Mimecast Advanced Email Security: stop phishing, impersonation and ransomware before the inbox

Email is still where most attacks arrive, and built in filtering catches the obvious ones. The targeted ones, a lookalike domain asking finance to change bank details, a link that turns malicious an hour after it landed, are what get through. Mimecast layers click time link checking, attachment sandboxing, impersonation detection, DMARC enforcement, continuity and awareness training on top of Microsoft 365 or Google Workspace. C4C Group is an accredited UK Mimecast partner and reseller. We supply, implement and support it, and we tell you when what you have is enough.

What it does

Six things built in filtering does not

Links checked when they are clicked

URLs are rewritten and scanned at the moment of the click, not only on arrival, so a link that was clean when the email landed and weaponised an hour later is still caught.

Attachments detonated before delivery

Files are opened in a sandbox and, where needed, delivered as a safe version, so a document carrying ransomware never reaches the desktop as itself.

Impersonation and payment fraud caught

Display name tricks, lookalike domains, newly registered senders and the language of an urgent payment request are scored together, which is how business email compromise gets stopped rather than spotted afterwards.

DMARC to enforcement, and your brand protected

Reporting and analysis that gets your domains to a DMARC reject policy without breaking legitimate mail, and detection of lookalike domains and cloned sites that trade on your name outside your estate.

Email that keeps working when Microsoft 365 does not

Continuity gives users a working mailbox through a Microsoft 365 or Google Workspace outage, so an incident somewhere else does not become a day without email.

Awareness training that targets the right people

Short, regular training and phishing simulation aimed at the users who actually click, integrated with the platform so the risk score and the training line up.

Honest fit

Where it is the right buy, and where it is not

Right for

Organisations where email is the main way attacks arrive, which is most of them. Anyone who has had a business email compromise near miss, regulated sectors that must evidence controls, and Microsoft 365 estates where the built in filtering catches the obvious and misses the targeted. The free email security assessment on this site will show you whether that is you.

Think twice if

You already run Microsoft Defender for Office 365 at the top tier, it is properly tuned, and someone owns it day to day. In that case the gap may be smaller than a vendor will tell you, and we will say so. And if your losses come from people rather than payloads, start with awareness and human risk before adding another gateway. Do not run two email security platforms in parallel; pick one.

The question behind this page, whether built in email security is enough, is answered in our guide on built in email security, and the head to head is in Mimecast vs Microsoft Defender for Office 365. The attack it most needs to stop is covered in business email compromise, and the domain side in DMARC explained.

Questions

Frequently asked questions

What is Mimecast Advanced Email Security?

Mimecast Advanced Email Security is a cloud email security platform that sits alongside Microsoft 365 or Google Workspace. It scans links at the moment they are clicked, detonates attachments before delivery, detects impersonation and payment fraud, takes your domains to DMARC enforcement, keeps email running through an outage, and delivers awareness training to the people most likely to click.

Do I need Mimecast if I already have Microsoft 365 Defender?

It depends on which tier you have, how well it is tuned and whether anyone owns it. Built in filtering catches commodity spam and known malware well. Targeted impersonation, payment fraud and links weaponised after delivery are where a dedicated layer earns its place. C4C will tell you honestly whether your gap justifies it, and the free email security assessment is the quickest way to find out.

Does Mimecast stop business email compromise?

It is built to. Business email compromise rarely carries malware, so it slips past filters that look for payloads. Mimecast scores the sender, the domain, the display name and the language of the request together, so an urgent payment instruction from a lookalike domain is held or flagged before anyone acts on it. Training the people who approve payments closes the rest of the gap.

What is DMARC, and does Mimecast handle it?

DMARC is the email standard that lets you tell receiving mail servers to reject messages that claim to come from your domain but fail authentication. Getting to a reject policy safely means finding every legitimate sender first. Mimecast provides the reporting and analysis to do that, and C4C stages the move to enforcement so nothing legitimate breaks.

Can C4C supply and implement Mimecast email security?

Yes. C4C Group is an accredited UK Mimecast partner and reseller, so we can source, implement and support the platform as well as advise on it. Our independence is in the recommendation, our partnership is in the delivery and support. Where your existing protection is enough, we say so.

How is Mimecast Advanced Email Security priced?

It is licensed per user and priced on quote, depending on the modules, the user count and the term. C4C will give you a like for like quote, tell you which modules you actually need, and say what is negotiable. Send us your user count and your current platform and we will come back with a figure.
