen works alongside Microsoft Defender, which stays active. The main protection mode will only be offered after the necessary technical validations and certifications.
Where is the data hosted?
Professional customers' data (telemetry, DNS logs, quarantine) is intended to be held by a host whose head office and data centres are in the European Union. The showcase website, which contains only public content, is hosted by Vercel.
Do I need technical skills?
No. Installation takes a few clicks and alerts are explained in plain language. Technicians also get bulk deployment, an API and advanced options.
Which systems will be supported?
Windows first, then macOS and Android. On iPhone and iPad, Kayzen will offer web, DNS and SMS protection: it is not an antivirus, because iOS does not allow files from other apps to be scanned.
How much does the business offer cost?
From €2.50 excl. VAT per device per month, with a 30-day trial and no credit card. Prices are public and may change before commercial launch.
Who publishes Kayzen Security?
Tarek BELHADJ EI, a sole proprietor trading under the name KAYZEN, based in Lyon (SIREN 493 857 262). Full contact details are in the legal notice.
