Small businesses and SMEs
Cybersecurity for a small business or SME, without an IT department
A small business is rarely targeted for its own sake: it gets hit because a computer was not up to date, an email looked legitimate or a password had leaked. The key is to cover these common risks simply.
Kayzen Security is in a pilot programme: no customer references are cited on these pages, and no module is on sale yet.
The sector's challenges
Payment fraud
Fake supplier, fake CEO, altered bank details: a single mistake can cost a significant share of your cash.
Ransomware
Encrypted computers and servers often mean several days of downtime and lost data without an offline backup.
Lack of time
No full-time IT person: updates and alerts need to almost manage themselves, with a readable report.
Partner requirements
Cyber insurers, contractors and large customers increasingly ask for evidence of good practices.

Your questions, our answers
Do you need an IT person to use Kayzen?
No, that is the goal: an agent to install, recommended default settings and alerts explained in one sentence. A managed service provider can also run everything for you.
