Does this replace Microsoft's own email protection?

It works alongside it, not instead of it — layering additional detection on top of what Microsoft 365 already includes, rather than removing anything.

Will it slow down our email or flag too many false alarms?

It's designed to sit inline without noticeable delay, and tuned to reduce false positives over the ones basic filters produce — that tuning is part of what a managed setup gets right from day one.

Does it cover Teams and SharePoint too, or just email?

Modern email security platforms, including Check Point's, extend to collaboration tools like Teams and SharePoint — increasingly where attacks arrive via shared links, not just the inbox.

Check Point email security, explained simply

Check Point Email Security (formerly Harmony Email & Collaboration) works quietly in the background, catching threats most people never see. Here's what it actually does.

Quick answer Check Point's email security scans messages before they land in an inbox, catching phishing, impersonation and malware that basic filtering misses — and extends that same protection to Teams and SharePoint links, not just email.

What it actually does, in one sentence

Check Point Email Security checks every message — and every link inside every message — for signs of phishing, impersonation and malicious attachments, catching threats designed specifically to slip past Microsoft 365's built-in filtering.

What it catches that basic filtering often misses

Impersonation — an email that looks like it's from your CEO or a supplier, but isn't
Lookalike domains — a sender address that's one letter off from a real contact
Delayed-detonation malware — attachments that look clean at delivery but activate later
Malicious links in Teams and SharePoint — not just email

Why this matters for a small business specifically

Large enterprises have dedicated security teams watching for exactly this kind of attack. SMEs are frequently targeted precisely because attackers assume that layer doesn't exist — one convincing email is often all it takes to get a payment redirected or a credential stolen. This kind of protection puts an enterprise-grade layer in front of a business that doesn't have (and doesn't need) an in-house security team to run it.

The quiet part: good email security is invisible when it's working — you don't see the attacks it stopped, only the ones it didn't. That's exactly why it's worth having someone actually monitoring it, not just installing it and forgetting about it.

How this fits into a managed setup

Without a managed partner	With Cloudeli managing it
Installed once, rarely reviewed	Continuously monitored and tuned
Alerts go unnoticed	Alerts are triaged and acted on
No one owns the response plan	A clear incident response process

Where this fits with everything else

Email security is one layer — protecting the devices those emails are opened on is the other half of the picture. See Check Point Endpoint Security explained for what covers your laptops when someone does click something they shouldn't.
