The local picture
Counted from the register in September 2026. Credential figures reflect what each provider publicly evidences or has declared; only a listing marked independently verified has been checked at source by us. The website security scan is our own automated check of transport, header and email-authentication settings, which is a proxy for how a firm runs its own systems rather than an audit of the service it sells.

Managed Security (SOC) in Hertfordshire: common questions
How many providers offer Managed Security (SOC) in Hertfordshire?
3 providers on the WhatMSP register list Managed Security (SOC) among the services they offer in Hertfordshire, South East. Service lines come from what each provider publishes or has declared; where we detected one from the provider's own website rather than being told, the listing says so.
Do these Hertfordshire providers hold security certifications?
2 of the 3 publish at least one recognised security or quality credential, including 2 that evidence Cyber Essentials. Only a listing marked independently verified has had those credentials checked at source by us, so ask for the certificate number and expiry date before you sign anything.
Can a provider pay to appear higher on this page?
No. The ordering reads only earned signals: independently verified listings first, then the strength of the evidence we hold, then listings the owner keeps current, then alphabetically. It cannot read a billing or payment column, and an automated test fails the build if that ever changes.
Should the provider be based in Hertfordshire?
For remote work it matters less than it used to; for anything involving hardware, a move or an on-site review it still matters. This page lists local and regional firms first and shows UK-wide firms separately rather than mixing them in, so you can decide which sort of answer you want.
Data on this page comes from Companies House records, the credentials each provider publishes, our own automated scan of each website, and anything the owner has submitted. Only a listing marked independently verified has been checked at source by us. The scoring methodology and how we make money are both published.
