Mimecast Collaboration Security extends Mimecast's threat protection beyond email to the collaboration tools employees now live in — Microsoft Teams, OneDrive and SharePoint. As work shifted into chat and file-sharing, attackers followed: malicious links and files shared in a Teams channel, or malware sitting in a SharePoint library, bypass an email-only gateway entirely. Collaboration Security scans the content flowing through these channels for malware, malicious URLs and risky files, applying the same detection Mimecast built for email to the collaboration surface — so a threat shared in Teams is caught the same way one arriving by email is. It is part of Mimecast's Human Risk Management platform, so a risky action in collaboration connects to the same view of human risk as email, awareness training and insider-risk signals. For organisations whose attack surface now includes Teams and SharePoint (i.e. almost everyone on Microsoft 365), it closes the gap an email-only tool leaves open. TechBag scopes, PoCs and quotes it in INR/GST.

Understand email security before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is collaboration security?
Threat protection for the collaboration surface — Microsoft Teams, SharePoint and OneDrive — scanning messages and files for malware and malicious links.
Mimecast’s email-grade detection, extended to the channels work moved into.
Unprotected inbox vs AI email security — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Unprotected / signature email | Collaboration Security (Mimecast) |
|---|---|---|
| The surface | Only email inspected | Teams, SharePoint & OneDrive too |
| Internal threats | Shared in Teams, invisible | Scanned and caught |
| File stores | Malware sits in SharePoint | Detected before it spreads |
| Detection | Email-only engine | Email-grade, on collaboration |
| The blind spot | Post-email surface unprotected | Closed |
| Management | A separate collaboration tool | One Mimecast platform |
| The context | Siloed alert | Connected human-risk view |
| Governance | No collaboration compliance | Extends via Aware |
Pairs with Advanced Email Security — the two surfaces people use most, protected together. Extend to Aware for governance.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Teams Protection
Scans messages and shared content in Microsoft Teams — the malicious link or file dropped in a channel, caught before a colleague clicks it.
SharePoint & OneDrive
Scans files in SharePoint and OneDrive for malware — the payload sitting in a shared library, detected rather than left to spread.
Email-Grade Detection
Applies the same threat detection Mimecast built for email — URL and file analysis, malware detection — to the collaboration surface.
Post-Email Coverage
Catches threats that never touch the email gateway — shared internally in Teams or a file store, they would otherwise be invisible.
HRM Platform
Part of the Human Risk Management platform — a risky collaboration action connects to email, training and insider-risk in one view.
One agent on every machine, one console over all of them — modules attach without a second operational world.
Twelve capabilities. Detect, remediate, connect.
Mimecast extends protection to the collaboration surface — email-grade detection on Teams and SharePoint, part of the portfolio, and paired with the human firewall.
Microsoft Teams Protection
Scans Teams messages and shared content for malicious links and files — the threat dropped in a channel, caught.
SharePoint Scanning
Scans SharePoint libraries for malware — the malicious file sitting in a shared site, detected before it spreads.
OneDrive Scanning
Scans OneDrive files for malicious content — personal cloud storage brought into the security picture.
Malicious-Link Detection
Detects malicious URLs shared in collaboration — the same link analysis Mimecast applies to email, on chat and files.
File Malware Detection
Analyses shared files for malware — the payload that skipped the email gateway, caught on the collaboration surface.
Automated Remediation
Removes or quarantines malicious content found in collaboration — the threat neutralised, not just flagged.
Closes the Post-Email Gap
Threats shared internally in Teams or a file store never touch the email gateway — this closes that blind spot.
Unified Management
Managed alongside email in the Mimecast platform — collaboration security in the same picture, not a separate tool.
Human Risk Signals
Feeds the Human Risk Management platform — a risky collaboration action connected to email, training and insider risk.
Pairs with Email Security
Extends the same protection from email to collaboration — the two surfaces employees use most, covered together.
Microsoft 365 Native
Built for the Microsoft 365 collaboration stack — Teams, SharePoint and OneDrive, where the work actually happens.
Aware Governance Option
Extends with Aware for collaboration governance and compliance — data loss, records and conduct across the same channels.

Here’s what genuinely sets Mimecast’s collaboration protection apart.
Work moved past email — attacks followed
Employees now spend as much time in Microsoft Teams, SharePoint and OneDrive as in email. Attackers noticed: a malicious link shared in a Teams channel, or malware sitting in a SharePoint library, reaches colleagues without ever passing through the email gateway. If your security only inspects email, that entire surface is a blind spot. Collaboration Security closes it — protecting the channels where work actually happens now.
Email-grade detection, on collaboration
This is not a lightweight bolt-on. Collaboration Security applies the same threat detection Mimecast built over two decades for email — URL analysis, file/malware detection — to the content flowing through Teams, SharePoint and OneDrive. A malicious link or file shared in collaboration is analysed the same way one arriving by email is, so the protection you trust on the inbox extends to the collaboration surface at the same standard.
One picture across the channels people use
Because Collaboration Security is part of Mimecast's Human Risk Management platform, a risky action in Teams or SharePoint is not an isolated alert — it connects to the same view of human risk as the user's email behaviour, their awareness-training status and any insider-risk signals. You see human risk across the channels employees actually use, together, rather than stitching a separate collaboration tool into the picture by hand.
Best paired with email security
Collaboration Security is most powerful alongside Mimecast Advanced Email Security: the two surfaces employees use most — email and collaboration — protected by the same detection, managed together, feeding one human-risk view. For a Microsoft 365 organisation, that pairing covers the two channels where the overwhelming majority of user-facing threats now arrive, rather than protecting one and leaving the other exposed.
Extends to governance with Aware
For organisations that need more than threat protection on collaboration — data-loss prevention, records retention, conduct and compliance supervision across Teams and other channels — Mimecast Aware (its own page) extends the same collaboration coverage into governance. Threat protection and governance on the same surface, from the same platform, is a coherent story for regulated industries whose compliance obligations now reach into chat.
The honest scope
Collaboration Security is a strong way to extend email-grade protection to the M365 collaboration stack, especially if you already run Mimecast for email. Microsoft's own Defender covers Teams/SharePoint natively if you are all-in on Microsoft E5; specialist collaboration-security tools exist too. Mimecast's edge is one platform and one human-risk view across email AND collaboration. TechBag scopes it vs the native Microsoft option for your estate.

Quick poll — what’s driving your evaluation?
Talk to an advisor“We secured email for years but Teams was wide open — a malicious file shared in a channel skipped the gateway entirely. Collaboration Security closed that blind spot.”
“SharePoint scanning caught malware sitting in a shared library before it spread. That surface was invisible to our email-only tooling.”
“Same Mimecast detection we trust on email, now on Teams and SharePoint — and managed in the same place. The consistency is the value.”
“Running email plus collaboration from one platform gives us one human-risk view across the two channels our people actually use.”
“We weighed Microsoft's native Defender for Teams — for an all-E5 shop that is capable. We chose Mimecast to keep email and collaboration in one platform.”
“Extending into Aware for collaboration governance was straightforward — threat protection and compliance on the same surface from one vendor.”
“Automated remediation removes the malicious content rather than just alerting — that saved us manual cleanup in SharePoint.”
“OneDrive coverage brought personal cloud storage into scope — a gap we had not fully appreciated until we saw what was there.”

What do email threats cost you?
Drag the sliders (count users; IT-hour cost as loaded incident rate). Estimates assume ~1.5 hours per user per year handling email threats that reach the inbox without AI filtering, with ~70% removed by stopping the mass at the gateway — the avoided-breach value (most attacks start here) is the larger, unpriced win. Illustrative.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models actual device counts and modules.

The 8 questions to ask every vendor
Take this into your next vendor call — including ours.
Confirm it scans all three — Teams messages/shared content, SharePoint libraries AND OneDrive files — not just one.
Verify collaboration content gets email-grade analysis (URL + malware), not a lighter check.
Test with a threat shared internally in Teams (never touching email) — is it caught?
Confirm malicious content is removed/quarantined, not just alerted — closing the loop.
Decide whether to run it alongside Mimecast email security for one platform and one human-risk view.
If regulated, scope Aware for DLP/records/conduct on collaboration — governance on the same surface.
If you are E5-heavy, compare Microsoft Defender's native Teams/SharePoint coverage honestly.
