If you’ve been treating the NIS Regulations as a set of suggestions, it’s time for a reality check.

The goal? To stop a single provider breach from becoming a national crisis.

𝗪𝗵𝗮𝘁 𝗶𝘀 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗰𝗵𝗮𝗻𝗴𝗶𝗻𝗴?

𝗟𝗼𝘄𝗲𝗿𝗲𝗱 𝗧𝗵𝗿𝗲𝘀𝗵𝗼𝗹𝗱𝘀:

"Minor" incidents can no longer be swept under the rug. Mandatory reporting is getting tighter and faster.

You are now legally on the hook for the security hygiene of your vendors.

𝗥𝗲𝗴𝘂𝗹𝗮𝘁𝗼𝗿 𝗧𝗲𝗲𝘁𝗵:

Expect formal "Notices of Intention" and "Remediation Notices." Failure to comply won't just result in a fine - it could lead to personal liability for directors.

The weak security days are over. Accountability is no longer a community goal - it is a 𝗹𝗲𝗴𝗮𝗹 𝗿𝗲𝗾𝘂𝗶𝗿𝗲𝗺𝗲𝗻𝘁.
