Email Security & Archive
Protected inboxes and a complete, compliant record of every message.
Checked 4 October 2026. Built from the full service page.
In short: Filtering, impersonation protection, continuity and an archive written outside the mailbox. Establish what your Microsoft licence already does before adding a gateway: for many estates the honest reasons to add one are continuity and archive depth rather than filtering.
Who this is for
The problem
One convincing phishing email is all it takes, and once it lands, a missing archive means you can't even reconstruct what happened. Meanwhile a mailbox outage with no continuity leaves the whole business unable to send or receive until it's fixed.
What we would do
Establish what your Microsoft 365 licence already does before adding a gateway. For many estates on Business Premium or E5, properly configured Defender covers the filtering, and the honest reasons to add a gateway are continuity, independent archiving and vendor separation rather than better detection.
- If you have a retention or production obligation, an archive held outside the platform that generates the mail is a materially stronger position.
- If an hour without email has a real cost, continuity is worth buying regardless of how good the filtering is.
When we are not the answer: If you are paying for a gateway whose continuity has never been tested and whose archive nobody searches, you are paying for a product doing nothing your Microsoft licence is not. We will tell you to drop it.
What is included

What the last 12 months looked like
What it costs
Scoped and quoted against your estate rather than sold from a rate card. We price what you already run, including the parts that are working and do not need replacing, and the quote itemises what is included so it can be compared line by line with anyone else’s. Managed IT support starts at £40 per user, per month if that is the wider question.
Three questions people ask
Isn't Microsoft 365's built-in protection enough?
Microsoft 365 gives you a strong baseline, but layered email security adds advanced anti-phishing, continuity during outages and independent, tamper-proof archiving.
What does email archiving give us that mailboxes don't?
A compliant archive keeps a complete, searchable, tamper-proof record of every message independent of the mailbox, so nothing is lost to deletion or mailbox limits.
What happens to email during an outage?
Email continuity keeps your people sending and receiving even if the primary mail platform is down, so a Microsoft 365 or Exchange outage doesn't stop the business communicating.
