MSPs are now in scope: the supply‑chain crackdown
The Cyber Security and Resilience Bill explicitly targets the digital supply chain. Managed Service Providers are no longer just vendors - you are designated as critical infrastructure.
Why is the government targeting MSPs?
MSPs are viewed as "force multipliers" for cyber risk. A single compromised MSP can provide attackers with backdoor access to hundreds of client networks (as seen in the Kaseya and SolarWinds attacks).
The Bill aims to secure this supply chain by placing direct regulatory burdens on MSPs. You are now responsible not just for your own security, but for the inherent risk you pose to the UK digital economy.
MSP compliance obligations checklist
The core duties expected under the new framework.
1. Mandatory Registration
You must register with the designated competent authority, providing details of your services and critical assets.
2. Enhanced Security Measures
Implementation of "state of the art" security controls, including MFA, encryption, and continuous monitoring.
3. Customer Notification
If you suffer an incident, you must notify not just the regulator, but potentially all affected customers without undue delay.
4. Supply Chain Vetting
You must vet your own suppliers. The duty of care flows down - if your sub-processor fails, you are liable.
Is your IT provider a "Relevant MSP"?
The Bill creates a two-tier MSP market. Many generalist providers will not meet the "RMSP" standards - which can leave you non-compliant.
| Capability | Generalist MSP | Precursor (RMSP ready) |
|---|---|---|
| Incident reporting window | Business hours / best effort | Strict 24-hour (Section 15) |
| Vulnerability management | Patch Tuesday only | Continuous + "state of the art" |
| Supply chain liability | Unclear / limited | Full supply-chain accountability |
| Forensic capability | None (outsourced) | In-house DFIR team |
Turn compliance into competitive advantage
Don't just survive the regulation - lead with it. Market your MSP as "Bill 329 ready" to attract security-conscious enterprise clients.
